3D Bowling is ten-pin bowling with the parts that matter: a lane, an aiming line, a power meter and a spin control. You position the ball, choose the angle, set how much power and curve to put on it, and release. Strikes and spares score exactly as they do in a real alley, over ten frames.
The depth is in the angle. A ball rolled straight down the middle almost never strikes; the pocket — between the head pin and the one behind it on your strong side — is what clears all ten, and hitting it consistently means learning how much the spin bends the ball on its way down.
Ten frames of up to two rolls each. A strike (all ten on the first ball) scores 10 plus your next two rolls; a spare (all ten across both balls) scores 10 plus your next roll. A perfect game of twelve strikes is 300.
The gap between the head pin and the pin behind it on your dominant side — the 1-3 pocket for right-handers, 1-2 for left-handers. Hitting it is the most reliable way to strike.
