Firstly, blackjack is a card game and like all card games, blackjack is both played and won with a combination of skill and luck. Playing online is really no different from how the game would be traditionally played. The rules and odds are the same, online, however, you have far greater choice in the variants of blackjack that you can play. Playing is simple, you are dealt two cards and so to is the dealer, you must form a hand that reaches up to 21 but not over. If your hand beats the dealers total, you win.
