Tetris: You wanted Tetris - we've given you Tetris! You'll be addicted, but don't worry, you can come over and play as often as you want!

Use the arrow keys to control the blocks. Left and right to move it, down to drop, and up to rotate it.

Don't let anyone tell you that Tetris isn't habit forming. Ever since this game first appeared in arcades and then on the screens of game consoles and personal computers, it has needed a health warning.
