Figures composed of blocks appear at the top of the screen and go down vertically. You can move them to the left or right, or rotate them to fit the figures that accumulate at the bottom of the screen. Each line that is completed disappears and you gain one point. The goal is to make as many points as possible and to spend as much time playing before the pile of figures grows and prevents the arrival of new figures, ending the game. You can choose the falling speed of the figures. You can also choose to play with steady or incremental speed.
