Spider Solitaire is an online destination for playing the classic single-player card game for free. The game runs in a browser, can be played full-screen, and requires no registration or download. Players can choose from several versions, including One Suit for a simpler game, Two Suits for greater challenge, Four Suits for experienced players, and Scorpion. The site also offers detailed game statistics and interface tools such as New Game, Start Over, Undo Move, and Suggest Move.

Spider Solitaire’s guides explain the game’s history, setup, rules, and strategies. The objective is to arrange cards into eight same-suit sequences, running from King to Ace, and clear them from the tableau. The site recommends planning moves before using the stock, opening empty piles, and building same-suit sequences where possible. Available in multiple languages, the service is designed for play on different platforms, including mobile phones. It also provides account access, bookmarking, and information about the game’s rules and benefits.
