Its rules are quite simple; basically you want to beat the dealers hand by reaching 21 points (blackjack) or to get as near as possible, without exceeding it, otherwise you automatically loose.
Blackjack is normally played in a multiplayer table and wagers are placed before each hand.
Cards values are the following: face cards (jack, queen and king) count 10 points, numbered cards add up their natural value and aces can be both one or eleven points according to the players interest. Each player is dealt an initial hand of two cards.
On every turn, players must choose whether “to stand”, that is to stay put with the cards they have got or “to hit”, which means to receive an extra card to add more points, this way risking the chance of exceeding 21 or “breaking”.
If “the house breaks”, meaning that the dealer has more than a 21, all remaining players win.
On the other hand, if the house “stands” at a certain number, all hands with a lower score lose.
In case of a tie, wagers are returned. If your first two cards have the same value, you can split them into two hands, by placing a second bet equal to the first.
Then the dealer separates the two cards and draws a further card on each. The player then plays the two separate hands in each turn.
While the basics of the game are always the same, you will find many variations of Blackjack.
In any case you will always depend on your luck and your skills as well, so it is important to practice a bit and get to know the game before you place your wagers.
