Spider Solitaire is one of the world's most popular versions of the card game solitaire. Unlike Klondike (or "regular") Solitaire, Spider Solitaire is played with two decks of cards. Stack cards into descending order (from King to Ace) to eliminate them from the tableau. Beat spider solitaire by eliminating all stacks of cards!

The main purpose of the game is to remove all cards from the table, assembling them in the tableau before removing them. Initially, 54 cards are dealt to the tableau in ten piles, face down except for the top cards. The tableau piles build down by rank, and in-suit sequences can be moved together. The 50 remaining cards can be dealt to the tableau ten at a time when none of the piles are empty.
