King Casino Review (2025) - Rapid Withdrawal Speeds

Launched in 2019, King Casino has grown to become one of the UK’s fastest-rising online casinos amongst players.

This UKGC-licensed site offers an impressive library of over 2,400 games, including a huge slot collection alongside some of the fastest withdrawal speeds I’ve seen.

King Casino also has a sleek mobile-friendly platform for playing on the go, which I’ll highlight alongside much more in this review. 

King Casino (licence no: 39483) is operated by AG Communications Limited, a Malta-based subsidiary of Aspire Global.

The company holds a valid UKGC licence, with King Casino listed as a white-label site alongside sister brands such as Mr Play, HeySpin and Casiplay.

Aspire Global’s overarching reputation for fair play, customer safety and secure banking gives King Casino a solid pedigree.

New players can claim up to £150 in bonus funds and 50 free spins across their first two deposits. 

King Casino Promo Code

No promo code is required for this offer – just opt in when making your deposits. 

How it Works

• Deposit £20 or more on both deposits
• Opt in during each deposit process to unlock each offer
• First deposit: 100% match up to £50 + 20 spins on Book of Dead
• Second deposit: 50% match up to £100 + 30 spins on Starburst
• Winnings from free spins capped at £100
• Bonus cash expires after 21 days
• Free spins (valued at £0.10) expire after 24 hours

Wagering Requirements

Both the bonus funds and any winnings from the free spins in the King Casino welcome bonus are subject to 35x wagering requirements before you can withdraw.

That’s slightly higher than most other casinos, but it’s not completely unachievable. Slots contribute 100% towards the requirements, but table games and live casino contribute just 10%. 

It’s important to know that you can’t bet more than £4 per spin (or 15% of the bonus amount) whilst meeting these terms, otherwise it won’t count. 

Is the King Casino Bonus Worth It?

Compared to rival UK casinos, the King Casino welcome offer sits firmly in the middle. The deposit match amounts are modest but accessible, and the split structure encourages players to come back.

The £150 maximum from those deposit matches might seem low to some, but it makes that 35x playthrough amount feel slightly less daunting. 

Plus, getting 50 free spins across Book of Dead and Starburst, two massively popular slots with some genuine winning potential, is a fantastic way to kick things off. 

Key Benefits 

✔️ Double Deposit Bonus - Two-part bonus spreads your balance across two deposits

✔️ 50 Free Spins - Includes a solid amount of free games on Book of Dead

✔️ Accessible Welcome Offer - Open to low-stakes players with a £20 minimum deposit

Who Is This Bonus Best For?

✔️The King Casino welcome bonus is ideal for casual slot fans, as well as players looking to test a new site without committing a large chunk of money.

I found a steady stream of ongoing promotions at King Casino, including weekly free spin deals, reload bonuses and tournament prize draws. 

These offers rotate regularly, and they do a pretty good job of telling you what’s on offer via regular emails as well as the promotions page. 

Sadly, though, there isn’t a formal VIP or loyalty programme here, which means you won’t accumulate bonuses or tiered benefits whilst you play.

King Casino has quite a wide range of payment methods available, including Visa, MasterCard, Trustly, PayPal, AstroPay, MuchBetter, Paysafecard, Skrill and bank transfer.

The minimum deposit is £10, as is the minimum withdrawal – and any cashout requests must be made via the same payment method you used to deposit. 

Almost all withdrawal requests here are processed within eight hours maximum, which is much faster than I’m used to seeing at most other UK online casinos.

As per the UKGC guidelines, King Casino is required to carry out the usual KYC (Know Your Customer) checks that you might already be familiar with.

That means you’ll need to upload a valid photo ID as well as a recent utility bill or bank statement as proof of address, usually before withdrawing for the first time.

I highly recommend getting these checks completed as soon as you’ve signed up, so that you’re verified and able to cash out as quickly as possible. 

King Casino boasts over 2,400 titles from more than 60 providers, offering a deep and diverse collection.

Thousands of Slots

The bulk of King Casino’s game catalogue is slots, with well over 2,000 titles in total. I found the classics like Starburst, Gonzo’s Quest and Rainbow Riches alongside some brand-new titles from up-and-coming providers – there’s a true mix here.

New releases are added weekly, and there are dozens of exclusive and branded titles, too. In terms of progressives, you’ll find just over 40 – not a bad amount, but not the most impressive. That does include standouts like Divine Fortune, though. 

Quality Live Casino Collection

I found more than 150 live dealer tables here too, all of which are supplied by Pragmatic Play Live or Evolution Gaming – the two big hitters in this space.

You’ve got plenty of choice between multiple versions of blackjack, roulette and baccarat, all with varied limits, as well as game shows like Crazy Time and Mega Wheel.

All of these games offer pristine HD streams and professional dealers, and they’re easily accessible via mobile, too – I had a fantastic time trying out some live roulette here via the King Casino app. 

Table & Card Games

If you prefer virtual table games as opposed to live action, you’ll find around 100 of them in total, ranging from American and European roulette to multihand blackjack and sidebet baccarat. 

There’s also a decent selection of poker, red dog and Sic Bo games, along with video poker – but don’t expect a huge offering on this front. 

King Casino has a dedicated app available for both iOS and Android users. However, these apps don’t offer as many games as their desktop counterpart, which is a shame, and they have mixed reviews across both app stores.

However, it performs exceedingly well across the board – I played a number of slots and live dealer games on both platforms at peak hours, and didn’t encounter a single lag or stutter.

The mobile site works just as well, though. Testing it out on both iOS and Android, it felt smooth and reliable, and you’re able to manage things like payments and account settings with ease.
