Let's consider only the elementary case: a sphere, moving on diagonals — to the straight lines making with boards a corner in 45 °. At once there is an interesting question. Whether it is possible to predict in advance, to what of three (co-ordinates distinct from the beginning) billiard table corners the sphere if the sizes of a table are known will get? Certainly, we can always draw a trajectory of a sphere and learn the answer but if, for example, the table has the sizes 10,175 X
