Best Non Gamstop Casinos for 2025 – List of Top Casino Sites Not on Gamstop UK

6 months ago 42

Not all non-Gamstop casinos are built the same. Sure, they all offer generous bonuses – but not all of them are capable of paying out your winnings quickly and without hassle.

We turned a lot of stones to find the best casinos not on GamStop for UK players. These are secure, legit, action-packed non-UK casino sites that take all necessary measures to provide high-level entertainment while offering high player protection and fast payouts.

Leading the way is NationalBet, a rather fresh casino site that stands out with a great variety of games, quick payout processing, reliable support, and generous bonuses.

Let’s take a closer look at our full list.

Detailed Reviews of the UK’s Top Non-GamStop Casinos

Even a list of five non-GamStop online casinos can create dilemmas, which is why we went a step further and reviewed each one individually, highlighting their strengths and weaknesses so that you can make an educated choice about what matters to you the most.

1. NationalBet: Overall Best Casino Not on Gamstop in the UK

AD 4nXfJD6X5dqS0u U7CZX7n1jJjVH eoiNn8I5prNthLDP8W LqQJn7uSf4JfVn6fhJ 2ystyCG8tb kAt iUO0tqQJJAuQODjgj2bPPK5xCr

Pros:

  • Mixed live casino lobby
  • Fair games from top providers (Pragmatic Play)
  • Filter slots based on risk
  • Complete Missions to earn rewards
  • Weekly Cashback
  • 30 days to complete rollover

Cons:

  • No loyalty programme
  • No mobile app

NationalBet is our pick as one of the best non GamStop casinos from almost every aspect: game selection and quality, fairness, security, bonuses, and banking.

What we liked:

NationalBet Casino got the #1 spot from our team as the best non GamStop casino for its weekly cash and reload promotions, the cashback deal, and mixed selection of live poker, blackjack, roulette, and baccarat. 

Additionally, it supports crypto and fiat currencies and the minimum deposit of £20 is quite low for bonuses and base play. The bonus terms are fair in terms of maximum bets and validity. You have 30 days, which is plenty, to complete all wagering requirements and claim any winnings. 

There are over 1,000 slots, table games, jackpot games, and Mini Games. We liked the Volatility filter, which allows you to select games based on their risk level.

What we didn’t like:

You must register and open an account to gain full access to all information about the casino. 

For instance, you can’t see the withdrawal limits unless you are a registered member. Another thing we like to see NationalBet improve in the future is adding a loyalty or VIP programme to reward the most active users. 

NationalBet Casino Breakdown:

FeatureEditor’s NotesRating
Casino GamesGames from NetEnt, Pragmatic Play, and Novomatic ensure top quality and fairness, but a larger game catalogue is needed for more gaming diversity. ★★★★☆
Welcome BonusA £20 minimum deposit, 30 days to meet rollover, and 200 welcome free spins make the Nationalbet welcome package attractive to any UK player.★★★★★
Payment MethodsNationalBet accepts credit and debit cards, crypto, and MiFinity for deposits and withdrawals. Payout processing, meanwhile, is usually done within 1 hour.★★★★★

If NationalBet Casino’s managers added a loyalty rewards system, even without having progressive jackpots, it would make it not only among the best casinos not on GamStop but overall one of the best casino sites we’ve tested. Although the casino software is optimised for mobile gaming, we’d like to see a native mobile app released down the road.

2. Freshbet: Best Non Gamstop UK Casino for Slots

AD 4nXc 0OLmZAJiBucGD82ubnhy

Pros:

  • 5,000 online slots
  • VIP Club
  • Loyalty bonus
  • 30-day bonus validity
  • Different responsible gaming features

Cons:

  • No free spins welcome bonus
  • £5 max welcome bonus bet

There is no UK online casino in our list that is not suitable for slots, but FreshBet Casino beats the competition with a large collection of classic and video slots. And that’s just part of what makes it one of the best GamStop-free casinos.

What we liked:

With more than 5,000 slots, Freshbet is the top non GamStop casino for playing slots. Stay active long enough and you can earn VIP benefits, alongside a 10% Loyalty Bonus. 

The live casino lobby consists of over 60 blackjack, roulette, poker, and baccarat tables, including a few game shows. The 30-day bonus validity gives you enough time to complete the relatively low 30x bonus wagering requirements. 

FreshBet also offers 24/7 support and you can set account limits or activate a time-out period. 

What we didn’t like:

Despite our decision to rank Freshbet among the best casino sites not on GamStop for slots, we were disappointed that the welcome package did not include free spins. The maximum bonus bet of £5 also seemed low. 

FreshBet Casino Breakdown:

FeatureEditor’s NotesRating
Casino GamesOver 5,000 slots, including over 130 jackpot slots and dozens of table games, deservingly earn Freshbet a top rating for gaming options.★★★★★
Welcome BonusThe welcome bonus terms are fair but the lack of free spins led us to take away a point. ★★★★☆
Payment MethodsFast deposits and payouts with crypto, no internal fees, and reasonable transfer limits deserve a top rating for banking.★★★★★

We were close to giving FreshBet the top spot had it not been such a great casino for slots. And it’s not merely the number of slots that earned it that rating, but the slot navigation and classification (Bonus Buy, Jackpots, Classic slots, and Megaways). 

However, to be a perfect slot casino, Freshbet  should roll out more free spins bonuses to improve the experience further.

3. Rich Prize: Most Generous Bonuses

AD 4nXc a2MkmH3dJtQZLivvl5X29R1KVr0X8ps7ghtIJ dLf0yIQHx5kTz3iF L4k

Pros:

  • iOS and Android mobile applications
  • Loyalty programme
  • Casino tournaments
  • Mixed game variety
  • Various regular casino bonuses

Cons:

  • 7-day bonus validity
  • Max. bonus win is 5x bonus amount

Loyalty benefits, tournaments, weekly deals, crypto bonuses, and cashback – Rich Prize will shower you with rewards if you play actively.

What we liked:

Rich Prize Casino has partnered with some of the best game providers in the business to offer premium-quality slots and table games. NetEnt, Play’n GO, Betsoft, Playtech and Quickspin are a few of the providers that supply Rich Prize with slots and table games. 

iOS and Android apps make the mobile experience a whole lot easier. The main highlight of Rich Prize Casino is its bonus menu. 

Apart from free spins and cash deals on your first 4 deposits, you can look into a 15% weekly cashback deal, a crypto cashback bonus, bonus spins on your first crypto deposit, and weekly and monthly rakeback. And that’s without counting the options to collect rewards and bonuses through tournaments and the Rich Prize Loyalty programme. 

What we didn’t like:

The bonus wagering requirements are not that high (30x), but the duration of the bonus is low, with only 7 days to wager your bonus through. Also, if you hit a high-paying combination with a bonus, you cannot collect more than 5 times your bonus amount. So, if you claim a £50 bonus, £250 is the maximum you can win. 

Rich Prize Casino Breakdown:

FeatureEditor’s NotesRating
Casino GamesMore than 7,000 games – slots, live games, dice games, jackpots – from leading studios get Rich Prize the highest rating for games.★★★★★
Welcome BonusWith 675% up to £5,000 on 4 deposits and 150 free spins, this is one of the best welcome deals in our guide, although the 7-day validity may not be enough for some players.★★★★☆
Payment MethodsBanking at Rich Prize casino is easy with speedy, fee-free withdrawals (within 48 hours on average at most), low deposit limits (£10), and crypto and fiat payments. ★★★★★

Regarding promotions and game content, Rich Prize is high on our list of casinos not registered with GamStop. However, when claiming a bonus, you have limited time (7 days) to complete the bonus wagering. 

4. GoldenBet: Top Non Gamstop Casino for Live Dealer Games

AD 4nXf nDWu1HOzVey F2vEmHaDHmq1 sZYlN WUHpq6d5WrSSUK8iOswOUJnrTpf6q r5AX4U5 Dv99gl2zOXYpAiy8gM 5WgEZc2WWqlDrpBrLtC5hyJHH9OzC2De 9U dfWK3 ROOw?key=ds5ij72smep2PaD92Aju7aXc

Pros:

  • Hundreds of popular slots
  • Excellent mobile experience
  • Up to £500 cashback
  • 60+ live dealer games
  • 130+ jackpot games

Cons:

  • 45x bonus wagering
  • Limited selection of bonuses

GoldenBet Casino’s partnership with providers like Platipus Live, EGT, and LuckyStreak gives it access to top live casino games from these and more providers. But slot fans have equally as many options for gaming, with a total collection exceeding 3,000 titles.

What we liked:

We’ll start first with the live casino lobby, which offers a collection of roulette, baccarat, poker, and blackjack variants like VIP Auto Roulette, VIP Blackjack, and Dragon Tiger. With a few game shows added to the mix, like Fortune Wheel, GoldenBet belongs to the group of top casinos not on GamStop for live casino games.

There are also 3,000 slots, all optimized for iOS and Android systems. Popular categories like Megaways, Bonus Buy, Classic slots, and Jackpot Games create a diverse blend of slot games. We liked the Thursday and Friday free spins bonuses and the 10% cashback up to £500.

What we didn’t like:

GoldenBet Casino should expand its bonus menu for regular players. Except for the Thursday and Friday spins and cashback, there are no regular deals. Another thing we didn’t like is the 45x bonus wagering requirements, which also apply to the cashback deal.

GoldenBet Casino Breakdown:

FeatureEditor’s NotesRating
Casino GamesGoldenBet offers over 3,000 slots, (live) table games, and more than 130 jackpots from leading developers like Thunderspin, Playson, and Relax Gaming.★★★★★
Welcome BonusUp to £1,500 on signup with a £20 minimum deposit is enough to get anyone started, but the lack of welcome free spins made us deduct a point.★★★★☆
Payment MethodsThe £20 minimum deposit and withdrawal limit will be agreeable to any payer, but GoldenBet should consider adding more banking options.★★★★☆

The game quality at GoldenBet is certified and we liked the Thursday and Friday free spins, but the wagering requirements for bonuses should be lowered to at least 35x from the current 45x, which also applies to the cashback deal. Overall, it’s one of the best casinos not on GamStop for live dealers and slots with fair bonus terms (except for the wagering).

5. Donbet: Best Casino Not on Gamstop UK for Jackpots

AD 4nXeFbqZrEg TY kqMOrYw5v Cy5GUjL4iol96PngBSKe538vMPLzGuzbXTTJGHXOelnpbcPHHP6aWXV2LjEXlEcinIrMKIsN7UxMxkokGFrBnQBVXwEWBXJA QUQbQDSBKTsifm WA?key=ds5ij72smep2PaD92Aju7aXc

Pros:

  • Low wagering requirements
  • Daily, weekly, and monthly tournaments
  • 160+ jackpot games
  • First-class games from over 90 providers
  • 6,500+ games

Cons:

  • The website can be slow to load
  • Only 3 live poker games
  • Bonus rollover on cashback

Winning a jackpot-sized prize is a long shot, but you can’t hope to win if you don’t play, and DonBet feeds your hope with dozens of jackpot tiles. Cash and free spins promotions are always at hand, but mind their terms – they can be sticky.

What we liked:

Spinomenal, Wazdan, and Playson are just three of many industry-leading game providers that equip DonBet’s jackpot game section. Overall, we counted over 160 jackpot titles, with more than 6,500 games in total. 

Looking at the Promotions page, we liked the crypto deposit bonus of 170% up to £1,000. There is also a VIP programme and a special welcome bonus for DonBet’s Mini Games. The daily, weekly, and monthly casino tournaments are always there if you feel competitive and want to earn extra prizes. 

What we didn’t like:

DonBet’s website is mobile optimized but at times it can be slow to load. This was especially true when we tried opening multiple games in a row to test the site functionality. 

Also, if you’re here for live poker, this may not be the casino for you as it only has 3 live poker games. Another thing is that while the VIP programme is great, the cash-to-point rate is £50 for 1 point, and you need between 1,000 and 200,000 points to reach the levels that make the VIP system pay off.

DonBet Casino Breakdown:

FeatureEditor’s NotesRating
Casino GamesTop-of-the-line gaming software from 90+ providers, including Playson, Play’n GO, Quickspin, and BGaming makes DonBet one of the most versatile non UK casinos on this list.★★★★☆
Welcome BonusA solid welcome package of 150% up to £750 and 50 free spins, and 30 days to complete the rollover, but a limited maximum bet of just £5.★★★★☆
Payment MethodsE-wallets, bank cards, and crypto, starting from an average minimum deposit of £20, allow for speedy and secure money transfers (deposits and withdrawals).★★★★★

It’s not just the over 160 jackpot games that made us rank DonBet in our list of top 5 non GamStop casino sites. The over 6,500 premium slots and table games, the exclusive VIP programme, existing casino tournaments, and fast payouts with standard payment methods and crypto all contributed to our final decision. 

What is GamStop?

GamStop is a self-exclusion system. Its main purpose is to restrict gambling of any kind with casinos and bookmakers licensed in the UK. 

If you register with GamStop, you can set a minimum exclusion period of 6 months and up to 5 years. The programme will prohibit access to any accounts and UK-licensed casinos and cancel all email subscriptions that deliver bonuses and other promotional material.

The thing is, once your expiration period ends, GamStop won’t notify you that it has expired. If you don’t manually cancel your membership, GamStop may automatically extend it to 7 more years. 

You can see how players can remain stuck with the program and may seek non GamStop casino sites and bookmakers. 

How We Rank and Review UK Online Casinos Not on GamStop

We rank UK casino sites not on GamStop against a list of established criteria and standards. Based on the following aspects, we determine the casino’s safety and user experience. 

Safety

First, the connection to the site must be secured. SSL and other advanced encryption technologies must be set in place to offer a secure connection between you and the casino and the secure transfer of all data. The casino’s own privacy and security policy must be transparent and efficient, including anti-fraud measures that protect registered members. 

Casino Games

The games are the centrepiece of the entertainment aspect of the casino. Every player has preferences – and diversity in games is an important factor. We examine the slot variety based on betting limits, RTP, volatility, and game providers. We assign online casinos with different slot categories like jackpots, Megaways, and Bonus Buy more points. 

We check the choice of live games, instant games, and card and table games and ensure they come from software providers with proven records of casino software development. 

Bonuses & Terms

Bonuses are like the gift shop of the online casino lobby, and like a gift shop, you have to pay to claim and use the bonus. A minimum deposit is required for every bonus and we select only those UK online casinos not on GamStop that have acceptable minimum deposits, bonus validity periods, and wagering requirements.

The wagering requirements are never easy to complete, but you should only get a bonus if you plan on playing for an extended period of up to 5 or more days. Usually, bonuses are valid for up to 5 days before they expire. You must also mind the maximum bet limits and restricted games. 

Payment Methods and Payout Speed

Deposits through bank cards, e-wallets or crypto must be hassle-free and instant. The casino should not repeatedly ask for proof of identity when you deposit, although it may be required at some casinos when making a withdrawal.

If the payout speed ranges between 1-3 days for Visa, and MasterCard, or up to 7 days with Bank Transfer, we would consider it an appropriate timeframe. Crypto payments shouldn’t take more than 24 at most, but deposits and withdrawals are usually much faster. 

Mobile Experience

A casino’s mobile compatibility goes through several phases of testing on smartphones and tablets. We check the website compatibility on iOS and Android and several popular browsers like Chrome, Mozilla, and Safari. We take into account any performance issues to shape our opinion of the mobile experience.

We used the same ranking criteria to evaluate the top Australian online casinos as well.

How to Find Good Casino Sites Not on GamStop

If you’re wondering how to quickly identify good casinos not on GamStop, the below pointers can be of help. 

  • Legitimacy – A legitimate casino is run by an incorporated company and holds a license. Scroll to the bottom of the website to look for the license details or contact customer support and ask around about the casino’s credentials.
  • Certified games – Reputable game providers offer certified and tested games. The software of the games has gone through multiple tests to guarantee fair results. Trusted game providers, like Play’n GO, Quickspin, Novomatic, and NetEnt are signs of a trusted casino.
  • Bonuses – Don’t rush to get a bonus before you’ve read its terms. If you think you can meet the wagering requirements within the given period, go for it. 
  • Responsible gambling tools – Take things slowly and set your limits from the start. All non GamStop casino sites allow deposit, loss, and/or wager limits. You should also pick a casino with an internal self-exclusion scheme and an option to take a temporary break.

Types of Real Money Games at Non UK Casinos

We can separate casino games into several categories and subcategories for better orientation when browsing.

Slots

Classic 3-reel slots, and multi-line slots like Megaways, jackpots, and bonus buy are the main sub-categories of slots at non GamStop casino sites in the UK. When choosing a slot, we advise you to do your research and focus on the game’s features, RTP, volatility, special symbols, maximum win, and betting limits. 

Pro Tip: When you claim bonus spins, you can use them only on select slot games outlined in the bonus description. You usually cannot play any slot you like when using free spins.

Table & Card Games

RNG or with a live dealer, everyone has a favourite table game. Blackjack, poker, roulette, baccarat, and dice games are often part of the table game lobby. We advise you to avoid playing table games if you have an active bonus due to the low wagering contribution, or no contribution at all.

Pro Tip: There are dozens of variants of roulette, blackjack, and baccarat. While the rules, RTP, and odds are comparable, some variants may have higher betting limits or special rules.

Jackpot Games

Dozens, if not hundreds of table games can form a network of progressive jackpots. Every bet that’s wagered in those games increases the jackpot until someone eventually wins it. Many non-UK casinos have a separate category for jackpot games. It’s important to know that these slots have fixed, rather than progressive jackpot prizes.

Pro Tip: Slots are the only game category that contributes 100% of bets when you wager a bonus. However, jackpot slots are almost always excluded from bonus play, unless otherwise specified. 

Megaways

Megaways are an exclusive sub-category of slots, and one of the most played types of online slots. Usually offering 4 or more reels and between 3 and 7 rows. Special symbols, stacked wilds, and thousands of possible symbol combinations on the reels make them a hugely popular class of slots.

Pro Tip: A lot of Megaways slots, like Wolf Power Megaways or Aztec Magic Megaways have an option to manually buy or trigger a bonus free spins or respins round. We advise you to use this feature every once in a while as it can connect with big wins. But don’t overpay if it seems too much.

What to Know About Bonuses at Non-GamStop UK Casino Sites

Casino bonuses at non-GamStop UK casino sites have a user manual with rules and terms that you must comply with. The terms are similar for all types of bonuses. 

Types of Bonuses

The three bonus categories listed below include all other promotions, which is why we think they are the essential categories based on which you can recognise all other bonus types.

  • Welcome bonuses – Cash bonuses on your 1st, 2nd, 3rd, or 4th deposit between 50% and 150% are common for welcome deals. Free spins on two or more of the deposit bonuses can be included.
  • Crypto bonuses – We’ve seen many online casinos not on GamStop with welcome or regular bonuses exclusive to crypto depositors. The offers are usually bigger, but other than that, the terms of use are comparable to regular bonuses.
  • Regular promotions – Whether crypto or fiat transfers, you will always be eligible for weekly deposit bonuses, free spins, or even cashback on your losses. 

Wagering Requirements

Your bonus (and deposit) are subject to wagering requirements running from 30 to 50 times. This is the difficult part of a bonus. Our advice would be to see if you have the budget to meet the wagering requirements and carefully think it through if you can make the bonus pay off. 

Other Bonus Terms

Keep an eye on these additional conditions that are part of almost every online casino bonus, with some exceptions like VIP rewards and some cashback deals.

  • Game contribution – Slots are the only game category with 100% game contribution. Check the bonus descriptions about possible restrictions on some slots.
  • Validity – In most cases you have 30 days, often fewer, to complete the bonus wagering requirements. Free spins may expire even faster. 
  • Maximum cashout – This is the maximum you can win with your bonus. The amount is specified within the description of every casino bonus.

Guide to Payment Methods at Casinos Not on Gamstop

We can identify 4 main payment categories at UK casino sites that are not part of the GamStop System.

  • Credit/debit cards – Fast deposits, acceptable payout speed, and solid transfer limits make Visa, MasterCard, and Maestro (where accepted) trusted banking options.
  • Prepaid methods – Prepaid deposit methods like Paysafecard are secure, private, and fast options for depositing. You cannot withdraw using prepaid methods.
  • E-Wallets – Money wallets like Skrill, PayPal, and Neteller, provide privacy and great money-transfer speed, but you should expect fees. 
  • Cryptocurrency – The fees you pay on the blockchain to convert crypto to fiat or for processing transactions are worth it for the speed and security cryptocurrencies like Bitcoin, Dogecoin, and Litecoin offer.

Tips for Responsible Gambling

Non-GamStop operators in the UK care for players and allow them to set limits on their gaming activities. You can also take steps on your own to ensure you play within your boundaries.

  • Create a budget  – Create a spending budget just for your gaming sessions from the start. 
  • Don’t chase losses – You’ve lost. So what? No need to express anger or irritation and gamble based on those feelings to make up for lost bets.
  • Take a break – If you can’t control your anger, control your actions. See if you can arrange for a temporary time out or exclusion from all gaming activities and return with a cool head.  
  • Enjoy your time – If you take a break and plan to return, do it on your own terms but when you know you want to play for fun and not to chase profits.
