The Casumo UK casino has been around since 2015, and has developed since that time to become one of the most popular online casinos available to players in the United Kingdom. That popularity increased in 2020 when Casumo branched out into sports betting too. The site is now split into three – the traditional casino, the live casino and the sports betting side of things. For the point of our Casumo Casino review we are going to concentrate on the casino side of things, and to try and explain why Casumo has built up such an amazing reputation for themselves. For all you need to know about the Casumo UK casino, keep reading our exclusive review.

What is the Casumo UK Casino?

Casumo Casino Logo The people behind Casumo came together with the intention of creating a vibrant and colourful casino site in 2015. Casumo was one of the first casinos that took a sideways approach to how online casinos should look. At the time all online casinos kind of looked the same – online renditions of real world casinos.

Upon launch Casumo introduced us to the character Casumo – a white blob with arms and legs who went around wear a red mawashi, which is the only item of clothing sumo wrestlers wear while wrestling. The name ‘Casumo’ comes from a portmanteau of ‘casino’ and ‘sumo’. This character though has now been dropped by Casumo although the style of the site is just about the same.

Casumo of course has proper licensing in the UK, from the United Kingdom Gambling Commission. The company behind the Casumo UK Casino is registered in Malta, and has a global gambling licence from the Malta Gaming Authority.

Casumo Review: A Summary Of Our Experience

After we had had a little lie-down after working through the rather long-winded registration process, we were very pleased by what we found behind the doors of the Casumo UK online casino.

The site has a very bright and minimalist design, and we like the fact they you are not constantly bombarded by the latest promotions available here, as you are at other sites. Don’t get us wrong – we love promos, but we don’t like them shoved in our faces whenever we log on for a bit of slotting play.

The bombardment of slots gets less of a thumbs up, but by using the filters were we able to filter out the providers that makes games which don’t appeal to us. By searching we also were soon spinning our favourite titles.

We really like the ‘instant banking’ cashier option. European-based casinos usually have this option but UK-facing ones generally do not. It’s great to see Casumo offering us the same convenience of our EU-based friends!

Is Using the Casumo Casino UK Safe?

Because Casumo has a UKGC licence, you can bet your bottom five pound note that this site takes your browsing safety very seriously indeed. It is a provision of the award of a UKGC licence that a site puts into place strict protocols to protect your data and encrypt any traffic that comes from or goes to the site.

When you (and if you) take a look at the rather long-winded sign up process at Casumo you can see there is a huge amount of information that you share with this site. This includes your name, address, date of birth and your phone number. If you make a deposit at the site then you will be sharing financial information too. That’s a lot of sensitive info, but the chances of being compromised are negligent. Casumo uses the same kind of data encryption techniques as online banks.

If you look at other, independent reviews you may find claims that Casumo is a scam site. We can tell you that such claims of any kind of ‘Casumo scam’ are very much barking up the wrong tree. This site ticks all the boxes when it comes to fairness and transparency, and independent Casumo Trustpilot reviews agree with us.

Casumo UK Casino Sign Up Offer

As Casumo is an online casino, it of course comes with an online casino welcome bonus for new customers. This is not the type of hefty bonus you see within the online casino bonus realm though. It’s a 100 percent bonus offer up to a maximum of £25, plus 20 bonus spins on top. That’s not the most thrilling bonus we’ve ever encountered, but it’s still one that’s worth investigating.

You have to be a new customer and opt-in to receive your bonus. Your first deposit must be for at least £10 and no matter how much you deposit, the maximum amount that Casumo will match with bonus cash is £25. You also receive 20 bonus spins on the Play’n GO slot Rich Wilde & the Book of Dead.

Also bonus cash and Casumo casino free spins winnings need to be wagered 30 times over before you can cash them out. You cannot spend more than £5 on a single spin or £10 per round at the live casino while doing so. You have thirty days from the award of your bonus cash to complete your wagering.

Casumo offer Offer description Wagering requirement Offer expiry Min deposit
Deposit Bonus 100% Bonus up to £25 30x 30 Days £10*
Bonus Spins 20 Bonus Spins on ‘Book of Dead’ 30x 30 Days £10*

* you only have to make a single £10 deposit to receive both offers, not two.

Ongoing Promotions at the Casumo Casino

The Casumo UK casino is a little bit lighter on the ongoing promotions front than other casinos that we have encountered, but that should not put you off from singing up with them. The ongoing promotions that they do have are genuinely decent, and as they change on quite a regular basis, there’s always the chance of some manner of fresh promo coming your way that’s really going to appeal to you.

As an example, here is a list of the ongoing promotions at the Casumo UK casino that were applicable at the time of our Casumo Casino review, including any relevant Casumo promo code. Make sure though that you check the site so you get the latest information about ongoing promotions at the Casumo casino:

Games Offered at the Casumo UK Casino

There is one thing that’s true about all online casinos – they live or die by the quality of their games. No matter how stylish, functional and easy-to-use an online casino may be, if the games are trash then you are not going to be paying many return visits.

Fortunately at the Casumo UK Casino the games are anything but trash, with a decent number of quality titles from many of the best online gambling software providers. Here is a quick run down of the all the games you’ll find via your Casumo Casino login.


If there is one thing that online casinos are all guilty of, it’s that they bloat their casinos with slots. There are enough slots at the Casumo UK Casino, that’s for sure: 2,100+ of them! Finding your way around such a menu could be a nightmare, but Casumo does offer sorting and filtering options. You can even filter via the impressive array of providers, which includes NetEnt, Microgaming, IGT, Quickspin, Playtech and Pragmatic Play.

If you’re interested in a Casumo payout review, all slots come with published RTPs.

Table Games

Table games are not as numerous as slots, but there are 50 of them from a dozen providers. You can enjoy roulette, blackjack, three card poker, pai gow poker, casino poker, let it ride, craps, and dragon tiger.

Video Poker

There are several video poker titles but because they are lumped in with the other games, they can be hard to find. Hint: Use the search function.

Live Casino

There are live casino options at the Casumo Casino thanks to Evolution and Pragmatic Play with 42 tables. There are lobbies for roulette, blackjack, baccarat, sic bo and the game show-style ‘Mega Wheel’.

Instant Win

We could find no instant win or arcade-style games here.

Casumo UK Casino Payment Methods

Getting cash into your Casumo UK account is a breeze, and there are multiple methods available. One instant sour note though – the Casumo Casino does not accept PayPal.

Unlike other online casinos, the default payment system recommended at the Casumo UK Casino is instant banking. There are a total of 19 banks that use this system, including Barclays, First Direct, Halifax, Lloyds, NatWest and TSB. This is incredibly convenient and recommended by us.

All the other usual suspects are available here, and here’s our list of the ones available.

Banking Method Fees Min Deposit Min Withdraw Withdraw times
Debit Card Free £10 £1 1-3 days
Instant Banking Free £10 £1 Instant
Skrill Free £10 £1 Instant
Pay By Mobile Free £10 N/A
MuchBetter Free £10 £1 Instant
Neteller Free £10 £1 Instant
Paysafecard Free £10 N/A

Casumo Casino Software Providers

If you were paying attention then we’ve already told you that the Casumo UK casino offers over 2,100 slots, plus over 100 games on top of that. A lot of games means a lot of providers, and there are around 70 providers contributing software to this site.

Casumo has picked nearly all of the best names in the business when it comes to the provision of their games. Very few online casinos have games from NetEnt, Microgaming and Playtech all rubbing each other’s shoulders, plus there’s other ‘top of the range’ providers too such as Play’n GO, Pragmatic Play and Quickspin.

Top providers means top games of course, and via the site filtering system you can easily discover the games that most Casumo UK players love the most. There are no surprises! Included in that list are Gonzo’s Quest Megaways from Red Tiger (originally from NetEnt of course), Starburst from NetEnt and our personal all-time fave, Immortal Romance from Microgaming.

Table Games

If slots leave you cold then you can warm yourself right back up at Casumo by taking a look at the table games available. There are countless casino classics with multiplie variations. This means that if you get bored with one version of, say, roulette, you can quickly switch to a different one.

Live Casino

The live casino has lots of lovely lobbies and lots of lovely dealers (of all genders) in order to enhance your live casino experience. The live casino software here is provided by industry experts Evolution and Pragmatic Play.

Software providers available via your Casumo Casino:

2By2 Gaming, all41studios, Bally, Barcrest, BetDigital, Big Time Gaming, Blueprint Gaming, Crazy Tooth Studio, DiceLab, ELK Studios, Fantasma, Fortune Factory Studios, Foxium, FUGA Gaming Technologies, Gameburger Studios, Golden Rock Studios, Hacksaw, IGT, Inspired, Just For The WIn, Kalamba Games, Lightning Box, Max Win Gaming, Merkur, Microgaming, Neon Valley Studios, NetEnt, NextGen Gaming, Northern Lights Gaming, Novomatic, Nolimit City, NYX Interactive, PG Soft, Play’n GO, Playson, Playtech, Pragmatic Play, Push Gaming, Quickspin, Rabcat, Red Seven, Red Tiger, ReelPlay, Relax Gaming, SG Digital, ShuffleMaster, Snowborn, Stakelogic, STHLM Gaming, Stormcradt Studios, Thunderkick, Triple Edge Studios, WMS, Yggdrasil.

The Casumo Casino App

Casumo is something of a 2020s rarity when it comes to a Casumo casino app, as you can use the site via a browser or download a dedicated Casumo app. Both work equally well.

For the Android Casumo app just head to the site via your browser and if you haven’t got the app downloaded, you will get a prompt to download from Google Play. Alternatively, you can just search Google Play yourself for the Casumo casino mobile app.

The same goes for owners of Apple-based devices. The Casumo casino app can downloaded and installed from the Apple App Store, straight to your device.

The Casumo casino mobile app has all the functions of the main site, including access to your cashier account so you can move your money. We have to say though that we’ve seen better apps, as this one feels a little ‘clunky’.

Casumo Online Casino – Support

Casumo does not leave you high and dry if you get into a little bit of trouble, which of course is to be expected. People leaving Casumo Trustpilot reviews have highlighted the site’s helpful support options. There are many ways in which you can get help at this site, including the following:

  • FAQs: Casumo have done a lot of thinking about their FAQs, so if you have a common query that you really need an answer to, you’ll likely to find satisfaction here.
  • Live chat support: Like chat is available, and all hours of the day and night. When we tried it a ‘bot’ answered us, but a real person took over within ten seconds.
  • Telephone: A phone number for Casumo UK support is not available.
  • Email: Available via [email protected]

The Casumo UK Casino – What’s Hot or Not?

Almost everything gets the thumbs up from us at the Casumo UK Casino – and we’re going to say almost everything as nothing is ever perfect! Having said that, there are hardly any negatives here at all – and the positives far outweigh the minimum number of negatives we’ve uncovered.

Here’s a quick run-down of the best aspect of this casino site, and a couple of improvements we would like to see.

What we like:

  • Well over 2,000 online slots
  • Casumo payout review shows excellent RTPs
  • Instant Banking payment option is a real plus
  • Twin live casinos from top providers
  • Minimum withdrawal is just £1!

What we don’t:

  • PayPal payments not available
  • Casumo Casino app could be better

Casumo UK Review Bottom Line

Our main ‘moan’ about the Casumo online casino is that the cute little ‘casumo’ is around no more – we asked support and they said he had retired. We think it’s more likely the UKGC thought him too cartoon-y, and told him to make himself scarce.

What the Casumo UK mascot has left behind is still excellent though. There are perhaps too many slots (it’s going to hard for anyone to get through all 2,000) but at least table games have not been neglected, which is something that commonly happens at lesser sites.

With plenty of payment options too (the ease of the Instant Banking option is a definite bonus) and countless decent bonuses, a trip to the Casumo Casino should be a very rewarding one for anybody.

Casumo UK Review – Casino FAQs

Do I have to be in the UK to open a Casumo Casino account?

Casumo will allow registrations from many countries all over the globe, but if you are in the UK, you are covered by the UK site licensed by the UKGC.

Will the online version of Casumo work in any browser?

It should do, but for maximum compatability Casumo recommends you use the Google Chrome browser.

What happens if a game freezes when I win?

The 'win or lose' info is sent from Casumo Casino's server which then triggers the game. This means that should a game freeze, Casumo will have the record of your win, so don't worry!

What's a 'Reel Race' ?

It's a slots tournament on a specific slot or a range of slots. The people who win the most on qualifying slots during an alloted time period get to share in a prize pot bonus.

Do I need a different Casumo casino login to use the Casumo sports book?

No, you only need one login to use the Casumo casino and the Casumo online bookie.

Can I just withdraw my deposit bonus?

No. Your deposit bonus can only be used for wagering at Casumo and can never be withdrawn.
