Monster Casino Review (2026) - Large Slots Library

Monster Casino launched with the stated aim of providing 'quality entertainment' in a 'safe, fun, fair, regulated, secure and enjoyable environment'.

They have since built up a considerable library of more than 2,500 casino games, including 2,000+ slots and an extensive selection of table games, scratchcards and live dealer options.

My in-depth review will cover all the bases - to find the good and the bad.

Monster Casino is operated by ProgressPlay Ltd, a prolific UK casino provider who run dozens of casino sites, including Casino Kings and Fruity King.

This site is licensed and regulated by the UK Gambling Commission - licence no. 39335.

Monster Casino offers new players a welcome bonus of 100% up to £50 and 30 Free Spins on Big Bass Bonanza.

Is the Monster Casino Bonus Worth It?

While this might not be the most generous bonus offer in the UK, it is still definitely worth claiming.

Offering a modest deposit-match bonus and 30 free spins for a top slot game is a great way to get started at a new casino.

Key Benefits:

✔️ Low Wagering - Players have to turn this bonus just 10 times before it can be withdrawn as real cash

✔️ Top Slot Free Spins - The free spins are for the hugely popular slot game, Big Bass Bonanza

Who is This Bonus Best For?

✔️ This is a low-value bonus that should have widespread appeal.

After playing through the welcome bonus, players have other promotions that reward ongoing loyalty.

You can launch the Wheel of Spins, which randomly awards between five and 500 free spins to use on selected games.

They also offer a generous VIP program, which awards points as you complete missions on-site. As you climb the leaderboards and level up, you can redeem these points for bonuses, free spins, cashback and more.

The most popular payment methods accepted include Visa, Mastercard, PayPal, Apple Pay, Skrill and Neteller (remember that these latter e-wallets are exempt from the welcome bonus).

Those same payment methods are available for withdrawals, as well as bank transfer. 

Although Monster Casino doesn't offer instant withdrawals, many Skrill and Neteller cash out requests are completed within 24 hours.

Any new players will need to complete a KYC verification process when joining this casino.

Before you are able to deposit, you will need to supply Monster Casino with a proof of identity document (passport, driving licence etc), as well as proof of your address (utility bill, bank statement, debit card statement etc). This must be dated no longer than three months prior to account registration.

These documents can be uploaded via your account dashboard. Players will receive an email once these have been approved.

While this process can take a few minutes, it's actually a reassuring sign, because all new sites need to verify customers in order to gain a UK licence.

There's more than 2,500 games to discover at Monster Casino, with in excess of 2,000 slots making up the bulk of the lobby.

Extensive Slots Collection

The layout of the slot lobby isn't particularly helpful, but it's well worth using the search bar to see if your favourites are here given the huge range of games available.

Starburst, Gonzo's Quest, Fishin' Frenzy and Rainbow Riches are just some of the classic online casino games on offer, alongside video slots and some progressive jackpot titles, like Odds of the Gods.

These online slots are provided by an array of developers, including NetEnt, Microgaming, Play'n GO, ELK Studios and more besides.

Solid Range of Live Dealer Tables

Monster Casino offers more than 100 live casino tables from Evolution Gaming and Playtech Live.

These cover the usual suspects - blackjack, roulette and baccarat mainly - but with different play styles and limits available. For example, there's European, French, Lightning, Multi Wheel and VIP roulette.

Other options include Dragon Tiger and Three Card Poker.

Plenty of Classic Blackjack and Roulette Games

Players who prefer classic RNG table games will find more than 25 of them here.

Beyond the usual mix of blackjack and roulette variants, they also offer baccarat, hi-lo and video poker games.

Stacks of Scratchcards

Monster Casino has 25 different scratchcard games to explore, with sports, nature and seasonal themes prominent.

At the time of writing this Monster Casino review, no mobile casino app was available for iOS mobile devices.

However, you can download a dedicated app for Android smartphones and tablets. This features hundreds of games and looks good on smaller screens... even though it is a re-sized version of the main website.

Other Android users are less bullish about the Monster Casino app, with an average score of 2.4* from 29 reviews at the time of writing. That said, some of these should be taken with a pinch of salt, as there were complaints and low scores about the wagering requirements - perhaps some players were unaware of these in advance.
