Monster Casino Review 2025

Monster Casino is not a casino monster you have to fear. In fact, this Monster is especially friendly and generous – ready to welcome new players with very lucrative bonuses.

New players signing up at Monster Casino can choose between two welcome packages, for casino or sport.

Not many online casinos can match the bonuses at Monster and luckily, the casino scores high on other criteria too. The game selection has thousands of games to check out, including an impressive selection of scratch cards and instant-win games. There is also a sportsbook section with lots of bets waiting to be placed.

The casino can be accessed via desktop or mobile and players who prefer playing from their phone can download the Monster Casino app for easy access. Should any questions arise, customer support is available 24/7. There really isn’t much to miss at this online casino!

In-Depth Monster Casino Review

Monster Casino is an online casino and sportsbook that has been around since 2021. The casino holds licenses from the UK Gambling Commission and Malta Gaming Authority. This ensures a safe and legal gambling experience for British players. In fact, the casino is created for UK players specifically – although players from many other countries are also welcome.

New players signing up at this casino have a lot to look forward to. Not only is the game selection extensive with some unique titles and game categories, but the bonuses being offered are some of the best you’ll find.

Keep reading my Monster Casino review for all the details!

Monster Casino Bonus

Monster Casino knows that all online casino players love a good casino bonus. That is why they are offering loads of promotions, including two different bonuses for new sign-ups.

Monster Welcome Bonus

The bonus Monster Casino offers to new players is a choice between two offers:

1. Casino Welcome Package

Monster offers a “regular welcome bonus” in the form of a welcome package. Most casinos will only add a bonus on your very first deposit, but Monster offers a full package that is given on your 5 first deposits.

The welcome bonuses will give you a head start with extra spins and money to play for. You can get a maximum of up to £1,000 and 100 free spins by depositing a minimum of £20 five times. Your first and fifth deposits will give 50 free spins each, while the second, third and fourth deposit comes with a 25% match up to £200, £200 and £600 respectively.

Significant Bonus Terms

• Minimum deposit: £20 (x5)
• Monster Casino bonus code: None needed
• Wagering requirements: x50

New Players Only. Wagering occurs from real balance first. 50X wagering the bonus. Contribution may vary per game. Available on selected games only. The wagering requirement is calculated on bonus bets only. Bonus valid 30 Days from receipt / Free spins valid 7 days from receipt. Max conversion: 3 X the bonus amount. Limited to 5 brands within the ProgressPlay network. Withdrawal requests void all active/pending bonuses. Skrill and Neteller deposits are excluded. Full Terms Apply. 18+ | BeGambleAware | #AD

2. Sports Welcome Bonus

Monster Casino also has a sportsbook section. If you sign up with the aim to start by betting on sports, or you are more of a sports fan, then the sports welcome bonus is for you. By depositing a minimum of £10 and placing a qualifying bet of the same amount, you can get a £30 free bet. This free bet can be used to place a one-time stake with a minimum odds of 1.5.

Monster Casino Free Spins and Other Promotions

If you want to enjoy some free spins, you are in luck as the casino offers free spins to both new and seasoned players. It all starts with the welcome package, which in addition to offering a cash bonus on the first three deposits, comes with 100 free spins.

For more free spins, keep an eye on the promotions page for exclusive promotions. Among others, the casino offers weekly spins through a “Saturday Spinner” promotion. There are also monthly offers and lots of rewards available to claim.

Of course, it is not only new players who get to enjoy fun and lucrative bonuses at Monster Casino. Once you have played through the welcome package, you can look forward to weekly, seasonal and random promotions. The bonuses range from free spins to top-up bonuses, free money and more.

Game Selection

Just as important as the bonuses, are the casino games on offer. Luckily, Monster has a lot on offer in this department as well.

Casino Games

If you want to play a game, simply head to the game selection and start browsing. There is a lot available, but luckily the lobby is neatly divided into different categories and filters.

You can browse through categories such as Featured, New Games and Casual, in addition to different game types (slots, live, casino etc). You can also choose to show games from specific game providers only. The games on offer are from some of the best casino game developers out there, including NetEnt, Microgaming, and Red Tiger.

The majority of the games on offer are slots – the favourite category of most online casino players. Of course, classic casino games such as Roulette and Blackjack are available too, as well as some live casino titles. There are also a lot of scratch cards, for the players that prefer instant wins. All in all, this results in a varied selection with something for every player.

Live Casino

In the live dealer category, you will find all the casino classics in a new format – thanks to live streaming from game studios. Instead of playing a machine-generated and automated game, you get to play against real dealers and other players.

The live casino games at Monster Casino are all from Evolution Gaming. The selection is not the largest I’ve seen, but you have a good mix of classic versions and some newer games.

Sports

In addition to the many different casino games, you can also place bets on ongoing and upcoming sporting events.

By opening the sports section from the main category, you will be introduced to a selection of bets waiting to be placed on various sports. Here you can filter by a specific sport, add events as favourites, and check live updates on odds. If you want to make a bet, simply click on any odds to add them to your bet slip and add your wager.

Deposit and Withdrawals

At Monster Casino UK, players are free to make use of the most popular payment methods.

If you prefer to use a debit card, Visa, Mastercard and Maestro are accepted. You can also choose e-wallets such as Skrill and PayPal.

But in addition to these standard additions, there are some more modern solutions offered that will make many players happy. This includes PayviaPhone – a method directly linked to your phone bill plan. You can also make use of Apple Pay from your mobile, or opt for anonymity with Paysafecard.

Please note: Due to the Gambling Commission’s ban on credit cards as payment methods for online gambling, credit cards are no longer accepted as a payment method for UK players.

Depositing Funds

For your Monster Casino deposit, you can choose freely from the accepted payment methods. Simply log in to your account, open the Cashier and click to make a deposit. No matter which payment method you choose, all deposits are processed right away. The minimum deposit required is £10, but note that you will need to deposit £20 to get the welcome bonus.

Withdrawing Funds

When you wish to withdraw your winnings, you can in most cases make use of the same payment option as your deposit. Please note that normally, the method you used for your deposit is automatically chosen for your withdrawal too. The processing time will depend on the chosen payment method.

If you want a quick withdrawal, I recommend using an e-wallet or Trustly. A small processing fee will be added to your request, of 1% up to a max of £3 per withdrawal.

Customer Service

Should you require any assistance while playing at Monster Casino, the customer support team is available to assist 24/7.

It is easy to get in touch with Monster Casino. First of all, they have an FAQ section in place if you have a common question. If you are not able to find the information you need from the FAQ or this review, you can contact the casino via live chat or email. The easiest is of course live chat, where you can expect a quick and friendly reply within a few minutes.

When testing the casino, there was a waiting time of 10 minutes, but after that, I got exactly the information I was looking for.

Monster Mobile Casino

Are you interested in playing Monster Casino on mobile? Luckily, that is not a problem at all. Monster is yet another mobile casino UK players can enjoy from any device they prefer, including smartphones and tablets.

When playing on mobile, you can choose if you want to play from the Monster Casino app or directly in your mobile browser. The Monster Casino mobile app is available to download from App Store and Google Play. But the mobile version of the website is also easy to navigate with all games and promotions available, so you don’t have to download an app.

Navigating the Mobile Version of Monster Casino

Even when accessing the site from a smaller screen, it is very easy to find everything you need. The modern and bright design helps to keep it all clear, and large buttons give you the main choices. On the top-left corner of the screen, you’ll see a collapsable menu. On the top-right corner, you’ll find information and customer support. And on the bottom of the screen, you can sign up/log in.

Pay with Mobile Casino

If you wish, you can also make a mobile casino deposit or withdrawal request. Simply open the casino site and deposit from the mobile casino using the same payment methods as available on the desktop version.
