GrandMasterJack Casino Bonuses and Promotions

GrandMasterJack Casino does not joke around when it comes to bonuses and promotions. It has a massive promotions selection hosting many offers to meet your expectations. Currently, the online casino has more than 10 offers including welcome bonus, daily rewards, weekly promotions and other exclusive prizes. Let’s have a look at the most popular promotions in the casino’s catalogue.

Welcome Bonus

The welcome bonus is the most eye-catching material in GrandMasterJack Casino’s promotions selection. In total, the newbie bonus pack offers up to €300 along with 50 free spins. Besides, the operator gives the bonus rewards across the first three deposits. The minimum payment for each deposit bonus is €10. 

  • First deposit: 25 free spins that you can use on Gonzo’s Quest;
  • Second deposit: 50% bonus up to €100;
  • Third deposit: 25% bonus up to €200 along with 25 free spins on Reactoonz.

On the other hand, to withdraw the cash bonus and the winnings from free spins, you should meet an x50 wagering requirement. It is slightly higher considering industry standards. Besides, you have 30 days to wager match bonus and seven days to wager free spin winnings with a €20 maximum bet.  

As you can anticipate, it is not the biggest welcome bonus in the market. However, it provides a quick financial boost for new players. Also, we recommend you to read T&C’s before claiming the welcome bonus not to face any surprises along the way.
