I know this will seem obvious to many, but the power of an extremely simple method will get you to level up considerably faster. The beauty of this system is that it's ridiculously easy. Before I share it, let's consider two golfers.
Adam plays one tournament round 6 days a week and rests on the seventh.
Billy Bob plays one round 3 days a week and plays one closest to the hole competition the other 4 days of the week.
After five weeks, disregarding all the bonus experience points earned, Adam will have earned approximately 24000 XP. After that same period, Billy Bob will have about 35000 XP, almost 50% more than Adam! And, you might notice, Adam will have played more than 50% more shots yet earn far fewer XP.
The point is simple--play every day if you want to rack up the XP quickly. The consecutive days bonus is huge if you keep it going. Even if you just drop in for a quick 9 shots on the CTTH game, it keeps your streak going, which means you will streak thru the levels much, much faster. And you know what that means...beautiful, new, shiny, fabulous virtual clubs available to you sooner to improve your game with.
Thought I would point that out, especially for the newbies (I'm one of them), because the game becomes even more fun with better clubs. At least I think so. Happy gofing!
