Quick Facts

Monster Casino Review

Phillippa Haines
Last updated: November 17, 2022

Monster Casino is a modern and jovial online casino despite its brand name. Think more Shrek than Godzilla; Monster Casino is a playful gaming site fully equipped with over 1,000 slots and games that you can enjoy in your web browser across all devices. Our full Monster Casino review below will dig deep into all areas of this UK casino's operations until we're satisfied that it's a casino that we can trust and thus wholly recommend to you.

Is Monster Casino Legit?

Everything we've checked whilst conducting this review and testing the casino out for real suggests that Monster Casino is entirely legit and is a safe and reliable casino to join. Let's look at the facts, however. First and foremost, Monster Casino is a heavily regulated casino, possessing a gaming license from the UK Gambling Commission and the Malta Gaming Authority.

For UK players and those in gambling approved jurisdictions, you can play at Monster Online Casino with peace of mind that these regulators have a close eye on all areas of the casinos business. It means that you will access fair, third party tested casinos games that are not rigged. It also means bonuses are reasonable with no unscrupulous terms that make it impossible for you to cash out. Also, if you get into a dispute, which is unlikely, the UKGC and MGA will help you resolve the issue.

Moreover, playing at casinos sites holding these serious licenses means you will have plenty of tools to help you remain in control of responsible gambling. Aside from licensing, Monster Casino operates on the well-known Progress Play casino network, which homes many other famous casinos and betting brands, also called 'sister casino sites', including The Online Casino.

Monster Casino Welcome Bonus

Now that we have the mandatory need to know stuff out of the way let's check the juicy things like Monster Casino's welcome bonus offer for new customers. You need to create a new account and make a real money deposit to claim. We've listed the latest sign up bonus below.

Take care to familiarise yourself with the bonuses terms, which we've also added below for your convenience. We always recommend reading the essential terms associated with any casino bonus you claim so that you don't have any nasty surprises jumping out at you later on down the line. Things like wagering terms, max cash out, restricted, and time validity may seem trivial to start with, but it's essential to know so that you have every chance of cashing out your winnings later on.

As it goes, the Monster Casino welcome bonus is pretty fair and generous. It aligns with what many other leading UK casino sites are currently offering their new customers, so we have no complaints.

Monster Casino Promotions

In our opinion, the difference between a good casino and a great casino is one that looks after all customers and not just the new players it's trying to attract through its virtual doors. This is why it's vital to check what's on offer after the welcome bonus has been dished out. Whilst there are so many new casinos out there to join, we feel that if you enjoy your time in a casino and want to stick around, there have to be good promotions and ongoing rewards for the money you're putting in.

How does Monster Casino do in this area? Pretty well, actually. You'll find all current offers under the promotions section on the site. Generally, there are promotions that all customers can take advantage of every day of the week, such as reload bonuses, free spins, slots tournaments and a rewards program.

The Monster Rewards program is pretty good too. Every time you play selected slots and casino games, you'll collect points you can redeem for more bonuses and free spins. Watch out for days when you can collect points at a faster rate for better value too. On the whole, Monster Casino is serious about catering to all customers, so we're pretty impressed with what's on offer here.

Software Providers: Games Available

As briefly mentioned at the start of this Monster Casino review, this casino operator uses the Progress Play casino platform, one of the biggest. Progress Play Casinos are well known for being reliable and offering a vast choice of games and sports betting options for an all-round online gambling experience.

Games at Monster Casino are provided by many well-known game vendors such as Netent, Pragmatic Play, Yggdrasil and Microgaming. There's a mix of newer and unique game studios such as Fantasma Games and Hacksaw Gaming too. This nicely gives players a superb blend of games and slots.

Software Providers:Microgaming, NetEnt, Evolution Gaming, Nyx Interactive, IGT (WagerWorks), NextGen Gaming, Realistic Games, Blueprint Gaming, Yggdrasil Gaming, Merkur Gaming, Nektan, Betdigital, Eyecon, Big Time Gaming, Elk Studios, Konami Gaming, SG Gaming, Lightning Box, Extreme Live Gaming, Core Gaming, Pragmatic Play, Red Tiger Gaming, Foxium, Instant Win Gaming (IWG), Iron Dog Studios, Gamevy, Felt Gaming
Accessibility: Desktop, Mobile, iOS, Android
Highlights: Megaways Slots, Sports Betting, Evolution Live Games (+ High Limit Tables)

Online Slots

The bulk of this casino's game catalogue is centred on online slots, but since slots are the bread and butter of most online casinos, this is only a great thing. On the front page, you'll find the most popular slots and newest slots available, and there's a handy search tool at the top to help you search for your favourite titles, though the design makes it easy to browse the games. It would be convenient if the design team separated the slots into different categories as other online casinos do. However, it's not a huge problem to find games. Top UK games available include Rainbow Riches, Agent Jane Blonde Max Volume, True Grit Redemption, Arctic Enchantress, Links of Ra, 9 Masks of Fire, Dr Toonz, Fishin' Frenzy and Gemix 2.

There are plenty of new generation slots available, too, including a plethora of Megaways slots from various providers like Break Da Bank Again Megaways, 4 Diamond Blues Megaways, Reel King Megaways, 1 Million Years BC Megaways and Cops & Robbers Megaways. Also, look out for entertaining modern slots with the Link and Win, Hyper Spins and Lock & Win features.

Progressive Jackpots

Not a huge catalogue here, we're afraid, but there are still some games with large payouts up for the taking. Many are the Megaways games, but some Jackpot King slots offer progressive prize pools. Microgaming's Sisters of Oz Jackpot, Shamans' Dream Jackpot, Irish Luck Jackpot, and Beat The Bobbies at The Tower of London Jackpot slots are also available.

Table Games

You'll find Monster Casinos' table games under the corresponding 'Casino Games' tab at the top of the page. For the record, this type of table game is the RNG table game sort (not live dealer games that we will cover in a moment) which are the classic games you play against the computer (or rather, the software Random Number Generator). There's a good choice of the classics, including 20p Roulette,  Atlantic City Blackjack, French Roulette, World Cup Roulette, Downtown Vegas Blackjack, Aces & Eights Video Poker, Blackjack Pro Monte Carlo Single Deck and Spanish Blackjack Gold Series.

Live Games

The popularity of live casino games has exploded in recent years thanks to the almost life-like experience they provide. Many new live game providers have sprung up, leaving us with a good choice of premium live games and not relying on just one provider like it was for a good while. Many online casinos know that catering with a good selection of live games is essential, and Monster Casino provides an excellent live experience. However, the choice is not as extensive as the best live dealer casinos we've reviewed of late, but it will absolutely do! All live games are located in their own area; to load them up, click on the 'Live Casino' tab and choose your game. provides the live dealer games at Monster Casino. There's a decent mix of games such as Immersive Roulette, Dreamcatcher, Baccarat Live, Speed Baccarat, Dragon Tiger, Lightning Roulette, Three Card Poker and Blackjack Party. The casino caters exceptionally well for VIP casino players, with a sizable selection of VIP 'high roller' games with more significant betting limits. If this sounds like the sort of games you're after, you will be able to play titles such as Diamond VIP Blackjack,  French Roulette Gold, Blackjack Grand VIP, Blackjack Fortune VIP and Auto Roulette VIP.

Online Scratchcards

Online scratchcard games aren't for everyone, but those who love to play instant games will find a good choice under the 'Scratchcards' tab. Top games like Boss The Lotto offer instant wins with decent to high RTP payout percentages.

Monster Casino - Sports Betting

Interestingly, there's a great choice of sports betting options available at this casino, which puts this gaming site on our list of recommended casino betting sites. It is not a fully focused sports betting site, but we anticipate that the sports betting options and markets cater to those who love to dabble in online sports betting whilst enjoying casino games and slots. If you are looking for a fully-fledged sports betting site, this may not suffice as it lacks many options that hardened sports betting fans may enjoy. We recommend checking some new sports betting sites that cater for the whole sports betting package if this sounds like you.

The main sports markets available at Monster Casino are Football, Ice Hockey, Rugby, Basket Ball, Cricket and League of Nations. There's also a nifty sports betting welcome offer displayed below if you want to claim a new sports betting offer.

Monster Casino On Mobile

Perhaps a redundant section because all casinos and gambling sites often come "mobile-first" these days; if you are looking to play at Monster Casino on your mobile, you will be able to do so nicely and effortlessly. Monster mobile casino is well designed, and it's easy to sign up, log in, deposit and play games and make sports bets within your mobile browser. There's no mobile app available, but one isn't particularly necessary as gameplay is smooth and seamless on all tablets and smartphones.

Banking: Payment Methods Available

A casino lacking payment options is what this casino is not - we're pretty impressed with how many ways to pay there are. Most mainstream methods are available with the addition of lesser-known and modern yet still safe banking methods. We have outlined them all below:


Since Monster Casino is a UKGC licensed operator, you will need to deposit to play real money games and deposit to claim the welcome bonus mentioned above. To deposit, it's simple. Log in to your Monster Casino account, head towards the banking area and select 'Deposit'. Choose from the list of available casino payment options. Various payment methods are available, so we expect all customers to find a suitable and convenient way to deposit, including Debit Cards, Ewallets like PayPal and Neteller, and instant banking apps like Trustly and EcoPayz. 

💡 You'll also be able to deposit Crypto/Bitcoin via ZanaPay if you happen to dabble in that. Many casino players are opting to use Crypto and Bitcoin at online gambling sites these days, making Monster Casino a perfect destination for all things “Crypto”. If you're new to using Bitcoin Casinos, our guide will help you understand the basics and important need to know facts before you get started.

Upon a successful transaction, your funds and any claimed bonus will instantly appear in your account balance. You're then set to play your fave games and slots!


It's basically the same procedure to cash out, though do bear in mind a couple of extra things when withdrawing at Monster Casino. Like with all online casinos, you'll most likely have to withdraw your funds back to the same method you used to deposit. This is due, for the most part, to anti-money laundering reasons. If that's not possible, for example, if you are depositing by Paysafecard (and Paysafecard doesn't support withdrawals), you'll be offered an alternative which is likely to be a bank wire transfer.

Also, before any withdrawals are processed, you will need to verify your account by fulfilling the Monster Casino KYC (Know Your Customer) procedure. You'll need to upload your ID and proof of address so that the casino can be sure it's really you and that you are over the legal gambling age. You've most likely done this at other casinos, and all UKGC licensed casinos must ask you to do it one time. In rarer cases, Monster casino may ask you to provide your source of wealth (SOW), another UKGC licensing obligation. This ensures that the casino isn't allowing deposits from you when you cannot afford them. Whilst this sounds like a hassle, it isn't; you just need to upload two documents. We recommend verifying your account ASAP to avoid any holdups when cashing out.

Monster Casino will process your withdrawal immediately, though the time it takes to get your winnings depends on the payment method you're using. On the whole, we'd say that Monster Casino is quick to pay, though ultimately, the speed is down to the banking provider. For the fastest cashouts, we recommend e-wallets and instant bank transfers. Generally, you should get your winnings within 1-2 days.

Deposit Methods: Maestro, MasterCard, Neteller, Paysafe Card, Visa, Sofort, GiroPay, Trustly, Skrill, Skrill 1-Tap, Boku, Zimpler
Withdrawal Methods:Bank Wire Transfer, Neteller, Paysafe Card, Visa, Trustly, Sepa, Skrill

Customer Support

We never overlook a casino's customer support because it's vital that customers get help when they need it. You can contact Monster Casino via Live Chat, Phone and Email support. Phone and Live Chat are available 24/7 and provide the fastest help, though if you prefer to put your query in writing, you can shoot the team an email where you'll get a prompt reply. 

Our review team didn't experience any hassle when researching the Monster Casino support experience; we were met almost instantly via live chat - and most importantly, the staff were very courteous and knowledgeable about our queries. If you prefer to find answers yourself, we can recommend the comprehensive FAQ section, which provides a solution to most things.

Monster Casino Sister Sites

Being a casino that utilises the Progress Play Ltd Casino platform, you'll notice that there are quite a few other casinos out there that are sister sites to Monster Casino. We haven't tested them all (there are many!), but we can recommend Monster Casino sister sites, including The Online Casino and Irish-Themed O'Reels Casino.

Monster Casino Review - Our Verdict

Monster Casino is worth checking out. It's not the biggest or most well-known of online casinos - we'd say it's medium-sized though it does stand out from many other Progress Play casinos because they have made an extra effort with their design.

But what really matters is game choice, banking options, bonuses and customer support. The game choice is good; we'd love to see some more live games added, and perhaps if we're nit-picking, some more slot providers with decent progressive jackpots. However, let's not overlook the addition of sports betting at this casino which is a huge plus, so that may appeal to some.

Bonuses and promotions are plentiful and are in line with what other casinos are offering. They are not low wagering or wager-free, but they're not super high wagering either - the offers are average and middle of the road. Customer support is 24/7, which is excellent, and there are plenty of banking options to suit all. Overall, if you're looking for a new casino site with betting options and a decent assortment of games and promos, the friendly Monster Casino may do the trick. You can find out more directly below.
