Chance rotations

With the knife comes the rotation. With the ball you neglect it, but with knife it is crucial. Because you have no control over the rotation, each throw has a different result.

Statistical throwing.

Thumb calculation. For sticking the knife, it must hit the target within plus or minus 18 degree. Makes within 36 degree. One Rotation has 360 degree, and 36 degree is one tenth of it. Each tenth knife will stick. This is 10 % score.
