The game is usually played at an arc-shaped table with places for up to seven players on the outside and for the dealer on the inside. But if the dealer goes on to draw 21 in three or more cards, your blackjack is still a winner with its 3-2 payoff. However, if the dealer also has a two-card 21, the hand pushes, or ties, and you just get your original bet back. Blackjack pays 3-2-that is, a two-card 21 on a $5 bet will win $7.50 instead of the usual $5 even-money payoff on other winning hands.
The best total of all is a two-card 21, or a blackjack.
