Monster Casino Review

Monster Casino is a bright and colourful online casino with a lot to offer. Despite its name, it’s not scary and creepy – in fact, it’s more of a welcoming and friendly casino than anything. It’s aimed at beginners just as much as experienced players and has lots of useful information readily available. There are several hundred games waiting to be played, including video slots, live dealer games, scratchcards and casino games, with most of them playable on mobiles. There’s an app available on iOS devices that offers most of the casino’s games. The operators take the wellbeing of all players seriously and use the latest security software to keep everything safe.

Monster Casino Review

Monster Casino came roaring and stomping into the UK gaming market in 2017, and it looks like being around for a while. The Casino Gorilla is always more than a little sceptical about sites which advertise themselves as ‘the best online casino’, but he understands that sometimes a little self-promotion is required. Of course, our hairy reviewer makes his own assessments and he has seen many many online casinos come and go over the years. This British-focused site will certainly attract attention thanks to its free no-deposit bonus offer, but let’s see what else the Casino Gorilla discovered on his tour of the site.

  • Good Variety Of Slots
  • Very Secure
  • Mobile-Friendly Site Design
  • High Wagering Requirements
  • Only UK Players Accepted

Monster Casino Welcome Bonus

Surely any offer which gives players money for nothing has to be a good deal, right? Well the Casino Gorilla scoured the small print of the welcome package for new players and he certainly did not like everything he discovered. For example, that free fiver for registration is all well and good, but it is only available for use on 3 slots, it has to be wagered 100 times and winnings are capped at just £20. Definitely not as generous as it first seemed. The matched deposit bonuses have lots of conditions attached as well, such as a very, very steep wagering requirement of 40 times the deposit plus bonus and just 28 days to complete that wagering. There is also a long list of games which don’t count towards completing that wagering. This offer looks good on the surface, but is far less attractive than it first appears.

Monster Casino Bonus Terms and Conditions:
  1. Free £5 welcome no-deposit bonus
  2. 100x wagering requirement on this bonus
  3. Only available for use on Shamrock N Roll, Mayan Marvels and Candy Swap
  4. Max winnings £20
  5. 200% matching deposit bonus on first deposit up to £50 with 50 free spins
  6. 100% matching deposit bonus on second deposit up to £200
  7. 50% matching deposit bonus on third deposit up to £250
  8. Minimum deposit to claim match bonus £10
  9. Wagering requirement 40x deposit plus bonus
  10. Bonus valid for 28 days once claimed
  11. Bonus winnings capped at 4x bonus amount

Monster Casino Free Spins

When you make your initial deposit of at least £10 with Monster Casino you will be given 50 free spins on the ever-popular Starburst slot game. The free spins are worth 10p each and will be available automatically once you enter the Starburst game. Anything won from those spins must be wagered 40 times in order to make them withdrawable.

Bonus Code

It is not necessary to enter a bonus code in order to claim any of these new player awards from Monster Casino. All bonuses will automatically be added, first by registering with the site from the UK and then by making the three qualifying deposits. If you need to enter any codes to avail of future bonus offers then you will be notified in the text of the offer or by email.

Slot Games

Monster Casino provide players with a range of different slot gaming options from many different providers. NetEnt are popular with gamers all over the world, and some of their classic slots are available here. Plus you will find titles from other big-name providers such as Australia’s Aristocrat Gaming, plus IGT and NextGen as well. There are hundreds of slots to choose from, and the Gorilla is always glad to see a mix of games from different developers as that tends to keep the gaming experience fresh, since each developer puts their own unique stamps onto games. Here are some of the more popular slots available at Monster Casino:

  • Ted
  • Cleopatra
  • Bonanza Megaways
  • Fluffy Favourites
  • Vikings Go Berzerk
  • Finn and the Swirly Spin
  • Thunderstruck 2
  • Rainbow Riches Pick n Mix
  • Wolf Run
  • The Pig Wizard
  • Slots o Gold

Live Games

Monster Casino does a good job of offering lots of different live dealer casino options to its players. There are around 30 tables to choose from, and while most of these offer variations of blackjack or roulette, there are some alternative gaming options out there too. Those options include baccarat, casino poker, Dragon Tiger, Caribbean poker, 3 Card Poker, Dream Catcher and Football Studio. It is a fine collection of games which will keep even the most avid live dealer casino fan happy.

Mobile Gaming

Like any modern online casino, Monster Casino is perfectly adapted to be played on mobile devices like phones and tablets, as well as desktop devices. Simply fire up your Android or Apple device and you can enter the name of the site in your browser to get started, just as you would if using a computer. A wide selection of games are available on the mobile version of the casino, meaning you can play top casino games for real money no matter where you are.


The list of available payment methods at Monster Casino is long enough to ensure that everyone will be able to make a quick and easy deposit. All of these methods are free except for Boku, where a 15% charge is imposed on any deposit. The minimum deposit amount is £10, again with the exception of Boku which has a £15 minimum. You can make one withdrawal per 24-hour period, and this withdrawal must be between £20 and £2,000. Players are required to withdraw funds to the same account which they made a deposit with, whenever this is possible.

  • Mastercard
  • Visa
  • Skrill
  • Neteller
  • Paysafecard
  • Trustly
  • Giropay
  • Zimpler
  • Bank transfer
  • iDeal
  • Sofort
  • Boku

Security and Fairness

The security processes in place at Monster Casino follow best practice for the industry as laid out by the British and Gibraltar governing bodies. Customer money is stored in a separate bank account and all financial transactions are safe and secured so that nobody can access this or other personal information.


Many questions will be answered in the large FAQ section, including how to make deposits and withdrawals with specific payment methods. Click on the support button on the top of your screen if you need more personalised assistance. Customer support is available between the hours of 8am and midnight, and you can get in touch via email, live chat or telephone. Email queries will receive a response within 24 hours. Monster Casino’s offices are physically located in Gibraltar, and if you wish you can even address correspondence by old-fashioned snail mail.

Restricted Countries

Monster Casino may be primarily aimed at a UK audience, but it does still accept players from a number of other countries too. If you are resident in one of the following territories you will be able to sign up and play with Monster: UK, Ireland, Sweden, New Zealand, Canada, Norway, and Germany.


Monster Casino is a nice UK-friendly online casino with a good range of different gaming options, including a well-stocked live dealer casino. The welcome bonus offer certainly looks tempting, although on closer inspection there are a whole lot of terms and conditions which end up making this bonus a lot less beneficial than it seems to be. All in all Monster Casino is not a bad option for a player looking to open a new casino account, the Gorilla is just a little disappointed with the super-high wagering requirements which make profiting from their bonus offer a real long-shot.

Despite its name, this casino is actually quite bright and eye-catching. It’s got some pretty good games and the bonuses are quite generous as well. I’ve enjoyed playing lots of brilliant games here and recommend downloading the app.

Too many conditions attached to everything. But there is a reason they have been doing business for over 2 years. They offer the best games and live dealers from reputed providers all over the world. There are free spins as well.

One of my favourite online casinos. You might think from its name that it’s dark and horror-themed, but it’s not at all. The game selection is pretty good and the welcome offer is really generous. Love playing on my iPhone through the app. Never had any problems here thankfully.

Monster Casino is one of those operators that are mostly focusing on the mobile market, which is in my opinion a good idea. I love the place and cant get enough of the smooth interface on my phone.

Thank you for your comment. Mobile Casinos are a dime a dozen, but mobile casinos that actually work well are very rare, so it's good that you enjoy Monster Casino, as they actually made it work.
