When you have 3 dimensions to richochet a spherical object around in - it creates many more dimensions of complexity in which there are multiple solutions to get the 'ball in the hole'.
If you could have 'pockets' of dense and thin atmosphere for the 'ball' to pass through it would make for some interesting velocity considerations.
