Plaza Royal Sister Sites

Renowned for its stellar reputation in the online gaming industry, Prime Slots Casino offers a diverse selection of games catering to every type of player. Established in 2011, the casino has solidified its position as one of the premier gambling sites for players from the UK, Canada, New Zealand, and beyond.

The banking system at Prime Slots Casino is not only reliable and secure but also user-friendly, featuring a range of payment options including debit/credit cards, prepaid vouchers, e-wallets, and other popular methods. However, it’s worth noting that withdrawal times could be improved.

In terms of the welcome bonus, while the offer of 123 free spins on your first deposit is decent, it’s somewhat modest. Combining spins with a match bonus would undoubtedly enhance the offer for players.

With so many UK casinos on the market, it’s worth highlighting sites like Diamond 7, which operates on the trusted White Hat Gaming platform—the same network behind well-known casinos like Jonny Jackpot and Slotnite. While Diamond 7 may not be new—it’s been around since 2015—it continues to be actively promoted and remains a solid choice for players.

This casino serves as a hub for top-tier slots and table games, featuring titles from industry-leading providers such as NetEnt, Play’n GO, and Microgaming, among others. It also supports a wide range of payment options to ensure a smooth and flexible banking experience.

There’s no reason not to take advantage of their generous welcome bonus: a 100% match up to £100 plus 100 free spins on Hotline or Fruit Spin with your first deposit.

Skol Casino is a brand operated by White Hat Gaming Limited and is licensed and regulated by both the UK Gambling Commission and the Malta Gaming Authority. With such reputable oversight, you can expect top-tier service and a quality gaming experience. Skol has clearly learned from its successful sister sites like G’Day and 21Prive.

The casino features an impressive and ever-growing catalog of games, including slots, progressive jackpots, table games, and a robust live casino section. In total, there are over 2,000 titles—more than enough to satisfy even the most enthusiastic UK players.

When it comes to bonuses, Skol rolls out the red carpet with a five-part welcome package. The first deposit gets you a 100% match up to €300 plus 100 spins. If you continue claiming the remaining offers, you could receive up to €1,300 in bonuses and 250 spins in total. UK players, on the other hand, can claim a single welcome bonus of 100% up to £100 plus 100 bonus spins on their first deposit.

Sin Spins is a great option for UK players as it belongs to a bigger company that successfully runs multiple sites including casino and sports products.

Overall, Sin Spins has a lot of positive feedback from players thanks to a superb game collection and several banking options. Withdrawal times are not the fastest but quite decent.

When it comes to bonuses, it is disappointing to see that there is a max cap on winnings from the welcome offers. Keep that in mind and grab 100% of up to a £200 bonus on your first deposit.

Due to recent instability within the company, we advise players to stay away from Regent Play and sisters until the situation is clarified.

Regent Play comes from Aspire Global which is quite a popular platform provider catering to players from the UK, Canada, New Zealand, and Europe. It is safe and trusted thanks to many years of experience in the business.

Like most of the Regent Play sisters, it offers plenty of games from leading providers, quick deposits, and entertaining promotions. Yet, we wish withdrawals were faster since it can take a few days to get it approved.

Overall, Regent Play is a decent online casino for slots fans. Check it out with an amazing welcome pack that goes up to £200/€800 packed on your first deposit.

The operator has faced several issues lately, so we recommend caution and avoiding playing at Spinrio for now. We will be happy to see the company address the issues so we can recommend Spinrio sisters again.

SpinRio is following in the footsteps of its successful sister sites, and we’re pleased to introduce another excellent casino by MarketPlay LTD. Like the sisters, SpinRio uses the Aspire Global platform. It has a lot of advantages but at the same time, it is not perfect.

SpinRio is powered by 50+ software developers which provides enough options for most players. In terms of banking, several payment options are available for quick and easy cashouts. However, when it comes to withdrawals, processing times can be longer.

New customers can try SpinRio with an amazing welcome pack starting with £200 + 100 spins on the first deposit. Note that the bonus will depend on your location.

Due to unresolved matters affecting the operator, players are advised to avoid this casino for the time being. Please visit the alternative casinos, such as Pub or Bet365.

ZetBet is quite new to the audience but since it comes from the same company as Mr Play, it is safe to assume that ZetBet will follow in the footsteps of its sister.

Since the casino is using the Aspire Global platform, it targets plenty of markets including the UK, Canada, and New Zealand. The game collection is more than decent since there are 50+ software developers. On top of that, ZetBet also offers sports betting, which is a good addition.

Your welcome bonus will depend on your location and preferences: casino or sports. But in any case, you are up to some really nice deals from ZetBet.

Recent developments (Dec 2025) raise concerns about the company’s stability, so playing at Mr Play and its sister sites is not recommended for now. You are welcome to check similar casinos below. 

Even though Mr Play was launched only a few years ago, it has managed to create a positive name for itself and has given a huge push to the rest of the sisters. The site offers both casino and sports betting experiences which is amazing news.

Being an Aspire Global white label, Mr Play has very competitive odds even in comparison to other bookmakers available in the UK, Canadian, and European markets. Additionally, you can find more than 50+ game providers that feature a good choice of slots, table games, and live dealers.

The welcome bonus isn’t so impressive but it’s still decent. The offer depends on your location but the UK gets 100% of up to a £200 bonus with additional spins.

Luckster and its sister sites are currently affected by unresolved issues, and we advise players to hold off until there is more clarity. We suggest checking alternative casinos such as bet365 or more slots focused Jonny Jackpot. 

Luckster Casino is another Aspire Global site managed by Mr Play Partners. Like some of its sisters, Luckster welcomes players to both a casino and sports betting experience, so it is perfect for those who enjoy both.

The site targets multiple locations, including the UK, Canada, and most of Europe. Thus, it is packed with convenient payment options for smooth deposits. It would be great to see faster cashout,s though.

Luckster is a good option since it combines several products into one. Based on your preferences/location, you can claim a super 100% bonus on your first deposit.
