Blacjack was no longer promoted by Atari following the release of Whitehead's Casino in 1979, but still continued to sell in small amounts as late as 1989.

Retrospective reviews were generally dismissive, with Brett Weiss and AllGame noting low quality sound and graphics while Kevin Bunch in Atari Archive: Vol.1 1977-1978 found that the release of Casino made Blackjack a relatively superfluous game for the Atari 2600.

A player's bet is either added or subtracted from their total score depending if they won or lost the round.

[6] Whitehead began work on Blackjack following his adaptation of the arcade game Starship 1 (1977) with Star Ship (1977) for the Atari 2600.

[10] Other than Combat which was included with the release of the Atari 2600, Blackjack was one of the initial eight launch titles that were shipped in September 1977.

[13] Guidice was originally hired by Atari to for his architectural design skills to create the entrance for their building.

This led to contract work with Atari for illustrations he would make based on descriptions of the games.

[14] Guidice said for Blackjack he was given creative freedom from the Atari art directors to come up with image ideas and decided to illustrate playing cards and happy people in a casino setting.

"[2] Brett Weiss in his book Classic Home Video Games 1972-1984 (2007) complimented the control via the paddle allowed for nice rapid play, while finding that the graphics and sound to be "as primitive as possible", noting the lack of suits on the cards and the lack of certain gameplay elements of Blackjack such as the ability to double down or split pairs.

[1] Kevin Bunch in Atari Archive: Vol.1 1977-1978 found that the release of Casino (1979) made Blackjack a relatively superfluous release in the Atari 2600 library, while saying it "was not a bad rendition of the card game" noting the ease of use in the controller, and highlighted small touches like the sound effect of the dealer cutting the cards if the player gets through an entire deck.

[10] Following the release of Casino, BlackJack was no longer highlighted in promotional material from Atari and was discontinued by the January 1982 Consumers Electronic Show.

The game stayed on the market with some remaining small sales figures still appearing as late as 1989.
