Apocryphal background
The best computerised card game I have played is SeaHaven Towers, by Art
Cabral .  It unfortunately cannot be played on an SE/30 so I 'ported it' to my
Card Shell system.

The Aim
The aim is to simply build up the four foundations from Aces to Kings each in
strict suit order.

The Deck
A deck of 52 cards is used, comprising of a normal 52 card deck. 

The Layout and Deal
•Ten columns of five cards are dealt face up and the remaining two are placed
face up in the two fo the four special spaces above. 
•Aces are layed of immediately, before the game starts.
•All this is achieved using the New Game item (⌘N) on the File menu.

Moves
•Only one card may be moved at a time.
•Any card may be played into a vacant special space above the columns.
•By combining the above rules, the program will allow the player to move 
one card plus one for each special vacancy at a time, as long as the pile
being moved is a descending sequence according to the matching rules in force.

Special moves
•Each move made is recorded by the computer.  Using the Moves menu the player
can step back through previous steps and forward again to the most recent move.
This means that an erroneous move can be undone.  In fact the entire game can be 
replayed.  Use of the Forward (⌘F) and Backward
(⌘B) is permitted under the rules,  it is in fact encouraged.

Sequences
•Sequences in columns may be built up according to the rule currently in force.  The
rules may be selected using the Moves menu with the Sequences… item. 
•The standard rule says that sequences are built in descending rank sequences of 
the same suit.  This may be changed to be simple descending rank, regardless
of suit, or descending sequence in alternating.
•In general the simple rank rule is to easy and the strict suit rule is standard.

Endgame
•The game is lost if no further foundation layoffs are possible.  Scoring is done
after choosing New Game (⌘N)from the File menu, before the new game is
dealt.

Scoring
The scoring is a points system that depends on the rules in use for a given game
according to the following table:

               Rule                                       Win 

Loss
               Match any suit                         0pt         0pt
               Match alternating colour          1pt        -4pt

 Match same suit only               4pt        -1pt

The match anuy suit rule is really unsuitable for this game.
The scores are recorded along with some other statistics such as winning/losing
streaks and game move counts.  Overall points and winning percentages as well
as a breakdown by rule type is given at the end of each game and at any other time
using Scores… from the Special menu.

Strategies

Cool features of the Card Shell games
•Automatic saving means that you can quit at any time and when you restart
the game is restored as it was left off.
•All the games from the card shell can simultaneously share the same 'Cards' file.
This contains the sounds and cards pictures.  This saves duplicating ~400k of
common data for each new game.  The games themselves come out about 50k each.
•The very first time a Card Shell game is started, it looks for the Cards file in the
same folder as the game.  If it cannot find it the user is prompted to find it.  Once 
found its location is recorded along with identification and search info. so that
the 'Cards' file can subsequently be moved anywhere else on the disk and still be
found.
•The card graphics have be optimised to work equally well on B&W monitor settings
as well as 4,16,256,thousands and millions of colours.  The layout will fit (just) on
the small 9" monitor of an SE/30, and on larger screens the window can be moved 
anywhere on a multiple monitor set-up.

Artwork
•The court cards are quite symbolic.  I have included motifs of the original
card suits: Staffs, Cups, Swords and Coins on their modern counterparts:Spades
Hearts, Diamonds and Clubs.  This means that I have moved the characteristic
'oops I've just stuck a sword though my head!' from the King of Hearts to the
King of Diamonds, and given the King of Hearts a nice drink (cup) instead.
•The  other common convention in the court cards is the identities of the 
one eyed cards: Jack Hearts, Jack Diamonds and King of Diamonds.  This will 
permit the playing of some obscure Poker variants that actually depend on this.
•The cards are in the form of colour icons in the 'Cards' file.  The cicns 
also contain modified B&W versions that will look better in mono than just letting 
quickdraw do it's stuff.
