Goal: get your ball into the glowing hole in as few strokes as you can. After 9 holes, the fewest strokes in total wins.
Players take turns. Each shot counts as one stroke.
Shooting: press on your ball, pull back like a slingshot and let go. The further you pull, the harder the shot. The dotted line shows which way it will start.
Planets pull your ball towards them, so shots curve. Use that to bend round them or slingshot past. Balls bounce and roll on planets.
Black holes swallow your ball, and flying off the course counts as lost too. Either way you get 1 penalty stroke on top of the shot, and the ball goes back to where you shot from.
