Chat Noir is a visually simple (but apparently impossible once you start playing) graphical puzzle in which you try to stop the black cat escaping the game board. The cat can't step on the dark circles, and you can darken one per move to try and corral the little kitty. I'm rapidly coming to the conclusion it can't be done, but it's so addicting I can't stop trying [via Jayis, subbed by JhInG]. UPDATE: It can be done, corralled the cat on the millionth go, but there's no reward for "winning" though :(
