Klondike, FreeCell and Spider: why similar cards need different plans

Hidden cards and stock change the information

Standard Klondike uses 52 cards, with only the front card of each of seven tableau columns face up and 24 cards in the stock. Revealing a hidden card gives you information you did not previously have. The waste also limits immediate access to its front card.

Standard FreeCell deals all 52 cards face up across eight columns, with no additional stock. Seeing a card does not mean it is accessible: cards in front of it still need to move. Standard Spider uses 104 cards, ten columns with only their front cards face up, and fifty stock cards for later deals. Stages may begin from shorter positions, so these counts describe standard openings rather than every board you encounter.

Groups obey different movement conditions

Klondike and FreeCell both require descending alternating-color groups. FreeCell adds a capacity limit based on free cells and empty columns excluding the destination. Klondike does not impose that temporary-storage calculation on a legal tableau group.

Spider permits placement onto a card one rank higher in any suit, but a movable group must descend within one suit. A red eight, black seven, red six group satisfies the color pattern for Klondike and FreeCell. It cannot be a same-suit Spider group. Rather than reusing a familiar visual pattern, check what connects the selected cards in the game you are playing.

What can enter an empty column?

An empty Klondike column needs a King or a legal King-led group. FreeCell and Spider allow legal groups beginning with other ranks. FreeCell still applies its capacity limit, and an empty destination cannot also count as a helper column.

For example, with two free cells and one empty column in FreeCell, the capacity for a move into that sole empty column is three cards. Red eight, black seven, red six fits if it is a selectable group. The same group cannot enter an empty Klondike column because it starts with an eight. In Spider, face-up spade eight, spade seven, spade six can enter an empty column as a same-suit group. Similar-looking gaps offer different opportunities.

New-card access works differently

Klondike draws one or up to three cards into the waste and permits play only from its front. When the stock empties, the remaining waste can be recycled without a pass limit. Recycling and drawing are separate actions. Useful waste removals can alter the boundaries of later draw-three packets.

FreeCell has no stock to turn to. Temporary parking in cells and reorganizing columns provide access instead. Spider adds one card to each of its ten columns per stock deal and forbids that deal while any column is empty. New cards are not an automatic rescue: an incoming row can cover a connection you were planning to use.

Choose practice by the completion goal

Klondike and FreeCell finish by building four suit foundations upward from Ace to King. Spider finishes by forming eight same-suit King-to-Ace runs in the tableau; completed runs are collected automatically. In the first two games, moving a card toward a foundation is a distinct action. In Spider, keeping and extending a descending run is part of the completion plan itself.

Choose Klondike to practice revealing hidden cards and managing waste access; FreeCell to practice transferring visible cards with temporary space; and Spider to practice building movable same-suit groups. Those are differences in the implementations, not a ranking of difficulty or a claim about win rates. Each legal move still needs to be assessed in the context of the remaining position, and none of these short checks guarantees a win.

Questions and answers

Does FreeCell need a King for an empty column?

No. Any rank can start a legal group there, subject to the group capacity limit.

Does Spider send Aces to foundations?

No. Build a same-suit thirteen-card descending King-to-Ace run in a column. Eight automatically collected runs complete the game.
