      21Casino Promotions and Rewards

      We’ve already seen that 21Casino are not shy with the free spins and bonuses for new customers. But what about their loyal base?

      Well, at time of writing, the team were splashing out double loyalty points for playing the Ted Slot game (new from Blueprint in 2017).

      They also seem to know something about their customers – EVERY Monday and Tuesday 21Casino dish out a Hangover Bonus – 21% up to £210 on the first deposit of the day. How’s that for easing you back into another tough week! Usual wagering requirements apply of course.

      The regular weekend Stairway Bonus gives 10% extra on first deposits of the day up to £50, 20% on deposits up to £100, and 30% on deposits up to £500.

      Finally, the smart looking Loyal Royalty program will ensure that every £1 you wager at 21Casino will earn you points which can be exchanged for bonuses.


        Cashier Options

        The modern casino needs to offer a wide choice of cashier options to customers as there are now so many payment systems out there, and everyone has different needs. 21Casino has many options – from credit and debit cards, through Trustly, Giropay and Sofort, to Neteller, Skrill and Wire Transfer.

        There is a 48 hour pending time on all withdrawals before they are processed – which is fairly standard – after which credit and debit card withdrawals may take up to 5 days to appear, and eWallet withdrawals up to 24 hours.
