Monster Casino

Monster Casino launched in 2017 and holds licenses with the UK Gambling Commission (UKGC) and Malta Gaming Authority (MGA). It stands out for its impressive volume of promotions, beginning with a large welcome bonus worth 100% up to £1,000 plus 100 free spins.

We count almost a dozen other promotions at the time of this review, with examples being free spins, leaderboard races, and deposit bonuses. By comparison, some UK-facing online casinos don’t feature any additional promos besides the welcome offer. On the downside, bonus wagering requirements are slightly high at 50x the bonus plus deposit amount. Matches on the deposit bonuses are low, typically starting at just 25%.

The Monster Casino game selection is average, featuring over 500 games. Although not the UK’s largest game variety, Monster does ensure an adequate amount. It also provides a small sportsbook that has key markets like football, rugby, cricket, boxing, and esports.

Software and Games

Monster Casino offers over 500 games from more than a dozen software providers. Examples of the latter include Big Time Gaming, ELK Studios, Evolution Gaming, Microgaming, NetEnt, and Pragmatic Play. Like many online casinos, Monster concentrates most of its selection in the slots category. Some examples of slots here include:

  • Diamond Rush Express
  • Fire Portals
  • Golden Orbs of Egypt
  • Jack Hammer 3: Diamond Affair
  • More Usual Suspects
  • Pirahna Pays
  • Sakura Masks

The only downside to the slots selection is that no filters (e.g., Megaways) are available. On the bright side, Monster does offer a search engine that lets you look up specific titles.

Other game types at this casino include scratch cards and live dealer casino games. The Monster live casino offers dozens of games, such as auto roulette, blackjack, French roulette, Baccarat Squeeze, and Blackjack Party.

Banking and Customer Service

Deposit methods at Monster Casino include Visa, Mastercard, Payz, Trustly, PayPal, Paysafecard, and MuchBetter. The withdrawal options are mostly the same, meaning you’ll have plenty of ways to cash out. The minimum deposit and withdrawal are both £10.

Customer support is available 24/7 through email and live chat. We asked a simple question through live chat and had our answer within less than a minute.

Safety and Security

This gaming site uses high-level encryption to keep your information safe from hackers. Therefore, you don’t need to worry about your banking or personal details getting stolen.

Monster Casino provides additional assurance through its UK and Malta licenses. The UKGC and MGA are two of the toughest gaming jurisdictions regarding licensing requirements and overall standards.
