Roll nine balls up the lane, hop the ramp, and drop them in the rings — 10, 20, 30, 40, the 50 bullseye, and the little 100 pockets tucked in the top corners.
Throw: press on the ball, flick upward and let go. The flick's speed is the power; its sideways slant is the aim. Keyboard: hold Space to charge the power meter, tap ← / → to aim, release Space to roll. Too soft and the ball rolls back for 0; a near-perfect full-power throw angled just right can drop a corner 100.
