An empty column in Spider Solitaire can hold a card or an entire movable run, making it the board’s most flexible workspace. The objective is not only to create one. You want to use it for a specific rearrangement and then recover it for the next problem.
Why is an empty column so powerful?
Mixed-suit boundaries split otherwise descending runs. An empty column lets you remove the cards above a boundary, connect the suited cards below it, and rebuild the temporary stack. It is a dismantling station, not merely a destination for a King.
Which column should you empty first?
Prefer a column with few face-up cards, known destinations for those cards, and a face-down card that will turn after the transfer. A short column is not automatically best if its top cards have nowhere to go.
A five-stage method
- Identify the same-suit segment at the top of the target.
- Reserve a legal destination for that segment.
- Park the remaining mixed cards on other columns.
- Turn the newly exposed card and reassess.
- Rebuild temporary cards and recover the empty column when possible.
What should enter an empty column?
Choose a run that can move again. A long suited sequence or a short sequence with a visible future destination is easier to recover. A high mixed run with several suit boundaries can occupy the space for the rest of the deal.
What should happen before a stock deal?
Finish useful suited joins and reveals before new cards cover every column. If the implementation requires every column to contain a card, fill the empty one with the easiest run to recover and already know its next destination.
How does suit count change the plan?
One-suit Spider makes rank order and suited order nearly identical, so it is useful for learning the empty-column cycle. Two and four suits create more boundaries and make the column primarily a splitting tool. Compare the modes in the one-, two-, and four-suit guide.
Common empty-column mistakes
- Choosing the target without destinations for each card.
- Filling the space with a mixed run that cannot move again.
- Dealing while useful suited joins remain.
- Completing one run at the cost of every working column.
