31Bets Casino Review UK – Promo Codes & Sister Sites

The welcome package, unpacked

31Bets leads with a matched welcome offer of 100% up to £500 plus a Free Bet, and it’s worth understanding how the maths actually plays out before you deposit. The 100% match doubles your first deposit up to a £500 ceiling, so putting in £250 gives you £500 to play with. The Free Bet element is a nice sweetener on top, though the site keeps the details of how it’s credited fairly light. The catch — and there is one — is the 35x wagering requirement that applies to bonus funds. That’s a mid-table figure by offshore standards: not punishing, but not a walkover either. On a maxed £500 bonus you’d be looking at £17,500 in turnover before withdrawal, so treat the headline number as playing credit rather than cash in hand.

One detail that genuinely helps players here is the absence of the £5 slot stake cap that UK-licensed sites enforce. If you like to run through wagering at a higher stake, or simply prefer bigger spins, that freedom makes clearing the bonus feel less like a grind.

Licensing and the trade-off

31Bets runs on a Curaçao licence, which is what allows it to accept UK players who aren’t on GamStop in the first place. Be clear-eyed about the trade-off: an offshore permit means fewer of the consumer safeguards you’d get under the UKGC — no deposit limit mandates, no GamStop link, and dispute resolution that’s harder to lean on. It’s the price of admission for a non-GamStop casino, and it’s why we score it a solid but not spectacular 7.4 out of 10.

Banking and payouts

Deposits start at just £10 and stretch to a generous £10,000, while withdrawals run from £20 up to £5,000 per transaction. Cashout times are quoted at 24–72 hours, and crypto is where 31Bets is at its quickest. The banking menu is broad: Visa and Mastercard for cards, Skrill and Neteller for e-wallets, and BTC, ETH and USDT for crypto users. KYC is described as low, which suits players who want a quicker onboarding, though it’s another reminder of the lighter-touch regulatory environment.

Games

The library is respectable, with 3,000+ titles drawn from 50+ providers. Slots, table games and live casino are all present, so the core bases are covered, though there’s no sportsbook, bingo, virtual sports or mini-games here — this is a casino-first operation rather than an all-in-one platform.

• Pros: accepts UK players not on GamStop; fast crypto withdrawals; generous welcome package; no £5 slot stake limit.
• Cons: offshore licence with fewer UK safeguards; wagering requirements apply to bonus funds.

A quick word on responsible play: this is an 18+ site, and because it operates outside GamStop there’s no UK self-exclusion safety net to fall back on. Set your own limits and stick to them.

Who it’s for: UK players outside GamStop who want a sizeable matched bonus, higher stakes and speedy crypto cashouts, and who accept the reduced protections of an offshore licence.
