Bonuses & Promo

Bonuses & Promotions

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.

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.

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.

Cashier

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.

Mobile Experience

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.
