One of the most popular video games ever created, Tetris® has defined puzzle gaming for over a decade on every game system.

And, now, with Tetris Worlds™ Online Edition, you can play online and enjoy all the cool features of Xbox Live, including voice chat and online high-score rankings. There's even a new Lounge Chat game mode—a non-competitive environment, where the emphasis is on the social aspect of playing, rather than keeping score.

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.
