Speed bowling
Speed bowling is a novelty format of traditional ten-pin bowling. It was invented on June 17, 2009 by Gregory Kohs.
Rules
Players must use a ball that is at least one-twelfth their body weight (up to 16 pounds). They have five minutes to complete as much of their ten-frame game as possible, using a single lane. The ball must not ever strike the metal "sweep" in front of the pins, as that is a disqualification, and the player's score will be zero for that game. Optionally, using a standard 2-lane system at a regulation alley, the player may alternate lanes to intensify the competition, and the sum of the two scores generated on the two lanes is tallied.
Speed threshold
If the alley is equipped with a radar gun mechanism (as found at various Lucky Strike alleys in the United States), the player's ball velocity down the lane must not be measured less than 16 miles per hour at any point in the game, or the player is disqualified.
Etiquette
Speed bowling is not to be played on any lane where non-competitors are engaged in standard bowling on any adjacent lane.
