Tetris started life on a wind-up PC clone in the Soviet Academy of Computer Sciences in Moscow. Since then it's become one of the most converted games in the history of the world, a smash-hit coin-op worldwide, and is to become a handheld game in the very near future.
Why? Well, you tell us, and maybe we'll all become millionaires. But Tetris is laughably simple, infuriating and completely and utterly addictive, challenging both your mind and reflexes to their limit.
It's based on the rotation of shapes as they fall down the screen. You've simply got to slot them neatly into one another to stay alive. Sounds silly, but once you start playing, we bet you won't stop. Absolutely unmissable.

The most playable of the 8-bit games. Totally addictive - a classic puzzle game.

Brilliant to play, and has a stunning 20-minute soundtrack on this version. Your Commodore shouldn't be without it!
