One of the most popular video games ever created, Tetris® has defined puzzle gaming for over a decade on every game system. Tetris is deceptively simple, yet, completely addictive. Small shapes called Tetraminoes fall from the top of the Playfield to the bottom. Players must rotate the Tetraminoes as they fall and fit them together to complete lines. When the player fills an entire line with blocks, that line is removed from the screen. If the player cannot complete lines, the blocks will eventually rise past the top of the screen and the game ends. Sound easy? Once you start, you can't stop.
