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.

The games on GrandMasterJack are all either slots or casino, with a couple of exceptions like virtual sport and scratch. There are listings for new and featured slots, so you can see which games are fresh and popular, as well as a search bar to find games by title. There are lots of casino games available, including blackjack, poker, and roulette. In addition, live casino tables are on offer, where a dealer will host the game for you live on camera.

GrandMasterJack is compatible with mobile, PC, and tablet devices. As there is not an app, the site can be accessed through your internet browser by going to the website. This means that you can play at home or out and about with no trouble at all.
