The object of this simple but difficult online strategy game is to encicle the cat with dark green tiles. Every time you click on a tile, the cat hops. Can you surround him before he hops off the field?
Man... This Games is called "Chat Noire", not "Circle the Cat", and is one of the oldest Flash games I've ever played. Its more than 5 years old (16 Oct 2007)!
