About Us

Non Gamstop Casinos is an independent research and comparison site covering casinos not on GamStop, with a particular focus on free spins offers and the wagering terms attached to them. This page explains who writes the site, how we assess the casinos we list, how the site makes money, and — just as important — what we cannot verify and will not claim.

Everything here is written for adults aged 18 or over in Great Britain who are researching offshore-licensed casino sites and want the terms explained in plain English before they commit money.

Why this site exists

GamStop is the free self-exclusion scheme that every casino licensed by the UK Gambling Commission must integrate with. Once you register, licensed GB operators must block your account for the exclusion period you chose — six months, one year or five years — and it cannot be shortened on request.

Casinos not on GamStop sit outside that system because they hold overseas licences rather than a UK Gambling Commission licence. Curaçao is the most common jurisdiction, with Anjouan and Costa Rica also appearing. Accepting British customers is not the same thing as being authorised to serve them, and that distinction matters: if something goes wrong, you are not covered by the Gambling Commission's complaints framework or by UK-specific rules on bonus fairness and advertising.

Readers still search for these sites, and many arrive with no clear picture of what they are giving up. Our job is to set out the offers, the restrictions and the protections accurately — not to talk anyone into or out of anything. If you are currently self-excluded through GamStop, the honest advice is to let the exclusion run and to look at our responsible gambling resources instead.

How we research and rank

We do not gamble with our own money to produce these reviews, and we make no claim to have tested withdrawals, deposits or customer support. What we do is read and record what casinos publish, then check it against independent sources where those exist. Our ratings are editorial judgements from that research — they are not customer review scores and they are not a measure of how likely you are to win.

Each casino on the site is assessed against the same checklist:

1. Licence and ownership. Which regulator is named, which licence number is displayed, which company is stated as the operator, and whether those details are consistent across the site's footer, terms and payments pages.
2. Bonus terms in full. Wagering multiple, whether it applies to bonus only or deposit plus bonus, game contribution rates, maximum bet while a bonus is active, expiry windows and any cap on what you can withdraw from bonus winnings.
3. Free spins detail. How many spins, on which slots, the value per spin, whether spins are released in daily batches, and what wagering applies to the winnings they produce.
4. Payments for British customers. Whether GBP accounts are offered, which deposit and withdrawal methods are actually listed as available to UK players, stated fees and any currency conversion.
5. Withdrawal conditions. Minimum and maximum withdrawal amounts, daily, weekly and monthly caps, stated processing times, and what verification the terms require.
6. Game range and providers. Which studios supply the slots and live tables, whether RTP figures are published, and how deep the live dealer and jackpot sections are.
7. Player protection tools. Deposit limits, loss limits, session reminders, time-outs and self-exclusion at account level.
8. Support and complaints. Contact channels published, languages served, and whether an independent dispute route is named.

Findings are dated. Offshore casinos change bonus terms, payment lists and even ownership without notice, so anything time-sensitive on this site carries the date it was last checked. This page was last fact-checked on 23 September 2026. Where a claim comes from the casino's own marketing rather than a verifiable source, we say so.

How we are funded

Non Gamstop Casinos earns commission when a reader signs up with some of the casinos listed here. That is how the site pays for itself, and you should read every listing with that in mind. Commercial relationships do not buy ranking position, and they do not stop us publishing a drawback. Where a casino pays us nothing, it can still be listed; where one pays well but publishes poor terms, that shows in the write-up.

No bonus on this site is free money. Every welcome offer below requires a deposit of your own funds, carries wagering requirements, and can expire. Full terms are set by the operator, not by us, and they take precedence over any summary here.

What our top-rated listings look like in practice

Three examples from our current ranking, to show the level of detail we work at and the kind of limitation we flag. Full reviews and the wider list sit on our non GamStop casinos comparison.

Betmica — the largest free spins package we currently list

Betmica ranks top on our editorial scale at 10.0, largely because its advertised welcome offer of 570% up to £5,700 plus 270 free spins is stated in pounds sterling, which removes the conversion guesswork that catches out UK players at euro-denominated sites. The spins package is among the biggest we have recorded.

What to check before claiming: a 570% match is a very large bonus balance relative to your deposit, and large matches almost always come with high wagering multiples and a low maximum bet while the bonus is active. Confirm the multiple, the maximum cashout from bonus winnings, and which slots the 270 spins are locked to. Limitation: a headline of this size is realistically only reachable at the top deposit tier, so the figure most players see will be far smaller — and like every casino on this page, Betmica operates outside UK Gambling Commission oversight.

Kikibet — a spins-heavy offer at a lower match rate

Kikibet sits at 9.9 with 350% up to £5,555 and 300 free spins. The lower match percentage alongside a larger spin count makes it a different shape of offer from Betmica: less bonus cash to clear, more spin-generated winnings to wager. For players who mainly want slot spins rather than a huge bonus balance, that trade can be easier to work through.

Limitation: a 300-spin allocation is commonly drip-fed over several days, which means the whole package is only usable if you keep returning inside the expiry window. Check the release schedule and the per-spin value before judging the offer by its headline number.

Betninja — a modest, more readable package

Betninja also rates 9.9, but for the opposite reason to the two above: its £1,000 bonus and 100 free spins for new players is small enough to be realistic. A four-figure ceiling is achievable for a mid-sized deposit, and 100 spins can be cleared without a fortnight of daily logins.

Limitation: the advertised value is a fraction of what the biggest packages promise, so it will not suit anyone shopping on headline size alone. As with all listings here, the published terms are the operator's and should be read in full before you deposit.

How the top four compare on headline terms

Casino	Editorial rating	Advertised welcome offer	Free spins	Currency shown
Betmica	10.0	570% up to £5,700	270	GBP
Kikibet	9.9	350% up to £5,555	300	GBP
Betninja	9.9	£1,000 bonus	100	GBP
WinnerIsland	9.7	Up to €1,000	100	EUR

Others we cover include Zombillion (9.7, 250% up to £4,000 + 200 free spins), Smash Casino (9.7, 600% up to €10,000 slots package), Nightluck (9.6, €6,400 + 280 free spins + 805%), CoinPoker (9.6, 150% up to $2,000), Rivo (9.4, 1000% up to €10,000 + 25% cashback) and Daytonaspin (9.4, 255% up to £4,500 + 255 free spins). Where an offer is quoted in euros or dollars, expect a conversion step on deposit and withdrawal unless the casino confirms a GBP account.

Money in, money out — what we always look at

Bonus size is the easiest thing to advertise and the least useful thing to compare. We give more weight to the cost of taking part and the route your money takes back out.

• Minimum deposits. Often £10 to £20, but a large percentage match may require a higher minimum to unlock the advertised tier.
• Debit cards. Visa and Mastercard are the most widely accepted route for British players. Credit cards are banned for gambling at GB-licensed operators; offshore sites are not bound by that rule, which is a reason for caution rather than convenience.
• E-wallets and prepaid. Skrill, Neteller and prepaid vouchers such as Paysafecard appear frequently. PayPal is rare at non-GamStop casinos because PayPal restricts gambling merchants — never assume it is available; check the cashier before depositing.
• Bank transfer. Usually the slowest option and sometimes the only route for larger withdrawals.
• Cryptocurrency. Common offshore. Fast in principle, but the value of your balance moves with the market and conversion spreads are rarely disclosed clearly.
• Fees and conversion. Check both the casino's stated fee and your bank's non-sterling transaction charge if the account is held in euros or dollars.
• Withdrawal timing and limits. Stated processing times are advertised figures, not results we have measured. Weekly or monthly caps matter far more than headline speed — a £4,000 cashout under a £1,000 weekly limit takes a month.
• KYC and source of funds. Expect to supply ID, proof of address and sometimes evidence of where your money came from. Verifying early, rather than at the point of withdrawal, avoids most delays.

The games and betting markets behind the spins

Free spins are a slots promotion, but the sites carrying them are full casinos. Our reviews look at the whole catalogue: slots across low and high volatility with published RTP where available, progressive jackpot titles, and live dealer rooms streaming blackjack, roulette and baccarat with real croupiers. We note which software providers supply the lobby, because a recognised studio list is one of the few outward signs of a casino's supply arrangements. We also check how the site behaves on a phone, since most play happens there.

Most of these operators run a sportsbook alongside the casino, and it works to different rules. Pre-match and in-play markets, accumulators, bet builders, cash-out and esports are standard; free bet promotions usually carry minimum qualifying odds, often around 1.50 or 2.00 in decimal terms, and a free bet stake is not normally returned with winnings. Where the casino and sportsbook share a single wallet, casino bonus wagering may not be cleared by sports bets at all — worth confirming before you move a balance across.

Eligibility, legality and your protections

You must be 18 or over to gamble in Great Britain. Using an offshore casino from the UK is not a criminal offence for the player, but the operator is not authorised by the UK Gambling Commission, so the consumer protections that come with a GB licence do not apply to your account. In practice that means:

• No recourse to the Gambling Commission if a withdrawal is refused or a bonus term is applied unfairly.
• Dispute resolution depends on whatever the overseas licensing body offers, which varies widely in effectiveness.
• GamStop self-exclusion will not block these sites, because they are not connected to the scheme.
• UK rules on credit card deposits, affordability checks and advertising standards do not bind the operator.

Nothing on this site should be read as a promise that a casino is safe or that a withdrawal will be paid. We describe what is published and what is verifiable; the risk of playing sits with you. If gambling has stopped being entertainment, GamCare offers free, confidential support on 0808 8020 133, and device-level blocking software will restrict access in a way an account-level exclusion cannot. Deposit and loss limits are the most practical tool most players ignore — set them before your first session, not after a bad one.

Who writes this

The site is edited by Niamh McConnell, who researches licensing records, bonus terms and payment documentation for every casino listed and dates the findings. Reader reports feed directly into how the pages are updated: if a casino's terms have changed, or a withdrawal has gone differently from what the site describes, we would rather hear it and correct the page. The full rules covering use of this site are set out in our terms and conditions.

Getting in touch

Corrections, questions about a specific bonus condition, or feedback on a casino you have used are all welcome through our contact page. We do not operate casinos, hold player funds or intervene in disputes on your behalf, but accurate reader information is what keeps these pages worth reading.

If you are deciding where to start: compare the wagering multiple and the maximum cashout before the headline percentage, favour a casino that quotes in pounds if you bank in pounds, and read the free spins clause in full. Take your time — the offers on this page will still be here tomorrow, in one form or another.
