At this time, Saudi Arabia does not have any brick and mortar casinos. This is due to the fact that their Islamic laws criminalize gambling. However, the internet has provided the way around that. As a result, online gambling is very popular with many Saudi residents.
The Saudi online casinos get their licenses from the U.K., Alderney, or Isle of Man. Even with the best of software, however, there is no guarantee that interruptions won't occur. This is due to the fact that that they can't satisfy all of the jurisdiction's operational or financial requirements so they are not regulated.
