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, 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. UK players can get a big higher offer of 50% up to £50 + Free Spins for 1 Year.

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 $500 plus 50 free spins on the first three deposits. If you are from the UK, there is a new interesting offer of up to 500 wager free spins.

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 up to 500 wager free spins over 14 days.

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 news about the company closure, we suggest checking some of the best casinos below.

Regent Play came from Aspire Global which was quite a popular platform provider catering to players from the UK, Canada, New Zealand, and Europe. It was safe and trusted thanks to many years of experience in the business. Like most of the Regent Play sisters, it offered plenty of games from leading providers, quick deposits, and entertaining promotions. Yet, we wish withdrawals were faster since it could take a few days to get them approved.

Regent Play was a good casino, so it is unfortunate that it has closed down.

Archive: SpinRio was 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 used the Aspire Global platform. It has a lot of advantages but at the same time, it is not perfect.

SpinRio was powered by 50+ software developers, who provided enough options for most players. In terms of banking, several payment options were available for quick and easy cashouts. However, when it came to withdrawals, processing times were long.

Due to the company closure in May 2026, we are sorry to inform you that Zetbet and its sisters have closed. Please visit the alternative casinos, such as Pub or Bet365.

ZetBet was quite new to the audience but since it came from the same company as Mr Play, it was safe to assume that ZetBet would follow in the footsteps of its sister. And it did good, before it went under.

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

Recent developments (Dec 2025) raised concerns about the company’s stability, which, not to our surprise, led to the company’s closure in May 2026. You are welcome to check similar casinos below. 

Even though Mr Play was launched only a few years ago, it has managed to build a positive reputation and given a huge boost to its sister sites. The site offered both casino and sports betting experiences.

As an Aspire Global white-label, Mr Play had very competitive odds, even compared to other bookmakers in the UK, Canadian, and European markets.

You can find great and safe alternatives below, which offer similar things and more. 

Luckster and its sister sites are no longer available since 3rd of May 2026. The company announced its closure, so we suggest checking alternative casinos such as bet365 or more slots-focused Skol Casino. 

Archive: Luckster Casino was another Aspire Global site managed by Mr Play Partners. Like some of its sisters, Luckster welcomed players to both a casino and sports betting experience, so it was perfect for those who enjoy both. The site targeted multiple locations, including the UK, Canada, and most of Europe. Thus, it was packed with convenient payment options for smooth deposits.

So, it is sad to see it being closed as originally it looked very promising.
