Move, rotate, and place the various blocks that the game automatically outputs, arrange them in one or more lines and eliminate the score.
The different shapes of blocks, which consist of small squares, continue to fall from the top of the screen. Players adjust the position and orientation of the blocks so that they can spell out one or more complete lines at the bottom of the screen. These complete bars disappear immediately, freeing up space for the new fall, while players get points for rewards. Blocks that haven't been eliminated continue to pile up. Once they are stacked on the top of the screen, the player loses and the game is over.
