Hello,

I am trying to figure out the mini putt logic… I understand that you give an angle and force then hit the ball. Now, once it hits a border, is it : the straight angle of the border minus ou plus (depending on the side) the angle of the ball that gives us the bounce angle? Any tips/formulas welcome 😃
