You have to trip the black cat that's trapped in a maze of balls. At the start of the game, you'll see a black cat sitting on a light green ball in the middle of the screen. Each time you click one of the light green dots, it will change to dark green. The black cat will run away from the dark green balls, and your goal is to get the cat to run off the screen. Once the cat is trapped, he will run off the screen. Try to get the cat to run off the screen in as few moves as possible. Once you clear the level, you move to the next level which is even tougher.
