- H89 YAHTZEE: a game of dice.
-
- USAGE: A>yahtzee [options] name1 name2 ...
-
- initiates a game between the k players named. If any of the
- names are prefixed with an equals sign ('='), the computer will
- make the moves for that player. Thus,
-
- yahtzee me =reagan =king
-
- will initiate a game between one human and two artificial
- players, a relatively civilized outlet for vengence. Options
- may include:
-
- -d# Delay time #. Specifies simulated thinking time
- for artificial players (and allows you to watch
- their playing); default is 10000. Try -d1 for
- quick action.
-
- -ha# Set parameters for automatic playing heuristic;
- -hb# effect varies with program version, and in any
- ... case is difficult to describe.
-
- -r# Set initial random number seed; identical seeds
- yield identical games. Allows duplicate games,
- in the spirit of duplicate bridge.
-
- IDEA: Each of n players take turns in rotation. On each turn, a player
- rolls 5 dice (and may reroll arbitrary subsets a maximum of two
- times). He then enters the resulting score in some row of his
- score card, counting points in various ways depending on the
- row chosen. The game ends when each player's score card is
- full, the player with the highest score being the winner.
-
-
- SCORING: The rows of the score card are as follows:
-
- ACES Count only 1's in roll.
- TWOS Count only 2's in roll.
- THREES thru SIXES You get the idea.
-
- ----------------- "The line" - see below. ------------------
-
- 3 of a kind If roll contains three of a kind, count
- the sum of all 5 dice; else zero.
- 4 of a kind Sum of dice, if roll has 4 of a kind.
- YAHTZEE means 5 of a kind. Count 50, if roll
- contains 5 of a kind.
- Full House count 25 if roll contains a pair AND 3
- of a kind.
- 4 straight counts 30 iff roll contains 4 consecutive.
- 5 straight counts 40 iff roll contains 5 consecutive.
- CHANCE Count sum of all 5 dice.
-
- In addition, a bonus of 35 is added to a player's score iff the
- sum of points scored above the line is greater than 62. Note
- that this sum is just met by 3 dice scored in each denomination.
-
-
- PLAY: On each player's turn, he interacts by pressing the special
- function and keypad keys. The button immediately under each
- die selects that die for re-roll; the ROLL button (which may be
- pressed at most twice per turn) causes selected dice to assume
- their new values. OOPS restores erroneously selected dice.
- DONE (or equivalently, RETURN) ends the turn, posting the roll
- in the currently selected row of the score card.
-
- The currently selected row is distinguished by a WHITE (reverse
- video) field in the player's score column. Alternative rows
- may be selected by pressing UP and DOWN arrows on the keypad,
- or pressing the SPACE bar. Only legitimate (previously unused)
- rows may be selected. Selection of an inappropriate row (eg,
- four of a kind when the dice contain no such combination) is
- a valid move, but sacrifices that row (with a zero score) for
- the game; since each turn must be entered in SOME row, such
- scratches are necessary at times.
-
- N.B... The WHITE score (in the selected row) is added in as if
- it were selected. Thus a player may check the impact of
- posting in various places by banging on the space bar.
-
- BUGS:
- 1) Although this game has a cult following, the author rates
- it marginally more interesting than computerized blackjack
- -- perhaps in a class with backgammon.
-
- 2) Although kids first enjoy beating, say, Napolean in straight
- sets, they will soon discover that a command like
-
- yahtzee =carter =reagan
-
- allows them to sit around watching the H89 like television.
- Fortunately, they get bored by this more quickly than by TV --
- maybe I should add commercials to the program to heighten its
- amusement value.
-
- 3) The automatic-play heuristics are both ad-hoc and poor.
