Stockpile Strategy
Use the stock only after the tableau has stopped giving you useful information, space, or same-suit mobility. Practice the decision on a playable board before the next long scroll. Regular browser games can save locally, so you can continue a run later from the same device.
Quick Answer
Deal from the stock only after useful tableau moves are exhausted and every tableau column is filled. Wait if you can still reveal a hidden card, preserve or build a same-suit run, create useful empty-column space, or repair an empty column deliberately. The stock is for a stuck legal board, not for skipping a hard scan.
Decision Table
| Situation | Check first | Best action |
|---|---|---|
| No useful tableau moves | Nothing improves access, same-suit order, or column space after a final scan. | If every tableau column is filled, deal from the stock. |
| Hidden-card reveal available | A move can turn a face-down card face up. | Make the reveal first. |
| Empty column exists | At least one tableau column is open. | Do not deal; fill the empty column first. |
| Same-suit move available | A move keeps or builds a same-suit stack that can move again later. | Use the same-suit move before dealing. |
| Mixed-suit move is legal | The move fits by rank, but it may bury a cleaner same-suit option. | Take it only if it reveals, opens space, or prevents a worse lock-up. |
| Board is stuck | No useful moves remain and every tableau column is filled. | Deal from the stock. |
| Last stock deal | Only one 10-card deal remains in the stock. | Use every reveal, same-suit move, and empty-column repair before spending it. |
Before Dealing
The stock pile is powerful but expensive because one card lands on every column. Before clicking it, scan the board for moves that improve information, mobility, or column space. If the scan finds a useful move, wait.
Risk
A stock deal places one new card on every column. That can help a stuck board, but it can also bury clean runs and force you into mixed-suit stacks. The right deal is the one you make after the tableau has stopped offering better work.
Rule
Standard Spider Solitaire requires every tableau column to be filled before you deal from the stock. An empty column is not a stock-timing loophole; it is workspace you must either use or refill before the next deal becomes legal.
Evidence Note
The site's June 2026 opening-moves study tested 75,000 deterministic seeded opening deals: 25,000 each for 1-suit, 2-suit, and 4-suit Spider. The method used the live game's deck model and measured opening-board availability, including legal top-card moves, same-suit top-card moves, and first-stock-row potential moves. It did not test full stock-timing outcomes, win rates, or solvability.
Same-Suit Mobility
The same study found that average rank-legal opening moves were nearly identical across modes, while same-suit top-card moves dropped from 6.46 in 1 suit to 1.61 in 4 suits. That supports a practical stock-timing habit: protect clean same-suit mobility before adding 10 more cards, especially in 2-suit and 4-suit games.
Mode Practice
The stock rule stays the same across standard Spider modes, but the cost of a bad deal rises as more suits enter the board. Start in 1 suit to learn the rhythm, use 2 suits to practice separating two suit families, and use 4 suits when you can preserve same-suit mobility under pressure.
Final Deal
Once the last 10 cards are dealt, there is no refill. Before the final stock click, protect movable same-suit runs, avoid burying low cards, and make sure each empty column has already done useful work.

Deal only after useful tableau moves are exhausted, every column is filled, and you have checked for hidden-card reveals, same-suit mobility, and empty-column opportunities.
No. Standard Spider Solitaire requires every tableau column to be filled before you deal from the stock.
Dealing too early adds 10 new cards and can bury useful sequences, block hidden-card reveals, and make mixed-suit stacks harder to untangle.
No. The study measured opening-board mobility and first-stock-row potential moves across 75,000 seeded deals. It supports the value of preserving same-suit mobility before a deal, but it did not test full stock-timing outcomes, win rates, or solvability.
Before the final stock deal, use every useful tableau move you can find, preserve same-suit runs, refill empty columns, and avoid burying cards you still need for a King-to-Ace sequence.
Use 1 suit to learn the habit, 2 suits to practice suit discipline, and 4 suits when you are ready for stricter stock timing decisions.
