I play blackjack, and love getting dealt Aces, since they can count as one or eleven!
I see, my fiance deals blackjack, it seems like a difficult game
I guess if you counted cards to alter your play it would be difficult, but it's not hard for an average player.
Is it mainly about luck, do you play against the dealer or other players?
You play against the dealer, not the other people at the table.  I think it's a game of skill, though.
Oh so you try to get as close to 21 as possible, is that the goal of the game?
Exactly!  You can play with a single deck, but sometimes there are multiple decks in a shoe.
That would be hard to do it with multiple decks! How does it work if there is more than one deck
They are all shuffled together, and it actually increased the house's edge.
