New to sites not on GamStop? We review the casinos below on what players ask first: how fast you get paid, what a welcome bonus really costs, which methods pay out and what you get once the welcome is spent. We also say what to check before you sign up. None of these sites is licensed by the UK Gambling Commission, so GAMSTOP cannot block you there and the Commission has no say in a dispute.

We make sure UK residents can join and hold pounds, and note the currency of the limits.
We work out what each stage asks you to stake, the bet limit, the time you get and the most it can pay out.
We check which deposit methods also pay you back, how fast each one pays and what you may be asked to prove first.
We look at cashback, reloads, tournaments, loyalty levels and sport, and at the wagering each of them carries.
We check which limits, breaks and exclusions you can switch on yourself, and whether support is open around the clock.
Each review opens with what a casino not on GamStop offers once the welcome is over, then turns to payouts and the bonus. First, the basics of all five:
| Brand | Welcome offer | Wagering | Smallest withdrawal | Payout caps |
|---|---|---|---|---|
| Britsino | Four deposits; at the highest tiers £2,000 and 700 free spins in all | 35x the bonus | £20 | Day: £2,000; week: £5,000; month: £20,000 |
| Betnjet | Three deposits; 400%, up to £1,000 and 250 free spins | 35x the bonus; 20x on the high-roller offer, 45x on the crypto one | £50 | Day: £1,000; week: £5,000; month: £15,000 |
| Amunbet | Three deposits; 450%, up to £2,700 and 450 free spins | 35x the bonus | £18 | Week: €3,000; month: €15,000 |
| Reveryplay | Three deposits, no codes; €5,000 and 250 free spins at most | 40x on the first two stages, 30x on the last | £20 | Day: €4,000 (€1,000 on a new account); week: €8,000; month: €30,000 |
| Elarabet | Three deposits, no codes; €5,000 and 300 free spins at most | 40x on each stage | £20 | Day: €4,000 (€1,000 on a new account); week: €8,000; month: €30,000 |
This order is our own view, weighed against the checks set out lower on the page, and no score. All figures come from the casinos' own websites; we did not sign up or play at any of them. Where a casino gives a sum in euros, we keep it in euros.
We may earn a commission when you open an account through links on this site; it does not decide the order or what we write.
Britsino gives regulars something to chase every week. The Brick Battle tournament puts up £700 and 8,000 free spins, a lottery draws £325 and 1,500 free spins each Thursday, and the Thunder Joker network tournament takes only players from the UK and Australia. You can keep a balance in pounds, and the promotions are priced in £.
Britsino in brief:
| Detail | Value |
|---|---|
| Licence | Not stated |
| Games | More than 6,000 slots, plus live, table, scratch and jackpot games; 55+ providers |
| Welcome offer | Up to £2,000 and 700 free spins over 4 deposits, at the highest tiers |
| Wagering | 35x the bonus, 7 days to clear it, bets up to £5 |
| Min. deposit / withdrawal | £20 each |
| Withdrawal time and limits | Paid within 24 hours; day £2,000, week £5,000, month £20,000 |
| Players from the United Kingdom | Yes, with a GBP balance and offers in £ |
Britsino pays winnings within 24 hours, e-wallets within 1 working day after verification, and VIPs first. The caps are £2,000 a day, £5,000 a week and £20,000 a month, and no other casino here sets a higher monthly limit in pounds.
Ten cryptocurrencies sit beside GBP, EUR and USD. Wager each deposit 3x before you withdraw it, or a fee may apply, and expect requests for ID, proof of address or financial statements.
The welcome runs over four deposits, and the size of each deposit sets your tier. With code ALBION, the first brings 100% up to £100 and 80 spins from £20, up to £300 and 150 spins from £60, or up to £600 and 300 spins from £180. Codes CAMDEN, HAMPSTE and BLOOMSB then pay 75%, 75% and 100%, up to £400, £600 and £400 at the top tier.
Now the catch. Spins are worth £0.10, so the 300 top-tier spins are £30 of play, and their winnings stop at £100. You get 72 hours to claim a stage and a week to bet it 35 times over, at up to £5 a bet: the full £600 first stage means £21,000 in bets. Jackpot and bonus-buy games do not count, and a bonus pays 10x its size at most.
Beyond the weekly prizes, monthly cashback of 2–10% is capped at £300 to £5,000 by status, and rakeback, paid weekly at 2–10%, at £200 to £1,000; both carry 40x. The 100 loyalty levels pay up to £182,172 and 2,240 spins over the climb, and a VIP host looks after you once you have deposited £1,000.
Pros
Cons
It fits a slots regular who plays in pounds, wants a weekly prize to aim for and likes firm caps on losses and session time.
In your first week, Betnjet pays 10% cashback up to £150 once you have deposited £500, and asks only 2x wagering on it, where Britsino asks 40x on its cashback and Reveryplay and Elarabet 5x on Monday live cashback. You can hold pounds, and the bonus terms give every sum in € and £.
Betnjet in brief:
| Detail | Value |
|---|---|
| Licence | Not stated |
| Games | Live casino, crash games, jackpot and regular slots |
| Welcome offer | Three deposits: 400%, up to £1,000 and 250 spins |
| Wagering | 35x bonus only; high-roller 20x; crypto 45x; bets up to £5 |
| Min. deposit / withdrawal | £20 in, £50 out |
| Withdrawal time and limits | Bank and crypto instant, no fee; day £1,000, week £5,000, month £15,000 |
| Players from the United Kingdom | Yes, with a GBP balance; bonus sums in € and £ |
Bank and crypto withdrawals cost nothing and are instant. Up to £4,000 at a time goes to N26, Deutsche Bank, Revolut or Postbank, and up to £1,000 to Commerzbank, so check that your own bank is on the list. Deposits go in by Paysafecard, bank or coin.
The limits are where it pinches. A withdrawal starts at £50, the highest minimum of the five, and stops at £1,000 a day, half of Britsino's, with a weekly £5,000 and a monthly £15,000 on top. In return, deposits only have to be wagered twice before you can take them out fee-free.
The casino welcome comes in three parts, each from a £20 deposit: code 120 gives 120% up to £200 and 100 spins, code 130 gives 130% up to £300, and code 150 gives 150% up to £500 and 150 spins. Wagering is 35x the bonus only, spins are worth £0.20, bets stop at £5 and each non-sticky bonus lasts 7 days.
Here is the catch: every part of it has a win cap. Winnings stop at £1,000 from the first bonus and another £1,000 from its spins, at £1,500 from the second bonus and at £2,500 from the third, five times the £500 top stage. High rollers depositing £150 and then £200 get 50% up to £1,000 and £1,500 at 20x, while the crypto welcome carries 45x.
Each day opens with 50 free spins for a £30 deposit at 30x, and the Jet Mission adds 100 spins for seven £20 deposits within 7 days. Sport has its own welcome of up to €1,700 in only-win free bets. Status points build at 1 per €50 on slots, and from level 5 of 11 you get 5–10% weekly cashback.
Pros
Cons
It fits a new player who wants a cushion in the first week and is happy to cash out £1,000 a day or less.
Amunbet is built for someone who follows the Premier League as closely as the slots. Football, basketball, tennis and MMA are all on its sportsbook, pre-match and live, with cash-out and markets from 1X2 to Asian Handicap and BTTS. Promotions and VIP rewards are priced in pounds, and withdrawals start at £18, the lowest minimum here.
Amunbet in brief:
| Detail | Value |
|---|---|
| Licence | Not stated |
| Games | Slots, live tables and crash games in the thousands, from Pragmatic Play, Evolution, NetEnt and others |
| Welcome offer | 450%, up to £2,700 and 450 spins, 3 deposits from £18 |
| Wagering | 35x the bonus and spin winnings; bets up to £4.50; cashout capped at the bonus |
| Min. deposit / withdrawal | £18 each |
| Withdrawal time and limits | Instant in crypto, 1–3 days by card, 5–7 by bank; €3,000 weekly or €15,000 monthly at most |
| Players from the United Kingdom | Yes, with a GBP balance and promotions in pounds |
Crypto is the only instant way out, from 20 to 4,000 USDT a time. A card payout needs 1–3 days and a bank one 5–7, both between £18 and £3,600, where the bank route at Reveryplay and Elarabet takes 2–3 days. Amunbet charges no fee, but your payment provider may, and the caps are set in euros: no more than €3,000 weekly or €15,000 monthly.
Card and bank deposits start at £18 and are instant and free. Wager each deposit 3x before you withdraw it, or a fee may apply, and expect to upload ID and proof of address before a payout.
The welcome is three deposits from £18, each worth up to £900: AMUN1 pays 150% and 100 spins, AMUN2 100% and 150 spins, AMUN3 200% and 200 spins. Wagering is 35x the bonus only, spin winnings stop at £135, bets at £4.50, the lowest max bet of the five, and the bonus lasts 7 days. From £450, the ROYAL1 high-roller offer gives 250% up to £4,500 plus 250 spins.
Now the catch: a bonus can never cash out more than its own size. A £450 deposit at the third stage brings the full £900, and 35x means £31,500 in slot bets for a bonus that can turn into £900 at most. Every game except slots counts 0%.
The Golden Weekend Ladder can be claimed up to 5 times a weekend, and the bigger the match, the lighter the wagering: from 50% at 40x to 100% up to £750 at 30x. Million Drops, a network tournament, offers €1,000,000, the largest prize pool here, and nine ranks from Anubis to Amun-Ra add daily cashback of 4–15% at 25x. It all plays in an iOS or Android browser.
Pros
Cons
It fits a football or tennis bettor who also plays slots, cashes out small sums from £18 and sees the welcome as extra play, not a route to a big win.
Open since October 2025, Reveryplay answers its English live chat in about 3 minutes, day and night, and runs on your phone as a Progressive Web App. Behind it sit 5,000+ games by 100-plus providers, eight blackjack variants among them, and a book of 45 sports.
Reveryplay in brief:
| Detail | Value |
|---|---|
| Launched | October 2025 |
| Licence | Not stated |
| Games | Over 5,000, about 80% of them slots |
| Welcome offer | €5,000 and 250 spins at most, over 3 deposits from £20, no codes |
| Wagering | Stages 1 and 2 at 40x, stage 3 at 30x; bets up to £5 |
| Min. deposit / withdrawal | £20 each |
| Withdrawal time and limits | Instant by card or crypto, 2–3 days by bank; day €4,000 (€1,000 on a new account), week €8,000, month €30,000 |
| Players from the United Kingdom | Yes, with a GBP balance; Gibraltar, Guernsey, Jersey and the Isle of Man excluded |
Reveryplay processes a withdrawal within 24 hours, and the first one also starts identity checks. Once approved, money reaches a card or crypto wallet straight away, while a bank transfer needs 2–3 days; card and bank both stop at £4,000 a time. Deposits start at £20, by card, bank, Apple Pay, Google Pay or 11 coins.
A young account is held back. While you have fewer than 10 deposits or under €1,000 deposited, you can withdraw €1,000 a day rather than €4,000, and wins above €30,000 arrive in monthly instalments. Each deposit must be wagered three times on slots or ten times on anything else, or a fee may apply.
You need no codes. Deposit one brings 100% up to €1,000 plus 100 spins and deposit two 125% up to €1,500 plus 100 spins; both carry 40x. Deposit three adds 75% up to €2,500 plus 50 spins, at 30x. Each stage starts at £20, the maximum bet is £5 and spins have to be activated within a day.
Size is only half the story. A bonus pays out 10x its value at most, and winnings from spins are capped at £100. Britsino, Betnjet and Amunbet ask 35x, so the 40x here is heavier: the full €1,500 of the second stage needs €60,000 in bets within 7 days.
Racing fans get horse and greyhound markets, esports sit alongside, and some markets allow cash-out; welcome free bets go to a maximum of €100, €150 and €200. Wednesdays bring 55% up to €555, Monday Live Cashback gives back 10%, capped at €5,000, at 5x, and the 12 loyalty levels end in a €5,000 bonus and 15% cashback every day, capped at €3,000.
Pros
Cons
It fits a player who wants a quick answer from support, bets on racing now and then and can be patient with withdrawals while the account is new.
Elarabet names more live-casino studios than any other site here: Evolution, Ezugi, 7mojos Live, Pragmatic Play Live, Betgames and Swintt Live. They sit inside a lobby of more than 10,000 games by over 100 studios, the largest of the five. Launched in 2026, it runs in English (UK).
Elarabet in brief:
| Detail | Value |
|---|---|
| Launched | 2026 |
| Licence | Not stated |
| Games | 10,000+ in all; live tables from six studios |
| Welcome offer | €5,000 and 300 spins at most, 3 deposits from £20, no codes |
| Wagering | 40x the bonus at each stage; bets up to £5; one bonus at a time |
| Min. deposit / withdrawal | £20 each |
| Withdrawal time and limits | Instant by card or crypto, 2–3 days by bank; day €4,000 (€1,000 on a new account), week €8,000, month €30,000 |
| Players from the United Kingdom | Yes, with a GBP balance and an English (UK) site |
Elarabet's cashier mirrors Reveryplay's: up to 24 hours of processing, then card and coin payouts land straight away and bank transfers need 2–3 days, with £4,000 the most per card or bank withdrawal. You can hold pounds, euros or coins from BTC to SOL.
The same €1,000 daily ceiling applies while you have fewer than ten deposits or under €1,000 paid in. Elarabet can check your ID, address and payment method before the first withdrawal or at any time, with 7 days to send documents, and a deposit needs 3x on slots or 10x elsewhere, or a fee may apply.
No codes here either: the first deposit earns 100% up to €1,500 and 100 spins, the second 125% up to €1,000 and 50, the third 75% up to €2,500 and 150, each from £20. A bonus can pay out 10x its size, winnings from spins top out at £100, and the bet limit is £5. A high-roller pack spreads up to €15,000 and 500 spins over five deposits from £100.
The price is the wagering: 40x the bonus applies to every stage and to the high-roller pack as well, where Britsino, Betnjet and Amunbet ask 35x. The full €2,500 of the third stage needs €100,000 in bets, while Reveryplay's third stage of the same size asks €75,000 at 30x.
The Big Sunday Blast tournament puts €25,000 up every Sunday, the same day 5% cashback on new games comes back at 5x. The sportsbook's welcome free bets carry no wagering, at £200, £250 and £300 at most. Reach level 8 of 12 and the loyalty scheme starts paying cash, €500 to €5,000, plus a daily cashback of 5–15%.
Pros
Cons
It fits a live-casino player who wants a wide choice of studios, bets on sport with free bets that need no wagering, and can leave the 40x welcome alone.
Once the welcome is spent, the five differ most in what a bonus can return, what a deposit must do before it leaves and how they reward you for staying:
| Brand | Most the welcome can pay | Deposit turnover | Loyalty | Regular cashback |
|---|---|---|---|---|
| Britsino | 10 times the bonus | Three times | 100 levels, a host from £1,000 in deposits | 2–10% monthly, at 40x |
| Betnjet | Fixed caps of £1,000, £1,500 and £2,500 | Twice | 11 levels, a VIP manager at level 8 | 5–10% weekly from level 5 |
| Amunbet | No more than the bonus | Three times | 9 ranks with a VIP manager | 4–15% daily, at 25x |
| Reveryplay | 10 times the bonus | 3 times on slots, 10 on other games | 12 levels, a manager at level 8 | Top tier 15% daily; live 10% on Mondays, at 5x |
| Elarabet | 10 times the bonus | 3 times on slots, 10 on other games | 12 levels, cash from level 8 | 5–15% daily from level 8; live 5% on Mondays, at 5x |
Read across and every strength has a cost: Betnjet clears deposits at 2x but caps each stage, Amunbet pays cashback daily but limits a bonus to its own size, and Britsino's 100 levels come with 40x on its cashback.
A non GamStop casino is an online casino that holds no licence from the UK Gambling Commission and has no connection to GAMSTOP, Great Britain's free self-exclusion scheme. The label tells you what a site is outside of, not how well it is run, and many such sites hold a licence from a regulator abroad instead.
People come to them for larger welcome offers, crypto banking and casino and sport on one balance. What they give up is the UK safety net: a GAMSTOP registration does not reach them, the Commission cannot help with a complaint and the £5 online slot stake limit does not apply.
GAMSTOP costs nothing. You choose a period of 6 months, 1 year or 5 years, and for that time any online operator holding a UK Gambling Commission licence must refuse you. The end date does not switch your access back on by itself: once the period is over, you contact GAMSTOP to lift it, and a cooling-off period follows.
The scheme has clear edges. It covers online gambling in Great Britain, the market the Commission licenses; Northern Ireland sits under a separate gambling law. It does not reach land-based venues, and sites licensed overseas have no link to it.
So what does a site not on GamStop offer instead? Its own self-exclusion, which closes your account at that one casino. It is a real tool, but a narrow one: one account at one site, against a GAMSTOP block of up to 5 years at every licensed operator.
Should you stick with a casino the UK Gambling Commission licenses, or try one that is not on GamStop? Here is what changes, area by area:
| What you get | With a UKGC licence | Not on GamStop |
|---|---|---|
| Self-exclusion | One GAMSTOP registration shuts you out of every licensed online site | Only the casino's own tool, closing one account |
| Complaints | An unresolved dispute is passed to an approved ADR provider, free for you | Handled by the casino itself; the UKGC has no jurisdiction |
| Stakes on slots | £5 per spin at most online, lower under 25 | Whatever the casino sets; often a cap only while a bonus runs |
| Credit cards | Banned for gambling from April 2020 | Some sites take them |
| ID checks | Age and ID checked before the first bet | Often only at the first withdrawal |
| Deposit limits | Must be offered to every player | Offered at most sites, switched on by you |
Outside the Commission's reach, the free ADR route is closed. If a site names a regulator abroad, its rules decide whether a complaint goes anywhere, so look before you deposit; the licence section below shows how.
These sites compete hard on welcome packages, reloads, cashback, tournaments and loyalty ladders. The wagering, the bet limit and the cap on winnings decide what each one is worth.
Crypto usually sits beside cards and bank transfers, and many sites hold balances in several currencies. A crypto payout can land minutes after approval, while a bank payout may need several working days.
This is the biggest change. Limits, breaks and self-exclusion exist at most of these casinos, but they apply to a single account, and you have to turn them on.
These sites suit adults who want more choice in offers and payments and can do without the UK's safeguards; they do not suit anyone who has chosen to stop.
Pros
Cons
A casino joins the shortlist only if it passes five checks, in this order:
We also weigh what comes after the welcome, since most of your play will meet it: cashback, reloads, tournaments, loyalty and sport.
Some things rule a casino out whatever the bonus: a restricted-country list that includes the UK, or advice to connect through a VPN. Other issues we flag in the review so you can weigh them: a ceiling on bonus winnings, cashback with heavy wagering, or a low daily limit on a new account.
Welcome offers at a casino not on GamStop rarely come as one bonus. Most are a chain of matched deposits, free spins often included, and each stage has its own rules. The big number shows the maximum, not the value; these terms decide that:
Here is an illustrative case in round figures. Say you put in £120 and get a 50% match: £60 of bonus. At 30x the bonus that is £1,800 in bets. With a £3 bet limit you need at least 600 spins, or 100 a day over 6 days. If winnings are capped at 5x the bonus, £300 is the most it can pay, however well the spins go.
Make it 30x the deposit plus the bonus and the sum becomes £180 times 30, or £5,400: three times the betting for the same £60.
Free spins are worth the spin value times the count: 40 spins at £0.25 are £10 of play (illustrative figures), and what they win is often capped. Cashback and reloads carry their own wagering, and the multiple matters more than the percentage: cashback at 1x is close to cash, cashback at 40x is not. Tournaments reward volume, so check how much play a prize really takes.
At sites not on GamStop, the simplest way to avoid a stuck payout is to pick a method that pays out as well as takes deposits. Here is how the usual options behave:
| Method | Deposits | Withdrawals | Watch out for |
|---|---|---|---|
| Cards (debit or credit) | Instant as a rule | From minutes to several working days | On a credit card you are betting borrowed money |
| Bank transfer | Usually same day | Often the slowest, up to a week | Whether your bank is one the casino pays to |
| E-wallets | Instant | Often within a working day once verified | Availability differs by country |
| Mobile wallets and vouchers | Instant | Rarely possible | Your winnings must leave another way |
| Crypto | Instant once the network confirms | Often the quickest route | The coin's price can move before you sell |
First the casino reviews the request, often within 24 hours and longer the first time. Then the bank, card scheme or blockchain moves the money: minutes for crypto, days for card and bank payouts.
Expect to show photo ID and a proof of address before you are first paid, and sometimes evidence that the payment method is yours. Send everything soon after registering: paperwork is the most common delay.
Every withdrawal has a minimum and a maximum by day, week or month, a large win may arrive in parts, and new accounts sometimes start on lower caps. If the limits are in euros and you play in pounds, ask support which rate applies.
Many hold one from a regulator abroad, and it matters most when something goes wrong. A licence is issued to a named company and gives you a place to complain once the casino has refused. In Great Britain that is a free, approved ADR provider, but the Commission's jurisdiction stops at the sites it licenses. A licence from abroad gives you what that regulator's rules give, no more.
Badges are not licences. An RNG certificate says the games are random, SSL keeps your data private and two-factor authentication guards your login, but none of them will look at a complaint.
Do it again when the terms change: licences lapse, and a site can move to another company.
Many non GamStop casino sites run a sportsbook that shares your casino balance, so one deposit funds slots, live dealers and bets. Football comes first, and the bigger books add horse and greyhound racing, MMA and esports, before the start and in play.
A sports welcome is normally paid in free bets. An only-win free bet pays the profit without the stake: a £10 free bet at odds of 5.00 returns £40, not £50 (illustrative figures). Check the lowest odds allowed, the days you have to use it and whether the winnings carry wagering.
Sport has small print of its own: a cap on accumulator odds, a deposit to stake at set odds before you withdraw, and often only a few days to dispute a settled bet.
With no UK regulator to turn to, the support team is your first contact. Look for live chat that runs day and night and an email address, then test the chat before paying in: ask how long a withdrawal takes by your method, and see whether the answer is quick and specific.
If a problem comes up, raise it in live chat first, then by email, and keep a copy of each answer with its date. Reply to the casino's questions promptly, because some processes close a complaint when a player goes quiet. The ADR route is closed here, which leaves the casino's own complaint process and its regulator, if one is named.
A GAMSTOP registration is a decision you made for a reason, and it deserves to hold. This site is not a way around it, and no casino listed here should be used to get past it. Talking to someone costs nothing: the GamCare National Gambling Helpline answers on 0808 8020 133 at any hour, and Samaritans are on 116 123, day or night.
If you still choose to play at a casino not on GamStop, set up its tools before the first deposit:
Most UK banking apps, Monzo and Starling among them, offer a gambling block; lifting it takes at least 48 hours. It does not stop crypto deposits, so add blocking software too: Gamban is paid, BetBlocker is free, and both work on your device rather than on one casino account.
These services are free, for you or for someone you are worried about:
Gambling in the UK is for adults: the minimum age is 18.
Sites not on GamStop give you more: more offers after the welcome, more ways to pay, casino and sport under one login. They also take away the UK's guard rails: no GAMSTOP block, no free complaint route and no £5 cap on a slot spin. Only you can say whether the swap is worth it.
If you go ahead, decide what matters most to you – a low minimum withdrawal, light wagering, regular cashback or a sportsbook – and choose the casino whose weak point you mind least; the reviews above show each one's weak spot. Set your limits before you deposit, and re-read the bonus terms just before signing up, because they change.
No. The scheme applies only to operators with a UK Gambling Commission licence, so it does not stop you joining a site outside it. If you registered, add Gamban or BetBlocker and your bank's gambling block, and call GamCare's free line, 0808 8020 133, at any hour.
Usually the account, not always the limits. Every casino reviewed here lets you hold GBP, but some set withdrawal caps and bonus sums in euros.
Anywhere from minutes to about a week. The casino signs off the request first, often within a day; then crypto is fastest and a bank transfer slowest.
Yes, in most cases. Expect photo ID and a proof of address before you are first paid, and sometimes a bank statement. Sending them early means your first payout does not stall.
The multiple and what it applies to. With a £50 deposit and a £50 bonus, 30x the bonus means £1,500 in bets, while 30x the deposit plus the bonus means £3,000. Then check the cap on what the bonus can pay out.
On the regulator's own register. Note the company and licence number from the casino's terms, search for them on the issuer's website, and make sure the entry shows the same company and web address. A logo in the footer proves nothing by itself.
