Stock Rule
Learn when the stock can be dealt, why empty columns block a deal, and how to use the 50-card stock pile without burying useful moves.
Overview
Standard Spider Solitaire uses a 50-card stock. You get five stock deals, and each deal places one face-up card on every tableau column. You cannot deal while any column is empty. After the fifth stock deal, the stock is gone and you must finish with the cards already on the tableau.
Direct Rule
The stock deal touches every tableau column. Because of that, standard Spider Solitaire requires each of the 10 columns to contain at least one card before the stock can be used. If the stock button appears blocked, scan for an empty column first.
Card Count
A standard Spider Solitaire layout starts with 54 cards in the tableau. The remaining 50 cards stay in the stock, split into five 10-card rows. Each stock click places one new face-up card onto each tableau column.
Timing
A stock deal can rescue a stuck board, but it can also bury same-suit runs and turn clean columns into mixed-suit clutter. Use the tableau first when it can still reveal cards, protect sequence mobility, or make an empty column useful before the next row lands.
Study Context
The site's June 2026 opening-board simulation used 75,000 seeded deals: 25,000 each for 1-suit, 2-suit, and 4-suit Spider. Across the sample, the first stock row created about 7.15 to 7.17 rank-fit possibilities on average. That sounds useful, but same-suit mobility still fell sharply as suits increased.
Practice Path
The embedded board starts in 1-suit mode so the stock rule is easy to see. Once you can remember the filled-column rule and the five-deal count, move to 2 suits and 4 suits where a legal stock row can create more mixed-suit cleanup work.
Endgame
Once all 50 stock cards have been dealt, there is no refill. At that point, your job is to work the visible tableau carefully, keep space open for final runs, and avoid splitting same-suit sequences without a clear reason.
The usual reason is an empty tableau column. Standard Spider Solitaire requires all 10 columns to contain at least one card before the stock can deal the next 10 cards.
A stock click deals 10 face-up cards: one new card onto each of the 10 tableau columns.
No. Standard Spider Solitaire requires every tableau column to contain at least one card before you deal from the stock.
You get 5 stock deals. The stock contains 50 cards, and each deal places 10 cards, one onto each tableau column.
Deal only after you have checked for useful tableau moves, hidden-card reveals, same-suit builds, and empty-column opportunities.
There are no more stock deals. Keep working the tableau, use open columns carefully, and focus on uncovering or completing the remaining runs.
Yes. After 5 stock deals, all 50 stock cards have been added to the tableau. From that point, you must win with the cards already visible or uncoverable on the board.
No. The study measured opening-board mobility and first-stock-row potential moves, not full stock-timing outcomes. It supports a narrow takeaway: the first stock row usually adds rank-fit possibilities, but it can still bury useful same-suit structure.
The embedded practice game starts from the deterministic 1-suit seed stock-rules-practice-1-suit. It is a repeatable board for practicing the rule, not a claim that the board is representative of every deal.
