Document 12: Blackjack: Once all the players have completed their hands, it is the dealer's turn. The dealer hand will not be completed if all players have either busted or received Blackjacks. The dealer then reveals the hidden card and must hit until the cards total 17 or more points.

Players win by not busting and having a total higher than the dealer, or not busting and having the dealer bust, or getting a blackjack without the dealer getting a blackjack. If the player and dealer have the same total (not counting blackjacks), this is called a`` push'', and the player typically does not win or lose money on that hand. Otherwise, the dealer wins.
