Remove the pins in the right order and make all balls go into the car.
Sometimes some of the balls are colorless: before they go into the car, they need to touch a color ball, so the color spreads to them as well.
Sometimes there are some bombs,they should be flipped away or detonated.
Sometimes there are some magnification gates.they need to go through the gates to reach the total.
Its easy and instresting, yet challenging.
