Terms and Conditions

These terms set out the basis on which you may use Online Casinos at shelleye.org. They explain what this site does, what it does not do, how our commercial relationships work, and who is legally allowed to act on the information published here. By browsing the site or following a link to a casino brand, you accept the terms below. If you do not accept them, please stop using the site.

Last reviewed by our editorial team on 21 September 2026.

What this website is

Online Casinos is an independent comparison and information service covering online casino sites available to players in the United Kingdom, with a particular focus on welcome bonuses, free spins and ongoing promotions. We are a publisher. We do not operate gambling facilities, hold player funds, accept deposits, process withdrawals, issue bonuses or settle bets. Every wager, deposit and account you create exists with the casino operator, not with us.

That distinction matters for practical reasons. If a bonus does not credit, a withdrawal is delayed, or your account is restricted, the operator's customer support and complaints process is the route to resolution — we have no access to your account and cannot intervene in it. You can still tell us about the experience, and we use that feedback when we revisit a review.

Commercial disclosure and how ranking works

Most of the casino brands listed on this site have affiliate arrangements with us. If you click through and register, we may be paid a commission by the operator. You are never charged for this, and it does not change the offer you receive.

Commission does not buy a position. Placement on our lists is decided editorially, using the criteria below, and a brand that pays more does not move up because of it. Where a strong operator has no commercial relationship with us, it can still appear; where a paying partner falls short on the things that matter to bonus players, it can be removed.

The criteria behind our ratings

• Bonus value against its conditions — the headline percentage matters far less than the wagering requirement, the maximum conversion and the game weighting attached to it.
• Clarity of terms — whether the material conditions are stated plainly before you deposit, or buried.
• Game range and software — breadth across slots, table games and live-dealer rooms, and the studios supplying them.
• Banking — the deposit and withdrawal methods offered, stated processing times and any fees or limits.
• Licensing and player protection — regulatory standing, deposit limits, time-outs, self-exclusion and identity checks.
• Mobile and support — how the site behaves on a phone, and how reachable the support team is.

Our ratings are editorial scores produced by our reviewers from published information and research. They are not customer-review averages, not survey results, and not the outcome of our staff depositing or playing. We research and verify; we do not test with real money.

Bonus offers: accuracy, changes and the terms that bind you

Promotions shown on this site are supplied or published by the operators and change frequently — sometimes without notice, and sometimes differently by country, device or traffic source. We make reasonable efforts to keep them current, but the operator's own terms and conditions are the only binding version. Always read them on the casino's site before you deposit.

The conditions below are the ones that most often decide whether a bonus is worth claiming. Check each one against the offer in front of you.

• Wagering requirement — the multiple of bonus (and sometimes deposit) you must stake before a withdrawal is possible.
• Minimum qualifying deposit — below it, nothing credits.
• Maximum bet while wagering — exceeding it can void the balance.
• Game weighting — slots usually contribute in full; table games and live dealer often contribute far less or nothing.
• Expiry — both the window to claim and the window to complete wagering.
• Winnings cap — a limit on what can be converted from bonus or free-spin winnings to cash.
• Free-spin detail — the eligible game, the value per spin, and whether the spins are released in daily tranches.
• Excluded payment methods — some deposit types do not qualify.
• One per person, household, IP address and device — duplicate accounts forfeit bonuses and, frequently, the balance behind them.

New-player bonuses require a real-money deposit and carry risk to your own funds. Nothing on this site should be read as free money or as a likely outcome. A fuller explanation of these mechanics sits on our guide to UK casino bonuses and free spins.

How the listed offers are presented

The offers rendered above are the operators' own headline promotions as published to us, reproduced for comparison. The table restates the main claimable elements so you can weigh them side by side. Every one is subject to the operator's full terms, minimum deposit, wagering and expiry.

Brand	Advertised welcome offer	Editorial rating
Betmica	570% up to £5,700 + 270 free spins	10.0
Kikibet	350% up to £5,555 + 300 free spins	9.9
Betninja	£1,000 bonus + 100 free spins for new players	9.9
WinnerIsland	Up to €1,000 + 100 free spins	9.9
Zombillion	250% up to £4,000 + 200 free spins	9.9
Smash Casino	600% up to €10,000 slots package	9.8
Nightluck	805%, €6,400 + 280 free spins	9.6
CoinPoker	150% up to $2,000	9.6
Rivo	1000% up to €10,000 + 25% cashback	9.6
Daytonaspin	255% up to £4,500 + 255 free spins	9.6

Where an offer is quoted in euros or dollars, your account may be debited and credited in GBP at the operator's conversion rate, and the sterling value of the cap will differ from the figure advertised. Treat currency as a material condition, not a formality.

Three listings and what the terms mean in practice

Betmica tops our list because the headline combination — 570% up to £5,700 with 270 free spins — is the largest sterling-denominated package among the brands we cover, and it is priced in GBP throughout, so the advertised cap is the cap. Reaching anything near £5,700 in matched funds means depositing four figures, which very few readers will do; for a £20 deposit the practical value is the free spins and a modest matched balance. The limitation is arithmetic: the bigger the percentage, the bigger the wagering pool it creates, and a high-multiple bonus of this size is realistically a long-session proposition rather than a quick one.

Kikibet earns its place on spin volume — 300 free spins is the highest count in this group — paired with a 350% match up to £5,555. The lower multiplier is arguably the sensible trade: a smaller bonus relative to deposit is quicker to clear. Against that, large spin allocations are commonly released in daily instalments on a single nominated slot, which narrows where you can play and puts a clock on the whole package. Confirm the release schedule and the per-spin value before you judge the offer.

Betninja is here for readers who prefer a plain number to a percentage. A £1,000 bonus with 100 free spins for all new players is easy to assess and sits in sterling, and the smaller spin count usually means fewer scheduling conditions attached to it. The trade-off is ceiling: if you deposit heavily, several rivals on this page advertise far more headroom, and 100 spins will not stretch a session the way 250 or 300 would. It suits moderate deposits more than large ones.

Each of the remaining brands listed above is covered in our main comparison. No listing on this site is a recommendation that you gamble, or a statement that you will profit.

Money, and what we are not party to

Using Online Casinos costs nothing. There is no subscription, no registration and no fee of any kind for reading our content or following a link. Our revenue comes from operators, as described above.

All financial arrangements — deposits, withdrawals, currency conversion, bonus crediting and any charge applied to a transaction — are between you and the casino. Typical UK deposit and withdrawal methods include debit cards, bank transfer and e-wallets; note that credit cards cannot lawfully be used for online gambling in Great Britain. Processing times, minimum and maximum limits, and any fees differ by operator and by method, and e-wallet deposits are sometimes excluded from bonus eligibility. Verify the specifics in the cashier before you commit funds. We publish no guarantee that a withdrawal will be paid within any stated period; that undertaking is the operator's.

What the sites we cover actually offer

The brands on this page are general online casinos rather than single-product sites, and the terms attached to a bonus often differ by section. In broad terms you will find:

• Slots — the largest category, and usually the only one that contributes 100% toward wagering. Free spins are almost always confined to it.
• Table games — roulette, blackjack, baccarat and poker variants in RNG form, commonly weighted at a fraction of their stake for bonus purposes, or excluded.
• Live-dealer rooms — streamed tables with human croupiers. Frequently excluded from welcome-bonus wagering entirely, or covered by a separate live-casino promotion.
• Instant-win and crash-style titles — smaller sections whose bonus eligibility varies most between operators.

Game libraries are supplied by third-party studios and change without notice. We do not warrant that any particular title, provider or table remains available at a brand we have reviewed.

Other product lines at the same operators

Several of these brands run more than a casino. Sportsbooks, virtual sports, poker rooms and bingo appear alongside the slots lobby at many UK-facing sites, and CoinPoker is poker-led by design. Those verticals sit under their own terms: a sportsbook promotion is typically governed by minimum odds and a turnover requirement rather than a slots wagering multiple, poker bonuses often release incrementally against rake generated, and casino wagering rarely counts toward a sports offer or vice versa. If you intend to use both sides of an account, read both sets of rules — assuming they are interchangeable is one of the more expensive mistakes a player can make.

Eligibility, legal standing and your obligations

This site is intended for adults aged 18 or over who are legally permitted to gamble where they live. Online gambling offered to consumers in Great Britain is a regulated activity, overseen by the Gambling Commission, and reputable operators serving this market are licensed accordingly. We do not assert the licensing status of any individual brand in these terms; confirm it in the operator's site footer and, if you want certainty, check the regulator's public register before depositing.

Your obligations when you use the site and act on it:

1. Be 18 or over and gambling lawfully in your jurisdiction.
2. Register in your own name, with accurate details, and hold one account per operator.
3. Complete identity and source-of-funds checks when asked — verification is a legal requirement, not an obstruction, and delays at withdrawal usually trace back to it.
4. Read the operator's full bonus terms before depositing to claim an offer.
5. Stake only money you can afford to lose, and use deposit limits, reality checks, time-outs and self-exclusion where they help. Our responsible gambling page sets out the tools and the free UK support services.

If you have self-excluded through GAMSTOP or an operator scheme, do not attempt to register with the brands listed here.

Accuracy, liability and intellectual property

We research the information we publish and correct errors when we find them or when they are reported. Even so, the site is provided on an "as is" basis. Offers, terms, game ranges, payment methods and licensing arrangements change, and there will be moments when a page lags behind reality. We give no warranty that content is complete, current or error-free, and nothing here is legal, financial or tax advice.

To the extent permitted by law, Online Casinos accepts no liability for gambling losses, for any loss arising from reliance on information published here, or for your dealings with a third-party operator. Links to casino sites are provided for convenience; we do not control those sites and are not responsible for their content, terms or conduct.

Text, reviews, ratings and page layouts on shelleye.org are our property or used under licence. You may quote short extracts with clear attribution and a link. Systematic copying, scraping or republication is not permitted. Brand names and logos belong to their respective owners and appear for identification only.

Changes, governing law and contact

We may amend these terms as the site, the market or the law changes. The current version is always the one published here, with the review date shown near the top. Continued use after a change means you accept the revised terms. These terms are governed by the laws of England and Wales.

Questions about this page, a correction to a review, or a complaint about our content can be sent through our editorial team's about page or the contact form. Complaints about an operator should go to that operator first, then to its alternative dispute resolution provider — the route will be named in the casino's own terms.
