There are ten rounds, or frames, in a game. In a frame each player is allowed to roll two balls. If he knocks all the pins down with the first ball, he has a "strike." If he knocks them all down with two balls, he has a "spare."
Scoring is rather complicated. The highest possible score in a game is 300. To get this the player must have a strike in every frame. Perfect games are not common, but neither are they rare.
Bowling was brought to the United States by early Dutch settlers. It was then called "skittles" and was played with nine pins instead of ten. The lawmakers thought that people were wasting too much time playing ninepins and passed a law against the game. But those who wanted to play soon found a way of getting around the law. They began using ten pins instead of nine.
