Hey all, I'm a newbie but I thought I would share with everyone some good news. My wife got me a game called Go! Sudoku for the PSP. I'm not sure if it is on any other system/console, but it's awesome. There are something like 1000 puzzles and you can download more, though I don't know that I will reach that point.
Anyway, just thought I would share. Here is the site if you are interested.

The puzzle game is taking over the world!
