The main aim of golf is to hit the ball from the tee to the green, and then knock it into the hole.
For each hole, there is a number of shots that experts think players should need to complete the hole, called par. The shorter the hole, the lower the par number.
There are 18 holes in a round of golf, and par is normally 72. The player who completes the 18 holes in the least number of shots wins.
A tournament is normally made up of four rounds of 18 holes.
