Spiderette Solitaire is a card game similar to Spider Solitaire. The primary difference is that Spiderette is played with a single deck, where Spider Solitaire is played with 2 decks. In Spiderette, 21 cards are initially dealt into 7 columns, with all but the top card face down. Cards may be moved between the columns, building them down from King to Ace regardless of suit. When a column has only 13 cards, and are arranged from King to Ace, the column is removed from the game. When all cards have been removed, the player wins.
