About Tetris

Tetris is a computer puzzle game invented by Alexey Pajitnov in 1985. Tetris is believed to be the best selling game ever due to its ports onto almost every system ever made.

The Object of the Game

Tetrominoes or tetrads, shapes composed of four blocks each, fall down a well and the player has to rotate and/or move them with the aim of creating a horizontal line of blocks with no gaps. When such a line is created, it disappears, and the pieces above (if any) fall. The seven possible pieces used in Tetris are referred to as I, T, O, L, J, S, and Z. All are capable of single and double clears, I, L, and J are able to clear triples, and only the I has the capacity for the four simultaneous clears that is known as a "tetris."
