Monster Casino Review

What do you think a relatively new online casino that calls itself Monster should deliver? The first thing we thought when we saw its logo and name was “there better be a monster welcome bonus to back this up”. And, boy, is there. More about that later, but in this review of Monster casino we want to look at all aspects of its offering. Is it reliable and secure? Does it have a good range of different types of games available? What are its deposit and withdrawal policies like?

For all of this and much, much more, read on for our full Monster casino review.

Monster Casino Welcome Bonus

Lets cut to the chase, then. We’ve mentioned this casino’s welcome bonus is definitely worthy of being classed as “monster”, but just how monster is it? Well, it’s not every day that you find a casino willing to throw as much as £1000 and 100 bonus spins into a sign-up package, but that’s what we’re dealing with here. Monster have bundled up 5 bonuses across your first 5 deposits that even individually would have been considered on the upper end of the generous scale. But, collated together, they amount to a very sizeable offer indeed.

  • Deposit 1 : Here you get 50 free spins on Book of Dead. Hey, it’s not a NetEnt game but lots of people love it!
  • Deposit 2 : 25% Up to £200
  • Deposit 3: 25% Up to £200
  • Deposit 4: 25% Up to £600
  • Deposit 5: 50 free spins on Starburst – they saved the best until last, in our opinion; free spins on the greatest slots games of all time!

There are, of course, terms and conditions here. The minimum deposit each time is £20 (but that’s the minimum deposit full stop at this casino) and there is a 50x wagering requirement on the bonus funds. But, even so, this is one of the biggest welcome bonuses we’ve ever reviewed.


How to Open an Account

If you’re already itching to sign up and give Monster casino a try for yourself, fear not as the registration process is very simple and speedy.

Step 1: Click on the ‘Join Now’ button on the top right hand corner (if you’re visiting on a desktop computer) or, on mobile, open the burger menu in the top left and then click “Join Now”

Step 2: The first step to creating your account is to enter your email, set a password and then add your mobile number too 

Step 3: In the Registration section, you will be required to enter your first and surname, gender, date of birth, home address, occupation and select a currency. If you have a Bonus Code then this is also the stage you enter it

Step 4: After clicking Submit, you will now be able to make your first deposit and claim your sign-up bonus  or, if you wish, you can browse around the lobby beforehand.

Step 5: That’s it, all done! Deposit some funds, get that bonus and start playing the games!

Monster Casino Promotions

As if up to £1000 and 100 free spins wasn’t enough across your first five deposits, the clever guys at Monster have also delivered a huge rostrum of other promotions and loyaltly rewards to keep their players on board.

Rewards Programme

Unlike many online casinos, Monster’s Rewards Programme isn’t dangled in front of you until you’ve deposited a ridiculous amount of money and played for hours on end. No, you start earning points almost immediately and thanks to the innovative “mission” tasks (think achievement points in a videogame) it won’t take long before you seeing points in your wallet. These points can be redeemed for things like Free Bets, Bonus Money, Match Deposit Bonuses or Free Spins.

December Festive Calendar

At the point of writing this review, the festive period was in full swing and Monster casino certainly weren’t shy of getting under the mistletoe. They had a catalogue of bonus offers longer than a 10-year-old’s list to Santa, including:

  • Happy Holidays – Up to £1,500 in Bonuses + 360 Free Spins
  • Jingle Wins Leaderboard – Make it a Merry Christmas
  • Christmas Candy – 2x 25% Up to £500
  • Midweek Cashback – claim up to 10% cashback on deposit losses
  • Thursday Slots Party Leaderboard – Festive slots tournament where you could win cash prizes
  • Friday Points Boost – Get more points (so, more rewards!) in the rewards programme described above
  • Festive Funday – 2 x 20% Up to £500
  • Christmas Gifts Galore – Up to 15 reward points for each Christmas themed mission completed
  • Hello 2022 – Celebrate the New Year with Monster casino

Now, if that little lot’s not much better than a pair of socks and a turkey sandwich, then we don’t know what is!

Payment Methods

You can probably tell that Monster casino is definitely leaning towards going in our good-books when it comes to casinos to enjoy NetEnt’s finest, but that could all fall down instantly if the payment methods offered aren’t up to scratch. But, again, Monster have pulled it off with a varied and exhaustive list of options.


  • Visa
  • MasterCard
  • Maestro
  • Paypal
  • Pay by Phone
  • Paysafecard
  • MuchBetter
  • interac
  • Bitcoin BitBayPay
  • Skrill
  • Trustly
  • ecoPayz
  • Neteller
  • UPI
  • Netbanking
  • EUTeller

While all of our test deposits went through immediately, we did note that all withdrawals are subject to a mandatory 3-day “Pending Period” and a processing fee of £2.50. Not a deal breaker by any stretch, but worth adding to your considerations when looking for a new casino to play at.

Monster Casino Game Providers and Games

We’re here for the NetEnt games, right? Well, rest assured we’ve got those covered off at Monster. But, alongside those they also offer titles from all of the biggest players including BTG, Evolution, and Red Tiger (all NetEnt’s sister companies too). There is also a nice category in the lobby called “Casual” which caters for maybe the less experienced online casino player. This selection of simpler, easier to grasp games are a great idea of introducing someone to the fun of casino games without overawing them with all of the technicalities and functions of, say, a Megaways game.

Monster Casino Live Casino

As well as the slots and casual games, Monster also has a healthy contingent of live dealer games, with many from Evolution who, of course, own NetEnt.

Monster Casino on Mobile

A casino can be great on desktop and laptops, but if it’s not mobile-responsive these days it is just not going to cut the mustard. But Monster is absolutely perfect on the smaller screen. It’s clutter free and easy to navigate around – we found it a doddle to play here even while on the move.

Monster Casino Support

Everything as you’d expect is present and correct here. An email address easily findable (no clicking through endless links in the footer with this casino), 24/7 live chat with helpful and knowledgable staff plus there is even a UK telephone number too. Its highly unlikely in our experience that you will come across any issues with this casino whatsoever but, just in case you do, it’s great to know that they go above and beyond in order to help you.

What We Like About Britain Bet

The enormous welcome package! No, there’s so much more to this casino than that. Even if they weren’t offering such eye-watering sign up bonuses, we’d still heartily recommend Monster casino as somewhere to spend some time with NetEnt’s greatest games.
