Casino (Atari 2600, 1979)

Don't blow your cash in Vegas! Blow it on Atari's Casino, with three games of luck and skill that will test your mettle as an ace card player. You and three of your friends can challenge the computer in games of blackjack, stud poker and poker solitaire. Break the bank, or go bust -- it's up to you.

Casino is the successor to Atari's Blackjack. The look and feel of the two games is almost identical, with the same green background and the same method of paddle control for selecting your choices. 

Games 1 and 2 are devoted to blackjack. Game 1 is for one or two players and allows you to split a hand. Game 2 is for one to four players and does not allow splitting. Other than that, gameplay is identical to Atari's Blackjack. 

Game 3 is 5-card stud poker for one to four players. Cards are played face up, and players bet their hand only against the computer. Players may bet after each card is dealt, with the option to fold at any time. Set the left difficulty switch to the 'A' position and the computer's first card will be dealt face down. The right difficulty switch will affect the players' first card similarly.

Game 4 is a one-player game called poker solitaire. The player is dealt cards which they arrange in a 5x5 grid. Hands are added up horizontally, vertically and diagonally. Better hands are worth more points.
