Each ‘How I would use’ note describes the gaming experience I would expect as a returning player, not just on sign-up day.

Not every casino provides existing customer betting offers, which is what makes Sky Casino such a good choice. Sky Casino is an excellent choice for existing customers as it regularly offers promotions for existing players, making it well worth your time to log in every now and again to see the current promotions. The 10x wagering requirement applies to the deposit and bonus combined, so £600 in total stakes is needed before winnings can be withdrawn from the bonus balance, with 30 days to complete it. Grosvenor Casino’s welcome offer is built around a £20 first deposit, which returns a £40 bonus plus 100 free spins on Big Bass Splash.

Here the £20 is simply £20, sat in the balance, ready to withdraw or carry into another game. The 10x cap that came in this January means a £20 return from a standard offer needs £200 staked before you can withdraw it, and most of that gets lost to the house edge on the way through. Betfred’s no wagering rule is worth more than the headline spin count. Time limits and further T&Cs apply. Game and payment method restrictions apply. The casino experience you get at 11pm on a phone is not always the one advertised on the desktop homepage, so each review reflects both.
