And play every day. 5 minutes of play each day will get you more than 1000 points. A lot more than skipping a day and only getting 30 points for skipping a few practice holes.
You probabably spend 5 minutes a day checking Facebook. Why not spend those same minutes accumulating enough XP points to help your club and collecting top virtual clubs that aren't available at level 25.
It took me a week to reach level 89 (that's 40,000 points to go from L88 to L89). It's also a nice ego boost to rack up four or five thousand points in a day..
I shoot for speed, not score. An 18 hole round making par ain't a bad accomplishment.
