Winning a game of blackjack is a combination of luck and skill. Winning comes by getting the best two-card hand, which should be 21 or closest without going over (busting). The game is actually often referred to as twenty-one.
In the course of play, players may get extra cards dealt to them or discard others. Quick decisions about what to do with the cards in hand are vital to win in a blackjack round. Moreover, going into the game with a winning strategy can be most helpful. Players can take time outside competitive blackjack gambling to come up with a plan that works for them.
