Waves Modes

Look what you've done - you've unleashed a flood of seeds across the latter two pages!

The "waves modes", which were added in v2.3, are DIVE variants with the flair of other modes, which replace those modes on the menu when the waves have been unleashed. To access them, go to DIVE and click the "Unleash the Waves" button - this was hidden within DIVE (rather than placing these modes on the regular menu screen) because it's expected that you have played and are familiar with DIVE before you play any of these. As of now, only Pages 3 and 4 have any waves modes; this may change in the future if ideas for waves modes of Page 1 or 2 modes are thought of, but I find that somewhat unlikely, as Page 3 and 4 modes often have much more of a defined gimmick to them than Page 1 and 2 modes do. If you wish to return to dry land and remove the wave-spread seeds from these modes, go to DIVE-3, the mode that replaces DIVE itself when the waves are unleashed, and click the "Retract the Waves" button there.

Basics of the 2048 Power Compendium

The 2048 Power Compendium is a collection of 100 different variations of the game 2048. You've probably already played, or at least heard of, 2048, but if you haven't, here's a summary:

A game of the original 2048 in the 2048 Power Compendium

2048 is a game that's played on a 4x4 grid of tiles. On each move, you choose one of the four orthogonal directions, and all the tiles slide in that direction until they hit another tile or the edge of the grid. The tiles are solid to each other, but if two tiles of the same number collide, they merge into a single tile with twice the number: two 1s merge into a 2, two 2s merge into a 4, two 4s merge into an 8, and so on. After each move, a new tile spawns. The game continues until the grid is full and no more merges can occur, at which point you're out of moves and the game is over. You win by reaching the 2048 (2¹¹) tile, but if you're good enough at the game, it's possible to get even higher tiles.

A game of 2187, which uses powers of 3 instead of powers of 2

There are many 2048 variants out there on the internet - what makes the 2048 Power Compendium special is that it's a collection of a bunch of variants, and while a few of the variants originated elsewhere, most of them are unique to the 2048 Power Compendium. When you first open the 2048 Power Compendium, you're looking at the menu screen, which contains the first 25 modes. Click on one of the tiles on the grid there to go to a screen that explains what that mode is. On that screen, you can change the dimensions of the grid, then you can begin a game in that variant by clicking the "Start Game" button. Each mode has different merging rules - the later modes tend to be more complicated than the earlier ones, so it's recommended that (at least for the main modes) you start at the top-left and work your way across the different modes from left to right, top to bottom (like how you read words on a page).

Note that there are a few differences between the 2048 Power Compendium and other 2048 variants. Unlike most 2048 versions, the 2048 Power Compendium does not have an automatic game over check, but if you try to move in a direction and nothing happens, that direction goes black until the next successful move, and it's game over once all directions have failed. The 2048 Power Compendium supports arrow key controls, WASD controls, and clicking the direction buttons to move, but unlike other 2048 versions, swiping the screen is not supported. If you feel that the movement animation is too fast or too slow, then click "Go to Modifiers" on the menu and change the animation speed there (It's recommended that you don't alter any of the other modifiers other than Animation Speed Multiplier until you've played a few games and gotten used to the various modes). Progress isn't automatically saved, but you can save your progress yourself by clicking "Get save code" in the middle of a game and copying the code there, then clicking "Resume From Save Code" on the menu and pasting that save code there when you want to resume the game. Also, upon finishing a game, there's an option to get a save code to view a replay of that game.

If you have any other questions, then read on. Otherwise, click "Return to menu" and enjoy the 2048 Power Compendium!

Modes

The first 25 modes of the 2048 Power Compendium

Each mode of the 2048 Power Compendium is a 2048 variant with different merge rules, and different tiles that arise from these merge rules. Most of the modes are based on powers of a certain number: 2048 uses powers of 2, 2187 uses powers of 3, 1024 uses powers of 4, and so on. A few modes use powers of a certain number offset somehow, such as 2047 (powers of 2, minus 1) and 2059 (powers of 3, minus powers of 2). 5040 and XXXX are special, as both of them combine previous modes or powers somehow. Unlike 2048, most modes have "intermediate" tiles: for example, in 2187, there's a tile for each power of three, but also for double each power of three, which means the possible tiles are 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, and so on. Each mode has a default grid size, but feel free to play on a differently-sized grid (by clicking the plus and minus buttons next to the grid width and height on the gamemode explanation screen) if you find the default grid size for that mode too hard or too easy.

Once you've played some of the regular modes and have a handle on the differences between each mode, you can click the "Switch Pages" button on the menu. This lets you switch between the four pages of modes, each of which has 25 modes, for a total of 100. The four pages each have a different overall "feel" to them: Page 1 consists of the standard modes centered around powers of numbers (which is, at least in theory, the central theme of the Power Compendium), Page 2's modes also play in a standard 2048 fashion but don't have as much "powers of numbers" focus (and some of the later ones are a little different in gameplay to a standard 2048 mode), Page 3's modes are more open-ended modes with multiple pathways of possible tiles (and, in some cases, different goals entirely than getting to particular tiles), and Page 4's modes are defined by various weird gimmicks that set them apart from the rest of the modes.

Not all of the 2048 Power Compendium modes will be equally fun - try out various modes and find your favorites!

Mode Modifiers

The mode explanation screen for XXXX

In addition to allowing you to change the grid size, some of the more advanced modes have "mode modifiers", options that let you change specific aspects of that mode, often relating to the exact details of the merge rules or the spawning tiles. In particular, several modes (many of which are on Page 3) include a "random goals" modifier, since those modes often have enough possible tiles that you may want to aim for tiles other than the given win conditions when replaying that mode. Some of these mode modifiers are changed by clicking plus/minus buttons, some of them are changed by clicking "Switch this Modifier" buttons, and some of them are changed by entering their new value into the provided textbox.

Gameplay of XXXX with the "Discovered Tiles" box clicked to alter its appearance

I didn't know where else in the guide to put this, so I'll mention it here. Some modes have more statistic boxes alongside the score, such as showing how many different tiles you've seen in this round. If one of these statistic boxes has a border around it, that means that box can be clicked to alter its display: for example, Discovered Tiles boxes can be clicked to change them between showing the amount of discovered tiles and showing all of the discovered tiles individually.

Settings

The first page of the Settings screens

The "Settings and Modifiers" button on the menu will first take you to the Settings, two pages of options that you can customize. These aren't settings that should affect the gameplay much, so feel free to customize them to adjust your experience with the game. The first page consists of settings that are either for convienience or for choosing whether or not to display various statistics during the game, and the second page consists of settings that let you save some data through page reloads (Note: these reload preservation settings set cookies, in case you're someone who cares about that). Some of these settings are changed by entering values into textboxes, others are changed via clicking their buttons or the "Switch this Modifier" buttons beneath them. Click the blue and orange arrows next to the page number to switch between the pages.

Modifiers

Clicking "Switch to Modifiers" in the Settings to switch to the Modifiers pages, which contain a bunch of different gameplay modifiers you can change. These modifiers affect EVERY mode (for the most part), and they allow a pretty good degree of customization. The Modifiers selection screens are split up into six pages - to switch between them, click the blue and orange arrows. Unlike the Settings, all of these modifiers alter the gameplay, so it's recommended you don't start changing the modifiers until you're comfortable with the variants themselves. Games resumed from save codes retain their old settings regardless of what the current modifiers are set to.

The first page of the Modifiers screens

The first page contains modifiers with numeric values, which are changed via the plus and minus buttons. When it comes to the "Randomly-Placed" modifiers, "holes" are, well, holes in the grid (which effectively act as walls), "block tiles" are tiles that move with the others but can't merge with anything (even themselves), and "slippery tiles" are spaces on the grid that tiles will slide right over (as if the slippery tile isn't there).

The second page of the Modifiers screens

The remaining pages have modifiers that are changed by clicking their respective "Switch this Modifier" buttons. The second page has modifiers that change some more basic elements of the gameplay, the third page has modifiers that alter the grid and movement directions, the fourth and fifth pages are where the most game-changing modifiers are found, and the sixth page lets you add moves that trigger automatically. If you decide to enable either of the fourth page modifiers, you should probably play on a larger grid than you otherwise would! Some modes have special interactions with a couple modifiers, with Negative Tiles in particular having the most special interactions.

Custom Grid

I wonder what that "Activate Custom Grid" button does?

Page 3, by default, only offers a few options for the shape of the grid: square, diamond, checkerboard, hexagonal, triangular (made of hexagons), and 3D/4D... but if you want to customize it further, you can click the "Activate Custom Grid" button. Doing so enables you to fully customize the grid by turning page 3 into two pages: one to customize the grid, one to customize the movement directions.

Ah, so that's what it does!

The grid customizer is the easier of the two custom grid screens to use: you can change the dimensions of the grid, you can switch the grid between square tiles and hexagonal tiles, and you can click on any tile to switch what it starts as: a regular empty tile, a hole in the grid, a box tile, or a slippery tile. You can't make any tile start as a number tile, though, since different modes have different tiles and the custom grid applies to every mode.

The directions customization screen, with the up arrow button selected.

On the directions customization screen, you can alter the direction buttons freely. To alter a specific button, click on that button. Once a button is selected, you can fill in the textboxes to change its attributes. When it comes to movement magnitudes, -1 vertical is up, +1 vertical is down, -1 horizontal is left, +1 horizontal is right, +1 vertical and +1 horizontal is southeast, and so on. +2 vertical is downwards movement that skips every other tile, so tiles jump directly from their current space to the space two tiles below them (These directions are different on a hexagonal grid). The five modifiers with "(%)" next to them are measured in percentage of the arrows box, where 100% is the entire box. To change which keys on the keyboard correspond to each direction, click the "Remove Last Key" and "Add New Key" buttons; the former removes the last keyboard key in the list for that direction. The "Add New Key" button, when clicked, becomes "Listening...", indicating that you should press a key on the keyboard; if the key you clicked isn't already assigned to a direction, then it will be added to the currently selected direction. The "Remove This Direction" button does what it says it does. To un-select a direction, click the direction that's already selected; if there's no direction selected, then you can click the "Add New Direction" button to add a new direction.

Custom Mode

The screen you see before starting the Custom Game process

The 2048 Power Compendium has quite a few modes already, but what if you have an idea for a mode that isn't already in the game? That's what the Custom Game is for! Going through the process of creating a Custom Mode will let you create your own mode that can be played in the 2048 Power Compendium, including a save code you can use to share the mode with others if you wish. In the process of creating a Custom Mode, you'll decide what tiles can spawn, what the allowed merges are, how the tiles are colored, the color of the background elements, and more. Modifiers will work on Custom Modes just as well as they'd work on any other mode, too.

The Custom Mode has its own Guide, so this Guide won't go into detail about it. Clicking the "Make a Custom Mode" button will take you to a screen where you can choose to create a new mode, load a Custom Mode save code you already have and re-edit it, or view the Guide for the Custom Game. As with this Guide, it's recommended you read the Custom Mode Guide before making your first Custom Mode.

Credits

Almost all of the code for this project was written by MathCookie, but not all of it:

• The feature of viewing replays of finished games was implemented by Quasitruncated Hexahedron.

• The following things were made by Pointless in his Extended Alternate 5040 mod: 12 of the Alternate 5040 variants (3125, XXXX, 3375, FACTUP, 180, X^Y, 2520, 10, Harderer 1762, Turatin, and Ratio-Fill 1296), some mode modifiers for the 2047, Partial Absorb 243, and Partial Absorb 257 variants, and Multicolor Tiles.

While everything in the 2048 Power Compendium other than the above was coded by MathCookie, many of the concepts came from other places first. 2048 was created by Gabriele Cirulli, and the official version can be found here. However, those who are familiar with 2048 probably already know that the true origin of the concept comes from Threes!, which is a premium mobile game with a free web version here; the 2048 Power Compendium's 3072 is based on Threes!. As for the other modes and modifiers in the 2048 Power Compendium that originated elsewhere:

• I can't seem to find the origin of 2187 (powers of 3), but it definitely existed before I added it to the 2048 Power Compendium.
• 3125 (powers of 5) comes from this Scratch project, which was also made by me, years before I made the 2048 Power Compendium.
• 1000 (powers of 10) is basically 20 Euros, a currency-merging 2048 variant.
• XXXX, specifically its behavior when the minimum and maximum merge length are equal, is inspired by 243.
• 2584 (Fibonacci numbers) shows up in dozens of alternate 2048 apps, though I don't know where it originated from.
• Isotopic 256 comes from here.
• Wildcard 2048 was inspired by Quantum 2048, but it's simpler than Quantum 2048 because I still don't quite understand the exact rules of how quantum tiles in that game merge.
• DIVE comes from here.
• The waves mode FIVE comes from here.
• Holes in the grid and box tiles are inspired by an old Android app called 2048 Sandbox, which has since been removed from Google Play.
• A hexagonal grid version of 2048 exists in several places. The 3D/4D grid modifier is based on 2048 4D.
• The non-interacting version of negative tiles comes from -512, while the interacting version comes from ±64.
• Automatic moves were inspired by the gravity special mode from 2147483648.
• The "hidden tile numbers" modifier was inspired by the similar option in this DIVE variant.

• The following modes and modifiers were suggested by Michael Darrow: Partial Absorb 361 (including its PA378 variant), 3,188,646, 3026, 1847, FACTUP, 3385, SCAPRIM (including its Integer Ratios Only variant), 2058, the Partial Absorb 243 variant of Alternate 5040 (which inspired the creation of Alternate 5040 as a whole and was then backported into the default ruleset of PA243 in v2.2), the "1+1+1=1.5+1.5" variant of 2216.838, the "1+0.5=1.5" mode modifier in the Partial Absorb variant of 2216.838, the "merge number changes based on merges instead of turns" Turatin mode modifier, the "tiles can merge with the previous negative tile" 2584 mode modifier, the Partial Absorb 19,683 variant of Partial Absorb 243, the "integer ratios only" variant of SCAPRIM, the "maximum outcome" DIVE seed checking modifier setting, the Full Grid Moves mode modifiers in Partial Flow DIVE, Tricolor Tiles, the "chance of occurring" automatic moves property, clicking Discovered Tiles boxes to switch their display, and some elements of the structure of the Custom Mode maker. Partial credit also goes to him for Bitwise 2048, the "also spawn 2s" modifier in TRIGAT, and Three-Tile SQUART.
• 16+16i and Partial Absorb 377 (including the PA233 variant) were suggested by Toni Brown.
• Partial Absorb 257 was suggested by aren12345, as was the Dual-Tile DIVE seeds mode modifier in Div-Add-Tor. Partial credit also goes to him for Level 0 of 2700 and 2205.
• Isotopic DIVE was suggested by F1e308.
• The 2520 variant of Alternate 5040 was suggested by marouane.
• The Turatin variant of Alternate 5040 was suggested by Hyper.
• Hidden tile colors was sort of a collective suggestion by a couple of these people.

• v2.1.14 (Jun. 4, 2025): Fixed the following bugs: a typo in Odds-Only 3069, X^Y becoming freeplay merges when block tiles were present, save codes breaking on modes with merges of more than two tiles, random goals in 3026, and interactions between random goals and Negative Tiles in several modes.


• v2.1.15 (Jun. 15, 2025): Fixed a typo where the 147 tile was 149 instead in 2401, and fixed an incorrect text color in Pro-Add-Uct with Interacting Negatives.

Added the ability to view replays of finished games (credit to Quasitruncated Hexahedron for implementing this feature!). Added two new variants (Partial Absorb 257 variant and SCAPRIM variant) and two new base options (primorials, custom base cycle) to Alternate 5040. Added random goals to 2700, 2205, 3240, 3385, 3307, X^Y, 378, 2295, and Directional Merges. Added several more mode modifiers: changing the base in Bitwise 2048, Timeless 2295, Partial Absorb 233 (which is a modifier for PA377), changing the maximum same merges in a row in 2669, Unordered and Coprime (232, 240), changing the exponent and whether ratio or product matters in 3385, Harder 1762, SCAPRIM (Integer Ratios Only), Homogenous 3240, two Eisenstein integers variants of 16+16i, changing how two +1s merge in 1321, Three-Tile SQUART, merge ratio in 1847, start and increment adjusting and a "half of the tiles are negative" mode modifier for mod 27, Levels 0 and -1 of 2700 and 2205, spawning 2s in TRIGAT, merge length options for 2496, FACTUP, and Pro-Add-Uct, and a more customizable merge length option for XXXX and 180. Changed 2216.838's mode with ÷2 tiles to use box spawns. Fixed a couple bugs with large numbers in Wildcard 2048, fixed Alternate 5040 (1668 Variant) with a base of 2, fixed bugs with Interacting Negatives in 900 and SCAPRIM, and fixed a bug where the text disappeared when loading a save code of a game with Tricolor Tiles enabled.


• v2.2.1 (Jun. 24, 2025): Fixed a bunch of bugs and typos that v2.2 added, because as it turns out that release was very buggy. (Bugs related to replays with certain modifiers have not been fixed yet)


• v2.2.2 (Jun. 26, 2025): Fixed bugs involving replays that included automatic moves or random goals, fixed a UI issue upon winning a game that the replay option was causing, changed the default grid size of two-tile merge Partial Absorb 255 to 3x3, and added Partial Absorb 378 (a modifier for Partial Absorb 361).


• v2.2.3 (Jul. 16, 2025): Fixed the following bugs: The continue button showing up in winning game replays, Partial Absorb 270's win condition being set incorrectly, 10 not being affected by positive and negative spawn ratios with Negative Tiles on, and a bug with Alternate 5040 (Partial Absorb 257 Variant)'s merges. Also, added a Partial Absorb modifier for 180.


• v2.2.4 (Jul. 27, 2025): Fixed a bug involving random goals in replays in certain modes (such as 3385), fixed rules displays not updating when returning to the original settings in 2496 and Pro-Add-Uct, fixed the crazy modifier display not updating when the merge length is different from normal in FACTUP, fixed a bug with Interacting Negative Tiles in Bitwise 2048, made the positive/negative spawn ratios work in 1825, and fixed a couple other bugs, including incorrect win conditions in multiple modes. Also, added pausing and speed changing during replays (credit to Quasitruncated Hexahedron for implementing this).


• v2.2.5 (Sep. 3, 2025): Fixed hidden tile numbers not working on wildcard tiles in Wildcard 2048, fixed a bug with the combination of Multitile 2048 and all crazy spawns in Wildcard 2048, fixed 0 tiles being creatable in Melting Pot Wildcard 2048 with Interacting Negatives, fixed the broken display of ÷2 tiles in 2216.838 with Negative Tiles on, fixed a merge order bug in 625, and fixed some other small bugs.


• v2.2.6 (Sep. 5, 2025): Fixed the following bugs: Maximum Merge Length in 2496 not working when Negative Tiles is on, the "A tile that was just merged can itself be part of another merge on the same move." and "To merge tiles, you must move in the same direction twice in a row." modifiers breaking the game, Ratio-Fill 3375 and Ratio-Fill 9261 not properly checking which tile in the merge is the largest (which could create tiles that don't properly promote to the next tier; a version of the previous behavior that doesn't have that issue has been added as a mode modifier for these modes), the border on Visible Next Spawning Tiles to indicate which tile(s) are about to spawn disappearing, Garbage 0s preventing seeds from unlocking in DIVE, and save codes not correctly loading a few modifiers (such as the tiles spawned per turn modifiers). Also, added "maximum outcome" to the seed checking mode modifier options in DIVE.


• v2.2.7 (Sep. 13, 2025): Fixed some Pro-Add-Uct merges with Negative Tiles giving negative score, and fixed a bug with random goals in Specific-Length 180.


• v2.2.8 (Sep. 28, 2025): Fixed tiles appearing in Discovered Tiles twice in Specific-Length Partial Absorb 180, fixed temporary holes and slippery tiles appearing in Discovered Tiles lists, and fixed bugged merge results in Pro-Add-Uct with Non-Interacting Negative Tiles.


• v2.2.9 (Nov. 8, 2025): Fixed the following bugs: modes with box spawns not resetting their boxes on game restart, 900 having merges not work in randomly specific circumstances, some score and merge bugs in 180 with Interacting Negatives, and a few internal bugs.


• v2.3 (Nov. 24, 2025): Added the first thirteen waves modes: Aquatic 2496, Aquatic 1845, Aquatic SQUART, FRUSEE, HICEM, Wildcard DIVE, Gaussian DIVE, Dual-Tile DIVE, Div-Add-Tor, Partial Flow DIVE, DOFFET, RACUTE, and DIVE-3 (go to DIVE if you want to access these). Added Temporary Holes as a Garbage Tiles option, and fixed the long-standing bug where mode modifier buttons can clip into the "Return to Menu" button.


• v2.3.1 (Nov. 25, 2025): Un-hid v2.3 (which was hidden as a mere "v2.2.10" when released). Fixed new replays being broken (replays generated in v2.3 still won't work, but replays from before then or from this point on should), added the Seeds Seen box to Dual-Tile DIVE, seed eliminations in Partial Flow DIVE no longer give score, and DOFFET's description now properly updates to mention that negative offsets change the spawning tiles.


• v2.3.2 (Nov. 29, 2025): Removed the "spawning tile can't be larger than the largest discovered tile" rule in Aquatic 2496 by default (because it allowed trivial chaining to exponential scores; there's now a mode modifier to bring it back if you wish), added options for extra turns after the grid fills up before the game ends in Partial Flow DIVE, and added a mode modifier to Div-Add-Tor to make seed checks work like in Dual-Tile DIVE. Fixed a bug where Alternate 5040's goal with base cycle could be 1 if the first base was huge, and fixed a bug where the "seeds are unlocked permanently" mode modifier in Unordered Dual-Tile DIVE did not work.


• v2.3.3 (Jan. 17, 2026): Fixed the following bugs: Negative Tiles causing equal-tile merges in Aquatic SQUART to give score, negative scores with Negative Tiles in Aquatic 1845 and Partial Flow DIVE, Dual-Tile DIVE seeds not working correctly with negative tiles, and several bugs with Div-Add-Tor.

Fixed the following bugs: Div-Add-Tor with unordered (232, 240) merges and Interacting Negatives having 0 tiles possible, three-tile merges 54 + 27ω having the wrong merges entirely, DOFFET merges giving score like a DIVE variant instead of like a regular mode, Ratio-Fill 1024's tier colors not progressing further for very large tiles, Garbage 0s not working correctly from Modifiers save codes from older versions, the hidden tile numbers modifier not correctly hiding seed numbers in seed announcements in waves modes, and a few other small bugs.


• v2.3.5 (Mar. 30, 2026): Fixed bugs with the following: DIVE's "first n primes" spawning tiles description, 2049's win condition with interacting negatives, and merges of leftover × tiles in 3,188,646.


• v2.3.6 (Mar. 31, 2026): Fixed a bug with random goals being enabled under mode modifier settings they shouldn't be allowed in in SQUART, FACTUP, and 3385.


• v2.3.7 (May 8, 2026): Fixed a small bug with modifier save codes, fixed huge tiles in 1429, and fixed new entries to conic gradients in Custom Mode colors not starting at 360 degrees like they should.


• v3.0 (Jul. 15, 2026): Added modding tools to create "Infused Modes" (import the word "Infuse" (without the quotes) into any save code slot to access them. See the CalcArray documentation for more information). Added the Settings to the Modifiers pages, with three pages of these Settings, including toggles for statistic boxes, toggles for memory optimizations, a toggle for what Restart Game does, and toggles for saving some things on page reloads. Added two new waves modes, FIVE and Isotopic DIVE. Added the following content from Pointless's Extended Alternate 5040 mod: 12 new Alternate 5040 variants (3125, XXXX, 3375, FACTUP, 180, X^Y, 2520, 10, Harderer 1762, Turatin, and Ratio-Fill 1296), some mode modifiers for the 2047, Partial Absorb 243, and Partial Absorb 257 variants, replaced Tricolor Tiles with Multicolor Tiles (credit to Pointless for implementing all of the things in that sentence!). Also added the RACUTE variant of Alternate 5040 and the hidden tile colors modifier from the Extended Alternate 5040 mod (these were made by MathCookie). Added the Direction Cooldown setting for the "moving in the same direction" modifier, and added "empty space where tiles can't spawn" and "block tile where tiles can't spawn" Custom Grid tile options. Added a mode modifier for Interacting Negatives behavior to 3385 and added support for switching ratio to product in the any-power version of 3385, added mode modifiers for which tiles decay and what they decay into to Isotopic 256, added the n^n version and a mode modifier for what happens when a disappearing merge should occur to 2058, added "Merges Between Splits" and "merges occur between two/three tiles" to Partial Absorb 270, added a modifier to only allow merge lengths coprime to the modulus in mod 27, and added mode modifiers for the merge rule and the spawning tiles to RACUTE. Added an option to include an icon tile for Custom Modes. Made several touchups, bugfixes, and internal changes.


• v3.0.1 (Jul. 16, 2026): Fixed various small bugs and typos from v3.0.


• v3.0.2 (Jul. 17, 2026): Fixed a bug where certain modifiers/settings could crash saved games on reload, and fixed a couple typos.


• v3.0.3 (Jul. 27, 2026) [Current Version]: Fixed a bug with the 3375 variant of Alternate 5040, and fixed a couple other smaller bugs.

Intro to Custom Modes

The 2048 Power Compendium has quite a few modes already, but what if you have an idea for a mode that isn't already in the game? That's what the Custom Game is for! Going through the process of creating a Custom Mode will let you create your own mode that can be played in the 2048 Power Compendium, including a save code you can use to share the mode with others if you wish. In the process of creating a Custom Mode, you'll decide what tiles can spawn, what the allowed merges are, how the tiles are colored, the color of the background elements, and more. Modifiers will work on Custom Modes just as well as they'd work on any other mode, too.

The Custom Mode is designed to allow for the creation of modes where the progression of tiles follows a single cyclic path. This mainly refers to modes in the style of the modes on Page 1, but also includes the first three rows of Page 2. All of these modes can be recreated in the Custom Game, but modes beyond that point are generally beyond what the Custom Game can be used to create. When creating a Custom Mode, each tile has a numeric index: for example, in a 2048 recreation, 1 would be Tile #1, 2 would be Tile #2, 4 would be Tile #3, 8 would be Tile #4, 16 would be Tile #5, 32 would be Tile #6, and so on. It is these index numbers that you have to work with when deciding merges and tile color schemes.

Alright, let's get into explaining each step of the process of creating a Custom Mode.

Spawning Tiles

A replication of 2048's spawning tiles

The first step to making a Custom Mode is deciding what tiles can spawn, and how likely each one is to spawn. For each index starting from 1, you get to choose what the number on that tile is and how likely it is to spawn. Use the "Add a New Spawning Tile" button to add higher indices to the list. A tile's spawn chance determines how likely it is to spawn: a spawning tile with spawn chance 2 is twice as likely to spawn as a spawning tile with spawn chance 1. If, for example, you want Tiles #2 and #3 to spawn but not Tile #1, then just set Tile #1's spawn chance to 0 - if a tile's spawn chance is 0, that tile can't spawn anyway so its value in the list of spawning tiles is ignored. The values of the spawned tiles must be whole numbers, but the values don't have to be positive - tiles whose values are 0 or negative are allowed, though if there are any negative spawning tiles then the Negative Tiles modifier won't work on that Custom Mode since it already has negative tiles.

Normally, tiles spawn with random chance, like in most modes. If you instead want spawning to work the way it does in modes like 1535 1536 1537, where there's a "box" that spawning tiles are pulled from (to ensure a more even spread of spawning tiles), the "Each tile has a random chance to spawn" button can be clicked to change it into (or back from) the box behavior. When the spawning tiles are in box behavior, the spawn chance is replaced with the amount of that tile in the box.

Merges

A replication of 2187's merges

The merges are the most important part of making a Custom Mode. Each merge has a few properties to it: which tile indices the merge can apply to, what the input tiles of the merge are, whether the merge must be ordered, and what the output tile of the merge is. What a merge does with the indices is up to you to decide, but what it does to the tiles' visible numbers is not: the numbers of tiles in a merge are always added, so if a 4 tile and a 5 tile merge, they'll always merge into a 9 tile, regardless of what those tiles indices are internally.

There are two options for deciding how to restrict a merge to certain indices (you can switch between these two forms via the "Change Form" button): either you can outright specify specific indices it works for, or you can make it based on a minimum, maximum, and modulo structure: for example, if the rule is 1 ≤ n ≤ 30 and n = 2 mod 3, then n must be 2, 5, 8, 11, 14, 17, 20, 23, 26, or 29, i.e. n must be between 1 and 30 and it must be 2 more than a multiple of 3. If you wish for there to be no maximum, leave the maximum box blank (this sets the maximum to Infinity). Note that if you try to enter, say, 5 mod 2, it will automatically be set to the equivalent 1 mod 2, so when editing these boxes you should probably edit the second modulus box before the first one. When specifying specific indices, enter a number into the blank textbox at the end of the list to add a new allowed index, make a textbox blank to remove that allowed index and all of the ones after it.

Merges can be as long or short as you want them to be. One of the tiles in the merge will always be "Tile n", where n is one of the allowed indices for that merge, and you set the other input tiles relative to that one. Input tiles are typically n plus or minus some number, but you can use the "Change Form" button below each input tile to switch it between n + c form and just c, where c is a number. This, for example, lets you make a merge where regardless of what n is, one of the tiles in the merge is a 1 (for 2047-style modes). The output tile also takes such a form.

A merge cannot have more than one output tile, but it can have no output tiles (if you want to make a merge where the colliding tiles are just destroyed). If a merge only has the single "Tile n" input tile, then it becomes more of an "effect" than a merge, an effect that applies to any valid tile at the end of each move (like the decaying in Isotopic 256). If multiple merge rules could apply at once, the merges earlier in the order of merges apply: for example, if you have a mode where both 1+1 and 1+1+1 are valid merges, then you need to put the 1+1+1 merge earlier in the Custom Mode's merge order, otherwise the 1+1 merge will take priority.

If you click the "The input tiles can be in any order" box, it changes to "The input tiles must be in the right order", which means that merge only occurs if the input tiles line up correctly: the first "Tile n" must be the tile colliding into the rest of the line, and so forth from there, with the last input tile being at the end of the line. This can be used to recreate the Bicolor modes, among other things.

Consistency Check

The result of running the consistency check on a 1296 recreation

Aside from the spawning tiles, you don't directly decide what the numbers on the tiles are: the numbers arise naturally as a consequence of the spawning tiles and the merges you choose. The consistency check is a chance for you to confirm that the numbers are doing what you designed the mode to do, i.e. that your mode is working as intended. Pressing "Run the check" will run some code that examines the mode to figure out what the first few tiles' numbers are, and then once you've done the check you can click "View Generated Tiles" to see what the tiles' numbers will be.

The check might come across an "inconsistency" and stop early: this means that, within the merge rules you've set up, it's possible for a tile with the same index to have multiple values, such as if Tile #5 was creatable as both a 6+2 merge and as a 3+9 merge (meaning Tile #5 could be an 8 tile or a 12 tile). This usually isn't something you'd want to have, since a tile's behavior in a Custom Mode is determined only by its index, not by its value. That being said, if you want this behavior, the Custom Mode process won't stop you.

Tile Colors

An example of a color rule

Choosing the colors of tiles is often the hardest part, or at least the longest part, of creating a Custom Mode. Color rules have the same possible restrictions as merges in terms of what tiles they apply to: you can either specify which tiles they apply to directly, or follow a minimum, maximum, modulo rule. As with merges, if multiple color rules could apply to a single tile, the earliest one in the order applies first. Color rules can take a while to set up, so unlike with merges (where the "Add a Merge" button adds a new default merge to the end of the list), the "Add a Color Rule" button adds a duplicate of the color rule you're currently looking at to the end of the color rule list.

For each color in the background of a tile, you get to choose its color via one of the three typical computer color systems: RGB, HSL, or HSV. HSL is used by default, but you can use the "Change Color System" button to switch to one of the other two. The box next to the "Change Color System" button is not clickable: it's a visual aid that shows you the color you currently have selected. The text box next to that lets you enter a hex code for a color, if you'd rather do that than set each of the three aspects separately. The color you choose for a given color rule is technically only the starting color for that rule (where you can choose the start point via the "At Tile #" box), as below the part where you choose the starting color, you can choose how the color varies as the index increases. For each aspect of the color, you can choose whether that aspect linearly increases, or gets exponentially closer to (or further away from) a particular value.

The background of a tile doesn't have to be a single color - it can be a gradient. Use the "Add a Gradient Entry" button to add another color to the gradient. Once a tile's background has more than one color, some additional properties become relevant. The Gradient Position box lets you adjust the order and positioning of each color in the gradient. Gradients come in three types: Linear (the gradient goes from up to down by default. This can be changed via the Gradient Direction box), Radial (the gradient goes from center to outside), and Conic (the gradient starts at the top and loops around in a circular path. The starting angle can be changed). Linear and Radial gradient positions work in percentage (out of 100), but Conic gradient positions work in degrees (out of 360).

The text color of the tile is also part of a color rule. The text can only be one color, not a gradient, but unlike the background, its transparency can be changed: α = 1 is fully opaque, α = 0 is invisible, and anything in between is partially transparent.

Background

The background color for a 2048 recreation

This screen of the Custom Mode lets you change the colors of five things: the background of the mode while you're playing it, the background of the "mode select" screen for the mode (the screen that lets you change the grid size and such), the color of empty spaces on the grid, the color of the back of the grid (the space between the empty spaces), and the color of the text within the mode (the rules text and such). These colors are chosen in the same way as the tile colors are. The two backgrounds can be gradients, but the empty spaces, grid back, and text color can only be single colors.

Other Stuff

The last Custom Mode screen for a 3125 recreation

The final screen of the Custom Game has a few assorted items that didn't fit anywhere else.

First of all, this is where you decide which tile(s) you need to make to win the mode. These are decided by index, and you can decide how many "winning tile candidates" there are and how many of them you need to discover in order to win. If the Amount Required to Win is N/A, then the mode cannot be won. There's also options for Losing Tiles: if you discover enough of these to hit the Amount Required to Lose, it's game over even if the board hasn't filled up yet. A typical 2048 Power Compendium mode doesn't use this mechanic, but I figured I'd throw it in.

This screen is where you decide the rules text of the mode. This isn't automatically generated - you have to specify it yourself. The first box is where the "heading" of the mode would go if it has one (like "Powers of 4" for 1024), the second box is for the title of the mode, and the third box is for the description of the mode. You do not get to make the text that describes the spawning tiles; that text is automatically generated.

By default, the default size of the grid for a Custom Mode is 2 more than the length of the longest merge in the mode, but you can change that default here if you wish. To accomodate for different grid shapes from the Modifiers, the default grid size must be a square - you can't set the default length and width separately. Of course, as with regular modes, the default grid size is just that: a default, which the player of the mode can still stray away from.

Custom Mode Save Codes

The screen you see upon completion of a Custom Mode

Upon finishing the creation of a Custom Mode, you're given a save code for that mode. You should copy this code and save it somewhere. Later, you can paste this code into the "Resume from Save Code" screen from the main menu to jump into playing that Custom Mode without having to recreate the whole mode, and (by nature of being a string of text) you can share the save code with others if you wish. You can also paste a Custom Mode save code into the screen reached from the "Load from a Save Code" button on the Custom Mode's beginning screen if you wish to edit that Custom Mode.

Examples of Custom Modes

To help you get familiar with the Custom Game process, here are some recreations of existing modes within the Custom Game. Click one of these boxes to show its save code, and load these save codes to get a sense of what a finished Custom Mode looks like.

...and, to show off what the Custom Modes can do, here's some new modes that I felt were good enough to make but not quite unique enough to add to the Compendium more properly.

To see more examples of Custom Modes people have made, click the button below.

If you want to make a mode more advanced than what the Custom Mode Maker is capable of, you'll probably want to create a modded mode, which means you'll need to know how to program modes into the game. The 2048 Power Compendium has in-built tools for creating modded modes known as "Infused Modes". To access and learn about these tools, import "Infused" (without the quotes) into any save code slot, or click the button below:

Intro to Infused Modes

Before v3.0, there were two ways to create your own Compendium modes. The Custom Mode Maker can only make modes in the style of Pages 1 and 2, but it's usable by non-coders and its modes work with the Modifiers and other such features. The other way is "injected modes": modifiying the game's code, then saving your resulting mode as a mode save code. This method is more versatile, but it requires coding knowledge, and Modifiers don't work because the save codes are of already-started games/modes.

Infused modes are a formalization and improvement of the latter approach - a more "proper" way to make modded Compendium modes. You'll still need to know how the Compendium's code works to make them, but they're able to be much more properly integrated into the Compendium once made, including supporting Modifiers and even being added to the title screen menu - and, like the other two methods, they can be shared and used even by those who don't know how to make them.

The Infused Mode tools are accessed by importing the word "Infused" (rather than by a button on the menu) because you're expected to be familiar with the game before you use them - they're modding tools, after all. This guide won't explain how the code works - to learn about that (which you'll need to know to make Infused Modes), check out the CalcArray Documentation.

Creating an Infused Mode

The first few lines of the Infused Mode creation interface

Creating an Infused Mode is done by clicking the "Create a New Infused Mode" button and then editing the many (over 40 as of now) variables that compose a mode's rules, graphics, and other characteristics. The strings you enter here will be imported as JSON into the appropriate variables when the mode is played (albeit an extended version of JSON that can, for example, support the BigInt 5n via the string "@BigInt 5"). Unlike injected modes, infused modes have a pre-game screen and can have mode modifiers, so there are variables here that control those things too.

Rather than starting from scratch, you can use the "Load a Save Code" button and enter an @2048PowCompInfused, @2048PowCompMode, or @2048PowCompCustom save code, then import that and it will load in as an infused mode. @2048PowCompInfused codes load their values directly, while the latter two are converted into infused modes using their gameplay values, with some blanks filled in with defaults for the pre-game screen values.

I'm not going to explain all of the variables here, as that information fits better in a context with the rest of the coding information. The explanations for what all the Infused Mode variables are, and what forms they need to be entered in, is in Part 5 of the CalcArray documentation.

Infused Grid Manager

The Infused Grid Manager with some example modes infused into it

The Infused Grid Manager allows you to take finished infused mode save codes and add them to the title screen of the Compendium. Here, you can click one of the tile slots on the grid, then paste an @2048PowCompInfused save code into the text box that appears, and click "Infuse to this Tile" or "Replace this Infusion" to infuse that mode into that slot of the grid. ("Drain this Tile" will remove that infused mode from that slot). You can also infuse @2048PowCompCustom and @2048PowCompMode codes into the grid this way, though note that the latter will still be an injected mode (i.e. it will jump immediately into the game, with no pre-game screen and no Modifiers support).

Once modes have been infused into the grid, these grid pages will show up as additional pages on the title screen after Page 4. Any page that had no modes on it will be removed once you exit the Infused Grid Manager. These infusions persist through reloading the page, so (until you clear your browser's data or somesuch) these infusions can be pretty much permanent, as if you've added a mode into the Compendium.

Here are some examples of infused modes, both to show off what they can do and to provide some examples so you can see what a finished infused mode looks like.

Welcome to the Office 0f Secrets.

We have been monitoring the 2048 Power Compendium since v2.1, and we have traced the signatures of what we believe to be a few secret modes, hidden somewhere within the Compendium. Who hid these modes, and for what reason, we are not certain, but we believe they are more... exotic than your typical 2048 mode, even compared to the rest of the Compendium's modes. If you wish to find them, we have uncovered clues as to how to unearth them. Good luck in your search, secret hunter.

(We have also given each secret mode a five-letter spoiler code, which will be revealed once the mode is found. This way, if you find yourself in an online discussion with fellow secret hunters, you can use these codes to indicate which secret mode is being discussed without outright revealing it outside spoiler markings, so others know whether it is safe for them to open your spoiler-ed message. The spoiler code for discussion of the Office 0f Secrets itself is ZOSHC. This system was suggested by Michael Darrow.)

We may be a secretive organization collecting information, but we care about information on hidden modes, not people. We have the capability to track which secret modes you've found even through page reloads as long as you report back here, but we'll only track that information if you want us to.

Congratulations on finding every secret mode!

As a reward, we'll let you in on one last secret: enter "View Color Schemes" (without the quotes) anywhere in the Compendium where save codes are imported and import that, and you'll get to look at tiles of your choice in some of the Compendium's more "special" tile color schemes. (This will work even if you aren't registered as having found every secret, but color schemes of secret modes will be hidden if you haven't found those... though right now there are not any secret modes with their own special color schemes.) [This was added back in v1.2, but had remained completely hidden until we found it.] {Spoiler Code: TVRCE}
