The game of American pins (meaning that the number of pins is ten) consists of ten frames. Each player is given two tries in each of the first nine frames, except when he hits a strike. The player who hits the strike or the spa in the tenth frame has the right to use three tries. A ball is considered to have been sent correctly when it rolls off the player’s hand and crosses the line of throw into the playing track. A strike is called when a player properly sends a ball and knocks down all the pins on the first attempt to frame. Spé is celebrated when a player knocks down all the pins with two balls in one frame. An error occurs if a player using two balls in one frame fails to knock down all the pins, provided that the remaining pins do not split.
Split is a pin configuration in which:
– at least one pin is knocked over between two or more pins that continue to stand, such as in a 7-3 or 3-10 combination;
– at least one pin is knocked down directly in front of two or more pins that continue to stand, such as in combination 5-6.
