Monster Casino offers a monster collection of games, including many of the UK’s most-loved online slots. The site first went live in 2017 and is operated by ProgressPlay Limited, which is fully licensed by the UK Gambling Commission.
With over 6,000 games available, you’ll have plenty of options when you join this online casino. What’s more, Monster Casino has some fantastic bonuses, including a welcome package worth more than £1,000. Discover all the details on games, bonuses, payments and more in our Monster Casino review.
Game Types
Monster Casino offers a vast collection of games, totalling 6,069. From the main casino lobby, you can browse categories including new games, featured, slots, live casino, Vegas, jackpots and casual.
Selecting any category loads the full collection of that game type. Unfortunately, there’s a lack of secondary categories on each game type page, so you’ll have to scroll through the entire collection to find what you’re looking for. However, you can also use Monster Casino’s search to look up specific games or providers.
Some of the best game providers in the industry are featured at Monster Casino, including:
There are over 4,000 slots at Monster Casino, including hugely popular games like Book of Dead, Big Bass Splash and Starburst. While there are plenty of games to choose from, they unfortunately aren’t divided into separate categories. As a result, you’ll either have to search for a specific game or scroll through the entire collection to find a game you’d like to play.
Jackpot slots are also offered at Monster Casino, with over 190 games like CoinFall: The Big Free, Clover Rollover Star Trail and Age of the Gods Amazon Wild all available. These slots offer massive potential wins, with the current jackpot shown in the thumbnail for some games.
Table Games
The traditional casino experience is available to enjoy at Monster Casino too. There are lots of interesting versions of classic table casino games like blackjack and roulette, including Breaking Bad roulette, 3D blackjack and 9 Masks of Fire Roulette. You can also play video poker and baccarat.
Live Dealer
Live games offer a fully immersive online casino experience, and there are more than 1,000 options to choose from at Monster Casino. The live dealer section is split into roulette, blackjack, baccarat and game show categories. These are all supplied by top live game studios, Playtech and Evolution.
