TEN PINS—HEAD PIN OUT.
ALSO KNOWN AS AMERICAN NINE PINS.
The pins are set as in the diagram.
Ten innings constitute a game.
Three balls (not exceeding 6 inches in size) are bowled.
One pin of the frame must be left standing, or the inning goes for nothing.
There are no penalties. The dead wood must be removed. Any pins knocked down through the dead wood remaining on the alley cannot be placed to the credit of the player.
The maximum is 10.
