In this video from Game Informer, Wozniak plays Tetris on the Game Boy while reminiscing about his time with the game. He apparently wasn't very good at the game when it first came out, but his son showed him the ropes. After that, he was one of the best players around. When Nintendo Power used to publish high scores in Tetris, he had the highest score for many consecutive months. He even had to submit his scores with his name spelled backwards because the folks at the magazine were tired of printing his name every month.
It's really interesting to see Wozniak talk about games since he himself has a history with the medium. He designed the original Breakout arcade cabinet and game, but Atari ditched the hardware design while keeping his original game design. It's a shame that he didn't stick with game development. It would have been really interesting to see what would have come of his ability to build gaming hardware.
