And, for your efforts, you will be able to claim the 400% up to £2,000 + 100 Free Spins welcome bonus (£20 min deposit, x50 wager requirement). Also, the code for activating this bonus is LION1. Other bonuses include the 200% up to £1,000 + 50 FS 2nd deposit boost (code: LION02), and three other rewards for your 3rd, 4th, and 5th deposits (codes LION3, LION4, LION5, respectively).

Once you’re in, you’ll be able to play some traditional casino slot classics such as Book of Dead (RTP 96.21%) and Inferno Star (RTP 96.38%), as well as new games in Gonzo’s Gold and Starburst XXXTREME.

This non GamStop casino doesn’t charge any fees for your deposits or withdrawals, but the maximum you can withdraw in one go is £5,000. Credit cards, bank transfers, e-wallets, and crypto coins are accepted.

2. Gamblezen – Best for Playing Casino Slot Games

Another CEG-licensed casino not on GamStop, Gamblezen prides itself with hosting over 10,000 casino slot games. It has partnered with over 90 software providers, including some heavy hitters like Pragmatic Play, NetEnt, and Spinomenal. Some of the most played titles on the site include Money Train 4 (Relax Gaming), Big Bass Reel Repeat (Pragmatic Play), and Old Gun (Hacksaw).

The live dealer games selection isn’t too shabby either, with Gamblezen having 542 rooms available. You can choose from a stunning number of roulette, poker, baccarat, and blackjack variations, as well as dozens of game show adaptations like Crazy Time, Dream Catcher, Monopoly Big Baller, and Football Studio.

In total, there are 10 promotional offers on the site, ranging from the 200% up to £1,500 + 100 FS highroller bonus to up to 30% weekly cashback and a 50% up to £500 + 50 FS weekend reload bonus. You may also participate in tournaments which have £10,000 prize pools.

If all this sounds interesting, you can make an account and start playing within minutes. All you have to do is submit your email, password, and country of origin.

Pros

• 10,000+ Casino Slot Games Available
• 542 Live Dealer Rooms Across Game Shows & Table Games
• Up to 30% Weekly Cashback

Cons

• Customer Support is Sometimes Slow

3. Crazy Star – Largest Collection of Lotteries With Grand Prizes

We’ll start off this mini review of Crazy Star by mentioning the casino’s lottery situation. At any given time, there are four active ones, the largest of which is the Wheel of Fortune with a £30,000 in prize pool and Free Spins for 3 different casino games. There are also slot tournaments you can participate in and win cash prizes.

Crazy Star is partnered with 95 software providers and has an impressive selection of casino games, albeit slightly smaller than the best non-GamStop sites. Some of these include Wild Bandito (PG Soft, RTP 96.73%), Hot Choice (Amatic, RTP 95.83%), and Lion Gems 3 Pots: Hold and Win (Playson, RTP 95.76%).

If you want to break routine and play some simpler, more luck-based games, this non-GamStop casino site has more than 50 crash game titles for you to try, such as Deep Dive, LaunchX, Hungry Frog, and Aviator.

As a new user on the site, you will be given a 100% up to £1,000 + 100 Free Spins (to be used in Merge Up) welcome bonus. £20 is the minimum amount you need to deposit to claim this bonus offer.

Pros

• 4 Active Lotteries at Any Given Time
• 50+ Crash Game Titles Available
• Registration With Only Email and Password

Cons

• Website Aesthetic Could be Better

4. BassWin – Best for Playing Crash Games (138 Options)

One incredible feature of the BassWin non GamStop casino site is just how many crash/instant games you’ll find there. The average among the best gambling sites is 20 to 30, but BassWin has a total of 138! These games are fast and simple, entirely relying on RNG, but the sheer number of them will keep you entertained for a while.

And if you ever want to change things up, the casino games section is packed as well. British players’ favourite titles on this casino site are 3 Clover Pots (Booongo, 95.74% RTP), Joker’s Fire Bar Hold and Win (Heaven of 7, 96% RTP), and 3 Hot Chillies (Booongo, 95.74% RTP). The full number of casino games is around 4,000.

The minimum deposit on the site is £10 but if you deposit at least £25, you’ll be eligible for the 75% up to £1,000 + 50 FS welcome reward. The Free Spins can be spent on the Big Bass Bonanza slot game.

There is also 24/7 live chat support for any potential issues you may encounter, and the website is fully mobile-optimised, allowing you to play on your mobile device easily.

Pros

• Expansive Library of Crash Games at 138 Options
• 24/7 Live Chat Support for Issue Resolution
• Regular Tournaments and Lotteries to Participate In

Cons

• Wagering Requirement is Higher Than Average (x45)

5. Bonus Strike – Best Refer-a-Friend Feature

As one of the older non GamStop casinos for British players (established in 2022), Bonus Strike quickly rose to prominence due to its open-ended approach to new user rewards. In total, you can get 725 Free Spins from your first three deposits. The first deposit bonus is 100 Free Spins for the Candy Monsta slot game, with a £20 minimum deposit requirement.

You can register on the site with your email and password, and you can also set your preferred currency. One incredibly generous feature of this site is the refer-a-friend program, where you can get a personalised link to invite a friend to join the site. Once they create an account and deposit at least £10, both of you will get £50 to your bankroll!

Then, it’s a matter of playing some casino games. Bonus Strike has a good combination of slots, table games, live casino games, and crash games. Additionally, there are dozens of bingo, plinko, slingo, pachinko, and limbo entertainment options. In a sense, this casino not on GamStop caters to all sorts of players.

Pros

• Dozens of Bingo, Plinko, and Slingo Options
• £50 Given to You and a Friend You Referred
• 725 Total Free Spins From Initial Deposits

Cons

• Only Credit Cards Available for Transactions

6. Love Casino – Best Welcome Bonus for New Players

One fairly helpful feature that we’ve found on this casino is the ‘Wins’ or ‘Jackpots’ ticker. This shows the latest casino slot winners by displaying their country of origin, casino username, win amount, and the game they’ve won at. Useful information to know since you may adjust your gambling strategy after seeing how others are doing.

The non GamStop casino site has 5 total welcome packages and that’s basically it for the promotions. But, if you manage to claim all five, you’ll get a total of 950% up to £6,000 + 175 Free Spins. The first deposit bonus is 400% up to £2,000 and 100 FS.

Similarly to some top casinos outside GamStop, Love Casino has zero associated fees with both deposits and withdrawals. You can deposit a maximum of £1,000 in one go, and withdraw a maximum of £5,000 (processed between 24 and 48 hours).

While the live casino game library isn’t as impressive as some other non-GamStop gambling sites, the overall number of games you can play on the site is 4,000+.

Pros

• Generous 400% Up to £2,000 + 100 FS Welcome Offer
• Jackpot/Wins Ticker Showcasing Other Players’ Success
• No Fees for Withdrawals or Deposits

Cons

• Live Casino Game Library Could Be Bigger

7. Golden Genie – Best Usability on Mobile Devices

Golden Genie’s welcome bonus is similar to Love Casino’s, in that you will receive a 400% up to £2,000 + 100 Free Spins first deposit boost. You can spend your free spins on the Wish Master slot game (RTP 96.65%). The wagering requirement is x50, which is above the x40 average, making it more difficult for players to achieve.

However, the minimum deposit is just £20 and this applies to all other bonuses as well. Account registration on the site is straightforward, but you will have to submit your phone number so it may take a minute or two longer than at other non-GamStop sites.

The site accepts all major payment methods, including credit cards, e-wallets, bank transfers, and crypto coins. Withdrawals are fast (average processing speed of 24 hours), and there are no fees for any transaction you make.

Some notable casino games include Boat Bonanza (RTP 96.21%), Starburst (RTP 96.09%), and Gonzo’s Quest (RTP 95.97%). In total, Golden Genie offers more than 3,000 provably fair casino titles from 40 software providers.

Pros

• All Major Payment Methods are Supported
• Curacao Gambling Licence Guaranteeing Fast Withdrawals
• No Transaction Fee for Any Payment Option

Cons

• Higher Than Average Bonus Wagering Requirement (x50)

8. Lucky Mister – Best for Playing Table Games (360+ Options)

Lucky Mister is partnered with an incredible 155 software providers that have created tons of provably fair games for this site. More specifically, there are 3,250+ titles to choose from. While its game library is smaller than some other non-GamStop casino sites, it is regularly maintained and new games are constantly being added.

We particularly enjoyed the table games selection for two reasons. One, you can play 360 different table games and two, you’ll find some fairly unique options. Some of these include Pontoon, Top Card Trumps, Fortune Dice, and Color Dish 2. Lastly, certain games feature adult (18+) themes.

Another feature we liked about this site is the clear approach to responsible gambling. Firstly, if you think you have a gambling problem, all you have to do is reach out to the support staff via phone call, and they will block you from accessing the site for some time. Lucky Mister also lists 9 third-party resources that can help with managing how you approach gambling.

Support is available 24/7 through live chat, but you can also reach them by sending an email.

Pros

• 360+ Traditional and Unique Table Games
• Partnerships With 155 Trusted Software Providers
• Helpful Responsible Gambling & Self-Exclusion Tools

Cons

• Game Library Could Be Larger

9. Richy Leo – Best for Competing in Slot Tournaments

If you’re one to be better than other people at something, Richy Leo is the ideal place to show competing British players who’s the boss. The site hosts a weekly tournament with a £2,000 prize pool. First place also gets 200 Free Spins.

Additional promotions you can find on the site are rewards for your first four deposits. Firstly, you can claim the 10% up to £1,000 + 10 FS new user bonus. Unfortunately, this is where Richy Leo falls relatively short compared to most non-GamStop casinos, as the bonuses could be better and bigger.

Nonetheless, the overall gambling experience is highly positive, with thousands of popular and new casino titles. Coin Up Lightning, Pink Joker, and Hit More Gold Hold and Win are the most player games on the site, while the newest options include Clover Coins 4×4 (TaDa Gaming), 3 Pots of Lunar Wolf (BetSoft), and Bob Marlin Goes Splashing (Yggdrasil).

Oh, and there are two lotteries you can join; the Book of Jackpots (£10,000 prize pool) and Jackpot Time (£40,000 prize pool).

Pros

• Frequent Weekly Tournaments With £2,000 Prize Pools
• Two Lotteries With £10,000+ in Prize Money
• New Casino Slot Games are Released Constantly

Cons

• Bonuses to Deposits Are Average

10. Royal Fortune – Best for Making Transactions With Crypto

Lastly, we reach the Royal Fortune casino not on GamStop. This gambling site has been around for a year (launched in 2024) and it has the Costa Rica gambling licence. Account registration requires an email, username, password, and phone number for account verification purposes.

There’s a healthy dose of promotions on the site, such as the 200% up to £1,000 + 50 Free Spins welcome offer. You will also be able to claim the 300% up to £1,000 crypto deposit boost, a 50% reload bonus on weekends, and 10% cashback up to £500 per week. You may also get free bets and a sports welcome bonus if you’re also a punter.

The live casino selection has 295+ rooms, including traditional options like Caribbean Stud Poker, Red Door Roulette, and Blackjack. Interestingly, Royal Fortune has a ‘Stock Market’ live casino game from Evolution Gaming.

If you prefer slots, we recommend checking out the non-GamStop casino’s jackpot games library, since there are some rare games in there. Some of these are Great 27, 40 Lucky King, Caishen’s Gold, and Seven’s Fire.

Pros

• 300% Up to £1,000 Crypto Deposit Bonus
• Expansive Cryptocurrency Support (6+ Crypto Coins)
• Costa Rica Licence for Full Legitimacy and Fair Gambling

Cons

• No Crash/Instant Games

Our Process for Reviewing and Rating Non-GamStop Casinos

We follow a specific route toward fully reviewing a non GamStop site. This enables us to cover all the details so we can bring you a detailed and impartial analysis of what these sites offer.

Licensing and Security Measures

Firstly, we make sure that the casino in question is sufficiently licensed. It can be any of the leading licensing bodies, such as Curacao, Malta, etc. If the site does not have a licence to operate, we do not review it further.

During this step, we also have a look at the site’s security measures, including SSL Encryption, 2FA, and more.

Non GamStop Casinos Reputation

British players like yourself frequently share their experiences about the casinos not on GamStop they visit. While we can provide a detailed overview of each, we cannot summarise them based on personal experiences. That is why taking a casino’s reputation among players into account is imperative for painting the full picture.

Unique Features

Apart from simply comparing the same features that non-GamStop casinos exhibit (e.g. game library size), we also look at any unique or particularly interesting features that may not be found elsewhere. Examples include mobile app existence, additional filtering options for games, VIP account managers, etc.

Bonuses and Promotions at Non GamStop Casinos

Tournaments, lotteries, welcome bonuses, free spins, and cashback offers. These are common elements of a casino’s promotional repertoire and are vastly important for keeping players interested and engaged.

The larger and more frequent the bonuses, the higher the scores, but we also consider wagering requirements, minimum deposits, and any other terms associated with the bonuses.

Non-GamStop Casino Sites Compared - Our 2025 Top List

Our resident writer and researcher, David Burns, has reviewed hundreds of non-GamStop casinos. Here is a quick comparison of the best ones in 2025:

Key Differences Between UK-Licensed and Non-GamStop Casinos

While similar in many regards, there are some stark differences between UKGC casinos and non-GamStop gambling sites. Our researcher David Burns explains them below:

Wagering Limits and Highroller Access

The UKGC severely limits how much players can wager and what they can get from bonuses. This essentially dissuades highrollers from even using UKGC sites, since they won’t be able to play the way they want to. On the other side, non-GamStop sites have elevated wagering limits (up to £5,000 or more), allowing riskier but potentially more rewarding plays.

Self-Exclusion Programs

GamStop is a mandatory self-exclusion scheme that all British players and UKGC casinos are a part of. Once you’re in GamStop, you won’t have access to any UKGC gambling sites. Since non GamStop sites have international licences, their self-exclusion programs are optional, as the UKGC does not have jurisdiction over them.

Payment Options and Withdrawal Speeds

Credit cards and cryptocurrencies are disallowed at UK-licensed sites, so your only options are bank transfers, debit cards, and a limited number of e-wallets. The situation is completely different at non-UKGC casinos, where you’ll often be rewarded for using cryptocurrencies. Also, withdrawal speeds are much faster as there aren’t any ID and financial verification checks.

Player Anonymity and Privacy

All UKGC sites are required to gather personal information for the purposes of confirming players’ identities. Players must submit their IDs for verification, which many don’t agree with as it means sharing sensitive details with gambling sites. There are no such processes on non GamStop casino sites, allowing almost complete anonymity and data privacy.

Today’s Biggest Bonuses at Non-GamStop Casino Sites

As time went by, non-GamStop sites started offering larger and better bonuses to attract more new players than their competitors. Nowadays, each casino has multiple promotions, of which the most impactful ones are:

Loyalty and Reward Programs

David Burns argues that loyalty and VIP program rewards are perfect for all players. His reasoning is that you’re constantly gaining XP or LVL UP points, which in turn improve the rewards you get.

Essentially, the financial impact is weaker than what a new player goes through when they register an account.

Welcome Bonus

The first bonus all players get is the welcome bonus. It generally consists of a specific first deposit boost (e.g. BassWin’s 150% up to £1,000 + 100 FS) and, as can be seen from BassWin’s bonus, a number of Free Spins.

Keep in mind that these bonuses have certain terms you need to fulfil before claiming them (wagering requirement, minimum deposit, etc.).

Refer-a-Friend Bonuses

While not too common among the best non GamStop casino sites, refer-a-friend bonuses are a great way to be rewarded for inviting your friend to play at the same casino. You will either get some Free Spins or a deposit boost, depending on the casino’s approach to this bonus.

Leading Game Providers at Non-GamStop Casinos in 2025

Partnering with reputable software providers is the only way for non-GamStop sites to offer a provably fair, entertaining, and rewarding gambling experience. Some of the most well-known casino game developers are:

Betsoft

Betsoft is a fairly versatile software provider as it has created titles related to slots as well as table games. They’ve also released dozens of high-RTP (97%) games for players looking to potentially win slightly more often. You’re probably familiar with slots, such as Coins of Zeus and Charms and Treasures, while some table game releases include Oasis Poker and European Roulette.

Relax Gaming

Relax Gaming is best known for its extensive slot game collection that features a rich variety of themes, including sports, archaeology, and myths. This software developer has released more than 250 titles, catering to all sorts of players. Arguably, their most famous titles are 5 Wild Buffalo (96.01% RTP), 7 Gold Fruits (96% RTP), and Temple Tumble (96.25% RTP).

Thunderkick

Pink Elephants 2, Esqueleto Explosivo 2, and The Wildos 2. What do they all have in common? They’re full sequels to the first mainline Thunderkick games, which is a specific trait of this casino game provider. Additionally, Thunderkick games feature unique and intriguing storylines and themes, such is the case in Arcader, 1429 Uncharted Seas, and more.

Iron Dog Studio

Iron Dog Studio is a newer software provider that has established itself among the greats, thanks to its library of 99 games it has created. The developer constantly releases new titles, and at the time of writing, there were 5 games in development – 3 Wicked Devils, Train Strike, 3 Cheeky Chimps, Cowboy Showdown, and Crazy Tiki.

Newly Launched Non-GamStop Casinos to Try in 2025

New non-GamStop sites appear every once in a while with fresh gambling experiences and offers. Here’s a quick breakdown of some young casinos you should try:

How to Deposit and Withdraw at Non-GamStop Casinos

First off, you’ll need to have an account at your chosen non-GamStop gambling site. Once there, navigate to the ‘Payments’ or ‘Deposits’ section to see which payment options are available to you.

You won’t have access to PayPal, Google Pay, or Apple Pay as these methods are available only at UKGC sites. However, there are plenty of other options to choose from, explained below:

• Credit Cards: Visa and Mastercard are the most commonly available cards, but American Express is also supported in rare instances. It can take up to 24 hours for a withdrawal with a credit card to clear.
• Prepaid Cards: These are only available for depositing except in very specific circumstances, with the popular option being Paysafecard. They’re excellent for managing the exact amounts you want to deposit, without overspending.
• E-Wallets: Fast, secure, but with higher fees, e-wallets like Skrill, Neteller, AstroPay, and many others are available at most non-GamStop sites. Deposits are instant, while withdrawals are generally completed within 48 hours.
• Bank Transfers: Bank transfers are the slowest but most secure option, the success of which depends entirely on your bank. Certain banks will block gambling-related transactions so it’s best to check with them first before committing to a bank transfer withdrawal.
• Crypto Coins: Crypto is the fastest withdrawal method that has zero fees and full anonymity. Withdrawing your winnings usually takes just a few minutes, and you’ll only have to connect your crypto wallet with the site. Bitcoin, Ethereum, and Litecoin are the most accepted coins.

Real Experiences From UK Gamblers at Non-GamStop Casinos

As mentioned previously in this article, we always take user accounts into consideration when reviewing non-GamStop sites. Here are a couple about such casinos in general:

Helga Stevens: “Luv being able to play my bingo and bet on horses on Gamblezen. I’m in GamStop so this is a welcome ability”

Norman Gramsby: “One thing I like about international sites is that I can use my crypto savings for some betting on the side. Fast transactions too!”

Adam Lambert: “I’ve been having trouble with my bank, been declining my withdrawals but at least I got my Skrill account to work with”

Marcus Ellsen: “Sometimes the site is slow but BassWin makes betting on footy so easy. Got myself a nice win after Arsenal clobbered Leeds”

Nigel Parish: “I like to tune in on the evenings to watch some NBA. Sometimes, a casino I use will give me a basketball deposit bonus. I really enjoy those”

How to Detect Reliable Non-GamStop Casinos

Equip yourself with the following methods to make sure the non-GamStop casinos you’re interested in are legitimate and reliable to use:

• Fully Licensed: First off, you want to determine if the casino has a valid gambling licence. Look for information about it on the website (usually located in the Footer).
• Has Exciting but Realistic Bonuses: Non-GamStop casinos have larger bonuses than UKGC sites, but avoid casinos that have unrealistic rewards (e.g. 1,000% up to £10,000).
• Doesn’t Require ID Verification: ID verification is not needed when registering an account at a non-UKGC casino, so your sensitive personal info is kept anonymous.
• Customer Support is Efficient: No matter how good a casino website is designed, occasional issues may arise. A customer support team you can trust is a sign of casino legitimacy.
• Games by Trusted Software Providers: Casino games from renowned software providers are tested and audited, guaranteeing a provably fair gambling experience. Avoid sites that host games from unknown game providers.
• Accepts Cryptocurrencies: Cryptocurrencies have become a popular choice due to security, zero fees, and instant transactions. A licence enables non-GamStop sites to accept crypto.
• Offers Optional Responsible Gambling Tools: Legitimate non-GamStop casinos look out for their players’ well-being by providing optional responsible gambling tools to prevent gambling problems.

Gambling Responsibly: Alternatives to GamStop for Self-Exclusion

GamStop is quite a limiting factor for many British players, but it exists as a form of gambling help. Some third-party self-exclusion options can aid in preventing gambling problems.

BetBlocker

BetBlocker is an app you can install which limits or blocks access to popular casinos, including if you’re using a VPN. You can set up the app within minutes, schedule when you want access to be revoked, and it’s completely free to use!

Gamban

Another mobile/PC self-exclusion app, Gamban takes it a step further by blocking virtually all non-GamStop and UKGC-licensed sites so you can’t visit them. The app also monitors your progress, adding a gamified element to keep you feeling successful. Once you install it on one platform (e.g. mobile), you’ll be able to activate it on all devices you use.

Net Nanny / Qustodio

Net Nanny is a form of parental control or oversight of what their child is doing. But it can also be used as a way of monitoring your own online activity at casino sites. Qustodio is essentially the same type of app with slightly different functionality.

Bank Card Blocking

You may choose to block your bank card (Visa, Mastercard, AMEX) from being used as your preferred payment method. Excellent if you have a credit card that you thought of using for deposits, as it may increase your bank debt as well. Some casino sites provide this option, but if not, you can contact your bank for help.

Conclusion

Whether you’re currently in self-exclusion and want to circumvent it via an alternative route or you just want to enjoy the benefits, non-GamStop casino sites are the perfect choice. Their offshore licensing allows more versatility for bonuses, accepted payment methods, game library size, and easier account registration.

On the other hand, all responsible gambling tools are optional, so some sites may have fewer such tools than others. And, albeit rare, withdrawal issues may occur, prolonging the entire process. Add to that the fact that the UKGC won’t be able to help you in case of disputes, so you’ll have to follow player safety practices to utilise these gambling sites fully.
