Get rid of all the hollow pieces before the walls close in on you! Use quick reflexes and clever strategy for maximum points!
Match three or more colors to remove the pieces. Score combo points with chain reaction matches. After every 3rd dropped piece, a wall will move inward, compressing your game board, causing your pieces to shift. Will it be the wall on the left, right, or bottom? When will it happen? Learn the pattern to master the game!
