Existing Customer Offers

21.co.uk Casino doesn’t have a set promotional calendar of promotions and offers. They do host various offers based on certain slot games and events.

It’s worth noting here that when there is a 21.co.uk Casino free spins giveaway, those free spins don’t come with any wagering requirements. Anything you win from any free spins is yours to keep without having the hassle of jumping through any virtual hoops.

To keep up to date with all the latest giveaways, head to your account section and make sure you select that you want 21.co.uk Casino to contact you. You can also find all the new offers in the casino, live casino and sportsbook by clicking on the Promotions tab at the top of the homepage.

Finally, there isn’t a 21.co.uk Casino loyalty or reward programme up and running at the time of asking. Personalised offers are sent via email and via the messaging system when you log in.

Site + Mobile


The design of the 21.co.uk Casino site is minimal and slick. Black, sky blue and white dominate the colour scheme. Don’t expect much in the way of fancy flourishes or visual flair here. Visually, it’s all very simple but none the worse for that.

Everything is clean and crisp and easy to see against the black backdrop. It’s a bit no-frills but navigation is very straightforward. It certainly doesn’t have the visual bells and whistles you’ll find at sister site LeoVegas Casino.

The design at 21.co.uk is more reminiscent of a live, brick and mortar casino. That’s no surprise when they are best known for their TV viewership and their live casino offering.

Like most of the top online casinos, there’s a carousel at the top of the 21.co.uk homepage where you’ll find the latest offers and giveaways, new releases and other newsworthy items. Below the carousel are blocks of games and offers from all parts of the casino and sportsbook. Our main interest is of course online slots so click on the Slots tab for the designated slots area.

There you’ll find slots listed in rows of 4. There’s not much in the way of filtering here. It doesn’t advertise it, but the search box can be very helpful here.  The search box doesn’t just bring up a  specific title if you type it.

Type in the name of a slot provider and it will bring up all the games from the said developer too. If, for example, you only want to browse games from NetEnt or Blueprint Gaming, just type that into the box and you’ll be shown a filtered list of all the available slots from that provider.

We’d like to have seen more detailed filtering by theme, feature and volatility but it is certainly better than nothing. Some casinos don’t have a search function at all, so it’s nice to see a search bar available here.

21.co.uk Mobile App

If you’re one of the growing number of slots players who like to spin on your smartphone, 21.co.uk is very mobile friendly. There are specially designed 21.co.uk Casino mobile apps for both Android and iOS users which are available to download from the Google Play Store and the App Store respectively.

The app is very easy to use. You’ll find the crisp design of the desktop site as well as a bumper catalogue of slots. New players are eligible for the welcome offer. To get started, here’s what you need to do:

21.co.uk Casino iOS App 21.co.uk Casino Android App
Head to the App Store Go to the Play Store
Search for ‘21.co.uk Online Casino’ Search for ‘21.co.uk Online Casino’
Tap the app icon and ‘Install’ Click the app icon and then ‘Install’
Enter your login details Log in and start playing

All casino games and slots that are found in your browser will be available on the 21.co.uk app. They tend to offer more promotions on mobile too.



Despite their emphasis seemingly being on table games, there’s still plenty on offer for 21.co.uk slots players. You’ll find games from a good variety of software providers from industry giants like NetEnt and Microgaming through more niche operators like 4ThePlayer and Iron Dog Studio.  Here’s the full list of slot developers:

NetEnt Play ‘n GO Big Time Gaming
Blueprint Gaming Novomatic IGT
Red Tiger Gaming WMS Thunderkick
Microgaming Push Gaming Lightning Box Games
NextGen Gaming ELK Studios Eyecon
Bally Yggdrasil Gaming iSoftBet
4ThePlayer Pragmatic Play Iron Dog Studio
1×2 Gaming Nolimit City ReelPlay

The main omission here is Playtech. If you’re after the Age of the Gods Jackpots series or Playtech’s branded slots, you won’t find them here. There are plenty of alternatives on offer, including jackpot slots. We’ll look at these in detail shortly. First, we’ll take a deep dive into the slots catalogue at 21.co.uk Casino.

The catalogue of slots available at 21.co.uk Casino is pretty good. The roster of games to choose from currently stands at just over 650 and is rising all the time with new releases.

With a large selection of developers represented, you’ll find pretty much every theme, style and feature you could wish for from an online slot. When you head to the Slots page, the games appear to be listed by popularity.

At the top of the page, you’ll see loads of familiar favourites including NetEnt’s sci-fi classic Starburst, Play ‘n GO’s ancient Egyptian treasure hunt Book of Dead and popular live casino slot turned online classic Rainbow Riches.

It’s not just old favourites that adorn the virtual shelves at 21.co.uk Casino wither. You’ll find plenty of new releases here too. Expect all the latest releases from top slot providers listed above.

There isn’t a specific tab that displays all the new releases though which is slightly unusual. Your best bet is to click on the Feature tab which offers a selection of recommended, popular and newly released.

Jackpot Slots

There are over 50 jackpot slots to choose from at 21.co.uk at the moment.  The range includes slots from the Jackpot King network from Blueprint Gaming including Cop The Lot, Fishin’ Frenzy and The Goonies among others.

You’ll also find a decent selection of Hourly Drop jackpot slots by Red Tiger Gaming which must hit within a specified time period. These include Totem Lightning, Mystery Reels, Dragon’s Luck and Arcade Bomb. You can also play slots from the Diamond Spins series including Volcano Queen, Mystery of Egypt and Cleopatra.

It doesn’t have the Microgaming giants like Mega Moolah or some of the Playtech Age of the Gods slots but there’s still a solid offering of jackpot slots available at 21.co.uk Casino. If you want the biggest possible jackpots online, check out our dedicated progressive jackpot slots section.

Megaways Slots

If you enjoy slots that use the Megaways game mechanic, you’ll have a good pick of games to choose from here. There isn’t a specific section on the site but if you type Megaways into the search box, you’ll be presented with the current Megaways catalogue.

There are over 55 Megaways games available at the time of writing this 21.co.uk review including the grand-daddy of them all, Bonanza Megaways from Big Time Gaming. Other favourites include Odin Infinity Reels Megaways (ReelPlay) Piggy Riches Megaways (NetEnt) and Rainbow Riches Megaways (Barcrest).

Slots Summary

There’s plenty to choose from at 21.co.uk Casino. The filtering is very basic though. If you know exactly what you’re looking for, it’s fine. You’ll find it in an instant. If you want to browse by themes, style, feature or volatility, for example, you’re out of luck. Expect to do plenty of scrolling here.

The catalogue itself is quite impressive, offering a decent variety of games from a massive number of providers. Whether it’s retro classics, brick and mortar conversions or slots with cutting edge technology, you’ll find them at 21.co.uk.

Payment Methods

Deposits and withdrawals at 21.co.uk Casino are limited to debit cards and PayPal. You won’t be able to use money wallets like Skrill or Neteller to fund your account. The good news here is that all deposits and withdrawals are free from any fees. Make a deposit and it should hit your account immediately.

All withdrawals will be pending for 24 hours. Once they’ve been approved by the verification team, PayPal withdrawals are usually processed in a matter of hours. Things take a little longer with the debit cards, usually 2 to 3 days.

To make a withdrawal, head to your profile, click on the Withdraw link and follow the instructions. The minimum deposit and withdrawal amount is £10.

Security and Account Verification

21.co.uk Casino is part of LeoVegas Gaming PLC and is regulated by the UK Gambling Commission. The license number is 39198.

In most cases, 21.co.uk will verify your account automatically. If for some reason they can’t, you’ll have to confirm your identity by providing a combination of photo ID and recent bank statements or utility bills. It’s a quick and straightforward process that’s usually completed in under 24 hours.

There’s a designated link for uploading documents. They also have a dedicated email address if you want to use that instead – [email protected].

Customer Support

If you run into difficulties, try the Help section first. It’s searchable and covers most basic queries. If you need to get in touch, the 21.co.uk Casino customer support team is available around the clock via live chat.

There’s an ever-present blue Help tab in the bottom right-hand corner of the screen. Click on this to activate the live chat. 21.co.uk support doesn’t have a telephone number but I’ve requested a call back before and they’ve called me right away.

The team, like the one at LeoVegas, is professional, efficient and friendly.

Review Summary

We found 21.co.uk Casino to be a bit of a mixed bag. On the positive side, there’s a top selection of slots to choose from here from a wide range of software providers. If you’re playing on the go, the 21.co.uk Casino mobile app is excellent. It’s a PayPal casino too which means quick and convenient for deposits and withdrawals. Verification is usually automatic.

The main focus at 21.co.uk appears to be table games which is understandable given their TV presence. Navigating the slots part of the site isn’t the most intuitive and it’s not always easy finding what you’re after. The content is there, you might have to dig a bit to discover it.

A welcome bonus is always good to see but we’ve seen better and the range of promotions isn’t the most extensive for existing players.

Think of 21.co.uk as a stripped-down version of LeoVegas Casino. It has a good selection of slots but lacks the bells and whistles found in its big brother.
