SameGame's puzzle just sits there if you put down the TI-83 calculator. Insane Game by Martin Hock and Bill Nagel, on the other hand, adds an "action mode" that starts with the screen half-full and adds a shower of puzzle pieces; if the screen fills up, game over.

It's been cloned as part of freepuzzlearena, making it available for DOS, Linux, and Windows; get it at . There's a second action mode in this PC version in which the screen slowly scrolls upward; it's somewhat reminiscent of Tetris Attack.

Gnome sane?
