A Spider with no stock: the 52 cards are already dealt across ten columns. Build four complete King-to-Ace runs, each of one suit.
Spider is one of the most celebrated two-deck solitaires. Its name comes from the eight foundations you must complete — like a spider’s eight legs. It appears in patience collections from the early 20th century, when two-deck games grew popular for offering longer, more strategic play.
A frequently repeated story credits U.S. president Franklin D. Roosevelt as a fan — the anecdote is hard to verify, but it endures because Spider is famous for rewarding patience and calculation rather than luck.
Like Klondike, Spider exploded in popularity once it shipped with Windows (from Windows ME/XP, around 2001), becoming for many people the definitive “hard solitaire”.
