Spider is a challenging (and time-consuming) game using two decks which was supposedly the favorite solitaire of FDR. While Spider has the usual objective of arranging all suits in order, Spider does not provide a stack for each suit to be assembled in. Instead, the suits must be ordered in the building stacks and are then moved to a discard pile. The game is won when all cards in both decks are in the discard pile. Stacks in Spider can be built with any suit, but multiple cards moved between stacks must all have the same suit. Several non-standard options have been implemented to make the game less daunting for beginners For more help, use the button within the game, or click here for Spider Solitaire help.
