Spider is a patience card game payed with 2 decks of cards. The name comes from the eight foundation piles in which complete suits are placed. Initially 54 cards are dealt into 10 tableau piles and the top card of each pile is turned face up.

Card are moved between tableau piles until a complete suit from king to ace is built, and then that suit is moved to the foundation. A card can be placed in a tableau when the top card is one face higher than the card being moved. Only a series cards of the same suit can be moved between piles.

The game can be difficult to solve with 4 suits, for that reason options are given to play with 2 or 1 suits.
