Spiderette Solitaire is a solitaire card game similar to Spider Solitaire. The primary difference is that Spiderette Solitaire is played with a single deck, and Spider Solitaire is played with 2 decks. In Spiderette Solitaire, 21 cards are initially dealt into 7 columns of 3 cards each. All but the top card in each column is 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.
