Classic and Arcade modes with 10 levels from mild to insane. Also features next-piece preview, customizable keys and highscore. Perfect way to procrastinate.

[2009-08-12] Thank you very very much for the kind support from everyone since YAT's launch nearly four years ago until now. I am so glad to see that it has been downloaded 400 thousand times and probably enjoyed by thousands around the world everyday (including myself). Again, thank you for your support and I hope you like this game.

Version 2.52, 2006-1-26

Previous issues fixed - blocks can move faster and rotate should work better.

Version 2.51, 2006-1-15

Speed reduced, mainly in Arcade mode. Highscore now accepts longer names. Upgrading to this version should not affect previous highscores.

Version 2.50, 2006-1-13

LARGER blocks and a new low-level key-handling routine to make the game much more responsive to inputs (no more sore fingers).

Highscore added. More tweaks to game play.

Version 2.30, 2005-11-19

Version 2.20, 2005-11-14
