Hi zerealj,
Welcome to the forums! =)
You can't win cash directly, but we do have many tournaments and sweepstakes that are running 24/7. Some of the events are free to enter and some are paid entry. The prizes range from WGT Credits for upgrading clubs and avatars to Amazon/Golfsmith gift cards, real golf equipment and dream golf vacations.
There's always plenty to do, so enjoy yourself and have fun!
