Best Non GamStop Casinos UK - Online Platforms Compared

Commercial disclosure: Casinos Not On Gamstop may earn a commission when you sign up through a link on this page. That relationship never decides how a casino is rated or where it sits in the list below.

What GAMSTOP is and why these sites sit outside it

GAMSTOP is the UK's free self-exclusion scheme. Once a player registers, every casino and betting site holding a UK Gambling Commission licence is required to block that account for the chosen period, usually six months, one year or five years. Non GamStop casinos hold licences from other regulators instead, most commonly Curaçao, so the UK scheme has no technical link into their systems. That's a licensing difference, not a way of getting around anything, and it's worth understanding before you read any further: the checks, protections and complaint routes are different from what a UK-licensed site offers, not absent.

How we rated and ranked these casinos

Every site listed here was reviewed against the same set of checks, and no casino paid to move up the list.

• Licensing — which authority issued the licence and what it actually requires of the operator.
• Bonus value once the terms are applied — wagering multiple, time limit to clear it, and any cap on what you can withdraw.
• Payment methods — the deposit and withdrawal options on offer, and which ones bonuses exclude.
• Game range — the split between slots, table games and live dealer studios, and the software providers behind them.
• Player tools — deposit limits, time-outs and account closure options, since GAMSTOP isn't the only safer-gambling control available.

Casinos worth a closer look

The following mini-reviews cover the highest-rated sites from our list. Each has a genuine reason for its position, and each has at least one limitation worth knowing before you sign up.

Betmica — top-rated for welcome bonus size

Betmica tops the list with a Welcome Offer of 570% up to £5,700 plus 270 free spins, which is the largest headline match on this page by a wide margin. That scale is the reason it's ranked first, but a bonus this size will almost certainly carry a high wagering requirement and a maximum stake while wagering is active — check both figures in the terms before you rely on the full £5,700 being realistically clearable. A large percentage match is only useful if the conditions attached to it are ones you can actually meet.

Kikibet — strong value with a lower entry point

Kikibet's 350% up to £5,555 plus 300 free spins sits just behind Betmica but offers more free spins for a smaller minimum deposit tier in many cases, which suits players who want to test a site without committing a large first deposit. The trade-off is the same as with any high-percentage offer: read the wagering requirement and game contribution table carefully, since slots and table games rarely count the same amount toward clearing a bonus.

Betninja — a flat bonus that's easier to calculate

Betninja offers £1,000 plus 100 free spins to all new players, a flat amount rather than a percentage match. That makes the maths simpler upfront — you know the ceiling immediately rather than working out a match against your deposit. The limitation is that £1,000 is modest next to the percentage-based offers above it, so if bonus size is your main priority, Betninja won't be the pick. It earns its place on assessment quality rather than headline value.

Non GamStop casinos vs UKGC-licensed casinos

How the money works: deposits, withdrawals and costs

Joining a non GamStop casino doesn't cost anything beyond what you choose to deposit and stake. Beyond that, three things determine how the money actually moves:

• Deposit methods — cards and e-wallets are the most widely supported options, and several sites on this list accept Paysafe cards for players who prefer not to use a bank card directly.
• Withdrawal timing — any processing time an operator advertises is a target it sets itself, not a tested result, and it usually depends on how quickly your identity verification is completed.
• Verification — expect to submit ID and proof of address before your first withdrawal rather than at signup. Uploading these early avoids delays later.

Withdrawals typically return to whichever method you deposited with, and most sites set a minimum withdrawal amount alongside maximum limits per transaction or per day.

What you can actually play

Game ranges across non GamStop casinos generally split into the same broad categories:

• Slots — the largest category by volume, from classic three-reel games to feature-heavy video slots with progressive jackpots.
• Table games — blackjack, roulette and baccarat variants, usually with several stake levels.
• Live dealer games — streamed tables with a real dealer, covering the same core games plus game-show style formats.

Bonus wagering contributions typically differ by category — slots usually count in full toward clearing a bonus, while table and live dealer games often contribute a much smaller percentage or nothing at all.

Betting sites not on GamStop

Several operators that run non GamStop casinos also offer a sportsbook alongside it. These betting sites not on GamStop typically cover football, horse racing, tennis and the other major sports, with markets ranging from match winners to in-play betting during an event. If you're weighing up a casino and a sportsbook from the same operator, check whether the welcome bonus is shared or split between the two, since terms often apply differently to casino play and to sports bets.

Legal standing and who can play

Non GamStop casinos operate under licences issued outside the UK, most commonly by the Curaçao gambling authority. That means UK consumer protections tied specifically to a UK Gambling Commission licence — such as mandatory GAMSTOP checks — don't apply, though the overseas regulator has its own licensing conditions and complaints process. Players must be 18 or over. If you have registered with GAMSTOP, that self-exclusion was a decision made for your own protection, and opening an account elsewhere works against the reason you made it.

How to self-exclude from non GamStop casinos

GAMSTOP itself doesn't cover these sites, so self-exclusion has to be arranged directly:

1. Contact the casino's support team and ask for your account to be closed or self-excluded.
2. Some operators offer their own self-exclusion tools or deposit limits within account settings — check before contacting support.
3. Independent of any single site, GamCare's National Gambling Helpline offers free, confidential support and can advise on wider blocking software that covers unlicensed and overseas sites too.

The positives worth weighing up

Alongside the differences above, non GamStop casinos tend to offer a few practical advantages: larger and more frequent welcome bonuses than many UK-capped equivalents, a wider spread of slot providers and titles, fewer restrictions on stake sizes for higher-limit players, and often a faster signup process. None of that removes the need to check licensing and terms carefully, but it's part of why these sites attract attention.
