COCKED HAT.
The game is played with a head pin and the right and left corner pins as shown in the following diagram:
Balls not exceeding six inches must be bowled, and they must be rolled down the alley (not cast or thrown). The rules of American Ten Pins except in St. Louis, where there is a special association with local rules, generally govern this game also, with the exception of three balls instead of two to the frame, but strikes and spares count three instead of ten, and each pin counts one as in Ten Pins. If the bowler knocks down three pins with the ball which is first bowled, in any frame in the game of Cocked Hat, it is a strike, and counts three, and is marked on the blackboard the same as in Ten Pins. What pins the bowler knocks down in the second frame with his first two balls must be reckoned as in Ten Pins, i.e., one for each pin bowled down, which pin or pins must be added to the strike and placed to the credit of the player in the inning where the strike was scored (the strike being computed as three); such strike must be added to pins knocked down with the two succeeding spare balls; thus, should the bowler score a strike, and should he in the next new frame knock down but one pin with his two spare balls, the strike and pin scored must be computed as 4—the strike counting 3 and the pin 1.
Poodles, or balls rolled down the gutter, are fair balls, and any pin or pins which they may get must be counted and placed to the credit of the bowler; dead wood is removed from the alley, and any pins knocked down through dead wood remaining on the alley cannot be placed to the credit of the bowler. The maximum number which can be bowled is 90.
