How is cocked hat bowling scored differently from tenpin bowling?

In cocked hat bowling, the scoring system differs significantly from standard tenpin bowling due to the reduced number of pins and the maximum potential score per frame.

While both games allow two deliveries per frame, the scoring mechanics are adjusted as follows:

  • Maximum Frame Score: In tenpin bowling, a strike or spare is worth 10 pins plus the total felled in subsequent deliveries, allowing for a perfect game of 300. In cocked hat, the maximum score per frame is 3 plus the total pins knocked down with the next two balls, resulting in a perfect game of 90.12
  • Pin Configuration: Cocked hat is played with only three pins set at the corners of a standard tenpin formation, whereas tenpin bowling utilizes a full set of ten pins.21

Because of these differences, the cumulative scoring potential in cocked hat is substantially lower than the 300-point maximum found in traditional tenpin play.21
