Our approach to online casino reviews

WELCOME BONUS

Start as you mean to go on - with a nice cash injection! We look for healthy deposit match bonuses with reasonable wagering requirements.

DEPOSIT WITHDRAW

Check which currencies, payment methods and countries are supported, plus any limits on processing payments.

MOBILE TABLET

It’s no good if you can’t play on the go – we test all online casinos on a range of devices to make sure they play super smoothly.

GRAPHICS

For a casino to rate highly, it has to look great and play even better. Bonus points for quirky unique designs and well designed interfaces.

SOFTWARE

Good software = good games = good casino. We explore the software options and look for new and popular games and slots.

USER EXPERIENCE

Overall, what are we hearing on the grapevine about this casino? Are their customers happy? We keep our ear to the ground to find out.

Try your luck at this casino’s collection of over 300 games, consisting of slots, classic table games, immersive live casino games and casual scratch cards. The games collection isn’t the largest, but the casino’s most popular slots, including Rainbow Riches, Spinata Grande or Wicked Tales: Dark Red are definitely worth a spin. The casino has a welcome bonus of 200 free spins and up to £1,000 in bonus money across your first three deposits to get you started. Played through this bonus?

It has more than 400 games to choose from, including hundreds of slots, table games and live casino games. The casino’s games come from a strong line-up of providers, including the likes of Play’n Go, NetEnt, Microgaming and Evolution Gaming, to name a few.

It doesn’t just look the part, it also has an extensive and diverse collection of more than 1,000 games across just about every category, with something for even the fussiest of players to enjoy.

Mansion Casino

It’s Mansion Casino’s modern design and huge collection of over 360 games that make it so appealing. If you’re looking for Playtech casino games, Mansion Casino is for you, but games from other casino software providers are more thin on the ground at Mansion Casino. What’s impressive about the collection, however, is the large number of progressive jackpots - you’ll find several dozen of them, including Jackpot Giant and Leprechaun’s Luck, and there are some pretty big cash prizes on offer. Will you be lucky enough to land a big win? Visit Mansion Casino today and start playing to find out.

Don your virtual reality headset to ‘visit’ a casino set high up in a skyscraper and play a selection of popular games, including Steamtower, Starburst, Foxin’ Wins and Energoonz. But there’s still plenty of fun to be had for traditional casino fans, with an impressive 1,400 strong games collection , featuring titles by a diverse line-up of over 60 providers, from big names to newer ones fast making a mark on the industry. Sign up today and you’ll get your first deposit doubled. Keep an eye out, though- not all deposit methods are eligible for the reward.

VideoSlots

As the name suggests, it’s all about video slots at VideoSlots. This online casino has just about the biggest collection of games around, with close to 3,000 to choose from, developed by the likes of Microgaming and NetEnt, as well as newer, software houses, such as Iron Dog Studio and Foxium. Of course, it’s mostly video slots, with well over 2,000 titles in the library. Titles range from popular classics to hidden gems and new releases, like Bonanza, Pink Elephants, Reactoonz and many more! While slots take centre stage, there’s also a selection of table games, live casino games, video poker and scratch cards. Rewards aren’t just for new players at VideoSlots - Casino Races and Weekend Boosters can give existing players that extra push.

Fun Casino

If there’s one place you’re guaranteed to have lots of fun gambling online, it’s Fun Casino. Packed with titles from big-name providers like Microgaming, NetEnt and Evolution Gaming, you’ll find nearly 300 top-quality games here, from video slots and progressive jackpots, to table games, live casino games and everything in between. Where Fun Casino falls short, is in its offering of regular promotions for existing players, in spite of the generous welcome bonuses for new players. New players are rewarded with free spins for the casino’s most popular slots, including the colourful Starburst and the innovative Finn and the Swirly Spin.

Our casinos are all UK approved

Before every casino review we write, we check against crucial list of key factors. These must be passed successfully for us to consider a casino fit for purpose and to investigate in more detail.

Safe and secure – We bring you only the most secure and trusted online casinos for you to enjoy, easing any concerns about data privacy or payment information.

Play in your currency – modern online casinos can cater to a wide variety of currencies. We list casinos that all provide their players primarily with GBP and several other options.

Legal, authorised and licenced – we promise to only bring you online casinos that are all fully licensed and from a regulated jurisdiction.

If a casino passes on all three counts, it will be tested in the Casino Genius Lab. Our team of experts will review it thoroughly against a strict set of criteria, ensuring only the highest quality casino experiences get our stamp of approval.


The Genius Review: What we’re looking for

Bonuses – bonuses are commonly used by casinos to attract new customers, but they aren’t all designed equally. Our bonus section not only informs you of the available sign up bonuses and regular offers casinos have, but also lets you know of any catches (such as excessive wagering bonuses) that might make a seemingly attractive offer less appealing.

Games – our games section provides you with all you need to know about the slots and live casino games a site offers. There is a huge collection of casino games online and our guide not only reveals the best ones but also helps you learn their rules and shows you where to practice for free.

Software – there is a wide variety of casino software online and some is definitely better than others. In the software section we show you which of them provide the best casino experiences, which might be lacking in certain areas, and which software is featured by which casinos. Not only does this help you find games you’ll love, but also it is an interesting and informative section on tech, graphics and what goes on behind the scenes of your favourite casino games.

Payments – online casinos don’t all offer the same payment options when it comes to deposits and withdrawals. When choosing a UK casino site, it is well worth taking this into account before signing up. Our payments section explains the importance of reliable banking methods, fast and secures transfers and much more


Online Casino FAQs

Are online UK casinos legal?

UK casinos are legal and are regulated by the Gambling Commission, but it is important to make sure they are licensed. The rapid growth of the Internet gaming sector has meant there are unlicensed sites online that should be avoided. At Casino Genius we thoroughly check all of our listed casinos and you can rest assured of their legality.

Do I have to download software?

Different sites offer different ways to accessing their casino interface. The majority of casinos don’t require a download, but some occasionally do. The downloading of software is intended to give the player a higher quality and smooth experience, without relying on a web browser. The casinos we list are all trusted and will not have viruses or negatively affect your computer.

Are UK casinos safe?

The UK casinos that we review all have the highest level of security to ensure your safety. It is important that a site is licensed, as well as providing secure payment options and encryption technology to protect your data. We check all our casinos thoroughly to ensure you’re completely comfortable when signing up to them.

Do I have to gamble with money?

No, the majority of casinos offer a free play service allowing you to play the game and get used to any unique features it has. If you like it and want to play for real money, then that’s entirely up to you. This feature is a great way to have a little fun without the risk or to just find a slot you enjoy.

Why is everyone always talking about new casinos?

You'd be forgiven for thinking that newer automatically meant better. It's not quite as simple as this - although new online casinos do often have a few crucial benefits. For starters, they'll be designed for the modern casino player - fast mobile gaming, multiple deposit methods, quick withdrawals and innovative features from wager-free spins to gamification to bring the experience alive. The big names in the online casino space aren't sitting back and letting their lunch be eaten though - they're working hard to keep up, and often come with added benefits of size and history, such as a strong reputation and track record. Whether a new casino is what you need will depend on the individual. So head over to our new casinos guide and meet the freshest faces on the casino scene.
