Intro

GrandMasterJack may not have the instant brand recognition enjoyed by other, more prominent casino sites in the UK, but it’s certainly worth checking out. Brand new to the scene, having been founded in 2020, GrandMasterJack “was established to provide quality entertainment to people who enjoy gambling”, which pretty much says it all. Curious to know what this new gambling site in the UK has to offer? Read on for our detailed assessment of the site’s offering, features, bonuses, and more.

WAGERING REQUIREMENTS

Whenever sizing up a welcome bonus, it’s important to consider the wagering requirements. At GrandMasterJack, you’ll have to bet the bonus amount, or any winnings from free spins, 50 times over before you can cash out the funds. This is fairly high compared to many other UK casino sites, and will likely mean that most players will be unable to withdraw any bonus-related winnings before the bonus expires. That being said, the funds can be viewed as a means to get acquainted with the site’s games and features without having to wager too much of your own cash.

GrandMasterJack has a rather unusual welcome bonus offer. Matched deposits are available, as you might expect, but not from the very start. When you make your first deposit, you can only unlock free spins (25 in total) at first. It’s only when you deposit a second time that you can have a 50% bonus up to £100. Then, with your third deposit, there’s a 25% bonus up to £200, along with another bundle of 25 free spins. While this may seem a bit odd and even off-putting at first glance, if you’re planning on sticking around beyond your first deposit then there’s not really much difference between this package and those that provide matched bonuses right off the bat.

Software

No matter how slick and appealing a casino site looks, what really matters is the quality of its games archive, and that comes down to which software developers have delivered the games in question. GrandMasterJack has done well here, hosting slots, table games, and live casino games from industry-leading tech maestros like Play’n Go, NetEnt, Yggdrasil, and Evolution. This means you can experience cutting-edge games with innovative features, top visuals, and plenty of fun to be had.

Slots

9/10

As you might expect – given how popular they are at all UK online casinos – you’ll find slots galore at GrandMasterJack. Golden oldies like Rainbow Riches jostle alongside immersive, adventurous slots like Rich Wilde and the Book of Dead, and Finn and the Swirly Spin. If you have a thing for slots that tie-in with films and TV shows, you’ll be very happy with the offerings here, with slots like Who Wants to be a Millionaire Megaways and Jurassic World ready for you to take a spin on their reels.

Being able to interact with live dealers in a convincingly casino-like environment is one of the most appealing aspects of online gaming. GrandMasterJack has a respectable number of live casino games on offer. It’s not the biggest or most eclectic range we’ve ever seen, but it does cover the main bases, letting you play classic games like baccarat, blackjack, and roulette. GrandMasterJack has room for improvement when it comes to game show-esque experiences, which are notably absent at the time of writing.

Blackjack

9/10

It’s fair to say that most people who like card games love blackjack. It’s a game that works particularly well in the live dealer format, as racing a real human dealer to 21 brings the kind of excitement that you’d be hard-pressed to match with a random number generator-based game. GrandMasterJack has several blackjack games in its live casino section, including fun variations like Evolution’s Dragon Tiger game. That said, you can also enjoy a spot of virtual blackjack in the regular online casino sense, with games like European Blackjack and Vegas Strip Blackjack ready to play.

Roulette

7/10

The whirr of the roulette wheel is one of the hallmarks of a great night out in a casino. You can have the next best thing when you play live casino roulette at GrandMasterJack, where variations include French Roulette and Lightning Roulette. Having a real croupier spinning a physical wheel will surely ramp up the exhilaration and make you feel like you’ve been teleported to a proper casino. If you’re after more low-key amusement, you can of course opt to place bets on virtual roulette. Games in this section include World Cup Roulette and 3D European Roulette.

Poker

Poker is one of those games which is often underrepresented at regular online casinos, unless they happen to have a proper, poker-focused sister site. GrandMasterJack actually has more virtual poker games than many comparable sites we’ve seen, with a large variety of titles including Triple Double Bonus Poker, Joker Poker, and Casino Stud Poker. The live dealer poker offering is small, however, with just one title available. On the plus side, the game in question is Three Card Poker by live dealer specialists Evolution, so you know you’re going to be in very capable hands.

9/10

There’s one simple rule of thumb when it comes to banking options at an online casino: the more, the better. At GrandMasterJack you have a wealth of options at your disposal, as members can make transactions using bank cards, Skrill, Neteller, Bitcoin, ecoPayz, PaysafeCard, and MuchBetter. How long you have to wait for withdrawals to process depends on which method you go for. If time is of the essence, you should opt for Skrill or Neteller, as GrandMasterJack will aim to process and transfer the funds to you in 2 days. Other methods may take up to a week or longer.

Design & Usability

While GrandMasterJack won’t win any prizes for originality in terms of its look and feel, that doesn’t really bother us because it is a fantastically easy site to use. The games archive is a pleasure to browse as the titles and logos are presented in a big, easy to read way. The various sections of the site are also clearly signposted with large tabs, so skipping from slots to table games to the live casino can be done in a flash. In summary, GrandMasterJack gets top marks for usability, even if you’re totally new to online casino gaming.

Mobile Experience

7/10

While some online casino sites in the UK have their very own specially-designed native apps which you can download to your device, GrandMasterJack doesn’t currently have such an app available. While it would be great if it did, this is certainly not out of the ordinary for such a new site. The good thing is that the website is optimised for use on your smartphone or tablet, so you can easily play on the go simply by accessing the URL and signing in as normal.

Loyalty and VIP Rewards

GrandMasterJack may be new to the scene, but it’s already got a VIP scheme in place to make members feel right at home. You’ll earn a VIP Point with every £16 wagered on the site, and collecting these points will allow you to ascend the rankings, from Bronze through to Diamond. Along the way, you’ll be gifted extra benefits and have the ability to convert points into cash. The highest levels also unlock personalised services to give you that authentic VIP experience.
