Object: Avoid moving one of your Kittens into the diagonally opposite corner, e.g. the kitty corner. Movement can be straight or diagonal, but must always be towards the general direction of the opposite corner, never away from it. A Kitten moves by taking one step into an empty square. Kittens also capture, as in Checkers, by jumping over an enemy piece to a vacant square on the other side. Capturing is mandatory, and you must continue jumping and capturing as long as possible.

The losing player is the first one forced to move a Kitten into the opposite corner.
