There are three possible variants spider solitaire. All three use the same basic rules, but the way the cards can be moved is slightly different for the easier version. It's probably best to explain the rules for the 4 suit version of the game first and then explain the changes for the easier two suit version and one suit version.
Rules for the 4 Suit Version
- A single card can only be moved to another pile if the card being moved is one less than the card it will be placed on. For example any 9 can be placed on any 10.
- Groups of cards can only be moved if they are all in same suit and are in perfect descending order. For example you could move a 10, 9 and 8 of diamonds as a group onto any open Jack.
- If a card that is face down in a column is open it must be turned over.
- Any group or single card you might be able to move can be placed on an empty column.
- You can deal 10 cards from the cards remaining, one to each column if you cannot make any moves. However there must be at least one card in each column when you do this.
- If you have a complete group of cards in one suit in perfect descending order it can be removed from play. For example King of Spades all the way down to the Ace of Spades. Remove all the cards to win the game.
2 Suit Version Rules
- This is common variant of spider solitaire seen in many computer versions. To simulate this using a 2 standard decks of cards just assume that all red cards are one suit and the other suit is all black cards. Now groups can be moved if they are in perfect descending order and they are all in the red suit or black suit. E.g. You could move a 10 of diamonds, a 9 of hearts and 8 of diamonds onto any open Jack.
- If you have a complete group of cards in one suit in perfect descending order it can be removed from play. For example all red cards starting from the King down to the Ace.
- All other rules are the same as the 4 suit version.
1 Suit Version Rules
- To simulate this using a 2 standard decks of cards just assume that all cards belong to the same suit.
- This means you can move any group of descending cards onto another appropriate card. E.g. a 6 of spades, 5 of diamonds, 4 of clubs can be moved onto any open 7.
- Any group of cards in perfect descending order from King to Ace can be removed from play.
- This version of Spider Solitaire is particularly easy, but it's quite relaxing!
