Colorado Solitaire is a 2 deck solitaire card game where the player has 2 piles that act as stacks. You can place cards onto these stacks in any order, but you have to take off the cards in the reverse order you put them on (the last card you put on is the first one you must take off). There are 8 suit piles across the top of the game screen. You must build down the piles on the left side of the game screen from King to Ace by suit, and build up the four suit piles on the right side from Ace to King by suit.
At the bottom of the game screen is a deck of cards. You can draw cards from the deck only one at a time. You can then place the card on stacks in the middle of the game screen, or move them to the suit piles at the top. If you remove all the cards from one of the stacks, you must deal the next card into that stack to start it off. I have a little peak at the card that's currently on the top of the deck next to it.
