Contact Us
This page tells you how to reach the editorial team behind Online Casinos, what sort of questions we can actually answer, and where to go instead when your issue sits with a casino rather than with us. We research and rank UK casino sites and their bonus offers — we are not an operator, so we cannot see your account, release a withdrawal or unlock a bonus.
How to reach the editorial team
The quickest route is email: [email protected]. We read everything that arrives and aim to reply to genuine reader enquiries, though we cannot promise a response time and we do not run a phone line or live chat.
To save a round of back-and-forth, please include:
- The brand you are asking about, spelled as it appears on our pages — for example Betmica, Kikibet or Betninja.
- The page you were reading, so we can check the exact wording you saw.
- What you expected and what you found, particularly if a bonus percentage, spin count or condition looks wrong.
- Screenshots of terms pages where you have them. They are the fastest way for us to verify a change.
Please do not send us passwords, card numbers, full bank details, copies of your ID or anything else you would not want in an email inbox. We never need them, and we will not ask.
What we can help with
- Corrections to a review, rating, bonus figure or terms summary.
- Explaining how a wagering requirement, spin value or maximum bet rule works in general terms.
- Questions about how we compare and order the sites we cover.
- Reader feedback on a brand we list, which feeds into our next review pass.
- Partnership, advertising and media enquiries.
What we cannot help with
- Account verification, closure, locked balances or self-exclusion at a casino — only the operator can act on those.
- Withdrawals, chargebacks or missing deposits.
- Manually crediting a bonus or free spins.
- Complaints we could formally adjudicate. We have no standing to rule on a dispute between you and a licensee.
If your issue is one of the above, contact the casino's own support first, in writing. If you get nowhere, the operator must point you to a free alternative dispute resolution service, and you can raise licensing concerns with the Gambling Commission.
Commercial relationships, stated plainly
Some links on this site are commercial, and Online Casinos may earn a commission when a reader opens an account through one. That arrangement pays for the research; it does not buy a position, a rating or a kind sentence. If you believe a review reads as though it were written to order, say so in an email and tell us which line gave you that impression — that is exactly the sort of message we want.
Reporting a problem with a bonus offer
Bonus terms change more often than anything else we publish, which is why most correction emails concern them. The three below are the offers readers ask about most, with the conditions that tend to cause confusion. Each is a headline advertised figure, not a sum you receive in cash.
Betmica — our top-rated listing
Betmica sits at the head of our table with an editorial rating of 10.0, largely because its advertised welcome offer of 570% up to £5,700 plus 270 free spins is the largest headline package among the sites we cover, and it is presented in sterling rather than converted from euros. That matters for readers who want to know what they are actually being offered without an exchange-rate step.
The assessment to make before you email us about it: a percentage that size only reaches its cap with a substantial qualifying deposit, and the spins usually arrive in tranches rather than all at once. Limitation: a very large multiplier normally travels with a proportionally large wagering requirement and a low maximum bet while the bonus is active, and those two rules together decide whether the offer is worth taking. Check the deposit needed to hit the cap, the wagering multiple and the expiry window on the operator's own terms page before you commit.
Kikibet — sterling-facing package
Kikibet is on this page because its 350% up to £5,555 with 300 free spins gives the highest spin count in our upper tier, at an editorial rating of 9.9. For a reader whose interest is spins rather than bonus balance, that is the relevant number.
Limitation: free spins are typically restricted to named slots, carry a fixed stake per spin, and often cap what winnings from them convert to real money. A high spin count with a low per-spin value can be worth less than a smaller batch on a better game. If you find those restrictions differ from what we have published, that is a correction we will make.
Betninja — the simpler alternative
Betninja earns its place for the opposite reason to the two above: a flat £1,000 bonus and 100 free spins for all new players, rated 9.9, with no headline percentage to decode. Readers who have been caught out by a multiplier they could not realistically max out often find a fixed figure easier to judge.
Limitation: a smaller ceiling means less headroom if you deposit larger amounts, and "all new players" still depends on your country, payment method and whether you have held an account with the brand or its sister sites before. Excluded payment methods — commonly certain e-wallets — are the single most frequent reason a welcome bonus fails to credit.
Where the rest of our list sits
These are the advertised headline offers and our editorial ratings for the other brands we cover, for reference when you write to us about one of them. Ratings are our own judgement, not customer review scores.
| Brand | Advertised welcome offer | Editorial rating |
|---|---|---|
| WinnerIsland | Welcome bonus up to €1,000 + 100 free spins | 9.9 |
| Zombillion | Welcome pack 250% up to £4,000 + 200 free spins | 9.9 |
| Smash Casino | 600% up to €10,000 slots welcome package | 9.8 |
| Nightluck | €6,400 + 280 free spins + 805% | 9.6 |
| CoinPoker | 150% up to $2,000 | 9.6 |
| Rivo | Slots welcome package: 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 deposit and any winnings are converted at the operator's rate, and your bank or card issuer may add its own charge. Ask us to clarify a conversion and we will tell you what the operator publishes; we will not estimate a rate.
Questions about costs, deposits and payouts
We get a steady stream of email about money, so here is the general picture, with the caveat that exact limits and fees are set by each operator and each payment provider — not by us.
- Cost to take part: reading this site costs nothing. Playing costs whatever you deposit, and a deposit is required to qualify for every welcome package listed above. None of these offers is free money.
- Paying in: UK players are usually offered debit cards, bank transfer and e-wallets; some brands also take prepaid vouchers or cryptocurrency. Credit cards cannot be used for online gambling in Great Britain.
- Getting paid out: most operators return funds to the method you deposited with. Cards and e-wallets are typically the quicker routes, bank transfer the slower one, and every withdrawal usually passes an internal review period first.
- Fees and limits: operators commonly apply minimum and maximum withdrawal amounts, monthly caps and, on some methods, a processing fee. Currency conversion is the hidden cost on euro- and dollar-denominated offers.
- Verification: expect to supply proof of identity, address and sometimes source of funds before a first withdrawal. Uploading documents early is the simplest way to avoid a delay.
If a timing or fee figure on our pages no longer matches what an operator publishes, send us the discrepancy and we will re-check it.
What we actually cover, so you email the right place
Our reviews assess the game library as well as the bonus. Broadly, the sites on this page offer:
- Slots — the bulk of most libraries, and the category welcome spins are almost always tied to.
- Table games — roulette, blackjack, baccarat and poker variants, usually the categories that count least towards wagering, or not at all.
- Live dealer rooms — real croupiers streamed in real time, with higher minimum stakes and frequent exclusion from bonus play.
- Game shows and instant-win titles — wheel and quiz formats sitting between slots and live tables.
- Jackpot games — progressive pools, often with their own maximum-bet rules while a bonus is active.
Several of these operators also run product lines beyond the casino: sportsbooks and in-play betting, virtual sports, bingo, and in CoinPoker's case a poker room where you play other people rather than the house. Those sections usually have separate promotions, separate wagering rules and, in the case of sports betting, odds-based minimums that casino bonuses do not use. Ask us about the casino side and we can help; ask about a specific football market and we will point you to the operator.
Playing online rather than in a venue
Readers often ask why we cover online play at all. The practical advantages are straightforward: far wider game choice than any high-street venue can hold, lower minimum stakes, welcome bonuses and free spins that simply have no land-based equivalent, published RTP figures you can check before you play, and built-in tools — deposit limits, time-outs, reality checks and self-exclusion — that are available at the tap of a screen rather than at a counter. You can also play from home, at your own pace, in sterling, without travel.
Licensing, eligibility and where to escalate
You must be at least 18 to gamble in Great Britain. Operators serving British customers are expected to hold a licence from the UK Gambling Commission, which brings obligations on age and identity verification, fair terms, segregation of customer funds and access to free dispute resolution. Some brands available to UK residents are licensed elsewhere — that is the case for sites operating outside the GamStop scheme — and the protections differ, so checking the licensing footer before you register is worth the thirty seconds it takes. We state what an operator publishes about its licence and claim nothing beyond that.
Your own obligations are short: register in your real name, use payment methods in your own name, complete verification honestly, and treat every deposit as money you can afford to lose. If gambling has stopped being entertainment, our responsible gambling guidance lists the free UK support services and the blocking and self-exclusion tools worth setting up today.
Complaints escalate in this order: the operator's support team, then its complaints procedure in writing, then the alternative dispute resolution provider named in its terms, then the Gambling Commission for licensing and conduct concerns. We are none of those bodies, and an email to us does not start a clock on any of them.
How we form the judgements you might want to challenge
Every brand on this site is researched and reviewed rather than played. We read the published terms, the licensing statements, the banking pages and the game categories, then rate on the things that decide a bonus's real value: the size and currency of the headline offer, the wagering multiple, per-spin value and game restrictions, the clarity of the terms, deposit and withdrawal options relevant to UK players, mobile usability and the visibility of player-protection tools. Commission never buys a position. Our facts were last checked on 21 September 2026 by Emily Foster, and you can read more about the people and the process on our about page; the rules governing use of the site are set out in our terms.
Before you write to us
If your question is about an account, a payment or a locked bonus, the operator is the only party who can resolve it — go there first, in writing, and keep the thread. If your question is about something we published, or you have spotted an offer that has changed, email [email protected] with the brand, the page and what you saw. Reader corrections are the main reason our bonus pages stay accurate, and we would rather hear about a mistake than leave it sitting there.
