Number Merge Game Maker

A number merge game is a small board with deep strategy: swipe, watch equal tiles combine, and keep the board from filling up. Every move is simple, and every mistake is yours, which is why it is so hard to stop. Describe your version, the AI agent builds it as a phone game with exact merge rules, you play it in the emulator preview and download it as an Android APK. The idea above is the classic 4x4 board; change the size, the goal or the tiles before you build.

What your number merge game will have

From the idea above, the agent builds the full puzzle with rules that behave the way players expect:

The board — a 4x4 grid that starts with two small tiles on random squares.
Swipe controls — swipe in any of four directions and every tile slides as far as it can go; a swipe that moves nothing does not count as a turn.
Merging — two equal tiles that meet become one tile with double the value, and each tile merges only once per swipe.
New tiles — after every real move, a 2 or occasionally a 4 appears in an empty square.
Score and best — the value of each merge is added to the score; the best score is saved on the phone.
Undo and game over — one undo per move, and a game-over screen when the board is full and no merge is possible.

Features you can ask for

A goal tile with a "You win" screen, plus the option to keep going.
Board sizes from 3x3 to 6x6 with a separate best score for each.
A relaxed mode with unlimited undo and no game-over pressure.
A picture chain instead of numbers: fruit, planets, animals growing up.
A daily board where the new tiles appear in the same order for everyone.
Themes: warm paper, dark neon, pastel candy.
Keyboard arrow keys, if you also want a web game version.

Ideas to make it yours

Build a merge game with fruit instead of numbers: two cherries make a strawberry, two strawberries make an orange, and so on up to a watermelon, on a 4x4 board with a small guide at the bottom showing the whole fruit chain.

Build a relaxing 5x5 number merge game: unlimited undo, a calm night theme with soft piano sounds, a hint arrow that suggests a good next swipe, and a statistics screen with the best tile ever reached.

Build a merge puzzle for kids that teaches doubling: tiles show dots as well as numbers, each merge shows "4 + 4 = 8" for a moment, a 3x3 board, and no game over — the board clears and a star is awarded instead.

Get it on your phone

Press Build this number merge game and sign in with Google.
Play a full game in the emulator preview and test a row of three equal tiles to check the merge order.
Tune it by chatting: "faster slide animation", "a 5x5 option", "tile colors from yellow to deep red".
Press Download APK and install it on your Android phone; swipes feel best on a real screen.
For Google Play, build the signed version from the same menu; the APK builder page explains the steps, and the icon and name guide helps you give it an original identity.

Getting the rules exactly right

Merge puzzles feel broken when one small rule is off, so state the rules plainly. A tile that was just created by a merge cannot merge again in the same swipe; without this rule, a row of four 2s would collapse into an 8 instead of two 4s. A swipe that moves nothing should not add a new tile. New tiles should be mostly 2s, with 4s only now and then. The game is over only when the board is full and no two neighbors match, not simply when it is full. Once these rules hold, the fun is in the strategy — keeping the biggest tile in a corner, building chains along one edge — and players discover that on their own.

Frequently asked

How exactly do the merge rules work?

Every swipe slides all tiles toward one wall. Two equal tiles that meet merge into one, each tile merges at most once per swipe, and the pair closest to the wall merges first, so a row of three 2s swiped left becomes a 4 followed by a 2. Put these rules in your request and the game behaves the way players expect.

Can I change the board size?

Yes. A 3x3 board is short and tense, 4x4 is the classic balance and 5x5 is relaxed and long. You can also let the player choose the size on the home screen, with a separate best score for each.

Can the tiles be something other than numbers?

Yes. Two cherries can make a strawberry, two planets a star, two eggs a chick. Describe the chain from the smallest tile to the biggest and the agent draws or uses a picture for each step.

Can I publish my merge game on Google Play?

Yes. Build the signed APK and AAB from the Download APK menu. Give the game an original name and icon of your own rather than borrowing a famous one; the icon and name guide shows how to set them.
