Tile Merge Challenge Swipe to move the tiles across the board. If two tiles with the same number touch, they merge into one, combining their values. The goal is to strategically match tiles to reach the highest possible number. Can you create the ultimate tile? Powers of 2: Tiles follow the series of 2, 4, 8, 16, 32, etc. How to Play: Swipe in any direction to move the tiles on the board. When two tiles with the same number collide, they will merge into one, doubling their value. The game ends when no more moves are possible. The challenge is to reach the highest number before that happens! Will you reach the highest tile, or will you run out of moves?
