Bowling

Bowling is a sport where people roll a heavy ball. It was invented centuries ago when grenades were heavy iron balls. Two main kinds of bowling arose. In one kind the bowler rolls a ball near a target and knocks away the ball of another bowler. This kind includes lawn bowling.

In the more common kind nowadays, the bowler rolls the ball down a wooden bowling lane trying to knock down bowling pins. This kind includes ten-pin bowling, which is so commonplace that it is often simply called "bowling". Some people bowl at smaller pins, called "duck pins" or "candle pins" with slightly different rules.
