While the cannon is moving, choose the right angle and tap to launch the ball. Your task is to get into the layer with layers from the first shot. In each level you have 3 shots and you have 3 energy points. For each lost level, 1 point is taken away for 15 minutes and gradually restored. If you don't have enough energy to play this level, wait for your energy to recharge or use Energy Refill to continue playing now!
