Pro Spider Solitaire

Pro Spider Solitaire is a challenging version of the spider solitaire game. Like most versions of Spider Solitaire that are called "Single Suit", the player can build the cards down in the columns without regard to suit. In other words, the suit doesn't matter so you can treat all the cards as if they had the same suit. One of the features of Pro Spider Solitaire that makes the game more challenging, is that all but the top row of cards is turned face down at the beginning of the game. This makes it difficult for the player to know what columns of cards are optimal to move. There are also more cards turned facedown in the columns at the beginning of the game than there are in a typical game of Spider Solitaire.
