What Is Spider Solitaire?
Spider Solitaire is one of the most popular card games in the world, second only to Klondike Solitaire in terms of worldwide players. It gets its name from the eight legs of a spider, representing the eight foundation piles you must complete to win the game. Unlike most solitaire variants that use a single deck, Spider Solitaire uses two full standard decks of 52 cards each, giving you 104 cards to work with.
The game rose to massive popularity when Microsoft included it in Windows ME in 2000, and later in Windows XP. Millions of office workers and home computer users discovered the addictive challenge of organizing cards into descending same-suit sequences. Today, Spider Solitaire remains one of the most-played card games online and on mobile devices, with several difficulty levels that make it accessible to beginners while still challenging for experienced players.
What makes Spider Solitaire unique among solitaire games is the combination of its large tableau (10 columns), the dual-deck setup, and the requirement to build same-suit sequences for completion. While you can stack cards of any suit during play, only same-suit runs from King to Ace are removed from the board. This creates a rich strategic landscape where you must constantly balance short-term moves against long-term goals.
Spider Solitaire comes in three standard difficulty levels: 1-suit, 2-suit, and 4-suit. Each level dramatically changes the strategy and win probability, giving players a progression path from beginner to expert. Whether you are picking up the game for the first time or looking to master the 4-suit variant, this guide covers everything you need to know.
The Layout: Tableau, Stock, and Foundations
Understanding the three areas of the Spider Solitaire board is essential before you start playing. Each area serves a distinct purpose, and knowing how they interact is the foundation of good strategy.
The Tableau (10 Columns)
The tableau is the main playing area and consists of 10 columns of cards. At the start of the game, 54 cards are dealt across these columns: the first four columns receive 6 cards each (24 cards total), and the remaining six columns receive 5 cards each (30 cards total). In each column, only the top card is dealt face-up; all others are face-down.
The tableau is where all the action happens. You build descending sequences here, rearrange cards to uncover hidden ones, and assemble complete King-to-Ace runs. Managing the 10 columns effectively is the core skill of Spider Solitaire. Empty columns are particularly valuable because they give you temporary storage space to maneuver cards around the board.
The Stock Pile (50 Cards)
After dealing 54 cards to the tableau, the remaining 50 cards form the stock pile. The stock is divided into 5 deals of 10 cards each. When you choose to deal from the stock, one card is placed face-up on top of each of the 10 tableau columns simultaneously.
Dealing from the stock is a critical decision point. Each deal adds 10 new cards to the board, which can open up new possibilities but also bury cards you were working with. The key rule to remember: you cannot deal from the stock if any tableau column is empty. All 10 columns must contain at least one card before a deal is allowed.
The Foundations (8 Piles)
The foundation area holds completed sequences. When you build a complete descending sequence of 13 cards from King to Ace, all of the same suit, those cards are automatically moved to a foundation pile and removed from play. Since you are working with two decks (8 suits total), you need to complete 8 foundation piles to win.
Unlike FreeCell or Klondike where you build foundations card by card from Ace up to King, Spider Solitaire foundations are filled all at once when a complete same-suit sequence is assembled in the tableau. You never manually move individual cards to the foundations.
Rules of Spider Solitaire
Spider Solitaire has a relatively simple set of rules, but the interactions between them create deep strategic complexity. Here are the complete rules:
Rule 1: Building Down
You may place any face-up card on top of another face-up card that is exactly one rank higher, regardless of suit or color. For example, a 7 of Hearts can be placed on an 8 of Clubs, an 8 of Spades, an 8 of Hearts, or an 8 of Diamonds. The only requirement is that the card being placed is one rank lower than the card it is being placed on.
Rule 2: Moving Groups
You can move a group of cards together only if they form a descending sequence of the same suit. For instance, if you have 9-8-7-6 of Spades in sequence, you can move all four cards as a group to any 10. But if the sequence is 9 of Spades, 8 of Hearts, 7 of Spades, you would need to move each card individually because the suits are mixed.
Rule 3: Empty Columns
Any face-up card or valid same-suit group can be moved to an empty column. Empty columns function as temporary storage, much like free cells in FreeCell. They are one of your most powerful tools and should be used strategically.
Rule 4: Revealing Cards
When all face-up cards are removed from a tableau column, the top face-down card is automatically turned face-up. Uncovering hidden cards is one of the primary objectives during play, as you cannot see or use face-down cards.
Rule 5: Dealing from Stock
Clicking the stock pile deals one card face-up to each of the 10 tableau columns. This can only be done when no tableau column is empty. There are 5 stock deals available (50 cards / 10 columns = 5 deals).
Rule 6: Completing Sequences
When you build a complete descending sequence from King to Ace of the same suit within a tableau column, all 13 cards are automatically removed and placed on a foundation. You need to complete 8 such sequences (two per suit, since you have two decks) to win the game.
Difficulty Levels: 1-Suit, 2-Suit, and 4-Suit
Spider Solitaire offers three distinct difficulty levels, each fundamentally changing the game experience. The difference is not just cosmetic — each level requires different strategies and produces vastly different win rates.
1-Suit Spider
All 104 cards are Spades. Since every card is the same suit, any descending sequence can be moved as a group and any complete King-to-Ace run qualifies for removal. This eliminates the suit-matching puzzle entirely, letting you focus purely on sequencing and column management.
2-Suit Spider
Uses two suits: Spades and Hearts (52 cards of each). You now need to pay attention to suit when building sequences. You can still stack any card on any card of the next higher rank, but only same-suit sequences can be moved as groups or completed. Mixed-suit stacking becomes a tactical tool rather than a path to completion.
4-Suit Spider
Uses all four suits: Spades, Hearts, Diamonds, and Clubs (26 cards of each). With four suits in play, building same-suit sequences becomes significantly harder. You must carefully manage which suits you mix when stacking, as breaking up a same-suit run to make a short-term move can be very costly.
The difficulty progression is dramatic. One-suit Spider is often considered a relaxing, almost meditative game that most players can win consistently. Four-suit Spider, on the other hand, is one of the most challenging solitaire games in existence, rivaling or exceeding the difficulty of games like FreeCell. Two-suit Spider sits comfortably in the middle, offering a satisfying challenge without the punishing difficulty of the full four-suit game.
Step-by-Step Guide to Playing Spider Solitaire
Here is a complete walkthrough of how a game of Spider Solitaire unfolds, from the initial deal to the final card.
Select Your Difficulty
Choose between 1-suit, 2-suit, or 4-suit. If you are new to Spider Solitaire, start with 1-suit. You can always increase the difficulty once you are comfortable with the mechanics. Our Spider Solitaire game lets you switch between difficulties at any time.
Survey the Initial Layout
Before making any moves, scan all 10 columns and note which cards are face-up. Look for immediate opportunities: cards that can be stacked in sequence, columns where a single move will reveal a hidden card, and any Aces or Kings in useful positions.
Start Building Sequences
Begin by making moves that uncover face-down cards. Prioritize columns with fewer face-down cards, as these are easier to clear. Build descending sequences in the same suit whenever possible, but do not hesitate to make off-suit stacks if it helps uncover hidden cards.
Create Empty Columns
Try to empty at least one column as early as possible. Empty columns serve as temporary holding spaces, allowing you to rearrange long sequences and access deeply buried cards. The more empty columns you have, the more flexibility you have to reorganize the board.
Deal from Stock Strategically
When you have exhausted all productive moves in the current layout, deal a new row from the stock. Before dealing, try to arrange your columns so that the new cards have the best chance of being useful. Remember that dealing fills every empty column, so you may want to fill empties with Kings before dealing.
Assemble Complete Runs
As the game progresses, focus on assembling complete King-to-Ace same-suit sequences. Each completed sequence is automatically removed, freeing up space on the board. Completing even one sequence early can dramatically open up the game by reducing the number of cards you need to manage.
Manage the Endgame
After all stock deals have been used, you must work with the remaining tableau cards. This endgame phase requires careful planning, as every move counts. Prioritize completing partial same-suit sequences and use empty columns to shuffle cards into their final positions.
Complete All Eight Sequences
The game is won when you have built and removed all eight King-to-Ace same-suit sequences. With two decks containing four suits each, that is two complete sequences per suit (or eight sequences of one suit in 1-suit mode).
Tips for Beginners
If you are just getting started with Spider Solitaire, these tips will help you develop good habits from the beginning and avoid common pitfalls that trip up new players.
- Always start with 1-suit. There is no shame in playing the easiest variant. One-suit Spider teaches you the fundamental mechanics — sequencing, column management, stock timing — without the added complexity of suit matching. Master 1-suit first, then move to 2-suit.
- Uncover face-down cards early. Your top priority in the opening should be revealing hidden cards. The more cards you can see, the better decisions you can make. Target columns with the fewest face-down cards for quick reveals.
- Value empty columns highly. An empty column is worth more than almost any other advantage on the board. It gives you a place to temporarily store cards while you rearrange sequences. Avoid filling empty columns unless you have a clear strategic reason.
- Build same-suit sequences when possible. Even in 1-suit mode, get into the habit of thinking about suit consistency. In 2-suit and 4-suit modes, mixed-suit stacks are much harder to disassemble later. Same-suit sequences are always preferable.
- Do not rush to deal from the stock. Each deal adds 10 cards to the board, which can bury useful cards and create new problems. Exhaust all productive moves in the current layout before dealing. The longer you can play without dealing, the more control you maintain.
- Use undo liberally. In our online Spider Solitaire, you can undo moves freely. Use this feature to explore different lines of play. Try a sequence of moves, see where it leads, then undo and try a different approach. This is the fastest way to develop strategic intuition.
- Think several moves ahead. Before making a move, ask yourself: what does this enable? If moving a card reveals a hidden card, great. If it builds toward a same-suit sequence, great. If it just rearranges the board without making progress, it might not be worth it.

A Brief History of Spider Solitaire
Spider Solitaire has a surprisingly rich history. The game first appeared in print in 1949 in the book Games of Patience. The name "Spider" was chosen because of the eight foundation piles needed to win, corresponding to the eight legs of a spider.
The game remained a niche card game played with physical decks until Microsoft included it as a free game in Windows ME (Millennium Edition) in 2000. This single decision exposed hundreds of millions of computer users to Spider Solitaire, making it one of the most-played computer games of all time. Microsoft later included an improved version in Windows XP, Windows Vista, and subsequent Windows releases.
The Windows version popularized the three difficulty levels (1-suit, 2-suit, 4-suit) that have since become standard across all digital implementations. Before the Microsoft version, Spider was typically played with two full four-suit decks only, which is extremely challenging. The 1-suit and 2-suit variants were innovations that made the game accessible to a much wider audience.
Today, Spider Solitaire is available on virtually every platform: web browsers, smartphones, tablets, and desktop computers. It consistently ranks among the top card games in app store download charts and has spawned numerous variations and tournament formats.
Frequently Asked Questions
How many cards are used in Spider Solitaire?
Spider Solitaire uses two standard 52-card decks shuffled together, giving you 104 cards total. These are dealt into 10 tableau columns (54 cards) with the remaining 50 cards placed in the stock pile.
What is the difference between 1-suit, 2-suit, and 4-suit Spider Solitaire?
The difference is how many suits are in the deck. In 1-suit Spider, all 104 cards are Spades, making it the easiest variant. In 2-suit Spider, you play with Spades and Hearts (52 cards of each). In 4-suit Spider, you use all four suits, making it the most challenging version because completed sequences must be entirely of one suit.
Can you move any card onto any other card in Spider Solitaire?
You can place any card that is one rank lower onto another card in the tableau, regardless of suit. For example, a 5 of Hearts can go on a 6 of Clubs. However, you can only move a group of cards together if they form a descending sequence of the same suit. Mixed-suit sequences must be moved one card at a time.
When can you deal new cards from the stock in Spider Solitaire?
You can deal a new row of cards from the stock at any time, but there is one important rule: every one of the 10 tableau columns must contain at least one card. You cannot deal from the stock if any column is empty. Each deal places one card on top of each of the 10 columns.
What happens when you complete a full sequence in Spider Solitaire?
When you build a complete descending sequence from King down to Ace, all of the same suit, those 13 cards are automatically removed from the tableau and placed on a foundation pile. The goal is to remove all eight such sequences (since you have two full decks).
Is every Spider Solitaire game winnable?
No. Unlike FreeCell where nearly 99.999% of deals are solvable, Spider Solitaire has a lower win rate that varies by difficulty. Experienced players can win roughly 99% of 1-suit games, around 50-60% of 2-suit games, and only about 10-35% of 4-suit games. Many deals are mathematically unsolvable regardless of how well you play.
How do you win Spider Solitaire?
You win Spider Solitaire by removing all 104 cards from the tableau. This requires building and completing eight full sequences of 13 cards each, running from King down to Ace in the same suit. Once all eight sequences are assembled and moved to the foundations, the game is won.
What is the best Spider Solitaire variant for beginners?
One-suit Spider Solitaire is the best starting point for beginners. Since every card is the same suit, you never have to worry about suit matching when building sequences. This lets you focus on learning the mechanics of the game, understanding when to deal from the stock, and developing basic strategic thinking before moving on to 2-suit or 4-suit.
Can you undo moves in Spider Solitaire?
In most digital versions of Spider Solitaire, including our online version, you can undo moves freely. This is a great learning tool that lets you experiment with different strategies without penalty. Some competitive players choose to limit their undos for an extra challenge.
How long does a game of Spider Solitaire take?
A typical game of 1-suit Spider Solitaire takes 5 to 15 minutes for an experienced player. Two-suit games usually take 10 to 25 minutes, and 4-suit games can take 20 to 45 minutes or more due to the increased complexity. Beginners should expect games to take longer as they learn the strategies.
