The Online Casino sister sites include BetNeo, Anytime Casino, Watch My Spin, Scorching Slots, Pots Of Luck, and Monster Casino.

The Online Casino ( is part of ProgressPlay, a firm registered with the UK's Gambling Commission under account number 39335. ProgressPlay Limited operates 94 sister sites from its official address at Kolonakiou 26,Office No.18, Agios Athanasios, Limassol, 4103, Cyprus.

The Online Casino Sister Sites

The Online Casino has numerous sister sites, all of which you can find further down in our review. We’ve also listed six of our favourite The Online Casino sister sites here with information on their promotions, games, payment options, design, and more. Check them out below:

Mr SuperPlay

Mr SuperPlay is an online casino brand run by ProgressPlay. It’s one of the operator’s better-looking sites, with a grey and green colour scheme and a straightforward user interface. New players who sign up with the casino can claim a 150% deposit match bonus of up to £50 with 30 free spins on Merlin’s Grimoire, a popular slot from Play’n GO.

We love the variety of payment methods available at Mr SuperPlay Casino, as it accepts debit cards, PayPal, Apple Pay, Payviaphone, Paysafecard, Skrill, Neosurf, Neteller, AstroPay, Payz, and so many others. Everything can be used for fast deposits and withdrawals, making it easy to start playing and enjoy your winnings. What also caught our eye were the numerous games you can play, the mobile-friendliness of the site, and the great customer support.


If you prefer a blue and white colour scheme, you may find Casimpo easier on the eyes. Once again, ProgressPlay delivers a sweet and simple website that gives The Online Casino a run for its money. Casimpo’s welcome offer consists of three free spins promotions. Your first and third deposits award 50 free spins, while your second deposit grants a batch of 25 spins. You can only use the spins on the famous Book Of Dead slot, and the welcome package has strict terms and conditions.

The available games and promotions exceeded our expectations, placing Casimpo Casino comfortably ahead of its rivals. The additional promotions include regular free spins, deposit match bonuses, a loyalty scheme, cashback promotions, and so much more to encourage you to play regularly. Casimpo also provides a top-notch mobile experience as you can download the Casimpo app for smartphones or play in-browser on all other devices.

Monster Casino

Another online casino worth considering is Monster Casino. The website is fully licensed by the UK Gambling Commission and comes with a five-part welcome bonus. Your first and fifth deposits offer 50 free spins on Book Of Dead and Starburst, respectively. Your second and third deposits are matched with a 25% bonus of up to £200, while the fourth deposit gets a 25% match bonus of up to £600.

Like Casimpo, Monster Casino is home to dozens of exciting promotions, but its games are where the website really shines. You can enjoy video slots, table games, live casino titles, jackpots, and scratchcards, all of which are powered by developers like Red Tiger Gaming, Play’n GO, NetEnt, Pragmatic Play, and more. There’s a lot of variety available at Monster Casino, so don’t expect to get bored while playing here!

Kimo Casino

If you want a ProgressPlay Casino with a darker colour scheme, we recommend Kimo Casino. The website looks great, is easy to navigate, and has an attractive welcome package to boot. Deposit £10 or more to receive a 100% match of up to £200 and 30 free spins on the Book Of Dead slot. Much like the other brands we’ve listed here, Kimo Casino accepts several popular payment methods, offers a great selection of promotions for new and long-term players, and is home to a plethora of casino content.

Our favourite aspect of Kimo Casino is its rewards programme, which offers missions for you to complete. Each completed mission increases your loyalty level, unlocking exclusive offers and advantages. You also earn points while playing on the website, which can be redeemed for free spins, deposit bonuses, cashback promotions, and more.

Mr Mobi

Mr Mobi is one of ProgressPlay’s older online casinos. It was launched in 2016 and quickly became one of the operator’s biggest brands. Part of its success stems from the welcome package, as new players can claim a £50 bonus with 20 free spins on Sparky & Shortz, a fun sci-fi-themed video slot. As a ProgressPlay brand,  Mr Mobi offers an excellent experience through its games, promotions, and speedy payment options.

On top of that, Mr Mobi Casino has one of the best customer support teams within the gambling industry. You can contact the team via live chat and email, with the former providing faster responses. The team are available 24/7, so there’s always someone on hand to help. There’s also an extensive FAQ, which lists common issues you may run into or questions and provides lots of handy advice – a great starting point if you run into a problem!

Glimmer Casino

Our final suggestion for a replacement for The Online Casino is Glimmer Casino. The website features fan favourite casino games and a sportsbook for players who prefer something different. When it comes to promotions, you can choose between a £10 free sports bet and a £100 casino bonus with 20 spins on Book Of Dead. In terms of the online casino, all of the usual games can be enjoyed, as well as several casino-based promotions.

When it comes to sports betting, you can wager on dozens of sports games and events, as well as political and cultural events like reality television shows. Glimmer Casino also has a world-class responsible gambling program. With it, you can set deposit, loss, and wagering limits, take small breaks, or self-exclude for longer periods. By using these tools, you can stay in control of your gambling.
