UK Welcome Offer

GrandMasterJack welcomes all new UK players with a welcome package consisting of 3 different bonuses. You’ll be met with 2 deposit bonuses and a bonus granting you free spins on top of your deposit.

  • The first bonus is 25 Free Spins for Gonzo’s Quest.
  • The second bonus is a 50% deposit bonus up to €100
  • The third bonus is a 25% deposit bonus up to €200 + 25 Free Spins on Reactoonz.

All the bonuses have a wager requirement of 50x, meaning you have to wager your bonus 50 times before being able to make a withdrawal. This applies both to the bonus received from a deposit bonus, but also for the winnings achieved from free spins. Your max bet is €5 when wagering, the minimum deposit is €10, and you have a total of 30 days to complete a wager.

No-Deposit Bonus and Free Spins

No players are granted no-deposit free spins or a no-deposit bonus when signing up on GrandMasterJack. Though, all new players are able to take advantage of the welcome package offered, and through that receive a total of 50 free as non UK residents and 75 Free Spins as UK residents!

Wagering requirements and percentages.

When accepting a bonus on GrandMasterJack, you also accept the Terms and Conditions regarding the bonus. All bonuses and free spins winnings have a wager requirement of 50x, meaning you have to wager the bonus money 50 times before being able to request a withdrawal. Bonuses are valid for 30 days after activation and free spins are valid for 7 days after being added to your account.

Wagering on GrandMasterJack is only allowed through real money play, this means you won’t be able to wager anything through demo play. Besides only allowing wagering to be done through real money play, you have to check the percentage each game wager on the casino. This is due to not all games wagering the same percentage of the bet you place, and has made us put together the list below, where you can see the wagering percentages on each game.

GameWager percentage
Slot Machines100%*
Poker Table Games10%
Jackpot Games10%
Video Poker5%

*A few slots aren’t eligible for wagering. Please read the Terms and Conditions to see if your favourite slot is on the list of games that do not contribute to your wager at all.

Besides having a wager requirement, you also have a max bet of €5 or €0.5 per line while having an active bonus. This means you’re not allowed to place a bet higher than €5 in a single round. If you accidently do go over the maxbet, we recommend trying to contact support immediately to possibly prevent your bonus from being terminated.
