Pusher (1993)

Description from funagain.com

In Pusher, it is balls that are being dealt with. You have to push into the top of a triangle of other balls so that they roll away and find themselves a spot on the board. The question is, where do they roll to... your ball as well as your opponent's? And the answer to that depends on you, and your skill, instinctive feeling, and admittedly, a spot of luck.
