A random sequence of pieces falls. The objective of the game is to manipulate these pieces, moving from left to right and rotating 90 to 90 degrees, in order to create horizontal lines of blocks without holes. When you create one or more lines, they disappear, and the blocks above the drop. As the game progresses the tetrominos fall faster. The game ends when the pieces reach the top of the field where they play and can not drop new pieces.
