Mosaic Merge

Slide glowing tiles across a 5×5 mosaic board and watch matching numbers fuse into bigger ones! Mosaic Merge is a calm but addictive number puzzle: plan every swipe, build the 1024 tile, then keep going for a record score. Take back one slip per game and see how far your mosaic can grow.

How to play Mosaic Merge

Slide all the tiles at once with the arrow keys or WASD, or swipe on a touchscreen. Tiles slide as far as they can; when two tiles with the same number touch, they fuse into one tile with double the value, and that value is added to your score. Each tile fuses only once per move. After every move a new 2 or 4 appears. Press U (or the undo button) to take back your last move, once per game, and N for a new game. Your best score is saved in your browser. Build a 1024 tile to win, then keep playing for an even higher score. The game ends when the board is full and no tiles can fuse. Press M to mute. The game interface is in English. Ready to merge? 🔢
