Spider Solitaire is a popular card game played with two decks of standard playing cards. The objective is to arrange all cards in descending order from King to Ace in eight foundation piles. Players can move cards between columns, but only cards of the same suit can be stacked together. To win, you must clear all the cards from the tableau. The game offers different difficulty levels, with one, two, or four suits. Spider Solitaire is not only a fun way to pass the time but also helps improve strategic thinking and problem-solving skills.
