Wagering requirements

While the significant T&Cs are pretty standard, the wagering regiments are, unfortunately, pretty steep at this casino. You’ll have to wager the bonus or any free spins winnings 50x before you can convert your bonus money into real cash.

GrandMaster Jack Login – How to get started

Grandmaster Jack casino registration screenshot

Joining GrandMaster Jack could not be easier. To get started, click the ‘Join Now’ button and follow the on-screen instructions. The standard online registration form will then walk you through the steps required to create a new player account. All it will ask of you is your full name, date of birth, residential address and a valid mobile number for verification.

Promotions & Offers

GrandMaster Jack looks like a generous chap when it comes to promotions. Here you’ll never be short of seasonal offers, cashback weekends, mid-week showdowns and weekend treats. There’s always something going on for those returning to the site for some fun times.

Because of the nature of the seasonal promotions, such offers will expire as the new season approaches. So it’s best to check back in with the casino regularly or opt-in to their marketing emails to see what’s new coming up.

Casino Games & Slots

You’ll find a massive selection of slots, jackpots and v-sport games at GrandMaster Jack. The lobby here is conveniently organised into sections allowing you to smoothly navigate their extensive library of 1,600+ casino games.

Though the jackpots catalogue doesn’t house any of the famous progressive jackpot slots like Mega Moolah, it still offers a satisfying selection of games with jackpots.

Under the ‘Featured’ section, you can check what’s been selected for you already by the casino. You’ll see the grand titles such as Book of Dead and Thunderstruck 2 as well as more recent releases.

Navigate to the casino tab, and you’ll discover a decent selection of blackjack, roulette, video poker, and
baccarat variants.

Game Providers

The line up of the game providers is pretty impressive at the GrandMaster Jack Casino site. Counting 50+ creative studios, you ought to find your favourites on the list. Here’s just a handful of the best-known developers to give you an example:

Payment & Processing time

You can deposit and withdraw at GrandMaster Jack using a wide variety of depositing methods. The full list includes the most common debit cards, e-wallets, pay by phone, and good old bank transfers.

All deposits are instant with the minimum deposit limit ranging from £10 – £20 depending on your chosen banking method. If you decide to deposit using Pay via Phone, you’ll incur a hefty 15% processing fee, so just be aware of that.

Withdrawals here are pretty standard if not a tad slow because of a three-day pending period for all payment methods. It will take roughly 3-7 days for your real money funds to reach your bank account when using bank cards and some e-wallet providers, and around 4-10 working days for a bank transfer. The lowest withdrawal amount here is £10.

You’ll also sustain another bulky £2.50 fee on each withdrawal, regardless of how big or small your winnings are. And remember that Skrill is excluded from the above list of available banking options, so take your pick from the alternatives mentioned.

Customer Service

It’s great to know that the live chat support option here is open 24/7 so don’t hesitate to contact the support team if you have any casino-related queries. You can also contact GrandMaster Jack’s team by submitting an online enquiry via the form. But before you do, take a look at their extensive FAQs section that covers anything from registration to technical issues that you might experience.

Special Features

GrandMaster Jack Casino is licensed and regulated by the Gambling Commission, making it a safe and secure gambling platform for any UK player. Below we’ve listed some other special features that you’ll find beneficial.

GrandMaster Jack on mobile

You can easily access the site by firing it up via your smartphone’s native browser. It loads quickly on both Android and iOS devices and is optimised to perform well both visually and technically via any trusted mobile casino.

GrandMaster Jack Live Casino

Under the ‘Live’ tab, you’ll find plenty of live casino games powered by NetEnt and Evolution that are hosted by friendly and professional live dealers. Choose from live roulette, live blackjack, and live baccarat, live poker or the Dream Catcher fortune wheel. Sadly, we didn’t detect any live casino bonuses available for live casino fans, nor do their welcome bonuses contribute towards any of these options.

GrandMaster Jack VIP

Should you choose to revisit GrandMaster Jack, you’ll have the opportunity to join their 5-tier VIP club. Every time you play for real money here, you’ll earn points and take a step closer to getting rewarded with some extra benefits.

As a new player, you’ll start at the Bronze VIP tier and, if your budget allows, work your way up to the highest Diamond VIP tier. The higher the status, the better the perks, including discounts, extra bonuses, personalised gifts, customised promotions and more. Please gamble responsibly.
