MonsterCasino review
MonsterCasino is an established UK iGaming and sports betting platform that has been online since 2014. The operator behind the brand is ProgressPlay Ltd, a company with a strong global presence in the UK online gambling industry. You will find a comprehensive catalogue of games, covering thousands of fruit machines and table games, as well as a neat selection of bonuses.
When you sign up as a new player, there is a five-stage welcome bonus giving you a 75% deposit match up to £1,000 + 100 free spins on the popular Book of Dead and Starburst video slot games. Plus, there are regular promotions with free spins and software provider promotions, as well as a flexible VIP rewards programme rewarding players who are regularly active. In this MonsterCasino review, we cover all of this, plus the platform's operator, UKGC licence, payment options and customer support, pointing out the pros and cons of each along the way.
History Of MonsterCasino
MonsterCasino entered the UK market in 2014 and introduced its sportsbook in 2018. The brand is operated by ProgressPlay Ltd, a company registered in Limassol, Cyprus, which also manages other UKGC-licensed sites, including Dukes, Jazzy Spins, and Mr Slot.

Two financial penalties have been issued against ProgressPlay by the UK Gambling Commission; however, its licence has remained active because the breaches were administrative rather than related to game fairness. Additionally, holding a UKGC licence means the brand is subject to continuous oversight, keeping compliance standards to a high bar, thus making MonsterCasino a credible choice for UK players.
MonsterCasino UKGC Licensing Framework, Security and Player Protection
After further researching the UKGC operator licence page, we found that ProgressPlay Ltd holds an 'Active' UKGC licence number 039335-R-319313-020 under account number 39335. Like many other operators in Britain, ProgressPlay Limited is also registered with the Malta Business Registry. This side of the business holds a Malta Gaming Authority (MGA) licence number MGA/B2C/231/2012, which enables it to serve its international clientele outside the United Kingdom.
For UK players, we acknowledge that the UKGC may face criticism for the restrictive rules applied to online slots, including maximum bets and the prohibition on bonus buy features. However, it's a small price to pay when you consider it is one of the most player-protection-focused licensing authorities in the world. For example, all casino websites must adhere to the strict 10 Steps to Cyber Security. Moreover, support teams are obligated to fully address all player complaints, and all terms and conditions are legally binding, with no exceptions.
Another rule that should technically work in your favour is mandatory fund segregation. Unfortunately, ProgressPlay opts to use a 'Not Protected' status. Therefore, should the operator file for bankruptcy, your balance may not be returned. At the very least, it could use 'Medium' protection.
Responsible Gambling in MonsterCasino
Under your user account, a full suite of useful responsible gambling tools is available, which we recommend incorporating into your overall casino strategy to manage your bankroll and playing time effectively.

A broad mix of promotions is available at MonsterCasino, starting with a five-stage welcome offer worth up to £1,000 plus 100 spins. Ongoing deals include weekday mystery boxes, a weekend spins wheel, themed prize drops, and leaderboard events, which makes the line-up more varied than the single reload or cashback offers found at many UK sites.
MonsterCasino Welcome Bonus - 75% up to £1,000 + 100 Free Spins
Most UK casinos stop at a single first-deposit bonus, but Monster Wins offers a welcome package that spans your initial five deposits, giving UK players something different to consider.

MonsterCasino Bonuses for Existing Members – free spins, promotions, real money, and rewards
In our MonsterCasino review, we found that the site doesn’t just lean on its welcome bonus. Existing players can expect a steady stream of promotions, ranging from free spin deals to real-money prize events, along with weekday mystery boxes and weekend wheel spins. You may also notice that reload deposit match deals have been skipped, and instead, the casino focuses on promotions that lead to free spins.
- Mystery Box: This promotion runs Monday to Thursday and requires a £20 deposit with the bonus code MBOX to claim a daily prize of 25 to 100 spins. You will likely land the lower-end 25 or 35 free spins, which, according to MonsterCasino, accounts for nearly three-quarters of outcomes, while the top 100-spin prize is rare. Regarding your winnings, a 50x rollover applies.
- 75 Free Spins: A £10 deposit with the bonus code WARLORDS25 gives you 25 free spins on the Immortal Warlords online fruitie game. You can use the same promo code three times for a total of 75 spins. Just note that all free spins winnings are subject to a 50x wagering requirement.
- Weekend Wheel Of Spins: The Mystery box gives you mid-week action, while the Weekend Wheel of Spins gives you the chance to win free spins over the weekend. From Friday to Sunday, you can earn one spin per day by depositing £20 along with the WKND500 bonus code. Prizes range from 5 to 500 free spins, with all winnings carrying a 50x wagering requirement.
- Real Money Promos: MonsterCasino keeps its promotion section lively by regularly adding real-money promotions. Current examples include Drops & Wins, the Oktoberfest Leaderboard, and the Trio of Fortune series. Drops & Wins is one of the most popular and often found as the only available promotion on competing UK casino sites. However, MonsterCasino goes further by regularly adding a variety of prize drop and leaderboard promotions. What's more is that if you win, these promotions pay in cash with no wagering requirements.
The VIP and Loyalty Program At MonsterCasino
MonsterCasino runs a Choose Your Rewards system, where your activity converts into points that can be exchanged in a rewards store. Progress is tracked through missions, levels, and leaderboards, each unlocking additional benefits.
- Missions: Complete tasks such as trying new games, claiming bonuses, or triggering slot features to earn points.
- Levels & Badges: Higher play levels unlock achievement badges tied to exclusive offers and perks.
- Leaderboards: Points and badges contribute to leaderboard rankings, with top positions earning extra prizes.
- Rewards Store: Points can be redeemed for free spins, deposit bonuses, bonus money, cashback deals, and other offers.
For VIP players, the appeal is mainly that rewards are not fixed but chosen, making it possible to prioritise free spins, cashback or bonus money depending on your playing style. It’s worth noting that many UK online casinos don’t offer any structured rewards programme, so the option to earn points and choose benefits here is a positive for mid to high roller players.
MonsterCasino Payment Methods, Withdrawal Times and Limits
MonsterCasino offers a wide range of reputable payment and withdrawal options. As with most online casinos, the minimum deposit amount varies depending on your chosen deposit method, ranging from £10 to £15. Additionally, although no fees are applied when you deposit, a small mandatory withdrawal fee is charged.
MonsterCasino Payment Methods
- Bank Transfer: Bank transfer
- E-Wallets: Neteller, Payz, PayPal, Skrill
- Digital Payment Cards: PaysafeCard, NeoSurf
- Debit Cards: Visa, MasterCard
- Mobile Payments: Apple Pay, Pay via Phone
Once you have set up your deposit, an encrypted payment window will appear and instantly process your transaction, immediately topping up your balance. Additionally, it is worth noting that, as per the UK Gambling Act 2005, credit card deposits are not permitted, which applies to all licensed online casinos in the UK.
MonsterCasino Withdrawal Times, Limits, and Fees
Although high rollers do not benefit from segregated fund protection, MonsterCasino does not apply withdrawal limits to UK accounts. Budget players are also well taken care of, thanks to a low £5.00 minimum cashout, which is one of the lowest minimum cashouts available in the country.
We did find one caveat that affects all casino members, and that is the 1% charge applied to all withdrawals up to a maximum of £3.00. With that said, we are not overly concerned, as we have reviewed other UK casinos with higher fees. To put this into perspective, if you withdraw £10.00, you'll receive £9.99, which is effectively the price of one spin on a penny slot.
Important Withdrawal T&Cs
- KYC Checks: When you first register, the casino uses automatic checks to verify your age and address. However, if that doesn't work, you will need to upload a copy of your passport or driver's licence. Furthermore, high deposits and withdrawals may trigger a request for proof of funds.
- KYC Verification Time Frame: Not mentioned
The Game Selection At MonsterCasino
We found in MonsterCasino a handful of British software providers well-known online and on the UK land-based gaming scene. These are Blueprint Gaming, Inspired and Playtech. MonsterCasino is also host to a selection of well-known online-only UK software providers, such as Realistic, Iron Dog Studio, Switch Studios, Northernlights, and 1x2 Gaming. Not a bad selection at all.
Of course, there is also a mix of international casino game developers, with Elk Studios, Scientific Games, Play'n GO, and Pragmatic Play supplying the gaming lobby with slot machines, crash games, scratch cards, and other games.
Fruit Machine Games Online - International & UK providers
Out of more than 3,000 games on the site, you can explore more than 2,500 online fruit games. The range covers every major reel mechanic, from classic paylines through to Ways to Win, Cluster Pays, Infinireels, and the ever-popular Megaways Mechanic and Pay Anywhere reel mechanics.
We checked the featured games lobby to see which duties the casino rates, and found that games across Buffalo King Megaways, Big Horsey Fortune, The Racaroon, 4 Horsement III, and 3 Porky Banks Extra are in the top five positions. If you are looking for fruitie games also available in land-based venues, some of the best games available on MonsterCasino include Cops & Robbers, Rainbow Riches, Wish Upon a Jackpot and Luck O' The Irish.
Unfortunately, our experience of navigating the gaming lobbies was less impressive than the game selection. Filters are limited to 'New', 'Featured', 'Slots', 'Casino', 'Vegas', and 'Jackpots', which, to be honest, doesn’t help much when faced with such a large library. We were able to use a search bar to find specific slot titles or providers, and we created a personal favourites lobby, but overall, the game filters are not what we would call user-friendly, which, for some reason, is standard for the majority of UK online casinos.
Some of the fruities we added to our favourite games list included:
- Rich Wilde and the Book of Dead
- Gates of Olympus 1000
- Break Da Bank Again
- Big Bass Bonanza
Just in case you are new to online casino gaming, maximum bets for fruit machines depend on your age. Under the UK Gambling Act 2005, players between 18 and 24 can set spin bets to a maximum of £2.00. If you are 25 or over, then you can place bets of £5.00 or more.
Progressive & Fixed Jackpot Casino Games
There’s no shortage of choice when it comes to jackpot fruities. In the 'Jackpot' lobby, we encountered Age of the Gods and PowerPlay networks are available. Also, a series of stand-alone progressive slots by Play'n GO, Eyecon and Playtech make an appearance.
Despite the collection of 150+ progressive jackpots, in our opinion, MonsterCasino will not appeal to serious jackpot hunters as much as competitors hosting major networks. For example, Mega Moolah, WowPot! and Jackpot King are missing and would make excellent additions.
Live Casino Games - live dealer casino table games
The live dealer games at MonsterCasino are split into familiar lobbies for roulette, blackjack, baccarat, and game shows, making it easy to sit at the type of table you prefer. Powered by Playtech and Evolution Gaming, the line-up mixes traditional favourites with more creative titles, so the live casino feels varied rather than repetitive.
Players can spin their way through Football Roulette, Quantum Roulette, or Cash Collect Roulette Live, while blackjack ranges from fast-paced tables like MegaFire Blaze Blackjack Live to high-roller action on Playtech’s SOIRE Blackjack VIP for high rollers.
Baccarat fans aren’t left out either, with standard versions alongside Baccarat Live from MGM Grand. For something different, there are live online slots such as Buffalo Blitz Live, lotto-style games like MegaFire Blaze Lucky Ball Live, and fun game shows including Spin A Win, Adventures Beyond Wonderland, and even quirkier options like Super Sick Bowl or Ice Fishing.
Sports Betting Markets - competitive odds & live betting
The sportsbook at MonsterCasino covers major markets, with football among the highlights, offering competitive odds and live betting across leagues and tournaments. Having both a casino and a sportsbook in one place means you don’t need a separate sports betting account, which is an advantage over casinos that only focus on slots and table games.
MonsterCasino Mobile App - Instant play access
Testing MonsterCasino on Chrome, Safari, and Edge showed smooth performance across devices, with no dedicated app required since play runs directly in the browser. Unlike some UK casinos that rely on separate apps, saving the login page to a homescreen provides quick access without updates. The full range of mobile casino games is available here, and players can set limits, check account history, and move between slots and live tables with the same speed and stability as desktop.
Our MonsterCasino Customer Service Review
MonsterCasino features several customer support options to help you solve any problems or answer questions. You can use the 'Help' page, full of detailed FAQ articles for self-help or contact a customer service rep via a real-time live chat or email support.
- Live Chat: Our experiences using the live chat support window were, on the whole, positive. There was one situation where we waited about 5 minutes for a support agent. However, on most other occasions, we barely had to wait for more than a minute.
- Email Support: The email address to contact the support team is [email protected].
- Complaints: You have the option to submit complaints by email to [email protected]. As per UKGC rules, the operator must acknowledge complaints within 24 hours and aim to resolve them within eight weeks. If no agreement is reached, you can escalate your case free of charge to the independent and UKGC-regulated ADR body eCOGRA.
Alternative UK iGaming Sites to MonsterCasino
To put MonsterCasino into context, we’ve compared its features directly with two other UK-based online casinos to show where it stands out and where it falls short.
_64_841.png)
MonsterCasino Vs. Playmillion Casino
The standout feature that we always remember about Playmillion casino is that the platform has an outstanding selection of game filters. Moreover, it's worth noting that there are over 6,000 games. Therefore, if you are looking for somewhere with a larger game selection and user-friendly filters designed to help you find fruities and table games with ease, thanks to excellent filters, Playmillion is worth looking into. However, MonsterCasino does win when it comes to lower wagering requirements.
MonsterCasino Vs. Duelz Casino
In stark contrast to MonsterCasino and unlike most UK iGaming platforms, Duelz builds its brand around PvP-style features where players duel, cast spells, and earn rewards through gamification. That makes it one of the few social-style platforms in the market. MonsterCasino runs a more traditional VIP and loyalty programme, but still with an element of fun as you earn points for activities and choose your own bonuses. We would say that it is less playful than Duelz, but with the benefit of steady cashback, flexible rewards, and long-term perks.
Our Opinion and Verdict on MonsterCasino
In our testing, MonsterCasino delivered a balanced experience for UK players, with a few weaknesses but also several strengths that stood out. We found the five-stage welcome bonus unusual in a market where most sites only offer a first deposit deal, while the chance to win or deposit to earn regular free spins undoubtedly works in the casino's favour. Furthermore, Drops & Wins tournaments, cash-paying leaderboards, and a flexible rewards programme also help.
The game coverage impressed us too, with over 3,000 titles including more than 2,500 fruit machines and a live casino powered by Playtech and Evolution Gaming. Having a sportsbook and a casino together in one account also felt practical, avoiding the need for separate platforms.
With all this in mind, not everything worked in MonsterCasino’s favour. Free spin winnings capped at £20 are limited compared to competitors, and the 1% withdrawal fee up to £3 is an annoyance ,even if small. We also noted that fund protection is classed as 'not protected,' which is a concern in the event of insolvency, and the limited game filters made browsing less smooth than sites like PlayMillion.
Overall, we’d consider MonsterCasino a reasonable choice if you want both casino and sportsbook play and casino promotions with reasonably fair wagering requirements. However, if your priority is faster withdrawals, stronger game filtering, or higher-value free spin conversions, other UK casinos may serve you better.
