The 31 rule in bowling is a guideline to help bowlers determine their breakpoint on the lane when playing on sport oil patterns. When using the Bailey Bowling Ball Ramp, applying the 31 rule can help you aim the ramp so the ball exits the oil pattern on the ideal board. For example, on a 40-foot oil pattern, you would position the ramp to direct the ball toward board 9 (40 - 31 = 9), increasing your chances of hitting the pocket and striking, even if you need extra assistance to deliver the ball.
