Compare Sites Not on GamStop for Online Casino Play
Non GamStop casinos are online gambling sites that operate outside the UK's self-exclusion register. They hold international licences, accept UK players, and often come with bigger welcome packages and fewer restrictions than their UKGC-regulated counterparts. This guide covers the best options, how they compare, and what to look for before you deposit.
Every site we recommend holds a valid licence from a recognised international authority — typically Curaçao or Malta. We verify that games are supplied by audited software providers before any casino makes our list.
We assess the full welcome package — match percentage, free spin count, wagering requirements and time limits — not just the headline figure. A large bonus with punishing terms rarely earns a high rating.
We review the payment methods each site accepts and the processing times on withdrawals. Sites that delay payouts without good reason are marked down, regardless of how attractive their bonus looks.
What GamStop Is — and Why Some Players Look Elsewhere
GamStop is the UK's free self-exclusion service. When someone registers, they are blocked from all online gambling sites that hold a UK Gambling Commission (UKGC) licence for a minimum period of six months, one year or five years depending on what they chose at sign-up. The scheme is designed to help people who feel their gambling has become a problem.
Non GamStop casinos are simply sites that are not part of this scheme. They are licensed by authorities in other jurisdictions — most commonly Curaçao — and are not obliged to check the GamStop register before accepting a player. They are not illegal for UK residents to use, but they do sit outside the consumer protections that come with a UKGC licence, which is worth understanding before you sign up.

Our Top Non GamStop Casinos Reviewed
1. Betmica — Best Overall Non GamStop Casino
Betmica sits at the top of our rankings with a joint-highest editorial score of 9.9. The headline welcome offer — 570% up to £5,700 plus 270 Free Spins — is one of the most competitive we have reviewed among sites not on GamStop, and the percentage match gives smaller depositors meaningful leverage as well as high rollers. The GBP denomination also removes currency conversion risk for UK players.
The site covers slots, live tables, and a sportsbook-style events section, making it more than a pure slots destination. Game supply draws from multiple software providers, so the catalogue feels varied rather than relying on a single studio.
- Strength: GBP-denominated welcome offer reduces conversion costs for UK players
- Strength: Multi-category lobby — slots, table games, live casino and sports events
- Limitation: As a relatively newer brand, its long-term withdrawal track record is still being established — check user forums for current feedback before depositing large sums
2. Kikibet — Highest Free Spin Count in the Top Three
Kikibet earns a 9.8 rating and distinguishes itself with a welcome package that combines a sizeable match bonus — 350% up to £5,555 — with 300 Free Spins, the highest spin count among the GBP-quoted offers we reviewed. For slot-focused players, that combination means meaningful play time from a first deposit without committing the entire opening balance to one game.
The platform carries a broad slots library and supports several popular payment methods, including options that process quickly for UK accounts. Table game coverage is present, though the slot offering is clearly the primary draw.
- Strength: 300 Free Spins is a strong pull for players who favour slots
- Strength: GBP-quoted bonus removes guesswork around the actual sterling value
- Limitation: Table game and live dealer selection is less developed than on some rival sites, so players who split time between slots and tables may find the breadth thinner than expected
3. Betninja — Straightforward Offer, Strong All-Round Score
With a 9.7 editorial rating, Betninja markets itself with a clean, accessible welcome: £1,000 bonus plus 100 Free Spins for all new players. The fixed GBP cap makes it easy to know exactly what you are claiming, which is a useful contrast to percentage-only offers where the real-terms value depends on the deposit amount.
Betninja covers the main game categories — slots, table games and live dealer — and includes sports betting, making it a genuine multi-product destination rather than a single-vertical site. That breadth is useful for players who want flexibility in how they use their balance.
- Strength: Fixed GBP bonus cap makes the offer transparent and easy to plan around
- Strength: Sports betting alongside casino gives players more ways to use the same account
- Limitation: The welcome package is less aggressive by percentage than some rivals, so players who deposit larger amounts will see a proportionally smaller match than at sites offering 500%+ matches
4. WinnerIsland — Reliable Mid-Table Choice
WinnerIsland carries a 9.6 rating. Its welcome offer of up to €1,000 plus 100 Free Spins is quoted in euros, so UK players should account for conversion when estimating the actual sterling value. The site's strength is in its consistency: a well-organised lobby, a mix of game types and a straightforward bonus structure that does not bury the player in conditional small print.
- Strength: Clean, easy-to-navigate interface suits players who find busy casino lobbies overwhelming
- Limitation: Euro denomination means the GBP value of the offer fluctuates with the exchange rate — factor this in before depositing
5. Rivo — Standout Cashback Offer
Rivo's 9.8 rating is partly driven by an unusual feature in its welcome package: alongside a 1000% match up to €10,000 for slots, it includes a 25% cashback element. Cashback is genuinely different from a standard deposit match — it returns a portion of net losses rather than adding to the deposit, which softens downswings during the early play period. For players who prefer loss mitigation over upfront volume, this structure has real practical appeal.
- Strength: Cashback component provides a real safety net that pure match bonuses do not
- Limitation: Euro denomination and the scale of the headline offer (1000%) mean that full terms — particularly wagering requirements — deserve very careful reading before depositing
Understanding the Welcome Offers
The percentages quoted by non GamStop casinos are often much higher than the 100% matches typical of UKGC-licensed sites. That is partly because international operators face fewer marketing restrictions. However, a higher percentage does not automatically mean better value — wagering requirements, game contribution rates, maximum bet rules and withdrawal caps all affect what you actually take home.
Key terms to check for any offer:
- Wagering requirement — how many times you must wager the bonus (and sometimes deposit) before withdrawing. 30x is moderate; 60x or above is high.
- Game contribution — slots typically count 100% towards wagering; table games and live casino often count far less, sometimes 0%.
- Maximum bet while bonus is active — exceeding this limit can void the bonus entirely.
- Time limit — most bonuses expire within 7–30 days of being credited.
- Maximum withdrawal from bonus winnings — some sites cap how much you can withdraw from free spin winnings.
Payment Methods at Non GamStop Casinos
Because these sites operate outside the UKGC framework, they are not bound by certain UK-specific payment restrictions — including the 2020 ban on credit card gambling that applies to UKGC-licensed operators. The methods most commonly supported include:
| Method | Typical Deposit Speed | Typical Withdrawal Speed | Notes |
|---|---|---|---|
| Debit Card (Visa/Mastercard) | Instant | 1–5 business days | Widely accepted; slowest withdrawal option |
| E-wallets (Skrill, Neteller, MuchBetter) | Instant | 24–48 hours | Often the fastest payout route |
| Cryptocurrency (Bitcoin, Ethereum etc.) | 10–60 minutes | Under 1 hour (once approved) | Subject to network congestion; some sites offer crypto bonuses |
| Paysafecard | Instant | Not available for withdrawals | Deposit-only method; useful for budgeting |
| Bank Transfer | 1–3 business days | 3–7 business days | Higher limits but slowest overall |
Individual sites vary. Always check the cashier section of a casino before depositing if a specific payment method matters to you.
What You Can Play at Non GamStop Casinos
The game libraries at international casinos tend to be broader than those at UKGC-licensed sites, partly because they are not subject to the same product restrictions. Here is how the main categories typically break down:
Slots
Slots make up the largest share of any casino lobby. At non GamStop sites you will typically find classic three-reel fruit machines, five-reel video slots with bonus features, Megaways titles (which can carry six-figure win potential), and progressive jackpot games where the prize pool builds across multiple players. Software is supplied by studios including Pragmatic Play, NetEnt, Play'n GO, Microgaming and many others.
Table Games
Blackjack, roulette, baccarat and poker variants are standard across all the sites we reviewed. Many carry multiple versions of each — European Roulette, American Roulette, French Roulette, multi-hand Blackjack, and so on — so experienced table players will find genuine variety rather than a single version of each game.
Live Casino
Live dealer rooms stream real dealers and tables from studio environments in real time. They are typically powered by Evolution, Pragmatic Play Live or similar providers. Common live games include Blackjack, Roulette, Baccarat and game show formats such as Crazy Time and Deal or No Deal Live. Bet limits in live rooms vary considerably — some tables accommodate very low stakes, others are aimed at higher rollers.
Sports Betting
Several sites on our list — including Betninja and Betmica — operate a sportsbook alongside the casino. Football, horse racing, tennis and American sports are the most common markets. Combining casino and sports betting on one account gives players more flexibility in how they use their balance, though the two products usually have separate bonus terms.
Non GamStop Casinos vs UKGC-Licensed Casinos
Both types of site have their place. The differences worth knowing before you choose are practical, not legal.
| Factor | Non GamStop Casino | UKGC-Licensed Casino |
|---|---|---|
| GamStop integration | Not enrolled | Mandatory |
| Regulator | Curaçao, Malta or other international body | UK Gambling Commission |
| Typical welcome offer | Often 200%–1000%+ match | Typically 50%–100% match |
| Credit card deposits | Often permitted | Banned by UKGC since 2020 |
| Player dispute resolution | Via ADR provider or regulator in licensing jurisdiction | Via UKGC-approved ADR bodies |
| Safer gambling tools | Varies by site — check before registering | Mandatory deposit limits, self-exclusion etc. |
| Game availability | Broader in many cases; fewer UK-specific restrictions | Subject to UKGC game design rules |
Licensing and Your Legal Position as a UK Player
Non GamStop casinos are not UKGC-licensed, but using them is not illegal for UK residents. The Gambling Act 2005 does not criminalise players for accessing offshore gambling sites. The regulatory gap is on the operator side: these sites cannot legally advertise to UK residents and are not permitted to hold a UK operating licence while ignoring UKGC conditions.
What this means practically is that the UK consumer protections attached to UKGC-licensed sites — mandatory dispute resolution through approved bodies, the right to reclaim funds in certain scenarios, UKGC-enforced responsible gambling tools — do not automatically apply at non GamStop casinos. Dispute resolution is instead handled through whichever body the site's licence requires, or through the licensing authority directly.
Before registering, confirm:
- Which authority issued the licence and whether that authority has an active complaint process
- What responsible gambling tools the site offers voluntarily (deposit limits, session reminders, self-exclusion)
- Whether the site uses certified random number generation for its games
If you are looking to self-exclude from a non GamStop casino specifically, most reputable international sites offer their own self-exclusion tools within the account settings. For broader support, resources such as GamCare and BeGambleAware operate independently of GamStop and can help regardless of where you have been playing. See our Responsible Gambling page for more detail.
How to Self-Exclude from Non GamStop Casinos
Because these sites are not part of the GamStop network, a GamStop self-exclusion has no effect on them. If you want to stop playing at a particular non GamStop casino, you have three main routes:
- Use the site's own self-exclusion tool — reputable international casinos include a self-exclusion option in account settings or via customer support. This is the quickest direct route.
- Contact customer support directly — request a permanent account closure and ask that it be treated as a responsible gambling exclusion rather than a standard account close (which may be reversible).
- Use third-party blocking software — tools such as Gamban block gambling sites at the device level regardless of whether they are on GamStop. This can be applied alongside a site-level exclusion for additional protection.
Choosing the Right Site for You
The right non GamStop casino depends on what you prioritise. Use the questions below to narrow it down:
- Do you play mainly slots? Look at Kikibet (300 Free Spins) or Rivo (cashback on losses).
- Do you want a large GBP-denominated bonus? Betmica (up to £5,700) and Zombillion (up to £4,000) both quote in sterling.
- Do you want sports betting as well as casino? Betninja combines both under one account.
- Do you prefer a cashback safety net over a headline match bonus? Rivo's 25% cashback element is unusual and worth considering.
- Do you want the largest possible match percentage? Rivo (1000%) and Gambiva (800%) lead on percentage, though both quote in euros.
Whatever you choose, set a deposit limit before you start, read the bonus terms fully, and treat any welcome offer as a bonus rather than guaranteed income. If you have questions about this site or our methodology, visit our About Us page or Contact Us directly.
