COCKED HAT AND FEATHER.
The pins are spotted as above, the centre pin being the feather.
Ten innings constitute a game, and three balls (not exceeding 6 inches in size) must be used in each inning.
All the pins except the feather have to be bowled down or the inning goes for naught.
If the feather is left standing alone, the innings count one.
There are no penalties. The dead wood must be removed. Any pins knocked down through dead wood remaining on the alley cannot be placed to the credit of the bowler.
The maximum is 10.
