Single Deck Blackjack is a variation on the basic game of blackjack in which, as the name states, one deck of cards is used. The game is played by the basic standard rules of blackjack, with several minor changes.

As in standard blackjack, Single Deck Blackjack is played against a dealer with the objective of obtaining a hand worth a higher value than that of the dealer, without busting by exceeding a total of 21. Each player is dealt two cards, face up, and the dealer takes two cards as well, one face up and one face down. Based on these cards, each player must decide to hit, stand, double down, split, surrender or take insurance (if the dealer is showing an Ace). At the end of the game, players who beat the dealer are paid and losing players forfeit their bets.

More specific rules that apply to Single Deck Blackjack are as follows:

  • 1 deck is used
  • The dealer must hit on "soft 17", a 2-card hand made up of Ace and 6
  • Players may double down only on 10 and 11
  • Players may not double down after they split pairs
  • Players may split a hand only once per hand-even if they are dealt additional doubles they may not re-split
  • The dealer checks for blackjack when they show a 10 or an Ace
  • There is no surrendering

Because Single Deck Blackjack is played with only one deck of cards, the basic strategy differs from other blackjack games. Basic strategy (i.e. when to hit, stand, split or double down) is shown in the chart below.
