About Us

Sites Not On Gamstop is an independent research site for adults in the UK who want to understand casinos not on GamStop before they sign up. This page explains who we are, how we assess sites, how we earn money and where our knowledge stops. Our current focus is free spins and no deposit offers at these casinos, and what the small print behind them really means.

Facts on this page were last checked on 29 September 2026. Casino terms change often, so treat everything here as a starting point and read the operator's own terms before you register.

What we do and who we write for

We publish reviews and guides on non GamStop casinos: bonuses, wagering requirements, payments, withdrawals, games and sports betting. Our readers are adults aged 18 and over, mostly in the UK, with very different levels of gambling knowledge. We explain terms such as wagering, KYC checks and bonus cashout limits without assuming you already know them.

We do not present gambling as a way to earn money or fix financial problems. It is paid entertainment, and the odds favour the operator.

What "not on GamStop" actually means

GAMSTOP is the national self-exclusion scheme for licensed gambling operators in Great Britain. Sites licensed by the UK Gambling Commission must take part in it. A casino not on GamStop is usually licensed elsewhere, often under an overseas licence such as one issued in Curaçao, and is not part of that scheme.

That has consequences you should weigh up:

• Accepting British players is not the same as being authorised by the UK Gambling Commission to serve them.
• Your GAMSTOP exclusion will not carry over to these sites.
• UK complaint routes and protections may not apply, so disputes can be harder to resolve.
• Deposit limits, loss limits and self-exclusion may exist, but the tools and their quality vary by operator.

If you have registered with GAMSTOP because gambling was causing you harm, we would encourage you to stay excluded. Our responsible gambling page lists support such as GamCare and explains blocking software and other safeguards.

How we assess casinos

We have not staked money on, or withdrawn money from, the casinos we list, and we do not claim to have done so. Our reviews are desk research: we read the operator's published terms, licensing information, payment pages and promotion rules, and we compare them side by side. We look at:

1. Bonus terms: wagering requirements, game contribution, maximum bet while a bonus is active, expiry dates and cashout caps.
2. Free spins and no deposit conditions: which slots they apply to, the value of each spin and any limit on winnings.
3. Payments: minimum deposits, GBP account availability, debit cards, bank transfers, e-wallets, cryptocurrency, fees and currency conversion.
4. Withdrawals: stated processing times, limits, and identity or source-of-funds checks.
5. Games and betting: slots, live dealer tables, software providers, and any sportsbook or esports betting.
6. Licensing, ownership and support: what the operator states, and how you can complain.

We separate three kinds of information: what we could confirm from official sources, what is casino advertising, and what remains unresolved. Where we cannot verify something, we say so.

How the ranking works and how we earn money

We may earn a commission if you register with a casino through a link on this site. That commission does not buy a higher position. The publisher supplies the selection of casinos, and our editorial ratings are our own assessment of published terms. They are not customer review scores.

The casinos we currently feature

The ranked list on our non GamStop casinos guide covers Betmica, Kikibet, Betninja, WinnerIsland, Zombillion, Smash Casino, Nightluck, CoinPoker, Rivo and Daytonaspin. Here is how the leading three stand out on paper, and what to watch.

Betmica

Ranked first with an editorial rating of 10.0. Its advertised welcome offer is 570% up to £5,700 plus 270 free spins. The offer is in pounds, which suits UK readers. The limitation is the size: large percentage matches usually come with higher wagering, so read the wagering requirement, maximum bet and expiry terms before depositing.

Kikibet

Rated 9.9, advertising 350% up to 5,555 £ and 300 free spins. It has the biggest free spin count among our top three. We have no confirmed detail here on which games the spins cover or any cap on their winnings, so check that before you claim it.

Betninja

Also rated 9.9, with a £1,000 bonus and 100 free spins for new players. The headline is simpler than a multi-stage package, which makes it easier to judge. The drawback is fewer spins than the two above. As always, the bonus rules matter more than the headline figure.

Quick comparison of advertised offers

These are advertised offers, not guarantees. Several are in euros or dollars, so you may face currency conversion fees on deposits and withdrawals. Offers usually require a qualifying deposit, so they are not free money, and most carry wagering requirements, time limits and cashout caps. We have not verified each casino's full terms here.

Money, games and betting: what we cover

Payments differ between operators. We check whether a site offers GBP accounts, debit cards, bank transfers, e-wallets, PayPal or cryptocurrency, and we advise you to confirm availability for UK customers on the casino itself rather than assume. Watch for fees, minimum deposits, withdrawal limits and identity or source-of-funds checks, which can delay a payout.

On games, we look at slots, progressive jackpots, live dealer blackjack, roulette and baccarat, software providers and stated return to player figures. Many of these casinos also run sportsbooks, including esports, pre-match and in-play markets, accumulators and cash-out. Sports offers work differently from casino bonuses, with minimum qualifying odds, which we express in decimal odds. Some sites share one wallet between casino and sportsbook.

Eligibility and staying in control

You must be at least 18 to gamble. Casinos will ask you to verify your age and identity, so have ID ready. Only gamble money you can afford to lose, and set deposit and loss limits from the start. If gambling stops being fun, GamCare offers free, confidential support, and GAMSTOP can be used to exclude yourself from licensed GB sites. Our terms and conditions explain how you may use this site.
