Grandfather (solitaire)

Grandfather is a solitaire card game within KPatience. According to the KPatience documentation, there is no other known software implementing this game. While there are other solitaire games with names including Grandfather, including Grandfather's Clock and Grandfather Solitaire (http://www.bvssolitaire.com/rules/grandfather.htm), these games do not have comparable rules. As such, the remainder of this article shall describe Grandfather as implemented by KPatience.

The player deals one deck to seven playing piles while some cards on each pile are face down on initial deal. The goal of Grandfather is to "put all cards as real families ascending on the foundations".

You can move every card on every pile if it fits on another card to build a real sequence in descending order. For example, you can move the five of spades on top of the six of spades, no matter how many cards on are on top of the five of spades. The six of spades must be on top of its pile. On any free pile you may place a king (again no matter how many cards are on top of it).

If no more cards can be moved, you can re-deal up to two times. All cards already in the foundations stay there, but the cards in the playing piles are reordered to give you a new chance to find a solution.
