The goal of blackjack is to acquire as high of a value as likely
without going over 21. If you go over 21, you bust and the
dealer wins the hand. You get hold of the value of your hand
by totaling together the cards that are face up in front of
you, remembering though that the ace is worth either 1 or
11. So if you had two 10's and an ace, you would have a hand
worth 21, because apparently you would want the ace to count
as 1.
Blackjack is a solo game. Even though there might be 8 players
at a table, there can be no teamwork between the players.
It is strictly a one on one game between the player and the
dealer. If you beat the value of the dealer's hand without
busting, then you win the hand, no matter how well any of
the other player's hands did. If the dealer busts and you
don't bust, then you win the hand as well.
