Only the current version so far — new entries appear as the game ships updates.
In Puzzle Merge, you select a cell on the board to place a tile; arranging three or more tiles of the same type adjacently or in a straight line scores points and clears those tiles. Points awarded depend on the number of matching tiles. Every 10 moves, the tiles shift one space in a random direction. The goal is to reach a target score within a set number of moves for each level. Achieving the goal results in a win and a 100-point bonus, while running out of moves or filling the board completely results in a loss. Points can be used to purchase power-ups: swapping the positions of the two upcoming tiles, removing a single tile from the board, or using a lightning strike to clear all tiles matching the type of the upcoming tile.
