Diamond 7 Casino review 2026: licence holder and sister sites

Is Diamond 7 Casino a licensed site? Yes: the Gambling Commission register lists diamond7casino.com as an active domain under account 52894, held by White Hat Gaming Limited. This Diamond 7 Casino review sets out what that licence covers, which other brands share it and what any GB player can rely on before reading the operator's own offer terms.

Diamond 7 Casino review: the White Hat Gaming licence

White Hat Gaming Limited holds active remote licences on account 52894 covering casino, bingo, gambling software and general betting on real and virtual events. Diamond 7 Casino is one of the brands it runs on its own platform. The licence holder, not the brand name, is the business you contract with, the one that answers your complaints and the one the Commission supervises. Its footer should show the account number, and you can match that number to the domain on the public register.

Diamond 7 Casino sister sites

Brands linked to the same licence holder include 21 Prive, G'day Casino, Hello Casino, Mainstage Bingo, Skol Casino, Slotnite, 21 Casino, Casilando, Casimba, Dream Vegas, Jackpot Village, PlayGrand, Playzee, Slot Planet and Temple Nile. Sister sites on one platform tend to share the cashier, the support team and the structure of their terms. The Hello Casino review and the Skol Casino review cover two of them.

Shared ownership has a practical side for self-exclusion. An exclusion you set with White Hat Gaming may reach every brand on the account or only one, depending on its terms. GAMSTOP is wider: it applies to every GB-licensed site at once.

Diamond 7 Casino bonus, free spins and no deposit offers

The current Diamond 7 Casino bonus, any spins offer, any no deposit bonus and any promo code are set out in the operator's own promotion terms, and those change often. Whatever the offer, GB rules set the frame:

• Wagering may not exceed 10 times the bonus amount, for offers made from 19 January 2026.
• A single offer may not require play across different products, such as betting and casino together.
• Significant terms, including minimum deposit, expiry, eligible games, maximum bet and any cap on winnings, must be shown with the offer.
• Spins that need a deposit or a stake should not be advertised as free.

The no deposit bonuses page explains how those offers usually work and why caps on winnings matter.

Cashier rules that apply anyway

Payment methods, withdrawal times and any Diamond 7 Casino app are shown in the operator's cashier and on its site, so check them there. Some rules are fixed for every GB licensee. Credit cards cannot be used for gambling, including through e-wallets funded by a credit card. Age and identity are verified before you can deposit or play. A withdrawal cannot be reversed once you have asked for it. Online slots are capped at £5 per spin, or £2 if you are aged 18 to 24.

GAMSTOP and account limits

Every GB-licensed casino must take part in GAMSTOP, which runs for 6 months, 1 year or 5 years and stays in place after that until you ask for it to be lifted. Deposit limits and time-outs are set in the account; the deposit limits guide explains each tool. Diamond 7 Casino is for over-18s only. If gambling is causing worry, the responsible gambling page lists free, confidential help.

Where Diamond 7 Casino stands

Diamond 7 Casino scores 5.8 out of 10. The score reflects the active licence and the active domain listing; offer and payment details are for the operator's terms to set, so read them before you register.
