Colorado Solitaire is a two deck solitaire card game played with 8 foundations. 4 of the foundations must be built up from Ace to King by suit, and the other 4 foundations must be built down from King to Ace by suit. The game is played with 20 piles, on which new cards can be placed without regard to rank or suit. The player has a stock pile and a waste pile, into which he may deal a single card at a time from the stock pile. When all the cards in a pile have been removed, the gap must be immediately filled with a card from the stock pile if there are still cards in the stock pile.
This game is NOT a gambling simulation. It is intended to be an entertaining
diversion, not a simulation of casino games.
