Download and check out this game Puzze Pirates. (of course it's spyware and virus free so have no fear)
They give you a free 30 day trial and there is a way to continue playing for free, but I think I may still subscribe to this online game. It's kind of an MMORPG but really not. To do anything you need to play these tetris like puzzles. It's got a cool pirate theme and it's quite addictive. I bet you'd like it as a little diversion..
My characters name is Tug if you join up and want to find me..
