The experience of playing a real human live dealer makes it similar to a real land based casino.

You know that the live dealer is real, since on the background there is usually a television running with CNN or something else which will make it easier on you to know it is real. And it is real.

The games in which you can see live dealers are usually roulette, black jack and craps.

Beating the live dealer is the same as beating the casino itself since everything is based on RNG (Random number generator), the online difference of playing against a live dealer is the ability of actually being able to see and even talk to a live human being.

The live dealer will not be able to assist you with anything related to the casino administration, you can only play with him / her.
