The Online Casino Review 2025

Founded in 2020, the confusingly named TheOnlineCasino was created to provide a high-quality entertainment platform for fans of online gambling. The site is fully licensed by the UKGC and MGA, providing players with a safe, secure, and regulated environment to enjoy their favourite games. The site is operated by ProgressPlay Limited and offers more than 1,700 casino games.

To see if TheOnlineCasino has earned the title of “the” online casino, we created an account to research what it has to offer. After conducting a thorough evaluation, we used the information we gathered to create this in-depth TheOnlineCasino review.

Like most new casinos, TheOnlineCasino website uses a dark theme with blue and green as its primary colours. Having used the site extensively, we think that this colour scheme works well; the grey-ish blue provides a neutral backdrop which makes the green icons and text stand out on the screen.

We were also impressed by the layout of the site. All of the important features, such as deposits, games, promotions, and FAQs are all available within one click of the home page. Navigating around the site is easy to do; buttons are responsive and loading times are extremely short, making for a positive casino experience.

TheOnlineCasino features more than 1,700 games that cover a variety of gaming genres, including slots, table games, live casino games, and bingo.

The site also has a helpful search function that lets you look for game titles and software providers. That being said, we’d like to see TheOnlineCasino add filtering options, making it easier to browse your favourite games.

• Slots – The majority of TheOnlineCasino’s game library is comprised of its online slots portfolio. The site has well over 1,200 unique slot games, including a variety of Megaways slots, Jackpot slots, and video slots.
  
• Live Casino – TheOnlineCasino has dozens of live dealer casino games to choose from, offering a selection of classic table games like blackjack and roulette as well as modern game shows, such as Monopoly Live and Crazy Balls.
  
• Bingo – The site has a dedicated Bingo platform offering more than a dozen rooms with tickets starting from as little as £0.01. There are 90-ball, 80-ball, and 75-ball games to enjoy, with jackpots exceeding £10,000.

TheOnlineCasino offers a generous welcome package as well as a variety of bonuses and promotions to both its existing players. To provide insight into the types of offers available, we’ve explored the most popular promotions in more detail:

Welcome Bonus

Available to every new player who joins TheOnlineCasino, the welcome package offers a 100% matched deposit bonus worth up to £100 plus 20 free spins on the popular Book of Dead slot when you deposit £10 or more. However, this bonus comes with 50x wagering requirements, making it hard to convert your rewards to real money. 

Up To 75 Free Spins

Existing players can use the code RHINO up to three times to receive 25 free spins on Great Rhino Megaways. Simply deposit £10 or more and use the promo code to receive your spins. All winnings from the free spins must be wagered 50x before they’re converted to your real money balance.

Rewards Programme

TheOnlineCasino offers a rewards programme to each existing player, offering rewards based on your play. Earn points by playing real money games and completing missions and work your way up the ranks to unlock more rewards. You can also redeem your points in the Rewards Store, receiving free spins, cashback deals, bonus funds, and more.

One of the best features of TheOnlineCasino is its range of banking options. There are more than 10 payment options available to choose from, giving you complete flexibility when funding your account. The site also offers a range of withdrawal methods, making it easy to withdraw your funds. We also liked that the minimum withdrawal amount was £5, as it makes the site more accessible to low-budget players.

Unfortunately, the site’s withdrawal times are some of the slowest we’ve come across, particularly when compared to fast withdrawal casinos. The site has an average of 3-7 days for the most popular payment options plus processing times of 24 hours. While deposits are free, all withdrawals come with a 1% processing fee of up to £3, so make sure you’re prepared before cashing out.

There are more than a dozen top software providers available at TheOnlineCasino, ensuring that each game you play is of the highest quality. Given the number of developers on the site, we’ve decided to highlight some of the most popular creators to demonstrate what’s on offer:

• Red Tiger – Known for creating high-quality slot games with amazing graphics, there are dozens of Red Tiger games available at TheOnlineCasino, including Apache Way, Night Roller, and Diamond Royale.
  
• Playtech – Playtech have been making world-renowned casino games since 1999, providing the industry with a selection of slots, table games, and live casino games. You can enjoy a variety of Playtech titles on the site, including Age of the Gods, Caribbean Stud Poker, and Unlimited Blackjack.
  
• Play’n Go – Specialising in creating mobile-compatible casino games, Play’n Go have created a reputation as one of the industry’s best slot developers. You can enjoy popular games such as Animal Madness, Wild Trigger, Rise of Olympus 100, and many more at TheOnlineCasino.

At Casino.com player safety is paramount, so we take steps to ensure that every casino we recommend offers a safe and fair gaming platform. Only UK casino sites that meet our high safety standards make it onto our list of recommendations. As part of our investigation, we evaluate the following factors:

• Site Security – The site uses the latest 128-bit SSL encryption technology to ensure all connections to the site are secured. It also uses firewall technology to protect your information once it reaches the site.
  
• Player Safety – There are a number of responsible gambling features available that give you complete control over your gambling. You can use deposit limits, time-outs, reality checks, and self-exclusion thanks to the site’s built-in tools. There is more information on responsible gambling and how to use these tools on the site’s dedicated “Play Responsibly” page.
  
• Casino Licensing – TheOnlineCasino is fully licensed by both the UKGC and Malta Gaming Authority. These gambling regulators are known as two of the best in the industry; any site with a license from one of these has proven that it’s running a legitimate operation.

At the time of writing, TheOnlineCasino only has a mobile app available on Android devices, meaning that iOS users will have to use the casino’s mobile website.

The Android casino app is a great way to play your favourite games while on the go; the layout is similar to that of the desktop site, making it easy to find your way around. While we did experience some long loading times, we found that the game performance was just as good as the desktop site.

We also tested the casino’s mobile website and found it to be almost identical to the app in its design, layout, and performance. This means that you’re free to choose which mobile platform is best suited for your needs.

TheOnlineCasino offers multiple support channels, including live chat and email as well as an extensive FAQ section. Both teams are available 24/7, although we found that the email team can take a few hours to respond during the busier periods.

The best way to contact the team is via the live support option, which is always available in the bottom right-hand corner. You’re initially connected to a chat bot, but it’s easy to get transferred to a real person. We were connected to an agent within 30 seconds of sending our request, and we found the team to be extremely helpful and responsive.

The site offer a fantastic game library with titles from more than a dozen top developers, as well as a range of generous online casino bonuses and promotions available to both new and existing players.

While we weren’t fans of the slow withdrawal times or the transaction fees, we were impressed by the range of payment options available. We also enjoyed the site’s dedicated mobile app, and hope to see one created for iOS devices in the near future.
