About Us

Online Casinos is an independent comparison site for UK players who want their winnings paid out quickly and without fuss. This page explains who we are, how we build our rankings, where our money comes from, and what you can reasonably expect from the casino sites we list — including the parts we cannot verify.

We are not an operator. We do not take deposits, hold player funds or run games. What we publish is desk research: licence checks, published payout policies, bonus terms read line by line, and the banking pages of every brand we cover. Where a detail is not published, we say so rather than filling the gap with a guess.

Why withdrawal speed drives everything we do

Plenty of comparison sites rank on bonus size alone. We think that gets the priorities backwards. A 500% match is worth very little if the cash it produces sits in pending review for five working days, or if the brand caps daily withdrawals below the amount you are trying to move. So the questions we ask first are the payout questions:

• How long does the operator hold a withdrawal before it is approved?
• Is verification done at signup, or only when you first try to cash out?
• Are there daily, weekly or monthly withdrawal ceilings, and do they change by payment method?
• Does the site charge for withdrawals, or apply a minimum below which you cannot cash out at all?
• Can a pending withdrawal be reversed back into the balance — and how easy is that to do by accident?

Bonus generosity still matters, but it sits underneath payout behaviour in our ordering. You will see that reflected in the table below and in the write-ups that follow.

How we rate and rank casino sites

Every brand goes through the same checks, in the same order. Our ratings are editorial scores produced by our team — they are not customer review averages and they are not supplied by the operators.

1. Licensing and consumer protection — we confirm what regulatory status a brand publishes, and whether UK-facing protections such as GAMSTOP self-exclusion apply.
2. Cashout terms — published processing windows, limits, fees and verification policy.
3. Bonus conditions — wagering multiplier, what it applies to, game weighting, maximum bet while wagering, expiry, and any cap on converted winnings.
4. Game range — slots, RNG table games, live dealer studios, jackpot titles and the providers behind them.
5. Banking options — the deposit and withdrawal methods actually offered to UK players and their stated timings.
6. Mobile and support — whether the site works properly in a phone browser or app, and how you reach a human.

Scores are reviewed when terms change. The date at the top of this page reflects our most recent check.

How we make money, and what it does not buy

Online Casinos earns commission when a reader opens an account through one of our links. That is the whole business model, and it is worth being blunt about it: the casinos we list are commercial partners. What commission does not do is decide order. No operator can buy a higher position, edit a rating, or have a drawback removed. If a brand's withdrawal limits are restrictive or its wagering terms are heavy, we write that down next to the offer.

Bonus figures quoted anywhere on this site are the operator's own advertised headline. They are conditional, they change without notice, and the operator's own terms and conditions are always the version that counts. Read them before you deposit.

How the leading brands compare

All offers are for new accounts, subject to minimum deposit, wagering and expiry conditions set by each operator. Where a bonus is advertised in euros or dollars, your balance and any conversion are handled by the casino — check the rate and whether your card issuer adds a foreign transaction fee.

Three brands, and what we actually think of them

Betmica — top of our list, biggest headline number

Betmica sits first because it pairs the largest advertised package on our list with a slots-first library that is easy to navigate on a phone. The 570% up to £5,700 plus 270 free spins offer applies to new accounts only and is released against a qualifying deposit; the percentage is spread across staged deposits rather than granted in one lump, which is normal for packages of this size. The limitation is inherent to the format: a match this large carries a correspondingly large wagering total, and the practical route to clearing it is sustained low-stake slot play rather than a few big spins. If your priority is withdrawing quickly, consider depositing without the bonus — most sites allow it, and an unbonused balance is not locked behind playthrough.

Kikibet — strong free-spin allocation, conditions worth reading twice

Kikibet earns its place on the volume of free spins attached to the welcome package: 300 spins alongside a 350% match up to £5,555. Spins are typically drip-fed over several days and restricted to nominated titles, so the headline count is not something you receive in one go. The draw here is breadth of slot content and a clean account area. The drawback is that spin winnings on offers structured this way usually carry their own wagering requirement and a cap on what can be converted to cash — so treat the 300 spins as entertainment value rather than an expected payout, and check the maximum bet permitted while any bonus funds are active.

Betninja — the simplest terms of the three

Betninja is the one we point newer players towards. The £1,000 bonus and 100 free spins for all new players is a flat, easily understood offer rather than a multi-tier percentage package, which makes the wagering total easier to calculate before you commit. For anyone whose main concern is getting money out again, a smaller, cleaner bonus is often the better trade. The limitation is that the ceiling is lower than the headline figures elsewhere on this page, and higher-stakes players may find the promotional calendar after the welcome offer less generous than at the larger brands.

What you can play

The sites we cover are predominantly slots-led, but the catalogues split into recognisable categories:

• Video slots — the bulk of every library, from low-volatility classics to high-variance releases with bonus-buy features where permitted.
• Jackpot games — progressive and fixed-pot titles. Worth noting that jackpot wins are often paid in instalments rather than a single transfer.
• RNG table games — blackjack, roulette, baccarat and casino poker variants played against software.
• Live dealer rooms — streamed tables with human croupiers, plus game-show formats. These usually contribute little or nothing towards bonus wagering, so check weighting before playing them with bonus funds.
• Specialities — scratchcards, bingo rooms, crash and instant-win titles at some brands.

Game selection comes from third-party studios rather than the casino itself, which is why you will recognise the same titles across different sites. We do not publish game counts unless an operator states them, because those figures move constantly.

The other things these operators run

Most of the brands on this list are not casino-only. Sportsbooks sit alongside the casino at several of them, with football, tennis, racing and in-play markets sharing a single wallet — though bonus funds are almost always ring-fenced to the product they were issued for. Virtual sports and esports markets appear at some. CoinPoker's emphasis is poker: cash games and tournaments against other players rather than against the house, where the operator takes rake instead of holding an edge, and results depend on the skill of the field rather than a fixed return-to-player figure. Where a brand offers a sportsbook, the withdrawal policy is generally shared across products — so the payout checks on this page apply equally to a sports balance.

Paying in and getting paid

There is no charge to use Online Casinos. Costs start at the casino, and they are worth understanding before you sign up.

Specific timings, minimums and limits vary by operator and appear on each casino's banking page — always the authoritative source. Two universal points: verification (ID and proof of address) must be completed before a first withdrawal clears, so upload documents at signup rather than waiting; and withdrawing while a bonus is still in play will usually forfeit the bonus and anything won from it.

Licensing, eligibility and your protections

You must be 18 or over to gamble in Great Britain. Operators licensed by the UK Gambling Commission must verify your age and identity, offer deposit limits and time-outs, and connect to GAMSTOP, the national self-exclusion scheme. Not every site advertised to UK residents holds that licence — some operate under other jurisdictions, which changes what recourse you have if a dispute arises. We cover that distinction separately on our guide to casino sites outside GAMSTOP, including the trade-offs involved.

Whatever you play, check the operator's stated licence yourself on its footer, know that gambling winnings are not taxed for players in the UK, and use the deposit limits and reality checks built into your account. Our responsible gambling resources set out the tools available and where to find free, confidential support. The site's terms of use cover how this comparison service itself operates.

Why online play suits many UK players

Compared with a trip to a land-based venue, playing online gives you published return-to-player figures on every game, far lower minimum stakes, and account-level controls — deposit caps, loss limits, session timers, self-exclusion — that simply do not exist at a physical table. Welcome offers and ongoing promotions have no real high-street equivalent, the game range is far wider than any floor can hold, and you can close the tab whenever you like. Used with limits set in advance, it is the more transparent and more controllable way to play.

Getting started, and getting in touch

If you are opening your first account: choose a brand from the table, register with accurate details that match your ID, upload verification documents immediately, set a deposit limit before you fund the account, then decide whether the welcome offer suits how you intend to play. Opting out of a bonus is always allowed and leaves your balance free to withdraw.
