Monster Casino

Monster Casino is an online sportsbook and casino that offers licensed betting and gameplay to the UK market. It is owned and operated by ProgressPlay, an experienced player in the industry who runs a network of other betting sites. ProgressPlay is authorised and regulated by the Malta Gaming Authority and the UK Gambling Commission, and this allows Monster Casino to offer licensed betting to UK players.

The address registered at the UKGC for ProgressPlay is Kolonakiou 26, Office No.18, Agios Athanasios, Limassol, 4103, Cyprus, under account number 39335. However, at the MGA, the registered address is Soho St. Julian’s, Office 2B, Punchbowl Centre, Elia Zammit Street, St. Julians, STJ3154, Malta, under account number MGA/B2C/231/2012. This latter address is the one that is displayed on the Monster Casino website. Therefore, if you need to contact them, it would be advisable to use these contact details rather than those listed at the UKGC.

Licensing Information

Licence Violations

Monster Casino isn’t directly registered with the UKGC, so there are no violations recorded against their name. However, their operator, ProgressPlay, was found to have breached its licence in May 2022 due to failures with its policies on anti-money laundering and socially responsible gambling.

Introduction to Monster Casino

Monster Casino launched in 2021 and offers players a popular sportsbook as well as a large and varied casino. The site is owned and operated by ProgressPlay, an established name in the industry.

ProgressPlay is registered with the MGA in Malta, where they are based. However, as the company is also authorised by the UKGC, Monster Casino is able to offer legal, licensed play to the UK market.

There are a number of online casinos in the ProgressPlay network, so there may be elements of Monster Casino that feel familiar. However, with the individual branding, there’s enough variety to ensure you don’t feel as if you’re visiting a site you’ve been to before.

Welcome Bonus

Sportsbook BonusBet £10 and receive £30 free bet
Wagering Requirementsx1
Time to Wager7 days
New Players Only. Free bet – one-time stake of £30, min odds 1.5, stake not returned. 1X wager the winnings. Wager from real balance first. Wager calculated on bonus bets only. Max conversion: £200. Valid for 7 Days from issue. Withdrawal requests voids all active/pending bonuses. Excluded Skrill & Neteller deposits. Full Terms apply. BeGambleAware.org

If you’ve not had a flutter on the sportsbook at Monster Casino before, you can sign up to take full advantage of their welcome offer.

Once you’ve created a new account at Monster, you will receive a £30 free bet after you have placed a bet for £10 yourself. The bet must have minimum odds of 1.5 to qualify.

If you net a win with your free bet, you can withdraw your winnings, minus the stake. However, you will first have to meet the wagering requirements of x1. You have seven days from the day of receipt to fulfil the wagering requirements, or else the bet will be made void.

There are certain exclusions which apply to the free bet, such as making a deposit with methods such as Skrill or Neteller. If you make a withdrawal request while the bonus is active or pending, this will also make it void. Therefore, you need to be careful to stick to the terms and conditions to ensure you get the maximum benefit from the sports welcome bonus.

Betting Markets Available

Monster Casino doesn’t aim to cover a full spectrum of sports, preferring instead to offer depth and quality on a more selected market.

You’ll find all of the popular sports betting markets are included at Monster, with the option to bet on football, rugby, cricket, basketball, and ice hockey. There are multiple leagues available for all of the sports, so you can drill down into the detail to find the team you want to bet on.

Esports aren’t yet fully available at Monster, but you can bet on League of Legends. Just select the option from the navigation panel on the left to display all of the available bets.

How To Play at Monster Casino

If you like the look of Monster Casino and would like to play at either their casino or bet on their sportsbook, you’ll have to register for an account first. This is because the UKGC requires Monster to be able to identify all of its players to comply with rules around responsible gambling and anti-money laundering.

It’s totally free to join, and the process can be completed within just a few minutes. In addition, if you’re new to the site, you can claim a lucrative welcome bonus.

Follow these steps to sign up:

Visit the Monster Casino website

Head over to the Monster Casino website and take a good look around. There’s no point registering for an account if it doesn’t offer what you want, so take full advantage of the open design of its library.

Create a new account

If you find the Monster Casino site appealing, click on the yellow “Sign Up” button to create a free account. Follow the instructions on the screen but make sure all of the details you provide are accurate because they will be verified.

Make a deposit

When your account is up and running, the first step is to make a deposit. If you want to claim the welcome bonus, you’ll need to use a payment method other than Skrill or Neteller.

Place your qualifying bet

If it’s the sportsbook welcome bonus that you’re claiming, you’ll need to place a qualifying bet to receive the bonus. Once your bet has been placed the bonus should be credited automatically, so check your account before continuing.

Monster Online Casino

Many sports bettors like to play casino games too, and at Monster, you can enjoy everything from just a single account. With an exciting online casino, it’s possible to switch between betting on sports and playing slots with just a few clicks.

Game Selection

There are more than 800 casino games available at Monster Casino, giving players a fantastic choice with both old favourites and hot new titles on offer.

Slots are one of the most popular elements of any casino, and they make up the largest section of Monster. Games are available from a wide range of top providers in the industry, so there are titles which will appeal to all. The providers include NetEnt, Playtech, Play’n GO, Microgaming, Inspired Gaming, Elk Studios, and more.

All of the common genres of slots are included in the selection, with both classic gameplay and modern themes on offer. 3D slots provide a more immersive experience, while progressive jackpot slots have the potential for huge payouts.

In addition to slots, there are traditional casino games such as roulette, blackjack, baccarat, and poker. These are available as live dealer games, which deliver a more interactive experience by allowing online chatting as you play.

All of the games are available for mobile play, giving you the option to access Monster Casino wherever you are.

Casino Welcome Bonus

One thing that can make a win even sweeter is the chance to play with free money. If you haven’t played at Monster Casino before, you’ll have the chance to claim a welcome bonus when you sign up for the first time.

The bonus is a multi-tier reward which is split over the first five deposits (of a minimum of 20 GBP each), giving up to a maximum of £1000 and 100 free spins.

  • 3rd deposit – 25% deposit match up to £200
  • 4th deposit – 25% deposit match up to £600

If you make a withdrawal request before you have completed the wagering requirements, the bonus and/or any winnings will be void. In addition, if you make the deposits using Skrill or Neteller, you will not be eligible to claim the bonus. There are other payment methods available, so you may prefer to use these for the duration of the bonus.

Summary of Monster Casino

All of the big-name providers are present at Monster, with a range of slots in different themes. The welcome bonus is generous, offering players the chance to win up to 100 spins plus free bonus cash. Whether you’re new to playing casino games or an experienced pro, you’ll find lots to enjoy at the Monster Casino.

Monster Casino Review Summary

Founded in 2021, Monster Casino is an online sportsbook and casino that is owned and operated by ProgressPlay. As a well-established operator in the market, ProgressPlay provides experience to the Monster brand.

Players can feel reassured by the fact that its operator is fully licensed and authorised by the UKGC. The site also contains lots of information about RTP and the best way to play their games, plus links to industry organisations such as GamStop.

Having both a sportsbook and a casino is a big plus, especially as the casino has more than its fair share of games. Unfortunately, the welcome bonus is slightly lower than average, and the x50 wagering requirements for the casino bonus are hard to meet.

Help is available from the customer service team via a live chat function that is online 24/7. There is also an email address for more complex enquiries. Unfortunately there is no phone number for Monster, but this is fairly common for online casinos and shouldn’t be viewed as a red flag.
