Launched in 2018 by SuprPlay Limited, Duelz Casino is a mobile-first gaming site that blends traditional online casino gaming with innovative player-versus-player (PvP) duels, where players compete in slot battles to earn rewards. In its first year of operation, the casino picked up an EGR Innovation Award, and it holds licences from three of the most respected regulators in the world, the UK Gambling Commission, the Malta Gaming Authority, and the Swedish Gambling Authority.
With over 2,000 casino games and collaborations with top software developers including Pragmatic Play, NetEnt, Play'n GO, Big Time Gaming, and Evolution Gaming, Duelz has built a reputation as something genuinely different in a crowded UK market. But it's not just the PvP format that sets it apart, it's how the casino treats players when the week hasn't gone their way.
Every Friday at 10:00 UTC, Duelz credits 5% of the previous week's net spend directly back into player accounts as real money. The calculation is straightforward: net spend equals bets placed, minus winnings, minus any rewards already received.
The Duelz weekly cashback window runs from Friday 00:00 to Thursday 23:59 UTC each week, with a minimum return of £0.10. All games on the platform are included.
What makes this stand out is the absence of wagering requirements. The money lands in your account and you can use it however you choose, no playthrough conditions, no strings, no small print designed to make the value disappear before you can access it.
Wagering requirements are one of the most common frustrations among UK casino players. Bonus funds tied to 30x or 40x playthrough conditions can feel more like a treadmill than a reward, and many players find the value evaporates long before the conditions are met.
Duelz's approach is different. The 5% cashback is credited as real money, which means it behaves exactly like a cash balance, withdrawable, usable on any game, and not subject to hoops. For players who gamble regularly across the week, this functions as a genuine financial safety net rather than a marketing tool dressed up as one.
It also rewards consistency. Whether you've had a good week or a losing one, knowing that a proportion of your net spend is coming back every Friday adds a layer of predictability to your bankroll management. For players who take their casino play seriously, that matters.
The cashback offer doesn't sit in isolation. Duelz runs daily cash tournaments with nearly £1,500 in prizes, and its promotions page features cashback, free spins, and tournaments that suit different playstyles, offering fresh ways to boost your balance beyond the welcome bonus.
Rather than a traditional VIP scheme with tiers or invite-only perks, Duelz focuses on a gamified loyalty system where every player automatically earns rewards through gameplay, particularly by participating in duels and competitions. The weekly cashback sits within that philosophy, a standing, automatic reward that doesn't require players to opt in, jump through verification hoops, or keep track of a separate loyalty points balance.
Duelz is also fully compliant with UK regulations, including the 2025 safer gambling measures, and has implemented the maximum stake limits of £5 per spin for players aged 25 and over, and £2 per spin for those aged 18–24, across its slot games.
For UK players who want a casino that gives something back without making them work for it, the Duelz weekly cashback is one of the more player-friendly standing offers on the market right now. Real money, no wagering, every Friday, it's a simple proposition, and in an industry where bonus terms can be exhausting to decode, simple is often genuinely valuable.

Most of my career was spent in teaching including at one of the UK’s top private schools. I left London in 2000 and set up home in Wales raising four beautiful children. I enrolled at University where I studied Photography and film and gained a Degree and subsequently a Masters Degree. In 2014 I helped launch a new local newspaper and managed to get front and back page as well as 6 filler pages on a weekly basis. I saw that journalism was changing and was a pioneer of hyperlocal news in Wales. In 2017 I started one of the first 24/7 free independent news sites for Wales. Having taken that to a successful business model I was keen for a new challenge. Joining the company is exciting for me especially as it is a new role in Europe. I am keen to establish myself and help others to do the same.
