We have analysed and compared dozens of UK gambling sites not on GameStop to bring you the 10 best ones.

Top 10 Non-GamStop Casinos Comparison

We have thoroughly analysed dozens of gambling sites not on GamStop and compared their features to bring you the 10 best ones you can start playing at today.

While there is no singular best non-GamStop casino, each has benefits in specific areas of its operation.

How We Rate Casino Sites Not on GamStop

When reviewing non GamStop casinos UK, we pay particular attention to characteristics that relate to their fairness, legitimacy, and responsible gambling features.

Payment option support is also important as it defines which types of players a casino not on GamStop will accept. A detailed breakdown is below:

• Licensing & Regulation: The first step we take is determining which licence the casino without GamStop has. It must be from a proven gambling authority like Malta, Curacao, or Anjouan. Without a valid licence, we do not proceed with the review.
• Payment Methods: Hosting numerous payment options means the online casino not on GamStop suits all sorts of users. Higher scores are given to sites that have all 5 of the main methods in credit cards, e-wallets, bank transfers, cash vouchers, and especially crypto (Bitcoin, Ethereum, etc.).
• Withdrawal Speed: UKGC casinos falter in this category because they have to verify your identity to process your withdrawals. So we want the non-GamStop casino sites we review to do it faster. Up to 24 hours is acceptable for all methods except crypto, which should be processed instantly.
• Customer Support: The customer support team has to be up to any task, and it’s expected that they help users quickly. An inefficient support team can cause delays, and players may leave the casino due to the unresolved issue they’re facing.
• Security Details: How does a casino not on GamStop protect its users well-being and information? We scrutinise as much of the casino’s security systems as possible to determine the extent of its cover. Things like 256-bit SSL encryption are necessary, and casinos without it are vulnerable to unauthorised access.
• Reputation and Players’ Reviews: At the end of the day, you and other UK players all have unique gambling experiences. We take into account the reputation of the casinos not on GamStop and overall player reviews sentiment for a more subjective idea of the site’s quality (as we ourselves are impartial).

Why Do UK Gamblers Choose Casinos Not on GamStop in 2025?

There are numerous reasons why non-GamStop casinos see so many UK gamblers nowadays. The first of which is fewer or no restrictions, thanks to the casinos’ offshore licences. On top of that, they provide game libraries containing thousands of more games than UKGC casinos (e.g. Donbet with 7,750+ titles).

This also means that a casino not on GameStop has more partnerships with respected game providers like Booongo, Play’n GO, and Pragmatic Play.

Other reasons include cryptocurrency support, more accepted payment methods, more generous bonuses (e.g. 300% up to £1,500 at MyStake), no ID verification registration, and more.

Bonuses Available at UK Casinos Not on GamStop

Due to holding international gambling licences that are detached from the UKGC, casinos not on GamStop have a larger spread of bonuses that are also more generous than what UKGC-licensed sites offer.

• Welcome Bonuses: The welcome offer is arguably the most rewarding type of bonus, often coming with a combo of deposit matching and free spins (e.g. Velobet’s 330% up to £2000 + 70 FS). To claim them, you have to register an account, deposit the minimum amount, and satisfy any bonus terms and conditions.
• No Deposit Bonuses: These small rewards at casinos not on GamStop are given to players upon registration and don’t require a deposit to claim. As such, the amounts are smaller than with other promos, and are usually in the form of a £5 bankroll boost or some free spins. Get 25 FS at MyStake with our exclusive promo code “NGB”.
• Free Spins: Perfect for slot game enjoyers, free spins are a way to play slot games without wagering your own money. Usually, they are given as part of welcome bonuses but may also be part of VIP programs or given out as rewards for tournament participation.
• Reload Bonuses: As a way to help you out with a little extra financial boost, non GamStop casinos provide reload bonuses that activate for each deposit you make. For example, you can claim a weekly reload casino bonus of 100% up to £500 at NationalBet.
• VIP Programs: Players who frequently partake in games at casinos not on GamStop are enticed to continue playing via VIP Programs. You progress through the levels, with each new level giving you bigger and better rewards. Donbet’s VIP program gives you 1,000 FS, 10% rakeback, and 15% weekly cashback at the highest level.
• Cashback: If you have an active cashback promotion, you’ll receive a specific percentage of every wager you make, regardless of the outcome. Having a 10% cashback and making 10 losing wagers essentially means you get every 11th wager ‘free’.

Hidden Bonus Conditions to Watch Out for at Non-GamStop Casinos

Although finding massive bonuses at non GamStop casinos is great, there are often numerous terms and conditions you need to fulfil to claim them.

For instance, CasinoJoy’s first deposit bonus is 200% up to £1,000 + 100 free spins. The wagering requirement is x30, which is lower than average (x35) for this sort of offer. Additionally, you can only use your FS in the Super Sweets slot game by BetSoft.

Always check the bonus conditions thoroughly to see if claiming them is feasible for you.

Best Games Offered by Non-GamStop Casinos

Every non GamStop casino has a dedicated gambling entertainment section with multiple categories of games, ranging from traditional slots to instant/crash games. A rich variety of games from reputable software providers means players of all interests can play their favourite type of casino game.

Slots

When it comes to slots not on GamStop, there’re thousands of possibilities. Donbet, for example, has 7,755 casino games, 5,000+ of which are slots.

Slot games at UK online casinos not on GamStop differ in themes, number of reels & paylines, jackpots, and other bonuses like multipliers. They’re the most popular casino games due to their ease of use and high-payout potential.

Table Games

Players that prefer a strategic approach as opposed to a purely luck-based one will enjoy their time at non GamStop casino sites due to the vast support for table games.

Donbet, Velobet, and othe casinos have virtual adaptations of renowned card games like Poker, Baccarat, Blackjack, but also versions of Roulette, Sic Bo, Dragon Tiger, and many others. Most table games have their live dealer variants as well.

Live Casino Games

Live casino or live dealer games will have you participate in an online lobby with the ability to interact with the dealer him/herself. There’s also a relatively short ‘grace’ period between rounds, allowing you to think about your strategy going forward.

Commonly, the best non GamStop casinos will feature a live dealer library of a hundred or so games, with the exception of CasinoJoy that has more than 830.

Instant Win Games

When you want short rounds, instant payouts, and simple rules, instant or crash games are your best bet. These are found at most non GamStop casinos UK, such is the case with MyStake which hosts 25 of these games. The titles that UK players play the most include HiLo, Keno, Plinko, and Thimbles.

Video Poker

Video poker is essentially five-card draw poker but played as a slot game. You draw five cards, and depending on what you get (three of a kind, royal flush, etc.), you’ll receive a specific number of coins.

There is no strategy involved in your draw, meaning it’s more luck-based than Texas Hold’Em and other poker variations where you match your hand with the dealer’s.

Payment Options at Non-GamStop Online Casinos

Due to less strict financial regulations and the crypto support from international gambling authorities, non-GamStop casinos host a wider range of payment methods than UKGC ones.

Credit and Debit Cards

Using cards is primarily done for convenience as it’s the most popular payment method. Card transactions are usually processed within 24 hours by UK gambling sites not on GameStop and almost all accept them.

Cryptocurrencies

One of the biggest benefits of casino sites not on GamStop is their cryptocurrency acceptance. This payment methods is fully anonymous, has instant withdrawals, and zero fees. The most common coins are Bitcoin, Ethereum, and Litecoin.

eWallets

E-wallets are another popular choice at non-GamStop gambling sites due to ease of use and no identifiable personal information. Still, they can be slow to process (up to 48 hours) and may incur higher-than-average fees.

Bank Transfers

If you’re looking for a secure and reliable transaction option at casinos not on GamStop, bank transfers are great. On the other hand, they are slow to clear (up to 5 days), are connected to your bank account, and may get declined by your bank.

Prepaid Cards

Prepaid cards have slowly become widespread at the best non GamStop casinos thanks to fast processing and user anonymity. They’re best used for deposits or as a way to limit bankroll expansion (since they have a fixed cash amount).

Player Experience with UK Casinos Not on GamStop

1. Brian Stocklin: After some disappointing experiences at UKGC casinos, I gave gambling sites not on GamStop a chance. I was thoroughly impressed since I got a massive bonus for my first deposit and managed to win a few wagers. Went to withdraw my winnings with Ethereum and they were processed in 3 minutes! Overall, I’m very happy so far with how it’s been going.

2. Emma Laysworth: I like to gamble a few quid each Friday so wanted to check these casinos. I’ve had a good time but had an issue where I wasn’t getting the rewards from the VIP program. Reached out to support to see what’s up and it turns out I just had to tell them about the rewards so they could initiate the system. They fixed it for me real fast!

Responsible Gambling Tools Available at Non-GamStop Gambling Sites

Even though non-GamStop sites aren’t a part of the UKGC mandatory self-exclusion scheme, they still offer various responsible gambling tools to players.

How to Identify Fraudulent Non-GamStop Casinos

Although most non GamStop gambling sites are safe to play at, you should still keep an eye out for certain characteristics that fraudulent casinos may exhibit.

You can also safely use any of the non GamStop sites reviewed in this guide.

• Lack of Licensing: This is the first and most important step in determining whether or not a non-GamStop casino is legit or not. If it doesn’t have one of the international licences (Curacao, Malta, etc.), avoid it at all costs.
• Unclear Terms and Conditions: Fraudulent casino sites will not go through the tedious process of creating clear and concise Terms & Conditions of use. If it doesn’t exist or has confusing, contradictory, or incorrect information, the casino may be risky to use.
• Poor or Non-Existent Customer Support: Whenever something goes wrong on a casino without GamStop, the customer support team is there to help. The lack of a proper support team or effective communication channels may be evidence that the gambling site is fraudulent.
• Unrealistic Bonuses: The proverb ‘If it’s too good to be true, it probably is’ definitely comes in handy here. Finding an impossibly large bonus with incredibly easy terms for claiming is often a red flag and presents a risk related to your finances.
• Negative Reviews or Complaints: While the existence of constructive criticism is helpful (letting the non-GamStop casino know it can do certain things better), an overwhelming amount of negative player experiences can point toward a deeper, more dangerous issue.
• Unusual or Suspicious Software Providers: Games that aren’t made by respected and established software providers can be fraudulent and give the hosting casino a big edge over the player. This can lead to severe losses. Look for names like Pragmatic Play, Booongo, BGaming, and others to avoid this.
