One suit Spider Solitaire is a great way to begin to learn how the game is played. With some experience under your belt, you can challenge yourself with 2 or 4 Suit Spider Solitaire.

Luckily, in 2 and 4 Suit Spider Solitaire, the general layout is the same, and the rules do not vary too much. Again, two decks will be used. In 2 Suit, 54 cards of two suits are used. In 4 Suit, 26 cards of each suit are used. Layout the cards the same you would for a single suit. After this, follow these general rules:
Apply the same card-moving rules from single to multi suit
You can only move groups of cards as a single unit if they are in sequential order and of the same suit
You can sequence cards of different colors or suits. However, you can only move cards together, or as a bunch, to other piles if they are of the same suit. If you move a 4 of Hearts on top of a 5 of Spades, the 5 of Spades is blocked until the 4 of Hearts is moved. They cannot be moved together as a group.
sequence after block
Empty columns or piles can be filled by any card, just like single suit

The rest of the same rules apply 1 Suit, and the game is won when the foundation piles are filled. In 4 Suit, this means 2 foundation piles of each suit is completed, and in Two suits, 4 foundation piles of two suits are completed.

Adding more suits adds more difficulty to the game. More suits mean more careful thinking when planning out your next move, because a small accident can trap in a card that you needed desperately! There is also higher likelyhood that you won’t win the game as more suits are added.
