The last months Betfair have had a couple of similar Casino-promotions where it should be possible to win free-spinns in the casino. Right now they are running a "Free Spin Steeplechase"-promotion where you should pick one horse out of six and if it wins the virtual race you should win some free-spins. Have anyone ever won anything in those promotions? If the races were random you should win one out of six but I haven't won anything in more than 50 tries.
