The objective of the game is to use the pieces to create as many horizontal lines of blocks as possible. When a line is completed, it disappears, and the blocks placed above fall one rank. Completing lines grants points, and accumulating a certain number of points moves the player up a level, which increases the number of points granted per completed line. In most versions, the speed of the falling pieces increases with each level, leaving the player with less time to think about the placement.
