If Plinko, Pinball and Peggle had a love child, this might be it. Players draw pegs onto the screen in order to bump the ball into the target hole. The more spectacular bumps, the more gems you get.
The game features two modes of play, finite and infinite. In the Challenge (finite) there are 30 levels that get increasingly difficult. In Zen, Normal and Painful modes (infinite), levels are algorithmically generated with a specific difficulty and constant ball speed.
