Spider Solitaire requires sorting two decks of cards — a total of 104 – in each game. At the start, 54 cards are dealt in four columns of six cards and six columns of five cards, with the top card of each column facing up. The goal is to carefully stack the cards. After all, every game of Solitaire is really a fun method to clean up the house. To clean the board, you must have a full suit of cards, from ace to king. If you only use one suit, Spider Solitaire is simple enough. When you add a second suit, or all four, the game becomes more challenging. That's because you can't move a stack of numerically ordered cards if they're from different suits - only if they're all from the same suit. This adds a degree of complexity to Spider Solitaire, making it both the easiest and the most difficult version of the game, depending on how many suits you play with.
