The Rules of Canfield

In Canfield, tableau cards may be built on each other downward in alternate 
colors. An entire pile must be moved as a unit in building. Top cards of the piles are available to be able to be played on foundations, but never into empty spaces.

Spaces must be filled from the stock. The top card of the stock also is 
available to be played on foundations or built on tableau piles. After the 
stock is exhausted, tableau spaces may be filled from the talon and the 
player may keep them open until he wishes to use them.

Cards are dealt from the hand to the talon by threes and this repeats until 
there are no more cards in the hand or the player quits. To have cards dealt 
onto the talon the player types 'd' for his move. Foundation base cards are 
also automatically moved to the foundation when they become available.

The rules for betting are somewhat less strict than those used in the 
official version of the game. The initial deal costs $13. You may quit at 
this point or inspect the game.  Inspection costs $13 and allows you to make 
as many moves as possible without moving any cards from your hand to the 
talon.  (The initial deal places three cards on the talon; if all these cards 
are used, three more are made available.) Finally, if the game seems 
interesting, you must pay the final installment of $26.  At this point you 
are credited at the rate of $5 for each card on the foundation; as the game 
progresses you are credited with $5 for each card that is moved to the 
foundation.  Each run through the hand after the first costs $5.

In xpat2, you have to pay the full amount of $52 at the beginning. This makes 
a maximum score of $208, if you use only one turn (i.e. no flips), which 
should be quite rare.
