GrandMasterJack Casino - Video Review

GrandMasterJack Casino Review

GrandMasterJack is an online casino holding licenses, issued by two reliable EU regulators, the Promotions page is overflowing with bonus offers and these two factors alone made us believe that this casino is worth your while. Now, let’s take a closer look and check if there are any red flags you need to be careful about.

Today’s bonus


Welcome Bonus Package, Reload Bonuses, and more

Plenty of Bonuses for New and Existing Players

New players are eligible for claiming a welcome bonus package of up to €300 + free spins. The bonus is granted upon the first three deposits you make and come with a 50x wagering requirement attached. It is important to know that not all games count towards clearing the wagering requirement, but you need to clear it within a month after claiming the bonus. The max conversion is 3x the bonus amount. If you end up with a higher amount, the remaining balance will be forfeited.

If the casino retains your interest beyond the welcome bonus, you will be spoilt for choice which of the other offers to claim first. There is a different bonus for every day of the week – weekend cashback bonuses, Wednesday bonus boost, Thursday recharge, to name a few.

Note that Skrill depositors are not eligible for claiming most bonuses, but the good news is that GrandMasterJack casino supports quite a lot of alternative payment methods.

Game Selection

Slots, blackjack, roulette, baccarat, poker, virtual sports, jackpot games, lotto, and scratchcards are the game categories you will find at GrandMasterJack casino. Most games have a demo play available, so you can easily check if it is worth it to expose your bankroll to a risk and place a real money wager on a certain game. No matter if you want to feel the exciting atmosphere at the land-based casinos without leaving your couch or you are into the latest Megaways slots, the superb game selection promises you will not have a dull moment at GrandMasterJack casino.

Game Suppliers

Some of the game studios the casino works with are 1×2, 2×2, Barcrest, BTG, Blueprint, Crazy Tooth, Fantasma, Leap, Microgaming, NetEnt, NextGen, Play’n GO , Quickspin, Scientific Games, Thunderkick, Tom Horn, Triple Edge, WMS. There is an option to sort out the games by provider, but note that due to licensing restrictions, the games of some studios might not be playable from your country.

Deposits and Withdrawals

GrandMasterJack accepts payments via Visa, MasterCard, Maestro, PayPal, pay via phone, paysafe, Trustly, Interac, zimpler, ecopayZ, Neteller, Skrill, online banking, Sofort, giropay, Qiwi, WebMoney, Euteller. Some payment methods are country-specific, so you will see the full list of supported methods on your cashier page.

The minimum deposit is €20. As confirmed by a customer support representative, the minimum withdrawal is €10 and you are not required to play through your entire deposit before you are allowed to cash out. In other words, if you deposit €20 and win €200 with your very first €1 bet, you are allowed to request a withdrawal right away. In comparison, many Curacao-licensed casinos require players to turn over their deposit 1x or even 3x before allowing them to cash out.

On the downside, GrandMasterJack casino has a €2,50 withdrawal fee that applies regardless of the amount you would like to withdraw. Even though the amount is negligible, it is still a nuisance as it makes it useless to withdraw €10, for example, when you have to pay a flat withdrawal fee, and a banking fee.

GrandMasterJack Casino FAQ

GrandMasterJack is overseen by the UKGC and the MGA officials, which drastically decreases the odds of being a scam. Still, if you have any concerns about playing at recently founded casinos, you can always opt for casinos that have been in the industry for years now.

You can play a diverse range of slots, blackjack, roulette, baccarat, poker, live casino, scratchcards, virtual games, and lotto games.

Currently, there is no free cash bonus, but there are plenty of tempting offers for new and existing players.

Get in touch with customer support and make sure you haven’t abused the withdrawal terms. If you feel mistreated, you can always send a complaint to the regulator and expect the authorities in your country to take a stance on the matter. That’s one of the reasons why players should always prefer EU licensed casinos over offshore ones.

Even if you open an account and make a deposit, your winnings might be confiscated due to the use of prohibited third-party software.
