Yes, you can interact with the dealers just like in a casino. Most live dealer games have a chat feature so you can talk to the dealer. Some have a chat box where you can write your request. Depending on the casino, some dealers will be talkative, while others will be calmer. This is not up to you – it’s what the casino has instructed them to do.
And, no, the dealers can’t see you. You can see them and interact with them, but it’s not a ‘two-way mirror’. Some live dealer games have some social features such as a chat where you can talk to other players. The social element adds even more excitement to the game and brings it a step closer to land-based casinos.
