Launched in September 2020, GrandMasterJack is a secure and excellent online casino where betting with Jack for the chance to win big is the order of the day. Despite being in its infancy, it has already attracted a huge following as UK players swarm the site in their thousands on a regular basis. That’s pretty impressive if you were to ask us! Run by popular software developer ProgressPlay, this casino is also a sister-site to the wonderful Irish-themed casino O’Reels. GrandMasterJack is 100% safe to use like all of the casinos we review here as it is dual-licensed by the Malta Gaming Authority and the UK Gambling Commission (License Number 039335). Sign up with GrandMasterJack to enjoy 25 Free Spins on Gonzo's Quest!

For layout, GrandMasterJack opts for a minimal design with a simple colour palette of black and white colours used throughout the site. The logo of the casino is the name in sharp-looking font with the “Jack” highlighted in red. It’s original, to say the least, and certainly sticks out when you think of all of the other generic and uninspired casino logos. When you visit GrandMasterJack, you will be taken straight to the lobby page where you will be greeted by lots of colourful rotating banners highlighting the latest promotions on the site. This is an excellent way of greeting players and shows you exactly what is going on at the casino right now in terms of special offers and events. In addition to the lobby page, there is also a top toolbar that features tabs on Promotions and Support and a bottom toolbar listing the following sections: About Us, FAQ, Deposits, Withdrawals, VIP Club, Game Payouts, Terms & Conditions, Play Responsibly, Privacy Policy, and Affiliate Program. It is a very easy casino to navigate and even better when accessed via a Mobile Phone or Tablet device.

GrandMasterJack is a hive of activity when it comes to games as it is packed with over 1,000+ superb slots and casino games to choose from. These games have been hand-picked by the GrandMasterJack team to ensure players have only the best games available to them every time they play here. To add to this, the games themselves are provided by some of the best software producers in the industry such as Play’n GO, Microgaming, NetEnt, Nolimit City, NextGen Gaming, to name just a few. Finding the right game to play might be a struggle with so much quality on offer but thankfully GrandMasterJack help out by cleverly arranging the games into categories. These include New, Featured, Slots, Casino, Live, Jackpots, Casual, All, and Favourites. Players can also sort games by provider as well as enter in text manually if you prefer to search for games that way. Featured games on the site include Rich Wilde and the Book of Dead, Starburst, and Reactoonz. The latest titles to hit online casinos are added on a weekly basis to further enhance GrandMasterJack’s already exceptional games library. A nice feature of the site is that you can play most slots for free by pressing the “Demo Play” button when hovering over a specific game. This allows you to get a feel for a game without having to place any real bets which is the best thing to do in our opinion when it comes to trying out new games here.

Naturally, GrandMasterJack also boasts a wonderful Live Casino section. This caters to players who enjoy a more old-school approach when it comes to online casinos. The Live Casino features a wide range of classic casino table games with each game beamed live from a real-life casino floor. These games are supplied by esteemed software studio Evolution Gaming. Popular Live Casino games currently available on the site include Three Card Poker, Dragon Tiger, Lightning Roulette, and Speed Baccarat.
