A hundred operators sit in our library. Forty-seven of them can be scored; fifty-three cannot, and get no number at all rather than a low one. That single ratio is the most important thing on this page, because it sets the limit on what a best online casino UK ranking is able to claim. Behind the forty-seven there are seven scoring components, and one of the seven has never been filled for a single brand in the library, so the most any operator can earn is ten points of a possible eleven. Seventeen brands reach six components. Twenty-six have none filled at all. Thirty publish a coin list we could read and seventy do not; thirty-eight publish a country list and sixty-two do not; fourteen state a withdrawal ceiling and five state a verification threshold. Those are the raw materials. What follows sets out each of them with its number, then says plainly what a ranking built on that much missing data can and cannot be used for.
Seven components, and one nobody scores
150% up to 1.5 BTC, plus 100 free spins
Deposit in BTC, ETH or USDT and the casino adds 150% up to 1.5 BTC along with 100 free spins. The next three deposits are matched at 100%, 50% and 25%.
Claim 100 free spinsThe scoring file records its own weights, and they add up to eleven points rather than ten: licence 2.5, verification clarity 2.0, published restricted list 1.5, coins 1.5, reach 1.5, no verification demanded at sign-up 1.0, and game providers 1.0.
The last of those is marked unscored for the whole library. Not one of the hundred operators has a providers figure, so the maximum available anywhere is ten, and every rated brand is measured out of ten with the eleventh point permanently out of reach. We publish the weight anyway rather than quietly renormalising, because a component nobody can fill is itself a finding about the category.
A brand needs at least three filled components before it gets a rating. Seventeen reach six, which is the ceiling in practice. Sixteen reach five, nine reach four, nine reach three. Then the drop: four have two, nineteen have exactly one, and twenty-six have none.
Three components apart, the weights say what a best online casino UK ranking is really sorting on. The licence line carries more than coins and reach put together, because it is the only claim on an operator’s own pages that can be checked against a third party’s database. Coin breadth is cheap to publish and costs a brand nothing. The full arithmetic, component by component, is on the weights and the three-component floor.
Fifty-three brands with no score, and why
Fifty-three of the hundred carry no rating. Forty-nine of those fail the three-component floor. The other four clear it and are still left unrated, because a licence number returned as revoked is treated as disqualifying rather than as a deduction.
Bets.io is the clearest example. Six of its seven components could be filled, its coin list runs to twelve entries and its country list to forty-two, and its Curaçao Gaming Authority number OGL/2024/1178/0479 comes back from that authority’s certificate portal with the status Revoked against company number 155648. On a weighted average it would score respectably. It gets nothing.
The alternative would be to publish a middling figure for a brand whose licence has been withdrawn, which is the same failure as inventing a verification threshold. A number implies we know something we do not.
The other side of the floor matters just as much. Twenty-one of the hundred have the value none in the field recording how their pages were read, which means nothing could be read at all and every fact about them is null. Thirty-eight were read live and forty-one from an archived copy of the same pages. A best online casino UK table that listed all hundred names in rank order would be ranking twenty-one brands on nothing, and that is the shape most pages in this category take.
Licences: fifty-six current, seven unreturned, five revoked, thirty-two blank
The licence component is the heaviest, so its distribution across the hundred is the backbone of any ranking here.
| Licence status | Brands |
|---|---|
| Number returned as current by a register | 56 |
| Number published but not returned as current | 7 |
| Number returned as revoked | 5 |
| No licence fields at all | 32 |
Two registers are queried, both read on 26 August 2026: the Curaçao Gaming Authority certificate portal, which is indexed by domain, and the Anjouan Gaming Board public register. A null in either means the domain was not found there, which is not the same as saying a brand is unlicensed. It means we did not read it, and the distinction is written into the source file rather than added by us.
Inside the 56, the two series look different in what they hand back. A Curaçao entry typically returns the licence number, a status and a company number — Cloudbet on OGL/2024/328/0599, Active, company 148526; Shuffle on OGL/2024/1337/0628; Metaspins on OGL/2024/1063/0437; Wild.io on OGL/2024/210/0198, company 161858; Playbet.io on OGL/2024/1214/0712, company 161842. An Anjouan entry typically returns a holder and an entry date — Windice under Windice Group Limited from 4 November 2024, DuckDice under Zentari Limitada from 16 September 2025, Wild Fortune under Metlait SRL from 30 September 2025, Rakebit under Nile King Media Ltd from 18 February 2026. Different registers, different fields, and a best online casino UK comparison that prints only the word licensed has thrown all of that away.
Eleven of the hundred state a founding year. The other eighty-nine leave it null, and we leave it null too.
Thirty-eight country lists, twenty-nine naming GB, sixty-two blanks
The second heaviest input into a best online casino UK ordering is the country list. Thirty-eight of the hundred publish one our files could read. Twenty-nine of those thirty-eight name GB. Nine publish a list on which GB does not appear. Sixty-two have an empty cell.
The empty cell is the figure that gets misread most often, so it is worth stating twice: a zero-length list in our data never means an operator accepts every market. It means no list could be read. Sixty-two blanks out of a hundred is a statement about how much of this category publishes nothing on the subject, not a verdict on sixty-two brands.
Among the thirty-eight, length ranges from six entries to 224. A six-entry list names a handful of markets and is a targeted document; a 224-entry list is a near-global exclusion with a short set of permitted markets implied by what it leaves out. Averaging the two, or counting them as one vote each, produces a number that describes nothing. We keep the lengths and read them separately on the page that reads those lists at their own length.
Nine of the thirty-eight publish a list that does not name GB. Two of the nine also publish a coin list, which makes them the only brands in the library where both fields can be read and GB is absent from one of them: Bets.io, whose forty-two entries do not include GB but whose licence comes back revoked, and Cloudbet, whose list has two entries. One usable pair out of a hundred names is the honest measure of how thin this evidence is.
Fourteen ceilings, five thresholds, one shared clause number
Fourteen operators state a withdrawal ceiling. Five state a monetary verification threshold. Eighty-one state neither.
| Threshold | Figure | Clause |
|---|---|---|
| Bitcasino.io | 2,500 EUR | 6.6 |
| Sportsbet.io | 2,500 EUR | 6.6 |
| Livecasino.io | 2,500 EUR | 6.6 |
| Rocketpot | 2,500 USD | 11.4 |
| Empire.io | 2,000 USDT | 5.4 |
Three of the five publish the same figure at the same clause number, which is drafting reuse rather than coincidence: Bitcasino.io and Livecasino.io both publish Curaçao licence OGL/2023/111/0069 under Moon Technologies B.V., and Sportsbet.io publishes OGL/2023/110/0072 under MBet Solutions N.V. Reading those three as three independent data points would triple-count one document.
The ceilings spread across four periods — per transaction, per day, per week, per month — and three currency units, with USDT the only coin among them. Comparing a daily figure with a monthly one without carrying the period is the standard error here, and multiplying a published figure to annualise it produces a number the operator never wrote. We do neither. The conditions that sit alongside those ceilings are set out on the page about how balance terms are worded, and the document clauses themselves on the payout-documents page.
Forty-nine of the hundred have verification wording we could summarise and twenty-seven attach a clause number to it. Three record a position on location masking. So for the majority of the library the answer to when documents are requested is a paragraph with no number and no reference, and a best online casino UK ranking has to weigh that as an absence rather than treat it as reassurance.
Eight licence numbers covering twenty-two of the hundred
Eight licence numbers in the library each appear against more than one brand, covering twenty-two of the hundred names between them.
- Anjouan Gaming Board ALSI-202508056-FI2, holder Novatrix SRL, entry dated 25 August 2025 — Oshi Casino, PlayAmo, Slotum, Winz.io, Bitkingz.
- Curaçao Gaming Authority OGL/2024/1307/0748, holder Scores55 Tech B.V. — 7Bit Casino, KatsuBet, Mirax.
- Curaçao Gaming Authority OGL/2023/103/0067, holder Rabidi N.V. — Betriot, Casinoly, Zet Casino.
- Curaçao Gaming Authority OGL/2024/1798/1048, holder Santeda International B.V. — Rolletto, Goldenbet, Velobet.
- Curaçao Gaming Authority OGL/2024/1267/0760, holder Uno Digital Media B.V. — CryptoLeo, Nine Casino.
- Curaçao Gaming Authority OGL/2023/111/0069, holder Moon Technologies B.V. — Bitcasino.io, Livecasino.io.
- Curaçao Gaming Authority OGL/2024/1800/1049, holder Ryker B.V. — Jackbit, Freshbet.
- Anjouan Gaming Board ALSI-202508047-FI2, holder Sorta Group Limitada — Fairspin, Weiss.
A second overlap sits underneath that one. Nine domains appear in both registers at once, and in every one of the nine the company named on the Anjouan side is not the company named on the Curaçao side: BC.Game, Bets.io, Metaspins, Roobet, Thrill, Thunderpick, TrustDice, Wild.io and Playbet.io. Two registers, one domain, two holders.
We draw no conclusion about ownership from either pattern, because our files do not carry one. What both patterns do establish is narrower and directly relevant: treating two brands that sit under the same licence number as two independent choices is an error, and a best online casino UK table that lists them as separate rows without saying so is presenting one document as several. That is why the the per-brand records underneath the table print the number and the holder rather than the word licensed.
The top of the table, and what best online casino UK can mean
Sorted by score, the library runs Cloudbet and DuckDice at 8.5, Rainbet at 8.4, Wild Fortune at 8.3, Windice at 8.1, Rakebit and Shuffle at 8.0, Metaspins at 7.9, Wild.io at 7.8, then Bitcasino.io, Sportsbet.io, Empire.io and Playbet.io at 7.5.
Nine of those thirteen have six of the seven components filled, which is the practical ceiling; Bitcasino.io, Sportsbet.io and Empire.io reach 7.5 on five, and each of the three has an empty coin cell. None of them is close to ten out of ten, and the gap is made of specific missing things rather than of judgement: no providers component exists anywhere, most of them state no verification threshold, and several reserve document requests at any time without naming a clause or a figure.
Cloudbet is the most complete record in the library and worth reading as the benchmark rather than as a recommendation: forty coins, the longest list anywhere; a two-entry restricted-country list; verification at clause 18.1.1 describing repeatable risk-based document requests; a founding year of 2013, the earliest stated; a location-masking position recorded, one of only three in the hundred; and Curaçao Gaming Authority licence OGL/2024/328/0599 returned Active against company number 148526. Even that record has a null verification threshold and a null providers cell.
So what best online casino UK can mean on this site is narrow and stated: the operator whose own documents and register entries are most completely readable, scored on seven declared components with the weights published. It cannot mean the operator that pays out fastest, because no payout time exists in our files. It cannot mean the cheapest to deposit into, because no network fee exists either. It cannot mean the one that suits a particular reader, because nothing in these files describes a reader. The coin-by-coin cuts of the same hundred names start with the coin-by-coin cut that starts with bitcoin, and the ranked table itself is our list of the best crypto casinos UK readers come here to compare.
