I have visited physical casino before but I have not tried my hands on it, since you said it's fun, I will have to try it one of these weekends. There is a snooker board in one of the casino hall on my my town, I have been going there for snooker but have not tried the slot machine, reason being that I don't really have passion for physical casino as I like doing my things confidentially. The background sound is actually enticing, which is one of the reason I will try a few hands.
On the basis of transparency, I think both are similar because if the physical can be rigged, the only can as well be rigged. At some point I was thinking that it is the physical casino that is easier to rig but a second thought just showed me that both can be rigged.
