Casino Kings Casino Review (2026) - Large Slots Library

Operating in the UK market since 2014, Casino Kings is a hybrid online casino and sportsbook focused on simple, straightforward gaming.

The platform offers a library of more than 4000+ casino games, supported by an integrated sportsbook and a range of regular promotions.

In this review, I’ll take a closer look at the key features, including its game selection, bonuses and overall user experience.

Casino Kings is operated by ProgressPlay Limited, a Malta-registered company who run a number of UK casino sites.

This platform is licensed and regulated by the UK Gambling Commission (UKGC) - licence no. 39335.

One of the UK's most prolific casino operators, they run a number of sister sites, including Winissimo, Fruity King, Betrino and Vegas Wins.

Casino Kings runs ongoing promotions beyond the welcome offer, with the standout being the Wednesday Wheel of Spins promotion.

Players can opt in on Wednesdays with a minimum £20 deposit to spin the wheel and randomly receive between five and 500 free spins on selected games.

Casino Kings operates a loyalty rewards program where players accumulate points as they play, which can be redeemed for tailored promotions, exclusive bonuses and special rewards.

Casino Kings does not currently offer a VIP program.

Casino Kings supports a solid range of payment methods, including Visa, Mastercard, PayPal, Skrill, Neteller, Payz, MuchBetter, Paysafecard, Neosurf, Apple Pay, Pay by Mobile, Bank Transfer is also available for those who prefer direct banking.

Skrill and Neteller deposits are excluded from the welcome bonus.

The minimum deposit is £20 and deposits process instantly in most cases.

The minimum withdrawal is £5 and when it comes to withdrawal times, e-wallet payments are the quickest option, typically processed within a few hours. In contrast, debit card and bank transfer withdrawals can take between three and seven working days to complete.

A withdrawal processing fee of 1% (up to £3) applies per withdrawal.

Documents required for the KYC process include a valid photo ID (passport, driving licence or national ID) and proof of address (utility bill or bank statement dated within three months).

I would advise completing KYC proactively at registration rather than waiting until you try to withdraw, as doing so early avoids unnecessary delays. 

Based on my experience, standard document verification was completed within 48 hours of submission, which is in line with what you'd expect from a well-regulated UK operator.

Age verification checks are carried out as a matter of regulatory compliance.

Casino Kings offers a games library of 4000+ casino games.

Vast Slots Library

The staggering slots section features games from Pragmatic Play, Play'n GO and Blueprint Gaming.

Highlights include high-variance fan favourites like Big Bass Bonanza and Reactoonz

Eyecon Progressive Jackpots

Casino Kings offers a limited selection of + progressive jackpots from the Eyecon network.

Current titles include Heart Burst Jackpot and Irish Luck Jackpot.

Players looking for a vast progressive slots library and huge jackpot wins are better off going to another casino, as these jackpot slots payout much more modest wins.

Authentic Live Casino Tables

The live casino offering at Casino Kings is average, with 110+ live dealer tables currently available.

Provided by Evolution Gaming, the selection includes the usual live blackjack and roulette options, but it also has titles such as Dragon Dragon and Wonderland Lucky Ball for the more adventurous live casino player.

Casino Kings has an iOS app available for download via the Apple Store.

• App Store: 3.9* (15+ reviews)

While testing the app, I was impressed with the smooth navigation; however, some users have reported occasional login issues.

There is no Android app available at this time.

Casino Kings offers a solid range of customer support options, including 24/7 live chat, email support and a comprehensive FAQs section. However, phone support is not currently available.

As part of my review, I tested the live chat service. After being greeted by ‘Fin the Bot’, I was asked a series of questions to help clarify my issue. Within a few minutes I was connected to a live agent who was both helpful and efficient, resolving my account query without any hassle.

Casino Kings provides a range of safer gambling tools accessible through the account area.

Players can set daily, weekly and monthly limits on deposits, wagers and losses at registration, with any changes to limits subject to a seven-day cooling-off period before they take effect.

A reality check feature is available, which prompts players at set time intervals during a session.

Self-exclusion is available for both definite and indefinite periods. 

Casino Kings is also integrated with GAMSTOP, the national self-exclusion register covering all UK-licensed operators.
