Maniac Square is an action puzzle game with gameplay similar to Columns, but with pieces of only two parts and colours. Blocks drop down from the top of the screen and can be rotated. To create a match and make them disappear, at least three identical pieces need to be lined up horizontally, vertically or diagonally. Every now and then blocks contain a star piece that can be matched with any piece. The game is played at a fast pace with a time limit. To extend the time and continue playing the player has to form a certain number of lines. Progress is shown through a vertical Goal bar in the top right side of the screen. Multiplayer is supported for two players simultaneously, racing each other.
