Betfair is different. The Betfair Exchange connects you with punters all over the world to put up your own odds and place bets.

Once you have qualified for the offer, you must call 1-888-512-3887 to redeem your risk-free bet. Once your risk-free bet is credited you may use that by selecting the Use Free Play  option on the bet slip and can be used on straight bets (lines up to +140), two-team teasers, three-team and four-team special teasers.
