Review Introduction
GrandMasterJack from ProgressPlay is a casino site offering all the things we love about online slot and casino sites. Although the name sounds a bit strange, the site is quite generic in its style; red and black is the colour scheme, and there is not a specific theme other than light touches of casino and slot imagery.
There are quite a few promotions listed on GrandMasterJack. Aside from the welcome offer, there are monthly promotion bundles, bonus codes, cashback offers, and plenty more besides. Some of the promotions run on a certain day every week, and others are across a few days, like a cashback weekend. Every month, there is a small collection of promotions which cover the month, and these are usually wrapped in quite seasonal graphics, which is nice.
GrandMasterJack: games
Which games can I play on Wish Upon a Jackpot (UK)?
Kitty Payout
A cuddly kitten features on this sickly-sweet fuzzy slot. 3 or more scattered Kitten symbols will give free spins, and the milk bowl symbol is wild. Wins including a wild will be doubled.
Spin the spellbinding reels for your chance of a magical win. Trigger up to 25 free spins when you land 3 or more scattered dragon symbols, and the wizard is wild, replacing all symbols except the dragon. The wizard also triples all wins he is part of. When you have a win, you may be given the option to keep it or gamble it in a game of chance.
