The highest hand in blackjack is an ace and any 10-point card and is called a blackjack. A winning blackjack pays 2:1. If both player and dealer have a blackjack the bet is a push. Aside from a blackjack, a winning hand pays even money. The player wins if his hand has more points than the dealer, without going over 21. Thus a 21-point hand is the highest and is why the game is sometimes called 21. If either the player or dealer go over 21 it is called a break or bust and automatically loses. If the player and dealer tie, the bet is a push.
