Spider Solitaire

Spider Solitaire uses two decks (104 cards) and is played with 10 tableau columns. It's considered more challenging than Klondike.

• Deal 54 cards into 10 columns: the first 4 columns get 6 cards, the remaining 6 columns get 5 cards. Only the top card of each column is face-up.
• The remaining 50 cards form the stock, divided into 5 deals of 10 cards each.
• Build tableau columns in descending order. You can place any card on a card that's one rank higher, regardless of suit.
• Only same-suit descending sequences can be moved as a group.
• When a complete King-to-Ace sequence of the same suit is formed, it's automatically removed from play.
• To deal from the stock, all 10 tableau columns must contain at least one card.
• The game is won when all 8 complete sequences have been removed.

• Build same-suit sequences whenever possible, even if it means making fewer moves.
• Try to empty a column before dealing from the stock — empty columns are extremely valuable.
• Use off-suit builds as temporary storage, but plan to reorganize them later.
• Focus on completing one sequence at a time rather than partially building several.
• Avoid dealing from the stock until you've exhausted all useful tableau moves.

1-suit Spider uses only spades and is the easiest. 2-suit uses spades and hearts for a moderate challenge. 4-suit uses all four suits and is extremely difficult, with only about 1-2% of games being winnable.

No. Approximately 79% of Klondike Solitaire deals are winnable with perfect play. FreeCell has a near-perfect solvability rate of 99.999%, while Spider Solitaire 4-suit has a very low win rate of about 1-2%.

Standard Klondike, FreeCell, and most variants use one 52-card deck. Spider Solitaire and Forty Thieves use two decks (104 cards).
