10-Pin Spare Conversion System & Math

The Fastest Way to a Higher Average

Strikes look great, but spare conversion is what wins leagues and tournaments. Missing two single-pin spares in a game costs you up to 22 pins. Mastering a repeatable spare system is the single fastest way to raise your average.

The 3-6-9 Targeting System

• Cross-Lane Angle: Always shoot right-side spares (10-pin, 6-pin) from the far left side of the approach, crossing the center arrow. Shoot left-side spares (7-pin, 4-pin) from the far right side.
• Plastic Spare Ball: Using a polyester spare ball removes oil pattern hook variability from the equation, giving you a straight ball path regardless of lane breakdown.
• Flattening Wrist Release: Breaking your wrist back at release keeps the ball end-over-end, preventing unintended side roll.
