SYNOPSIS

DESCRIPTION

craps is a form of the game of craps that is played in Las Vegas. The program simulates the roller, while the user (the player) places bets. The player may choose, at any time, to bet with the roller or with the House. A bet of a negative amount is taken as a bet with the House, any other bet is a bet with the roller.

The player starts off with a ``bankroll'' of $2,000.

The program prompts with:

    bet?

The bet can be all or part of the player's bankroll. Any bet over the total bankroll is rejected and the program prompts with bet? until a proper bet is made.

Once the bet is accepted, the roller throws the dice. The following rules apply (the player wins or loses depending on whether the bet is placed with the roller or with the House; the odds are even). The first roll is the roll immediately following a bet:

    1. On the first roll:

    7 or 11
        wins for the roller;
    2, 3, or 12
        wins for the House;
    any other number
        is the point, roll again (Rule 2 applies).

    2. On subsequent rolls:
    point
        roller wins;
    7   House wins;
    any other number
        roll again.

If a player loses the entire bankroll, the House will offer to lend the player an additional $2,000. The program will prompt:

    marker?

A yes (or y) consummates the loan. Any other reply terminates the game.

If a player owes the House money, the House reminds the player, before a bet is placed, how many markers are outstanding.

If, at any time, the bankroll of a player who has outstanding markers exceeds $2,000, the House asks:

    Repay marker?

A reply of yes (or y) indicates the player's willingness to repay the loan. If only 1 marker is outstanding, it is immediately repaid. However, if more than 1 marker are outstanding, the House asks:

    How many?

markers the player would like to repay. If an invalid number is entered (or just a carriage return), an appropriate message is printed and the program will prompt with How many? until a valid number is entered.

If a player accumulates 10 markers (a total of $20,000 borrowed from the House), the program informs the player of the situation and exits.

Should the bankroll of a player who has outstanding markers exceed $50,000, the total amount of money borrowed will be automatically repaid to the House.

Any player who accumulates $100,000 or more breaks the bank. The program then prompts:

    New game?

to give the House a chance to win back its money.

Any reply other than yes is considered to be a no (except in the case of bet? or How many?). To exit, send an interrupt (break), DELETE character or CTRL-D The program will indicate whether the player won, lost, or broke even.

MISCELLANEOUS
The random number generator for the die numbers uses the seconds from the time of day. Depending on system usage, these numbers, at times, may seem strange but occurrences of this type in a real dice situation are not uncommon.
