About Us
Who We Are and What We Do
Online Casinos is an independent comparison site dedicated to researching and reviewing online casinos that operate outside the GamStop self-exclusion scheme. We cover the full landscape of sites not on GamStop that accept players in Great Britain — examining welcome offers, game libraries, payment options, licensing and the overall player experience — so that readers can make informed decisions without having to dig through dozens of individual sites themselves.
We do not operate any casino, accept wagers or hold player funds. Our role is research and editorial: we review, we compare, we publish, and we update when things change.
Why We Cover Casinos Outside GamStop
GamStop is a free self-exclusion service that allows UK-based players to restrict their access to UKGC-licensed gambling sites. It is a valuable tool, and we support anyone who chooses to use it. At the same time, a range of internationally licensed casinos operate lawfully and accept GB players who have not registered with GamStop, or whose GamStop period has expired. These sites are not illegal to access from Great Britain, and they attract a substantial audience that deserves honest, accurate information about them.
Our purpose is to provide exactly that: clear, factual coverage of the sites that exist in this space, alongside a frank account of how they compare to UKGC-licensed alternatives. We do not encourage anyone to circumvent a self-exclusion decision they have made. Readers who have concerns about their gambling habits are encouraged to visit our responsible gambling guidance before going further.
All content on this site is intended for adults aged 18 and over.
How We Research and Rank
Every casino listed on Online Casinos has been reviewed against a consistent set of criteria. We do not simply repost operator marketing copy or accept ranking positions in exchange for payment. Commercial relationships — including affiliate commissions we may earn if a reader visits a listed site — do not determine where a casino appears in our rankings. Position is set editorially, based on the factors below.
- Licensing and player protection: We check which regulatory body has licensed the operator, what complaint procedures exist, and whether the site carries tools such as deposit limits or self-exclusion options of its own.
- Welcome offer terms: Headline bonus figures are only part of the picture. We review wagering requirements, game contribution rates, time limits and maximum withdrawal caps before we describe any offer.
- Game range: We look at the breadth of slots, table games and live-dealer rooms on offer, and at the software providers behind them.
- Payment methods: We verify which deposit and withdrawal methods are available to GB players, and what the associated limits, fees and processing times are.
- Site usability and mobile experience: We assess how the casino performs across devices.
- Support availability: We check what contact channels exist and the hours they operate.
Our editorial ratings reflect all of these factors together. They are not customer review scores and should not be read as such.
The Casinos We Currently Feature
The sites on our main non GamStop casinos list are reviewed individually and updated as their offers and conditions change. Here is a brief account of the top-ranked options and what distinguishes each of them.
Betmica — Rated 9.9
Betmica holds the top position in our current rankings. Its welcome offer of a 570% match up to £5,700 plus 270 free spins is among the largest we have seen expressed in GBP terms, which makes it immediately relevant to British players. Beyond the headline figure, we found the site's game selection to be broad, with a strong representation of slots from recognised software studios. Betmica is not UKGC-licensed, so players should note that the consumer protections available through the UK Gambling Commission do not apply here — understanding what recourse exists under the site's own licensing jurisdiction is an important step before depositing.
Kikibet — Rated 9.8
Kikibet ranked second, supported by a welcome package of 350% up to £5,555 and 300 free spins — again quoted in GBP, which simplifies the experience for UK-based players. The free spin count is notably high, making it particularly well-suited to players who prefer slots. As with all sites in this category, Kikibet operates outside UKGC oversight; players should review the terms attached to the bonus carefully, particularly any wagering requirements, before committing funds.
Betninja — Rated 9.7
Betninja rounds out the top three with a straightforward offer: a £1,000 bonus and 100 free spins for new players. The GBP denomination again avoids currency conversion friction for GB players. What distinguishes Betninja in our review is the clarity of its offer structure — the bonus is described in accessible terms, which is not always the case in this sector. That said, the 100 free spin allocation is more modest than some competitors, and players who prioritise free spin volume may find Kikibet or Betmica a closer fit.
Other Reviewed Options
Further down our rankings, WinnerIsland (rated 9.6), Rivo (9.8), Smash Casino (9.9), Zombillion (9.5), Daytonaspin (9.1), Gambiva (9.3) and Nightluck (9.1) have all been reviewed using the same criteria. Some of these sites denominate their offers in euros rather than GBP — worth bearing in mind if you prefer to avoid conversion. Full details for each are available on the main comparison page.
Non GamStop Casinos vs UKGC-Licensed Sites
| Factor | Non GamStop Casinos | UKGC-Licensed Casinos |
|---|---|---|
| GamStop integration | No — operate independently | Yes — mandatory |
| Regulatory oversight | International licence (e.g. Curaçao) | UK Gambling Commission |
| Consumer redress | Via operator or international regulator | UKGC complaints process |
| Welcome offer size | Often larger headline figures | Typically more restricted |
| GBP banking | Varies by site | Standard |
| Responsible gambling tools | Varies by operator | Mandatory minimum set |
Neither column is automatically better. The right choice depends on a reader's circumstances, their familiarity with the regulatory differences, and their own approach to managing their play.
Commercial Transparency
Online Casinos may earn a commission when a reader follows a link to a listed casino and registers an account. This is standard practice for comparison sites and does not influence the order in which casinos appear, the ratings we assign, or the limitations we highlight. We publish drawbacks for every site we cover, including the highest-ranked options.
If you have a question about how a specific casino was assessed, or want to flag a factual error, you are welcome to contact us directly. We review and update our content regularly to reflect current offers and conditions.
Responsible Play
We include responsible gambling information on this site because we think it matters, not because it is a box to tick. If gambling is causing you concern — whether at a GamStop-registered site or elsewhere — our responsible gambling page sets out the free support services available in Great Britain and explains the self-exclusion options that exist at non GamStop casinos too. Many of the operators we cover offer their own deposit limits and cooling-off periods, independent of GamStop.
