King Casino UK Review

King Casino’s had its UKGC licence since November 2014, so you know it’s not some fly-by-night operation.

AG Communications Limited (part of Aspire Global) runs the show. The welcome offer’s as straightforward as they come: pop £20 on Big Bass Splash and you’ll get 20 free spins on the same game - whatever you win, it’s yours. No wagering requirements.

You’re spoilt for choice with over 1,500 games covering slots, live casino and Slingo - with big names like Evolution, Play’n GO and Pragmatic Play in the mix.

But there are two things to keep in mind before you jump in: players have flagged up slow withdrawals, and there’s no loyalty programme if you’re in the UK.

If you love loads of choice, you’ll be happy here. But if you want quick, rock-solid cashouts, it’s a bit hit and miss.

How do I sign up at King Casino?

Signing up is dead easy, and it’ll take you about two minutes:

1. Head over to kingcasino.com and hit “Join”.
2. Just pop in your email address and pick a password.
3. Add your name, date of birth, address and phone number - the usual bits.
4. Choose your marketing preferences and you’re done.
5. Make a deposit to activate your account.

Identity checks usually happen when you make your first withdrawal, not at sign-up. You’ll need a photo ID and proof of address - a passport or driving licence for the ID, and a utility bill or recent bank statement for your address.

Uploading these before your first cashout will save you hassle later on.

Is King Casino a legitimate UK casino?

King Casino is run by AG Communications Limited, under a UKGC remote casino licence that’s been active since November 2014.

Licence number: 039483-R-319409-018 | Status: Active - you can check this on the UKGC register.

The site uses 128-bit SSL encryption - it works, but most UK sites use the stronger 256-bit standard these days.

Games are independently checked by iTech Labs and eCOGRA. GAMSTOP integration is in place, so UK players can self-exclude across all participating casinos.

AG Communications has two past UKGC enforcement actions - you’ll find the details in the Regulatory Notes appendix. The licence remains active and in good standing, with no suspensions or revocations.

What can you actually play at King Casino?

There are over 1,500 games from 30+ providers, including all the big hitters like Evolution, Pragmatic Play, NetEnt, Blueprint, Microgaming and Red Tiger. Basically, if it’s a popular slot, it’s probably here.

The live casino is powered by Evolution, with over 160 tables - Lightning Roulette, MONOPOLY Live, Mega Ball, plus loads of blackjack and baccarat. There’s a proper Slingo section and even a Megaways category (not every site bothers). Favourites like Book of Dead, Big Bass Bonanza, Gates of Olympus, and Eye of Horus are all here too.

You’ll find RTP info on each game’s page. There’s no overall average RTP published for the site, and we also couldn’t confirm if the most popular titles run at their standard or reduced RTP.

If transparency on RTP matters to you, be aware the casino isn’t putting this data front and centre.

Deposit methods

King Casino offers a good range of payment options, and deposits land instantly with all of them.

Additional methods are available depending on your location and may include Neteller, Open Banking, Zimpler, Payz, and others - the full list appears on the deposit page once you're logged in. The minimum deposit to qualify for the welcome offer is £20.

Withdrawal methods

You’ll get your withdrawals sent back to the same method you used to deposit. Usually, you need at least a tenner to cash out, but if you’ve got less, they say you can ask and they might sort it for you.

That’s what’s advertised. But in reality, Trustpilot tells a different story. With a 1.9 out of 5 from 396 reviews, most of the feedback centres on withdrawal delays, and several independent players mention waiting weeks or even months.

King Casino has replied to just 35% of negative reviews, so most go unanswered. That gap between the promised 0 to 2 day e-wallet withdrawals and what real players are seeing is worth bearing in mind before you deposit.

Is the King Casino app worth downloading?

King Casino’s iOS app is available on the Apple App Store, scoring 2.6 out of 5 from 16 ratings. That’s a low score, even from a small sample, and reviewers mention server issues and games not loading properly.

The Android app seems to have vanished from Google Play. The link on King Casino’s own website doesn’t go anywhere, so Android users are stuck with the mobile browser for now.

We tried it and found navigation straightforward, with games loading fine on recent phones and the whole library being there. Still, for a site with over 1,500 games, seemingly not having a working Android app is a real drawback.

How do you get help at King Casino?

If you need help, there’s live chat (once you’re logged in), email (support@kingcasino.com), and a contact form. No phone line though, so don’t bother looking for one.

Live chat is open from 6am to 11pm GMT, 7 days a week, not round the clock.

Before you sign up (or if you're not logged in), support is trickier to find than it ought to be: only the contact form is easy to spot if you’re not logged in.

On Trustpilot, King Casino only responds to about a third of bad reviews, which isn't great, and it means many complaints are just left hanging.

Does King Casino take responsible gambling seriously?

King Casino offers responsible gambling tools in your account area, including deposit limits (daily, weekly, monthly), time-outs, reality checks, and self-exclusion - even up to closing your account for good.

GAMSTOP integration is confirmed. The site links to GamCare (0808 8020 133) and BeGambleAware for external support. Tools are accessible from the account menu once logged in.

The March 2025 UKGC enforcement action against AG Communications included documented self-exclusion failures between 2023 and 2024. The operator has since completed a third-party compliance audit and enhanced internal training.
