In Circle The Cat, the goal is to surround a gliding cat in a series of concentric circles, and you need to avoid the cat's exit by clicking on the dot. Originally developed in Flash, this version of the cat trap can be played in any modern web browser by emulating software. To create a wall, just click on the circles. Cats are notoriously hard to catch. If you start getting too close to the cat, it will find a way through your structures no matter how well designed they are.
After finding it and building a relatively wide, closed perimeter, you must next fill it with circles until the cat has nowhere to jump to. You have now completed a complete revolution around the cat and the game must now start over.
This game is played with the mouse.
