Just a note on the referrals. The referred player (friend) has to bet 1x their deposit before the $50 referral bonus is paid out to the referrer.
B/c the 100 free bet does not count towards this requirement, I doubt if many refer-a-friends will actually qualify for the bonus. A lot of posters are prob. going to make the $100 freebet and nothing else.
