If you count the costs of going all the way to the land based casinos in Las Vegas or in other cities, then it can come up to a lot of money. This means that unless you are very rich, then you will have a lot less money to play with in the casinos. However, players in the online casinos are exempt from all of that, since they need not leave the house at all. In addition, the land based casinos like to distract their customers with all kinds of things. These can be free drinks, shows and other things. Remember that the casinos provide these things for a reason, and that is to distract you from the games, and thus lose more money. This is however, non-existent in the online casinos, where you play by yourself, at home.
