Description from [Mobygames.com:][1]

"The original commercially-licensed version of Alexey Pajitnov's
classic Tetris puzzle game. Geometric shapes fall from the top of a
playfield to rest on the bottom; fit the pieces together, and the line
they form disappears. If the pieces don't form lines and eventually
stack up to the top of the playfield, the game is over. Difficulty
increases by dropping the pieces faster and faster over time.

Tetris is a verifiable classic game, translated to well over 200
electronic and computer platforms. It takes 2 minutes to learn, but a
lifetime to master."
