The Guide Line, Accuracy, and Power are properties of the Clubs. 

1. Clubs with larger Guide Line values can help create a farther shot by it being in reach. 
2. Clubs with larger Accuracy values slow down the speed of the aiming pointer to make your shots more accurate. 
3. Clubs with larger Power values can make balls fly a longer distance. 

Upgrading Clubs increases these properties, which helps you take perfect shots.
