Single block Tetris, with high scores saved, plus a difficulty setting as well. (Boring under about level 8).
This method definitely works just fine, but you could condense it down a bit and eliminate both the 'total' and 'die' variables altogether.  Since we aren't really doing anything with the output other than displaying it, you could just make this into a one liner without any variables at al.. but that's really just splitting hairs on otherwise perfect code
