bj - the game of black jack
Bj is a serious attempt at simulating the dealer in the game of black jack (or twenty-one)
as might be found in Reno. The following rules apply:
The bet is $2 every hand.
A player `natural' (black jack) pays $3. A dealer natural loses $2. Both dealer and
player naturals is a `push' (no money exchange).
If the dealer has an ace up, the player is allowed to make an `insurance' bet against
the chance of a dealer natural. If this bet is not taken, play resumes as normal.
If the bet is taken, it is a side bet where the player wins $2 if the dealer has a
natural and loses $1 if the dealer does not.
If the player is dealt two cards of the same value, he is allowed to `double'. He is
allowed to play two hands, each with one of these cards. (The bet is doubled also;
$2 on each hand.)
If a dealt hand has a total of ten or eleven, the player may `double down'. He may
double the bet ($2 to $4) and receive exactly one more card on that hand.
Under normal play, the player may `hit' (draw a card) as long as his total is not
over twenty-one. If the player `busts' (goes over twenty-one), the dealer wins the
When the player `stands' (decides not to hit), the dealer hits until he attains a
total of seventeen or more. If the dealer busts, the player wins the bet.
If both player and dealer stand, the one with the largest total wins. A tie is a
The machine deals and keeps score. The following questions will be asked at appropriate
times. Each question is answered by y followed by a new line for `yes', or just new line
? (means, `do you want a hit?')
Every time the deck is shuffled, the dealer so states and the `action' (total bet) and
`standing' (total won or lost) is printed. To exit, hit the interrupt key (DEL) and the
action and standing will be printed.
All times are GMT -4. The time now is 01:34 PM.
