From Wikipedia, the free encyclopedia:
Tetris is a computer puzzle game invented by Alexey Pajitnov in 1985, while he was working for the Academy of Sciences in Moscow, Russia. Pajitnov has cited pentominoes as a source of inspiration for the game. The game (or one of its many variants) is available for nearly every video game console and computer operating system, as well as on devices such as mobile phones and PDAs. Tetris even appeared as part of an art exhibition on the side of a building. The game first gained mainstream exposure and popularity in 1989 when it was packaged with the original release of Nintendo's Game Boy. Tetris consistently appears on lists of the top video games of all time.
