Spider Solitaire: Complete Rules and Strategy Guide

Spider Solitaire is one of the most challenging and rewarding card games in the solitaire family. Named for the eight legs of a spider (representing the eight foundation piles that must be completed to win), this game uses two full decks of cards and requires both strategic thinking and patience. In this comprehensive guide, we will cover the rules for all three difficulty levels and share expert strategies to help you master each variant.

Overview: What Makes Spider Different

Unlike Klondike Solitaire, which uses one deck and four foundation piles sorted by suit, Spider Solitaire uses two decks (104 cards) and has ten tableau columns. The goal is to build complete sequences from King down to Ace in the same suit. When you complete a full King-to-Ace sequence in one suit, it is automatically removed from the tableau.

The game is won when all eight suits have been completed and removed — four of each suit in the two-deck game, or eight sequences in the suited variants.

Setup and Layout

Regardless of which variant you play, the initial layout is the same:

1. Tableau: 10 columns of cards are dealt face-down. The first four columns receive 6 cards each, and the remaining six columns receive 5 cards each. Only the top card of each column is face-up.
2. Stock: The remaining 50 cards form the stock pile at the bottom of the screen. These are dealt in groups of 10 (one card to each column) when the player chooses.
3. Foundation: Empty spaces where completed King-to-Ace sequences are placed. The game starts with no foundation piles visible — they appear as sequences are completed.

Basic Rules

Moving Cards

• You may move a single face-up card from one column to another if it is one rank lower than the card you are placing it on (regardless of suit).
• For example, you can place a 7 on any 8, or a Queen on any King.
• You may move a group of cards as a single unit only if they form a descending sequence of the same suit (e.g., 8♠ 7♠ 6♠ can be moved together, but 8♠ 7♥ 6♠ cannot).
• Any card or valid sequence can be placed in an empty column.

Dealing from Stock

• When no more moves are available (or when you choose), you may deal from the stock pile.
• Each deal places one card face-up on each of the 10 tableau columns.
• Important: You cannot deal from the stock if any column is empty. All columns must have at least one card before dealing.
• There are 5 deals available from the stock (50 cards ÷ 10 columns = 5 deals).

Completing Sequences

• When you build a complete descending sequence from King to Ace, all in the same suit, it is automatically removed from the game.
• The game is won when all 8 sequences have been completed and removed.
• The game is lost when no moves are available, the stock is empty, and no complete sequences can be formed.

1-Suit Spider: Rules and Strategy

In 1-Suit Spider, all 104 cards are the same suit (typically Spades). This is the most forgiving variant because every descending sequence is automatically same-suit, meaning you can always move groups of cards together.

Strategy for 1-Suit

• Focus on emptying columns: Empty columns are incredibly powerful in Spider. They act as temporary storage, allowing you to reorganise sequences and uncover hidden cards.
• Build long sequences early: Since all cards are the same suit, any descending sequence can be moved. Prioritise building longer sequences even if it means temporarily disrupting shorter ones.
• Clear columns before dealing: Always try to empty at least one column before dealing from the stock. This gives you immediate flexibility to handle the new cards.
• Complete sequences quickly: When you have a near-complete King-to-Ace sequence, prioritise finishing it to free up significant tableau space.

2-Suit Spider: Rules and Strategy

2-Suit Spider typically uses Hearts and Spades (one red, one black). This dramatically increases difficulty because you can no longer freely move all descending sequences — only same-suit sequences move as groups.

Strategy for 2-Suit

• Same-suit building is paramount: Always prefer placing a card on the same suit when possible, even if it means making a slightly less optimal move positionally.
• Avoid mixing suits in long columns: A column with alternating suits becomes essentially immovable. Each card must be moved individually, which is very slow.
• Use empty columns as sorting spaces: Move cards to empty columns to reorganise mixed sequences into same-suit runs.
• Plan several moves ahead: Before placing a card of a different suit, consider whether you will be able to separate the suits later.
• Prioritise uncovering face-down cards: Hidden cards are even more critical in 2-suit because you need specific suits, not just specific ranks.

4-Suit Spider: Rules and Strategy

4-Suit Spider is the ultimate challenge. With all four suits in play, building same-suit sequences becomes extremely difficult. Many experienced players consider a win rate above 15% to be excellent at this level.

Strategy for 4-Suit

• Accept imperfect moves: In 4-suit, you will often need to place cards of different suits on each other. This is unavoidable — the key is minimising it.
• Choose a "primary" suit: When possible, focus on completing one suit first. This frees up space that makes completing subsequent suits easier.
• Create empty columns at all costs: Empty columns are even more valuable in 4-suit because the reorganisation potential they offer is immense.
• Delay dealing as long as possible: Each deal adds complexity. Maximise your moves before dealing from the stock.
• Watch for partial sequences: Even building a partial same-suit run (e.g., K-Q-J-10-9 of one suit) gives you a movable block that provides tactical flexibility.
• Use undo liberally: 4-suit Spider is extremely difficult. Using undo to explore different paths is a valuable learning tool.

Scoring

The standard scoring system for Spider Solitaire works as follows:

• Starting score: 500 points
• Each move: -1 point
• Completing a suited sequence (King to Ace): +100 points
• Final score = 500 - (number of moves) + (completed sequences × 100)

A good score in 1-suit Spider is anything above 500 (meaning you completed the game efficiently). In 4-suit, simply finishing the game at all is an achievement, regardless of score.

Common Mistakes to Avoid

1. Dealing too early: Many beginners deal from the stock as soon as they feel stuck. Always exhaust all possible moves first — you may find options you initially missed.
2. Ignoring empty column creation: New players often fail to recognise how valuable empty columns are. Always work towards creating at least one.
3. Building tall mixed-suit columns: It feels productive to stack cards in descending order, but if the suits are mixed, you have created an immovable pillar that blocks progress.
4. Forgetting the stock rule: You cannot deal if any column is empty. Sometimes this means you need to place a card in an empty column you were saving, which feels wasteful.
5. Not looking at the whole board: Spider has 10 columns and 104 cards. Take time to scan the entire layout before each move. The optimal play might be in a column you were not focusing on.

Spider Solitaire Terminology

Tableau	The 10 columns where gameplay takes place
Stock	The remaining 50 cards that can be dealt in groups of 10
Sequence	A run of cards in descending order (e.g., 9-8-7-6)
Suited Sequence	A sequence where all cards are the same suit — can be moved as a group
Complete Sequence	A full King-to-Ace suited sequence (13 cards) — removed from game
Deal	Placing one card from stock onto each of the 10 columns
Empty Column	A tableau column with no cards — any card can be placed here

Tips for Beginners

If you are new to Spider Solitaire, we recommend the following progression:

1. Start with 1-suit: Play at least 20-30 games of 1-suit Spider to learn the mechanics and develop basic strategies.
2. Move to 2-suit when comfortable: Once you can win 1-suit games consistently (60%+ win rate), move to 2-suit. The suit-matching requirement adds a significant strategic layer.
3. Attempt 4-suit as a challenge: Only move to 4-suit after you are comfortable with 2-suit. Expect your win rate to drop dramatically — this is normal. Winning even 10% of 4-suit games indicates strong play.
