Golf is a sport where people hit a small white ball with different kinds of clubs and try to get it into a hole. There are lots of different variations of golf. In some versions, you can only use one type of club to hit the ball (called "one-club golf"). In other versions, you can use many different kinds of clubs and hit from different spots on the course (called "traditional golf"). Some variations have rules that change the order of the hole-by-hole play (called "scramble golf"). There are also versions that combine elements of different kinds of golf and make the game more complicated and challenging (called "multi-course golf").
