The truth is that what you think you are seeing right in front of you may not be as you see it. So long as it's a kind of system operating it, it can be rigged, whether it is online or offline. However, the online gambling system can be more rigged than the physical ones, and some of the ones you have access to in physical casinos are now purely electronic. This means that they can also be easily rigged regardless of where you are accessing them. It is the question of how you are accessing them.
