How to play
Use the arrow keys (or swipe on touch) to slide every tile on the board in one direction. When two tiles with the same number collide, they merge into their sum. Each move spawns a new 2 or 4 in a random empty cell. The game ends when the board is full and no merge is possible.
Strategy that actually works
Pick one corner and never let your largest tile leave it. Most players lose because they use all four directions freely — keeping to two directions plus one occasional third keeps your big tiles anchored and your merge chains intact. Build your rows in descending order so merges cascade instead of stalling.
