Here it is perhaps worth noting that visiting many casinos still requires quite a lot of time.  But if a novice player still sets himself the goal of studying different options and different games in the casino, then there is no escape from this expenditure of a lot of time.  It will take quite some time to figure it out.  This should be done only when a person himself understands that he is interested in gambling and this interest does not go away after he has tried playing in two or three different casinos.  If your interest in gambling is stable, then the process of exploring different options will be easy and without any extra effort in forcing yourself to do it.  It seems to me that not all people are capable of this, but only a small part of them. 
But these are the ones who go on to become really good players.  And over time and as they develop, they also become experienced players.
