When you swipe, all tiles slide in that direction. If two tiles with the same number collide, they merge into one tile with double the value and add those points to your score. Each tile can only merge once per swipe—a row of [2, 2, 2, 2] becomes [4, 4, 0, 0], never [8, 0, 0, 0]. A new tile (90% chance of 2, 10% chance of 4) appears after every valid move.

Lock your highest-value tile in one corner and build a descending chain along one edge. Avoid swiping in the direction that would pull your anchor tile away from its corner. Prioritize two directions (e.g., down and right) and only use the other two when forced. This "corner strategy" gives you the most consistent path to 2048 and beyond.

You lose only when the entire 4×4 grid is completely full AND no two horizontally or vertically adjacent tiles share the same value. If even one merge is still possible anywhere on the board, the game continues. You win by creating a tile with the value 2048.

The theoretical maximum tile on a 4×4 board is 131,072 (2¹⁷), which would require every cell to contain a power of 2 in perfect descending order. The maximum achievable score exceeds 3.9 million points. Most skilled players target 4096 or 8192 as a realistic personal best.

Math Merge uses the classic 2048 tile distribution: each new tile has a 90% chance of being a 2 and a 10% chance of being a 4. The occasional 4-tile adds strategic depth and prevents monotonous gameplay while keeping the difficulty balanced.
