In 51Canfield, tableau cards may be built on each other downward 52in alternate colors. An entire pile must be moved as a unit 53in building. Top cards of the piles are available 54to be played on foundations, but never into empty spaces. 55.Pp 56Spaces must be filled from the stock. The top card of 57the stock also is available to be played on foundations or 58built on tableau piles. After the stock is exhausted, 59tableau spaces may be filled from the talon and the player may 60keep them open until he wishes to use them. 61.Pp 62Cards are dealt from the hand to the talon by threes 63and this repeats until there are no more cards in the hand 64or the player quits. To have cards dealt onto the talon the 65player types 66.Sq Ic ht 67for his move. Foundation base cards are 68also automatically moved to the foundation when they become 69available. 70.Pp 71The command 72.Sq Ic c 73causes 74.Nm 75to maintain card counting statistics 76on the bottom of the screen. 77When properly used this can greatly increase one's chances of 78winning. 79.Pp 80The rules for betting are somewhat less strict than 81those used in the official version of the game. 82The initial deal costs $13. 83You may quit at this point or inspect the game. 84Inspection costs $13 and allows you to make as many 85moves as possible without moving any cards from your hand 86to the talon. 87(The initial deal places three cards on the talon; 88if all these cards are used, 89three more are made available.) 90Finally, if the game seems interesting, 91you must pay the final installment of $26. 92At this point you are 93credited at the rate of $5 for each card on the foundation; 94as the game progresses you are credited with $5 for each 95card that is moved to the foundation. 96Each run through the hand after the first costs $5. 97The card counting feature 98costs $1 for each unknown card that is identified. 99If the information is toggled on, 100you are only charged for cards 101that became visible since it was last turned on. 102Thus the maximum cost of information is $34. 103Playing time is charged at a rate of $1 per minute. 104.Pp 105With no arguments, the program 106.Nm cfscores 107prints out the current status of your canfield account. 108If a 109.Ar user 110name is specified, 111it prints out the status of their canfield account. 112If the 113.Fl a 114flag is specified, 115it prints out the canfield accounts for all users that have 116played the game since the database was set up. 117.Sh FILES 118.Bl -tag -width /usr/games/canfield -compact 119.It Pa /usr/games/canfield 120the game itself 121.It Pa /usr/games/cfscores 122the database printer 123.It Pa /var/games/cfscores 124the database of scores 125.El 126.Sh BUGS 127It is impossible to cheat. 128.Sh AUTHORS 129Originally written: Steve Levine. 130.Pp 131Further random hacking by: Steve Feldman, Kirk McKusick, 132Mikey Olson, and Eric Allman. 133
