Any casino offering wagering requirements of 10x or lower (or better yet, no wagering at all) gets a massive nod of approval from us. This means that while a larger matched bonus or more free spins generally mean a better bonus, that is only true if it comes with reasonable wagering requirements. While most casinos force you to choose between a deposit match or free spins, this offer gives you both. However, the low wagering requirements and the weekly 10% Cashback (credited every Friday) make Duelz a top pick for regular players. The casino offers a unique “adventure” experience, and the Duelz welcome bonus is designed to keep you coming back for a full week. Just remember that if you withdraw your cash before finishing the £20 wagering requirement, you’ll void the offer.
