Review Summary

Casumo is one of the highest-scoring slot sites in our lists with a 4.8/5 rating. You could say it is the perfect all-rounder, one that suits every type of gambler whatever their budget or game preference. It’s one of the few truly independent casinos where the platform has been developed exclusively for one site. And a lot of money has gone into creating a genuinely first-class user experience. In particular that is reflected in the website and app which is a real pleasure to use. But in fact, Casumo excels in almost all areas from game lists to cashier and support.

Casumo is also widely regarded as one of the top casinos on the market by players and those in the industry. This is reflected in numerous awards received including Casino Operator of the Year (eGaming Review, 2021), Online Casino Operator (International Gaming Awards, 2019 and 2020) and Innovation in Casino (eGaming Review, 2015 and 2014). Casumo also has high ratings from players at Casinomeister and Ask Gamblers, two of the biggest gambling forums online.

We cover all this in more detail in our review. First, here are the key strengths and weaknesses of this site based on our research and analysis.

Strengths

• Safe and trustworthy – Casumo is a big name that has built a reputation for trustworthiness since it's launch in 2012. They are fully licensed in the UK which means the site is safe, fair and secure with plenty of consumer protections in place.
• Huge slots list – if you are there for the slots you won’t be disappointed. The list is well over 3,000 and features games from every top provider. It’s nicely presented with interesting categories and a powerful filter menu to help find games you like.
• Exclusive Casumo Jackpots feature – you can opt in at 9p per spin to play for 4 exclusive Casumo progressive prizes – Mini, Minor, Major, Mega - on 24 popular slots including Book of Dead.  
• Play slots for free - unlike many other online casinos, Casumo allows you to play slots for free before you spend your money, so you can test the gameplay and payouts first.
• Smart website and app is easy to use – the design of both is superb. Everything is easy to find and clearly presented with fun, modern colors and layout and clear, simple navigation.
• Daily Promos reward you every time you log in – every day you can pick up bonuses or free spins via the Umodays deals.
• Integrated loyalty program rewards every bet – all your bets earn you points which are displayed in a progress bar at the top of the screen. Each time you complete the bar, you level-up and receive a reward. It’s simple to follow and the bonuses are great value.
• Join big money slots tournaments for free– Casumo pioneered the idea of ‘Reel Races’ with live leaderboard tournaments where players compete over a set period, earning points for every win on the reels. They still run these most days with huge prizes available.
• Withdrawals processsed in minutes – once you have completed account verification most withdrawals are very quick, sometimes taking just a few minutes.

Weaknesses

• No phone support – you cannot contact the team on phone, only live chat or email.
• Classic Table Games list is small – if you prefer classic table games to live dealer then Casumo might come up short for you. The list of classics is not strong.
• Account verification can be slow – there have been complaints about slow verification and source of wealth checks in the past though Casumo has improved in this are over time.

Make a first deposit of £20 or more at Casumo to qualify for the welcome package. You must opt-in from the Valuables area of your account. You get a 100% match bonus capped at £100 and 50 free spins on Pragmatic Play’s Big Bass Bonanza.

Sign Up Offer Terms

Casumo have bonus terms relating to this offer. Check them out before you deposit to be sure you are happy with the deal.

You are required to wager 30x the value of the bonus and deposit together before you can make a withdrawal of any winnings generated from your bonus. For example, if you deposit £20 and get a £20 bonus then you will need to wager £1,200 (£20+£20 * 30) before making a withdrawal. Winnings from free spins are also credited as bonus funds and must be wagered 30x before they can be withdrawn.

Casumo do not mention a cap on how much you can withdraw from winnings generated from your free spins or bonus funds.

Daily Promotions At Casumo

Casumo is one of the more generous casinos in the UK. Remember, they are a big brand and they have more tools at their disposal to keep you interested than your average small white label. According to their home page, the size of the Casumo site is such that on a daily basis they hand out over 30,000 rewards like these, and over 350,000 free spins each year.

It's very easy to find out what's on offer each time you visit Casumo. Just check the Promos page and the Valuables area of your account under 'Profile'.

Here are the highlights:

• Umodays - daily promotions in which you can pick up free spins and bonuses to use on different games. It’s impressive to see whichever day you show up there will be a chance to take advantage of an offer of some kind. Keep in mind that you normally have to deposit to claim the bonus.
• Umo Boards - FREE Reel Races have always been a huge part of what Casumo is about. These game tournaments are found at many online casinos but few run them as well as Casumo. The number and size of tournaments has changed over the years – there used to be one every hour at least and a headline race each evening at around 8pm but now there are just one or two per day or per week. They are called ‘Umoboards’. The prize pools are just as good with up to £10,000 up for grabs in most tournaments. The great part about the Umoboards at Casumo is that the leaderboards are totally integrated into the games so you can watch yourself rising up the table in real time as you win (and dropping down when you don’t). It costs nothing to take part and races are always opt-in with the TOP 10 players are GUARANTEED a prize at the end.
• Pragmatic Play Drops and Wins - The full Pragmatic Play slots list is available at Casumo and when you play you can enter yourself into their Drops and Wins leaderboard competition at the same time. It costs nothing and there is £20,000 to be won daily in the form of bet multipliers, extra spins and instant bonuses.
• Games Global Jackpot Splash - if you play Games Global (formerly Microgaming) jackpots including WowPot, MegaMoolah and King Millions games then you have a chance to collect a random cash prize on any spin outside the normal gameplay. The prize pool is £1,500,000 over the year with prize drops of up to £1,000 available.

Loyalty Program - Progress Bars, Level Ups, Achievements and Valuables

Casumo built its reputation over the last decade on its gamified loyalty program and it remains a core feature of the site and a reason to play here. All bets placed in the live casino or on slot games are rewarded with loyalty points. These points go towards filling up a progress bar which triggers a level up when full. At each level the rewards get bigger and better, with free spins, deposit bonuses and cash drops being the principle advantages.

This is a much more exciting and innovative loyalty program than the standard points for bonuses systems you find at most casinos. The execution is very nice as well with your valuables and achievmements clearly laid out on your account page. The only downside I found was that it is not clear how much wagering is required to move between levels, nor are there any guarantees to say what specific bonuses you will receive when you arrive at each level. It is left as a surprise instead. When we asked support we were told that this information is no longer given out. However, in our time on the site we moved quickly between levels and earned many spins along the way.

The game list at Casumo is very strong and immaculately presented. There are over 3,000 slots on offer here as well as table games, live dealer, Slingos, Instant Wins like scratchcards and Keno, and a big sportsbook too. 

You can toggle between casino and sports at the top of the website or app to start searching for the games you like. In the casino section you can browse down the page to find slots, table games or instant wins, or use the powerful search and filter feature to browse by game provider or game type. Like everything at Casumo I found it really easy to use.

Game Types

• Slots - A mix of classics, Megaways, grid games, popular series and high volatility
• Megaways - Lots of games using Big Time Gaming's popular mega-payline game engine
• Jackpots - Popular networks including Dream Drop, Mega Moolah and Jackpot King
• Slingo - Over 30 bingo-slots hybrids including Book of Slingo and Deal or No Deal Slingo
• Live Dealer - Stunning live streams including exclusive Casumo tables from Evolution Gaming
• Table Games - Classic video-game versions of blacjack, roulette and baccarat
• Instant Wins - Scratchcards, plinko, keno and bingo games with small stakes
• Sportsbook - 100s of betting markets including football, racing, tennis and basketball

Catalogue and Game Providers

The list of game providers at Casumo is huge – more than 100 in total – creating a vast catalogue of games with a diverse ranges of styles, formats, payout models and complexity. There are too many to mention here but I’ve picked 10 of the best and listed them in this table showing some of their best games too.

Online Slots

Casumo is genuinely a slots players paradise. The list is well-curated with some interesting categories to help you explore. You can start with hand-picked ‘Games of the Week’ or search ‘New and Exclusives’ for the latest releases. Or find evergreen classics like Starburst and Book of Dead under the ‘Top Slots’ header or look for games that are popular under the ‘Trending Now’ section.

There are also personalised areas like ‘Recommended For You’ and ‘Continue Playing’ so you can jump back to your favourites next time you log in. And for those who want to dig deeper there is a filter button so you can search by your favourite provider or categories like Drops and Wins or Megaways. The latter is a stacked list with over 200 titles including Monopoly Megaways, Temple Tumble Megaways and Bonanza Megaways. There is both quality and quantity here, a joy to explore.

Here are 10 games that stood out as worth a spin on the day of this review. I chose them as they represent the best of what Casumo has to offer in it's slots list - top quality artwork, gameplay and maths models from a diverse list of suppliers each at the top of their game!

Jackpot Slots

Casumo is also a great casino for progressive jackpot fans. More than 250 games from all of the big networks are available here. The best way to find them is to use the filter feature. Scroll down until you see Jackpot Type. All these are available:

• Mega Moolah (Games Global)
• WowPot! (Games Global)
• Dream Drop (Relax Gaming)
• Jackpot King (Blueprint Gaming)
• Mega Fortune (NetEnt)
• Age of the Gods (Playtech)
• Megapays (Big Time Gaming)
• Daily Drop and Must Drop (Red Tiger)
• Casumo Exclusives (available on 24 different classic slots)

That is one of the best progressive lists I’ve seen on any casino. But it doesn’t end there.  

Exclusive Casumo Jackpots are also available on games like Starburst, Book of Dead and Big Bass Bonanza. You’ll find a full list on the games page. These are opt-in jackpots with 10% added onto your stake if you want to take part. There are four in total – Mini, Minor, Major and Mega. The Mega is seeded at £90,000 and it regularly tops £1,000,000.

The choice of jackpots is huge, but which should you go for? Here is my top 5 pick and some key facts about each one.

Of these, my personal favourite would be Dream Drop Diamonds - it's a stylish-looking slot with a luxury theme and whilst the Dream Drop prizes won't reach the heights of the bigger networks like Mega Moolah, that is offset by more frequent payouts which can still hit close to £2,000,000 on occasions.

Slingo

Casumo also has a selection of around 40 Slingo games to try. This is not the full catalogue. Some of the originals like Slingo Riches are NOT available. However, there are some excellent branded games like Slingo Rainbow Riches, Slingo Lobstermania and Slingo Cleopatra. If you want a wider choice of Slingo games then we recommend Play OJO with more than 50 to choose from. Or, visit our Slingo Sites page for more options.

Live Dealer

The Live Dealer area is impressive too and can be accessed via the Live link in the Casino section of Casumo. Tables are provided by Evolution Gaming, Pragmatic Play and Playtech, the 3 biggest providers in the industry.

This gives you a massive selection of Blackjacks, Roulettes, Baccarats, Sic Bo, Texas Hold Em and Gameshows. There are also exclusive Casumo tables provided by Evolution Gaming. Unlike the other tables which are shared with other online casinos, the Casumo exclusive ones are only available to Casumo players and the croupiers wear Casumo branded clothing. This just adds to the feeling that you are playing at a big name site.

Here are 10 top live dealer games you can try at Casumo.

Table Games

Like most online casinos, Casumo have shifted away from traditional RNG (random number generator) table games in favour of the far more popular live experience. However, you can still find a limited selection of blackjacks, roulettes, craps, baccarats and video pokers via the home page or the live section.

There are some good roulettes here, including Relax Gaming’s roulette, and classic blackjack. However, the best stuff really happens in the live dealer lobbies.

Casumo is a top-quality, modern website with a clean and simple design. It is easy to find your way around with the main functions like log in, sign up, casino, live casino and sports all clearly available at the top of the home screen as shown here.

Previously you would have called this brand ‘immersive’, as it was set in the Casumo-verse, a cartoon landscape with a fun ‘sumo’ character fronting the show. Each new level earned him a new belt and more rewards. This aspect of the experience has since been toned down for being too ‘child-friendly’. Nevertheless, with its blend of purple, lilacs and whites, Casumo still retains a unique sharpness and style that sets it apart from competitors. Furthermore, throughout the website, whether you are looking for new games, scanning your account pages and or browsing for bonuses, the user journey is clear and easy to follow.

In particular the account area where you can view your profile, update your spend limits, collect valuables and view your account history, is miles ahead of what you normally find at an online casino, exuding trust at every click.

The cashier at Casumo covers all the most popular payment services including debit cards, eWallets and pre-paid cards like Paysafecard. You can also deposit with ApplePay.

Casumo has been built to cater for lower spending customers as well as high spenders. So, you can deposit just £10 on all options and withdraw from £10 too. For more sites like this check out our list of £10 deposit casinos. There are no fees here, deposits are always processed instantly, and withdrawals are fast, subject to account verification.

These are the deposit and withdrawal options, fees and minimum thresholds.

Payout Speed

Withdrawal times at Casumo are generally excellent. They process transactions 7 days a week and usually in under 24 hours. In my experience they can sometimes send your money in just minutes. However, as with all online casinos there are caveats.

If you are making significant deposits and withdrawals then you may be asked to go through KYC (Know Your Customer) checks on your ID and the source of your betting funds. This can slow things down whilst manual checks are done on the documents you send in. There are reports on Trust Pilot of withdrawals taking 2 to 3 days in these cases.

How fast you receive your money after Casumo have done their bit depends on your payment provider. eWallets like Paypal and Skrill typically make funds available immediately whilst banks say they may take up to 5 days to process money back to your card, thought its usually 1 to 2 days in practice.

Know Your Customer (KYC) Checks

All UK-licensed casinos are required to verify player ID, age and source of funds as part of their responsible gambling practices and to prevent fraud and other criminal activity. This process is called Know Your Customer (KYC) or account verification.

As far as possible the work is done behind the scenes via ‘soft’ checks but if you become a regular at Casumo you will almost certainly be asked to go through more stringent checks that require you to submit scans of personal documents. Typically, this happens when you meet a pre-defined threshold on deposits or withdrawals. This is to ensure both that you are playing with your own money and at a level you can afford to.

Which Documents Will I Be Asked For?

 You may be asked to provide scans or photos of any of the following documents:

• Passport
• Driver License
• Utility Bills
• Bank Statements
• Bank Cards
• Payslips

At Casumo you can upload these documents via the Verification page in your account under ‘Profile’. It can then take a few days for the team to review them. Whilst this may feel like an onerous task, and one that may delay withdrawals or even restrict access to your account temporarily, it is a small price to pay for the knowledge that you are transacting with a safe casino that takes its responsibilities seriously.

Casumo support are available on live chat or email. This is a 24/7 service available via the Contact Us link on the website. There is no phone support service.

Live chat is initially with an AI Bot – this can be a frustrating experience as they don’t always understand your question and usually respond with a link to the FAQs. However, you can request to be put through to an agent and the response times are generally very good and agents well-informed.

I also found the FAQ section on the site to be very useful. They cover everything from your account and the cashier to terms and conditions, technical queries and licensing information.

Casumo is licensed by the UK Gambling Commission which means the operator adheres to high standards on player safety, site security and fair gaming. Here are the features and tools that make Casumo a safe place to play.

Responsible Gambling

Casumo provides players with a full suite of RG tools which can be found under ‘Limits’ in the Profile section of your account. This goes above and beyond the basic tools most casinos offer, giving many different ways to manage your spend.

• Deposit Limits – set daily, weekly and monthly
• Spending Budget – deposits minus withdrawals set monthly
• Loss Limit – best minus wins set daily, weekly and monthly
• Wager Limit – how much you can bet daily, weekly and monthly
• Log In Limit – how many hours per day you can log in for
• Log In Time Block – hours of the day when your account will be blocked
• Take a Break – suspend your account for a period of 1 day up to 6 weeks
• Self-Exclude – make your account unavailable for 6 months up to 5 years

On the same page you can also access a Play Responsibly section with lots of advice on how to gamble safely and what to do if you think you have a problem.

Game Testing

All games on the Casumo site have been provided by licensed game developers. They must be regularly tested by approved testing houses to ensure that they payout at the rate advertised in the game (RTP) and in a truly random pattern. This is covered in the Fairness Statement on the website.

Clear and Transparent Bonus Terms

The Gambling Commission is strict on its guidelines around how bonuses are configured and advertised. Casumo follow the rules closely and you’ll find all their offers are clearly worded, easy to follow and fair. Their wagering requirements are quite high, but not unreasonable, and you can access terms and conditions easily too.

Site Encryption

Casumo uses standard encryption protocols once you are logged into your account to keep your personal and financial data safe.

Disputes

All UK-licensed operators are required to provide a clear path for customers who have a complaint. Ultimately, if you are not satisfied with the response from the support team or management then you can take your dispute to an Alternative Dispute Resolution Provider (ADR) who act impartially to resolve the issue. Casumo are required to nominate an ADR and they have chosen eCorga who are well-known in the industry. The service is free.

Insolvency Protection

The Gambling Commission requires all licensees to protect customer balances in case of the operator becoming insolvent. The Commission defines 3 levels of protection – not protected, medium protection and high protection. Casumo fall into the category of medium protection. That means customer balances are held in a dedicated Client Bank Account separate to the main business and arrangements have been made for distribution of balances back to players in case of insolvency, although this action is NOT guaranteed.

NOTE: Most operators fall into the category of not protected or medium protection.

Whilst insolvency is a very rare occurrence for gambling operators, it can happen, and this protection is another reason to play at a licensed site like Casumo.

Player Reviews

There are several trusted online platforms where players can leave reviews of their experiences at casinos. We look at TrustPilot, CasinoMeister and Ask Gamblers to find out what people are saying about Casumo.

Trust Pilot

• Average Score: 2.4
• Total Reviews: 2,131

The spread of scores is weighted towards the lower end with 67% of reviewers scoring the site with a 1/5 or 2/5 whilst 25% gave it a 5/5. It’s surprising to see that Casumo has a poor average score on Trust Pilot.

Most of the negative reviews concern slow withdrawals and account verification which suggests that this remains an issue for some accounts despite reports of improvements in the service. For balance its worth noting that there are many positive comments regarding the speed of withdrawals and the quality of customer services too.

Whilst I would take the negative remarks about account verification on board don’t let that put you off signing up here. Be patient, and if possible, upload your documents in advance to avoid delays when you request that first withdrawal.

CasinoMeister

• Writer’s Review Score: 8.6/10
• Player’s Review Score: 8.3/10

It’s no surprise to see that both Casinomeister’s forum members and the staff writers give Casumo a high score. Like us, the staff writer review highlights the game selection, support service and the website and app as highlights of the experience at Casumo. But once again there are a few reservations about the speed of account verification and withdrawals that shows that things don’t always run as smoothly as players would like in this area.

Ask Gamblers

• Casino Rank: 8.6/10
• Players Rating: 7.6/10

Ask Gambler’s Casino Rank alogorithm looks at all aspects of the players experience and gives Casumo 8.6/10 which is a very good score. The Player Rating is a little lower at 7.6/10 but still not bad at all. There are some comments again about slow withdrawals and one player saying their verification took a month to complete. However, most comments are very positive with particular reference to the jackpots and the loyalty program.
