About Us

Sites Not On Gamstop is an independent research site for adults in the UK who want to understand casinos that operate outside GamStop before they sign up. We explain how bonuses, payments, withdrawals, licensing and player protections work, so you can judge an offer on its terms rather than its headline.

This page covers what we do, how we rate casinos, how we earn money, and where our limits are. It is written for readers with any level of gambling knowledge, so we explain terms as we go.

What this site is for

Non GamStop casinos are online casinos that are not part of the UK's self-exclusion scheme. That is a legal and practical distinction, not a quality label. Some readers are researching these sites out of curiosity about bonus size or game choice. Others have registered with GamStop and are considering whether to look elsewhere. We cover both situations honestly, and we say plainly where the risks sit.

Our main list is on the page for non GamStop casinos and online casinos for UK players. This page explains the thinking behind it.

The casinos we currently feature

The publisher supplies our casino selections. At the time of the last fact-check (29 September 2026) the ranked list includes Betmica, Kikibet, Betninja, WinnerIsland, Zombillion, Smash Casino, Nightluck, CoinPoker, Rivo and Daytonaspin. The ratings shown are our editorial ratings. They are not customer-review scores and are not based on player feedback.

Here is how we approach the top three.

Betmica

Betmica is 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 casino advertising, and we have not tested it. Bonuses of this size normally carry wagering requirements, maximum bet rules, expiry dates and cashout caps, so read the bonus terms before you deposit. The main limitation is that a large headline figure tells you little until you have checked those conditions. We have not verified how they work in practice.

Kikibet

Kikibet sits second at 9.9. It advertises 350% up to 5,555 £ and 300 free spins. It stands out for the free spin count, but free spins usually come with their own wagering and often a fixed stake per spin. The limitation is that the offer wording does not tell us the qualifying deposit or how long the spins last, so confirm both on the casino's own terms page.

Betninja

Betninja is third at 9.8, advertising a £1,000 bonus and 100 free spins for new players. Its offer is stated in pounds, which makes it simpler to compare for a UK reader, though we have not confirmed whether accounts are held in GBP. The limitation is the same as elsewhere: the terms behind "all new players" are not spelled out in the advertising, so check eligibility and wagering first.

Several other options advertise in euros or dollars. If you fund an account in pounds, currency conversion fees may apply, and you should check for them.

How we assess a casino

We have not deposited, played or withdrawn money at these casinos, and we do not claim to. Our ratings come from research and document review, and we mark what is confirmed, what is advertising, and what remains unresolved. We look at:

• Licensing and ownership – which regulator or overseas licence is stated, and whether the operator is named. We never treat accepting British customers as the same as being authorised by the UK Gambling Commission.
• Bonus terms – wagering requirements, game contribution, maximum bet, expiry and cashout limits.
• Payments – deposit methods, minimum deposits, fees, currency handling and stated withdrawal limits.
• Withdrawals and verification – processing times as advertised, KYC and identity checks, and how disputes are handled.
• Games and betting – slots, live dealer tables, sports and esports betting where offered.
• Support and complaints – contact channels and the route for escalating a complaint.
• Player protection tools – deposit and loss limits, self-exclusion and cooling-off options.

Where a casino gives no clear answer on one of these, we say so instead of guessing. Advertised speeds and limits are reported as advertised, not as tested results.

How we make money, and what it doesn't affect

We may earn commission if you follow a link and register with a casino. That commission does not buy position. Ratings and rankings are not sold, and a casino cannot pay to be placed higher. Even so, you should know that our list is supplied by the publisher and that a commercial relationship exists. We suggest you weigh our advice with that in mind.

What we do not do

• We never describe a casino as completely safe, or promise withdrawals or winnings.
• We do not present gambling as a source of income or a way out of money problems.
• We do not name or compare ourselves with other publishers.
• We do not invent details. If a fact is missing, we leave it out.

The risks you should know about

GamStop is the national self-exclusion scheme for licensed gambling in Great Britain. Casinos outside it are usually licensed elsewhere, and UK Gambling Commission protections and complaint routes generally do not apply to them. If a dispute arises, you may have fewer options. If you have excluded yourself because gambling was causing harm, please think carefully before using sites outside the scheme.

Support is available. GamCare runs a free helpline and chat service, and blocking software can help you restrict gambling sites on your devices. Our responsible gambling page explains limits, self-exclusion and where to get help. You must be 18 or over to gamble.

Get in touch or read the small print

If you spot an error, an out-of-date offer or a term we have misread, tell us through the contact page. We will check it and correct it where needed. Our terms and conditions set out how you may use this site.

A sensible next step is to read the casino's own bonus and payment terms alongside our summaries, then decide whether the offer suits you at all. Walking away is always a fine choice.
