You need no deposit for the first 50 spins. However, you must enter the code CASF51 when you register. Then open The Goonies Jackpot King or Eye of Horus Jackpot King and play your spins. Betfair pays free spins winnings as cash. For the bonus 50 spins, opt in on the Promotions page, then deposit and wager £10 on the same games. That second step carries some risk, but we still rate it low. Also, e-wallet deposits do not count, and the spins expire after seven days. You cannot claim this if you have used another Betfair welcome offer before. Always read the full terms on the Betfair Casino website before you deposit.
