Spider Solitaire Empty Columns

An empty column is temporary workspace, not a random parking spot. Play the practice board, reveal first, protect same-suit mobility, and refill only when the next deal or run is ready. Regular browser games can save locally, so you can continue a run later from the same device.

Quick Answer

Spider Solitaire Empty Columns

An empty column in Spider Solitaire is temporary workspace. Use it to reveal face-down cards, move a King or valid same-suit sequence, and untangle mixed stacks without giving up future mobility. Fill the last empty column only when the move creates a clear reveal, rebuilds a stronger same-suit run, creates another useful space, or prepares a legal stock deal. Standard Spider only lets you deal from the stock when every tableau column is filled.

First-Party Evidence

Why empty-column workspace matters more as suits increase

Competitor strategy pages commonly tell players to preserve empty spaces. This page ties that advice to this site's own seeded opening-board data, while avoiding win-rate claims we have not measured.

Evidence	Observed value	Player takeaway
Opening-board study	75,000 seeded deals: 25,000 starts each for 1-suit, 2-suit, and 4-suit Spider.	This gives a baseline for opening mobility, not a win-rate claim about empty-column play.
Same-suit mobility split	1 suit averaged 6.46 same-suit top moves; 2 suits averaged 3.20; 4 suits averaged 1.61.	The more suit friction rises, the more valuable an empty column becomes as workspace for rebuilding movable runs.
Seeded 2-suit board	empty-columns-2s-b opened with 7 legal top moves, but only 2 same-suit moves.	A board can look active while still needing open space to avoid freezing mixed stacks.
Seeded 4-suit board	empty-columns-4s-b opened with 3 legal top moves and 1 same-suit move.	Hard-mode starts leave less clean mobility, so spending the last empty column casually is expensive.
Stock rule constraint	Standard Spider blocks stock deals until all 10 tableau columns contain a card.	An empty column is temporary leverage: use it for reveals or repairs, then refill deliberately before the deal.

Method note: the 75,000-deal study measured opening-board legal moves and same-suit top moves using this site's seeded shuffle and deal model. The seeded board examples are reproducible opening observations, not player-behavior data, full-game solvability tests, or ad hoc screenshots.

Decision Table

What to check before you move

Situation	Check first	Best action
A face-down card is blocked	Will using the empty column reveal a hidden card or unlock a stronger run?	Use the space for the reveal, then rebuild the column instead of parking a card there permanently.
A King or legal run can move	Does parking the King there free a column, expose a card, or improve suit order?	Move it into the empty column when it improves the tableau.
Mixed suits are tangled	Can the empty column separate the stack so you can rebuild same-suit sequences?	Use the space as temporary storage to untangle the stack.
A same-suit run is almost movable	Can one staging move turn scattered cards into a clean descending sequence?	Spend the empty column on the same-suit rebuild before making a weaker mixed-suit move.
It is your last empty column	Will filling it remove the last useful buffer before the next deal?	Preserve it unless the move clearly improves the board right now.
You are ready to deal from the stock	Are all tableau columns filled, and is the position still workable?	Fill the empty column only when you are ready to deal.

Quick Rule

Empty Columns Are Valuable Workspace

The open column is not dead space. It is a temporary lane that lets you move cards, free a King, reveal hidden information, and rearrange other columns until the board gives you a better shape. The goal is not to keep the column empty forever; the goal is to spend it on a move that improves the next few decisions.

Use empty columns to expose face-down cards.
Move a King or legal run when it advances the tableau.
Keep one open when the board still needs flexibility.

Rule vs Strategy

What is legal is not always the best use of the space

The rule is simple: any single card or valid same-suit sequence can move into an empty column. The strategy is stricter. Spend the space only when it reveals information, repairs a run, separates mixed suits, creates another column, or gets the tableau ready for a stock deal.

Legal move: any movable card or same-suit run into the empty column.
Strong move: a fill that changes the next board state in your favor.
Weak move: using the last open space with no reveal, repair, or deal plan.

Untangling

Break Mixed-Suit Stacks With Open Space

Mixed-suit stacks are hard to move as a unit. Empty columns let you split the stack, rebuild same-suit runs, and restore mobility without forcing a bad lock-in. This matters most in 2-suit and 4-suit Spider, where a move can be rank-legal but still make the stack harder to move later.

Separate mixed stacks before they trap your best cards.
Rebuild same-suit sequences after the shuffle.
Use the empty column as a staging area, not a permanent parking spot.

Evidence Note

Why Board Space and Same-Suit Mobility Matter

The site's June 2026 opening-moves study analyzed 75,000 seeded deals: 25,000 each for 1-suit, 2-suit, and 4-suit Spider. The data showed that legal top-card moves stayed similar by difficulty, while same-suit top-card mobility dropped sharply as more suits were added. That study did not measure empty-column outcomes, win rates, or full-game solvability. It supports a narrower takeaway for this page: use empty columns to preserve movable same-suit structure whenever the board gives you that option.

Study sample: 75,000 deterministic seeded opening deals.
Method: opening-board counts of legal top-card moves and same-suit top-card moves.
Practical takeaway: same-suit mobility is worth protecting when you spend an empty column.

Search Language

Empty spaces, vacant columns, empty piles, and holes

Players use different words for the same tableau state. In standard Spider Solitaire, an empty space, vacant column, empty pile, or hole usually means a tableau column with no cards in it. The tactical question stays the same: does filling it buy a reveal, a cleaner suit run, or a legal stock deal?

Use the phrase that matches the rule: empty tableau column.
Remember that Spider is more flexible than Klondike because any card can fill the space.
Do not confuse an empty tableau column with the foundation spaces where completed suits clear.

Stockpile

Standard Spider Requires Every Column Filled Before a Deal

In standard Spider Solitaire, every tableau column must be filled before you deal from the stock. That makes empty columns useful, but only until you are ready to stop using the workspace and commit to the next deal.

Do not deal while any tableau column is empty.
Use the open column first if it reveals a card or improves a run.
Fill the column only when the move is worth giving up the space.

FAQ

What can go in an empty column in Spider Solitaire?

Any single card or valid same-suit sequence can move into an empty column.

Why are empty columns important?

Empty columns give you temporary space to move cards, uncover hidden cards, separate mixed suits, and rebuild same-suit sequences. They are most useful when they increase mobility instead of simply holding a card.

Should I fill an empty column immediately?

Not always. Fill an empty column when it reveals a card, improves a run, or prepares a stock deal. Keep the last empty column open if you still need workspace.

Can you deal from the stock with an empty column?

No. Standard Spider Solitaire requires every tableau column to be filled before dealing from the stock.

Are empty spaces, vacant columns, and holes the same thing?

Usually yes. Players use empty spaces, vacant columns, empty piles, or holes to describe an empty tableau column in Spider Solitaire.

When should you not use an empty column?

Do not spend your last empty column on a move that reveals no card, repairs no sequence, creates no new space, and does not prepare a required stock deal.

Did the 75,000-deal study measure empty-column outcomes?

No. The study measured opening-board mobility, including legal top-card moves and same-suit top-card moves across 75,000 seeded deals. It supports the general value of preserving same-suit mobility and board space, but it did not test empty-column outcomes, win rates, or full-game solvability.
