About Us
Sites Not On Gamstop is an independent review and comparison platform built for UK adults who are looking for European online casinos that operate outside the Gamstop self-exclusion register. We research, verify and rank these sites so you can assess your options clearly before you commit any money.
We are not a casino, and we do not take wagers. Our role is to gather the facts about each platform — its licensing, game range, bonuses, payment methods and player protections — and present them honestly, including the parts that are less flattering.
What We Do and Why
Gamstop is a free UK self-exclusion scheme that allows players to restrict access to UKGC-licensed gambling sites. Casinos that are not registered with Gamstop are typically licensed in other jurisdictions — most commonly Curaçao — and are therefore outside the scope of that scheme. They are not illegal to access from the UK, and many operate legitimate, regulated businesses serving players across Europe.
The market for these sites has grown significantly, and with that growth has come a wide variation in quality. Some platforms offer generous bonuses, broad game libraries and reliable payouts. Others fall short on player protections, transparency or basic fairness. Our job is to tell those apart.
We focus on European casinos because that is where the most reputable non-Gamstop operators are concentrated — platforms serving players across multiple countries under recognised international licences, with genuine accountability to their regulators.
Our Editorial Independence
Sites Not On Gamstop earns revenue through affiliate partnerships. When you follow a link from this site and register with a casino, we may receive a commission. That commercial relationship does not determine how we rank or rate any operator. Casinos cannot purchase a higher position, and our reviews reflect our honest research regardless of whether a site pays us anything at all.
We flag weaknesses for every option we cover — including the highest-rated ones. A review that reads as unqualified praise is not useful to you, and it would not be honest.
How We Research and Rank Casinos
Every casino listed on Sites Not On Gamstop goes through the same research process. No operator is given a shortcut, and no element is skipped because a site has a large welcome bonus or a recognisable name. Here is what we look at:
- Licensing and regulation — We confirm which authority has issued the operating licence, what obligations that places on the casino, and whether the licence is currently active. Most non-Gamstop casinos we cover hold a Curaçao licence.
- Bonus terms — We read the full conditions attached to welcome offers, not just the headline figures. Wagering requirements, game contribution rates, time limits, maximum bet rules and cashout caps all factor into our assessment.
- Game range — We review the breadth of the library across slots, table games, live-dealer titles and any sports or speciality betting available. We check which software studios supply the games and whether the catalogue is genuinely varied or padded with duplicates.
- Payment options — We verify which deposit and withdrawal methods are accepted, what fees apply, what the minimum and maximum transaction limits are, and how long withdrawals typically take.
- Player protections — Even outside Gamstop, responsible operators offer tools such as deposit limits, cool-off periods and self-exclusion. We note what each casino provides and what it does not.
- Overall transparency — We look at how clearly the casino presents its terms, how accessible its support is, and whether its ownership and licensing information is easy to find.
Our editorial ratings reflect the outcome of this process. A score is not a composite of only the positive factors — limitations weigh against the final number just as strengths push it up.

A Closer Look at Our Top-Rated Platforms
Betmica — Our Highest-Rated Pick
Betmica earns its top position primarily because of the breadth and balance of what it offers: a large game library spanning slots, live casino and table titles, a welcome package of 570% up to £5,700 plus 270 free spins that is among the more competitive starting points in this market, and payment flexibility that covers several methods popular with UK players. Its licensing under a recognised international framework gives it more accountability than many offshore alternatives.
The limitation worth noting is that bonus wagering requirements need to be read carefully before claiming — the headline percentage is generous, but the conditions attached to clearing the bonus affect how much practical value it delivers.
Smash Casino — Strong on Slots Volume
Smash Casino is built with slots players in mind. Its 600% up to €10,000 slots welcome package is specifically structured for that audience, and the platform backs it with a wide catalogue of titles from multiple software studios. For players whose primary interest is spinning reels across a variety of themes and mechanics, Smash Casino offers one of the more tailored environments in our current list.
The trade-off is that players whose main interest lies in live dealer games or sports betting will find the slots-forward focus less useful. The welcome offer is also denominated in euros, which means GBP amounts are subject to conversion.
Kikibet — Consistent Across Categories
Kikibet rates highly because it does not concentrate its strengths in one area. The welcome offer of 350% up to £5,555 plus 300 free spins is structured in GBP, which removes currency conversion friction for UK players, and the platform covers slots, table games and live casino with enough depth in each category to suit a mixed playing style.
One genuine limitation is that Kikibet is a newer entrant compared to some longer-established European casino brands, which means its long-term track record on payouts and dispute resolution is shorter. Players who weight proven history heavily may want to factor that in.
Legal Standing and Who May Play
Accessing a casino that is not registered with Gamstop is not illegal for UK adults. These platforms operate under licences issued in other jurisdictions — Curaçao is the most common among the casinos we review — and serve players across multiple European countries. Because they hold no UKGC licence, they are not subject to UK Gambling Commission rules, which means certain UK-specific player protections do not apply automatically.
What this means in practice: affordability checks, the UKGC's advertising standards, and mandatory Gamstop integration do not apply to these sites. Some offer voluntary player protection tools; others do not. Our reviews note what each casino provides in this area.
You must be 18 or older to register and play at any casino featured on this site. This applies regardless of where the casino is licensed.
