DraftKings (available in iTunes) is believed to be the first fantasy app that incorporates golf (along with pro and college football and basketball, baseball and hockey). Fans can use the app to run their own free Masters pools--or hold similar weekly PGA Tour fantasy competitions.
If you want to run a league where more is on the line than simply pride, DraftKings also hosts individual leagues for a small commission based on the overall purse that's available.
The app offers several public golf contests with cash prizes for the winners, each requiring an entry fee to play. (Last week, I won $45 on a $12 entry fee for the Arnold Palmer Invitational.)
For the Masters, DraftKings is running a contest with $300,000 in guaranteed payouts, including a $100,000 prize to first place. The cost, however, is not for the faint of heart. To get into the game requires a $200 entry fee.
