Claiming it is quite simple: just opt-in and place a wager of minimum £5, while the max free bet you’ll get can exceed £20. The offer applies to all 5+ accumulators on all markets and on all sports, including pre-live and in-play.
Remember, your accumulator can contain only one losing leg, or else you won’t be able to claim your refund. A single customer can get only one free bet per day. Once you receive your free bet, you’ll have seven days to use or otherwise it will expire.
