Game selection
CasinoGB has a vast experience in games. They have worked with a huge number of game developers. The game developers range from the well-known to the barely known, but all seem to be pretty good at what they do. They have put together a selection of games that is pretty solid across the board—at least as solid as any other site I have seen.
Even so, the overall total of games isn't all that impressive. You won't find the total creeping up toward 500. You'll probably see a little over 400. That's more than you could ever play, really, in one lifetime, but considering that most sites have at least double that, CasinoGB stands out in a slightly negative way.
The unfortunate thing is navigation. It is a bit clumsy, and one does not immediately jump with lightning speed between the various departments and suppliers. It is interesting, though, to note that the navigation works quite a bit better on mobile platforms. Since the site is otherwise completely mobile-first, it probably performs better on mobile and tablet.
Jackpot games
Sadly, at CasinoGB, there is some skimping on the jackpot games. The main games in this category are King Cashalot and Tunzamunni, which are honestly just really old titles from Microgaming. You can also find Divine Fortune and Dolphin Gold, which may add a bit more weight to the jackpot section.
Online casino
The vast majority of online casinos opt for Evolution Gaming as a live dealer casino provider. CasinoGB has not done this. Instead, they have a contract with NetEnt and Extreme Live Gaming. Unfortunately, with these two providers, the live dealer game selection is quite meager. At present, you can only play blackjack and roulette in the form of a live dealer at CasinoGB. Let's hope that maybe in the near future, the selection of live dealer games will be a bit more robust.
