This promotion is available for 30 days on multiple game types, including slots, classics, table, and live dealer titles. You must meet the 50x bonus playthrough conditions to cash out up to 3x bonus amount.

Casino Verdict

WatchMySpin Casino started the online activity in 2021, being part of the ProgressPlay Limited company. It has started to gain a reputation thanks to its features and commitment to improving the experience of UK players.

From over 2085 available games to downloadable mobile apps, 1-day KYC and payouts, low minimum withdrawals, a rewards program, and multiple promotions—including cashback—all these aspects make it a hunted destination. Yet, British punters should not expect fast support via phone.

Promotional Rules

Only first deposits will activate this bonus, and it’s also necessary to have your account fully verified. Onwards, a minimum deposit of £10 is necessary for this bonus.

Then, you will have to wager the bonus funds, and the latter has a 50x rollover requirement. The maximum withdrawal amount is 3 times the bonus amount. The bonus expires after 30 days.

Casino Verdict

As a Royal House Casino member, you can experience 24-hour withdrawals, a diverse selection of over 1000 slots, and 24/7 good customer service. Although the live dealer games section could be more varied, the 60 existing games still include live roulette, blackjack, and baccarat games with reasonable minimum bets starting at £0.2.

The site rewards loyal punters within the VIP club, but you can access the platform only on browsers since it lacks applications.

Bonus Details
Promotion Terms

A minimum £10 deposit is necessary to claim this bonus. Afterwards, you will have to choose the 30 free spins option and stake the deposit to qualify. No wagering requirements are attached to the bonus, but each player has to use their deposit before the spins are granted. The maximum use time is of 30 days.

Casino verdict

Virgin Games has well-explained and transparent terms and conditions. Still, we believe this section is quite cluttered, and it could use some improvements. Here, you can pay via ten different methods, a nice banking options number, and the payout takes up to three days, a long period compared to other sites.

This site will not charge fees for your transactions, which is a plus.

Pros

  • Popular providers such as Netent, Microgaming, and 28 more
  • 960 slots are available
  • No transactional charges
  • Low deposits and withdrawals of £10
  • Available app from AppStore and Google Play
  • Customer service through email and a 24/7 live chat

Cons

  • The maximum payout is £25000

Your free spins will auto-play on the first eligible game you load. Remember, the free spins expire 7 days after they’re credited. Eligibility restrictions apply, so make sure to check the full terms and conditions.

Casino verdict

Sky Vegas, available to UK players since 2008, provides a substantial gaming portfolio featuring more than 940 slot titles and a comprehensive live casino section. The site’s minimum deposit is only £5, making it accessible to most British users. However, the casino lacks a loyalty programme and 24/7 customer service, which can be inconvenient for frequent or high-stake players. The UK Gambling Commission and Alderney Gambling Control Commission licenses ensure a secure and fair gaming environment.

Pros:

  • Over 940 slot games
  • A low minimum deposit of £5
  • Quick payout times (1-2 days)
  • Licensed by UKGC and Alderney

Cons:

  • No VIP or loyalty programme
  • Customer support is not available 24/7

About Monster Casino: Why is it a Top Site?

Monster Casino is one of the top online casino sites in the UK, part of the well-renowned ProgressPlay Limited family. Established in 2017, this site offers over 700 slot games, 77 live casino games, and a myriad of bonus offers for both new and existing players. As can be seen in our review of the site, we rate Monster Casino higher than average.

Monster Casino has many great sister sites, too, that can serve as great alternatives to the site, which you can learn more about below. These sister sites include Betarno, Fruity King, Casimpo, and others.

How We Selected Monster Casino Sister Sites 

Our criteria for selecting the best Monster Casino sister sites were very strict, and we followed the same rigorous protocols for all our selections and reviews.

We looked at several factors for each and every casino site before we compiled a list of all the best sister sites. The criteria we took into consideration are as follows:

  • Company background: We looked at the history of the company that operates all these casinos and how long they have been in the works. This helped us derive the company’s values and how those are transmitted to the casinos.
  • Games portfolio: We also ensured that all the casinos we tested offered the best casino games from reputed providers. The selected games were played using real accounts, which our experts used to test all the casinos.
  • Payment methods: The availability of reliable payment methods is a huge factor for UK punters, and we took this into consideration while reviewing Monster Casino and its sister sites.
  • Available bonuses and promotions: Bonuses are a great way to keep punters engaged with an online casino, and these sites have them in abundance. We studied all the bonuses these sites offer in 2024, from the first deposit bonuses to bonuses offered to new players.
  • Customer support services: We measure a casino’s customer support system by how its agents respond to customers’ queries and how helpful they are on live chat. Monster Casino and its sister sites were also tested on this, and we were fairly impressed with what we experienced.
