Merge tiles by swiping in four directions and build higher values on a 4x4 board.

Play endless classic runs or open the challenge catalog with 50 fixed starting boards.
Each challenge uses a defined goal such as reaching a target tile, staying within a move limit,
or preserving a corner condition.

The game is fully offline and keeps progress on the device.
You can pause, undo the latest move, restart a round, and return later to a saved game.

Track your best score, highest tile, total moves, classic runs, and challenge clears.
Adjust swipe sensitivity, merge animation, theme, digit scale, feedback haptics, and tile texture
to match your preferred play style.
