What is the quickest way to level up
WGT may have fixed this trick, but I know it was working as recently as a few months ago. Load up starter balls and play 9 holes. Whiff every shot from the tee until you max out at 10. It's even better with 18, but try 9 just to see if it still works.
I don't remember how big the bogey bonus was, but it was substantial. One of the guys in my CC used this to hurry up to get a shiny new driver, he'd been coveting.
It's possible the XP boost would apply to these as well.
This is how you whiff. Meter should look like this when shot is done.
