Hints & Tips

More attributes
Simply play in the tour modes. After you finish the putting, driving, etc., you will receive more attributes.

Increase composure
Use this trick in a two player mode if your composure is low and you want to raise it without using a Beating Token. When your teeing off, hit the ball at 100%. While the ball is in flight, press Mulligan. Your composure will go up without losing a Beating Token.

New clubs and challenges
After you finish the skins mode or match play, you will receive new clubs and new challenges for that mode.
