The baccarat section presents three opportunities – Baccarat, Dragon Tiger, and Dragon Bonus Baccarat. There are only three scratch card titles and two lotto games.

Payment Methods: Safe Deposits and Withdrawals from the UK

It is advisable to check the payment options before signing up with an online gaming platform. That way, you will see if the operator offers what you need. GrandMasterJack has legit and secure payment methods, including bank cards, e-wallets and crypto payment processors like BitBay Pay. The complete list is shown below. All deposits are instant, and they have a minimum amount range from £10 to £20, depending on your chosen banking method. Those of you going for Pay by Mobile transfers will incur a hefty 15% processing fee. You could try these alternative pay with mobile phone online casinos if those charges are a little steep for your liking. Each system works with a different number of currencies.

There is a minimum three-day pending period for cash outs for all payment methods. That is pretty standard, but for some might be a tad slow. The whole process will take about 3 to 7 days for your real money funds to reach your bank account. That is, of course, when using bank cards and some e-wallets. In case you go for bank transfers, you will wait around 4-10 working days. Remember that regardless of the method and how big or small your winnings are, you’ll also sustain a substantial £2.50 fee on each withdrawal.
