The game was one of the nine launch titles available when the Atari 2600 went on sale in September 1977.
The objective is identical to the card game: to beat the dealer's card total, without going over 21, to win a bet. One to three players play the computer dealer.
The player uses the paddle controller to enter a bet of up to 25 chips from an initial pot of 200. An up card is then presented, and the player decides whether to "hit" (accept another card) or stand. The player breaks the bank by obtaining a score of 1,000 chips, or is "busted" upon losing everything.
