Welcome to Fearless Jet Germ Crossbill

An offline rope-winding game, simple but really fun

Calculate the length of the rope and the diameter of the ball to determine the position of the nail. After the rope goes around the nail and the ball can hit the target smoothly, it is considered a successful level. With each level passed, the speed of the rope will be faster. Can you pass the level?
