Plates of different shapes composed of small squares successively fall from the top of the screen. Players adjust the position and direction of the plates to make them form a complete one or several at the bottom of the screen. These complete bars will disappear immediately to make room for the newly-falling plates. At the same time, players will be rewarded with points. The squares that have not been eliminated continue to pile up. Once they reach the top of the screen, the player loses and the game ends.
