Spider Solitaire at its most challenging. The card game 4 Suit Spider Solitaire is played with two full decks of cards, making it the most difficult version of solitaire out there. Beat this puzzle game by stacking similarly-suited cards in descending order to make them disappear from the tableau. When you've gotten all 8 stacks (two decks worth) of cards eliminated, you've beaten this solitaire card game. Every time you win 4 Suit Spider Solitaire, your high score is displayed and automatically saved for you to play next time you get the chance to have a good time and blow off some steam on the work day. Spider Solitaire is a great way to cool down when you're hot on the job, and even better for a little unwind time. If you run out of cards while playing Spider Solitaire, just click the stock button conveniently located in the bottom-right of the screen. And, if you get stuck, just go ahead and click the undo button as many times as you like until you get back on track!
