Teams will consist of 5 players. Each team will play 3 games and at the end of the event, the team with the highest combined scores wins. Other winners include person with most strikes, individual high score, most spares.


Game

A game of tenpins consists of ten frames. A player delivers two balls in each of the first nine frames unless a strike is scored. In the tenth frame, a player delivers three balls if a strike or spare is scored. Every frame must be completed by each player bowling in regular order.


Scoring

Except when a strike is scored, the number of pins knocked down by the player's first delivery is to be marked next to the small square in the upper right hand corner of that frame, and the number of pins knocked down by the player's second delivery is to be marked inside the right small square. If none of the standing pins are knocked down by the second delivery in a frame, the score sheet shall be marked with a (-). The count for the two deliveries in the frame shall be recorded immediately.


Types of Scoring

Strike

A strike is made when the full setup of 10 pins is knocked down with the first delivery in a frame. It is marked by an (x) in the small square in the upper right-hand corner of the frame where it was made. The count for one strike is 10 plus the number of pins knocked down on the player's next two deliveries.

Double

Two consecutive strikes is a double. The count for the first strike is 20 plus the number of pins knocked down with the first delivery following the second strike. 

Triple or Turkey

Three successive strikes is a triple or turkey. The count for the first strike is 30. To bowl the maximum score of 300, the player must bowl 12 strikes in succession.

Spare

A spare is scored when pins left standing after the first delivery are knocked down with the second delivery in that frame. It is marked by a (/) in the small square in the upper right-hand corner of the frame. The count for a spare is 10 plus the number of pins knocked down by the player's next delivery.

Error

An error is made when the player fails to bowl down all ten pins after two deliveries in a frame unless the pins left standing after the first delivery constitute a split.


Split

A split is a setup of pins left standing after the first delivery, provided the head pin is down and

At least one pin is down between two or more standing pins; i.e. 7-9 or 3-10.

At least one pin is down immediately ahead of two or more standing pins; i.e. 5-6.


Foul

A foul occurs when a part of the player's body encroaches on or goes beyond the foul line and touches any part of the lane, equipment or building during or after a delivery.
