Duelz Casino review 2026: SuprPlay licence, offers and sister sites

Duelz Casino is operated by SuprPlay Limited, which holds an active remote licence from the Gambling Commission under account 48695, and duelz.com is listed as an active domain on that account. Duelz is therefore a licensed casino for UK players. Below, this Duelz review sets out the register entry and the brands on the same account, then turns to the welcome bonus and cashback terms you will meet on the site.

SuprPlay Limited and account 48695

The register entry for account 48695 names SuprPlay Limited as the licence holder, with casino as its remote activity. There is no betting or bingo activity on the account, so Duelz is a casino brand rather than a sportsbook. When you open an account at duelz.com, your agreement is with SuprPlay Limited: it sets the terms, handles complaints and answers to the Commission. The Duelz footer should repeat the account number; the guide to checking a casino's UK licence shows how to match it against the register in a few steps.

Duelz sister sites under SuprPlay

SuprPlay Limited also runs NYSpins, LosVegas and Voodoo Dreams on the same account. The Duelz sister sites page compares them. Brands on one licence usually share support, the cashier and the shape of their terms, so a rule you find in one set of terms is worth looking for in the others.

The shared account matters most if you want to stop: read whether a SuprPlay exclusion covers all four brands, or use GAMSTOP, which blocks every GB-licensed site at once.

Reading the Duelz welcome bonus and cashback terms

The current Duelz welcome bonus, any cashback, spins or promo code are set out in the operator's own promotion terms, and they change often. Before you accept any offer, look for these significant terms, which must be shown with it:

• the minimum deposit and any payment methods excluded from the offer;
• the wagering multiple, which may not exceed 10 times the bonus amount for offers made from 19 January 2026;
• how long you have to meet the conditions, and when the bonus expires;
• eligible games, the maximum bet while a bonus is active and any cap on winnings;
• for cashback, whether it is paid as cash or as bonus funds with wagering attached.

A single offer may no longer require play across different products. The casino cashback bonuses page explains the difference between cash and bonus cashback, and the wider rules are in UK casino bonus rules in 2026.

Duelz Casino UK cashier and app

Payment methods, withdrawal times and any Duelz Casino app are set out in the operator's cashier and on its site. Some points apply at every GB licensee. You cannot gamble with a credit card, including through an e-wallet funded by one. Age and identity are checked before you can deposit or play, and further checks on funds can follow. A withdrawal cannot be reversed into your balance once requested. Online slots are limited to a £5 stake per spin, or £2 if you are aged 18 to 24.

Keeping control at Duelz

Deposit limits, reality checks and time-outs are set in your account, and as a GB licensee Duelz must honour a GAMSTOP exclusion; the GAMSTOP guide explains the periods on offer. Duelz is for adults only: 18+. Free, confidential support, including the National Gambling Helpline on 0808 8020 133, is on the responsible gambling page.

Duelz review score

The score of 5.6 out of 10 rests mainly on the licence: a single-activity casino account with the domain listed as active. Offer, payment and withdrawal details sit in the operator's terms, which are worth reading before you register.
