The more complex the mechanism, the harder it is to find the fault and eliminate it. The main part of our Shaft car is an ordinary orange ball. If he is not in a special single place, which is intended for him, nothing works. Your task is to repair the car and for this you must change the direction of the arrows so that the ball can reach the circle without hindrance. Remember that the ball can not jump through even the smallest obstacles. But it can roll on any surface, regardless of gravity. If you are ready to start the mechanism, click the start button at the top of the screen.
