Blackjack
Atari's Blackjack uses a variation of blackjack rules that are so extremely unfavorable to the player that you would almost certainly never see them in a real casino because no one would play with them. Splitting pairs is not allowed, and more importantly, ties are won by the dealer (your bet is not returned to you if you and the dealer get the same number of cards and neither of you bust). This means a house advantage of over 10%. The player uses the paddle controller to place a bet of up to 25 chips from an initial pot of 200. Then a face-up card is revealed and the player decides whether to "hit" (take another card) or stand. The player breaks the bank if he reaches a score of 1,000 chips, or is busted if he loses everything. Due to a program error, while the player presses left or right with the paddle controller, the amount of his next bet is changed, although it is fixed by a variable that only becomes visible at the end of the game. As a result, the player must carefully re-enter the amount at the start of each game without pressing the button carelessly or risking betting an unintended amount.
