You take your turn by clicking on a circle block the cat. After each turn the cat moves to another circle. You win the game when the cat has no more unblocked moves. you lose if the cat makes it off the game board.
Some starting arrangements are pretty easy and some are quite challenging. You need to think ahead and make the moves that most restrict the movement of the cat. Anyone who like puzzles, or cats, or both will enjoy wasting some time with this little puzzle game diversion.
