Short answer: Strong solitaire play protects future options. Prefer moves that reveal useful information, release a constrained card, create working space, or preserve a route for later cards. Avoid consuming an empty column, free cell, or accessible waste card without a concrete gain. The best choice depends on the variant: Klondike manages hidden cards and stock access, Spider manages suit structure and row deals, and FreeCell manages visible dependencies and workspace.

A legal-move list answers “What can I do?” Strategy asks “What becomes possible after I do it?” That distinction is essential because many losing positions are not caused by one obviously illegal action. They emerge from several legal actions that gradually remove mobility.

This guide offers a decision framework rather than a promise. Solitaire deals differ, and no priority rule is correct in every position. Use the principles to compare candidate moves, then adapt them to the exact cards you can see SRC-001.

The four resources behind most solitaire decisions

1. Information

Information is knowledge about cards and future access.

In Klondike and Spider, uncovering a face-down card adds information and often creates a new move. In Draw 3, learning the order of waste cards lets you plan which exposed card must move first. In FreeCell, every card is already visible, so the information task becomes dependency mapping: which cards block the Aces, low ranks, or empty-column opportunities?

A move that reveals a card is usually more valuable than a move that merely rearranges an already accessible sequence. “Usually” matters: revealing a card by occupying the only useful empty column may still be a poor exchange.

2. Mobility

Mobility is the number and quality of useful moves available after your current move.

Empty columns, empty free cells, exposed low cards, and movable Spider runs all create mobility. A board with many legal moves can still have low strategic mobility if those moves recycle the same cards without unlocking anything.

Ask not only how many spaces are empty, but what they can do:

  • an empty Klondike column needs a King-led move;
  • an empty Spider column can split a mixed stack;
  • an empty FreeCell column can support sequence transport;
  • an empty free cell stores one temporary card SRC-001.

3. Order

Solitaire is a dependency problem. Cards needed early may begin under cards needed late. Strategy changes that order through temporary placements.

A red 5 trapped under a black King may be needed to place a black 4, which in turn blocks an Ace. The immediate visual target is the Ace, but the operational target is the sequence of blockers above it.

In Draw 3, order also exists in the waste. Playing one top card changes which lower card becomes available and can change the alignment of later passes.

4. Reversibility

A reversible move can be undone in principle through ordinary legal play. An irreversible or costly move changes information, commits a scarce space, or changes the future card stream.

Examples of relatively reversible actions:

  • shifting a FreeCell card between two legal tableau destinations while cells remain open;
  • moving a Klondike alternating sequence between compatible columns;
  • using an empty Spider column temporarily and restoring it before a stock deal.

Examples of more consequential actions:

  • dealing a new Spider row;
  • filling the last empty FreeCell workspace without an exit;
  • sending a needed low tableau card to a foundation;
  • changing Draw 3 waste access by removing a card;
  • placing a King into an empty Klondike column that cannot soon be cleared.

Undo can reverse interface history, but the strategic question remains: could you have recognized the commitment before making it?

A practical move-evaluation method

For each serious choice, compare the candidate moves using five tests.

Test 1: What does the move unlock?

Name the gain precisely:

  • “reveals one face-down card”;
  • “exposes the black 6 needed for the red 5”;
  • “empties a column”;
  • “joins two same-suit Spider segments”;
  • “frees a FreeCell cell”;
  • “makes the second Draw 3 waste card accessible.”

“Moves a card” is not a strategic gain.

Test 2: What resource does it consume?

A move may occupy a cell, close an empty column, break a suited run, cover a useful destination, or advance a foundation card beyond easy retrieval. Record the cost even when the move looks productive.

Test 3: Is there an exit plan?

Temporary storage is valuable only when the stored card has a plausible next destination.

Before placing Q♣ in a FreeCell cell, identify the red King or foundation path that can release it. Before putting K♦ into an empty Klondike column, identify the Queen and lower alternating cards that justify the lane. Before breaking a Spider run, identify how the pieces will reunite.

Test 4: Does the move create a forced continuation?

Some moves are valuable because they start a reliable chain. Moving 4♣ to a foundation may release 3♥, which releases 2♠, which empties a FreeCell column. Other moves simply produce another choice without improving access.

A forced beneficial chain deserves more weight than a cosmetic rearrangement.

Test 5: What happens if the next card is unhelpful?

This is a robustness test. If a Klondike flip reveals a card you cannot use, do you still have workspace? If a Spider row lands badly, have you preserved suited segments? If a FreeCell transfer exposes a high card rather than the needed Ace, can you recover?

Good strategy does not assume the next unknown card will cooperate.

Klondike strategy

PlaySoli Klondike uses seven tableau columns, alternating-color descending builds, King-only empty columns, suited Ace-to-King foundations, and unlimited stock passes in both Draw 1 and Draw 3 SRC-001 SRC-002 SRC-003.

Prioritize hidden-card access, not every possible flip at any cost

Uncovering a face-down card is one of the clearest sources of progress. When two moves uncover cards, compare the resulting column and the resource spent.

Suppose one move uncovers a card in the seventh column but consumes your only empty column with a King. Another move uncovers a card in the fourth column while preserving that lane. The second may be stronger even though the seventh column contains more hidden cards, because it keeps a major mobility resource.

Create empty columns for specific Kings

An empty Klondike column is not generic storage. Before clearing a column, inspect which King-led sequences can fill it and what they release.

A useful King move typically does at least one of these:

  • uncovers a hidden card beneath the King;
  • transfers a long legal sequence out of a congested column;
  • positions opposite-color Queens to continue building;
  • opens a route for several stock cards.

Creating an empty column without an available King can still be valuable, but its immediate utility is limited.

Do not send every low card to the foundations automatically

A foundation move is legal progress toward the goal, but low tableau cards are also landing places. Before moving 5♥ upward, check whether 4♣ or 4♠ is trapped and needs that red 5.

A practical safety test is to compare the opposite-color foundation ranks. If both black 4s are already safely advanced or accessible, the red 5 is less likely to be needed as a tableau bridge. This is a heuristic, not a proof; the visible position controls.

Keep both colors operational

Long sequences can concentrate all useful red or black landing spots in one column. When possible, preserve more than one compatible destination for common ranks. This reduces dependence on a single buried card.

For example, if both red 9s are unavailable, a black 8 becomes difficult to move. Avoid covering the only accessible red 9 unless the move reveals something more valuable.

In Draw 1, use unlimited passes to gather information

Because PlaySoli permits unlimited passes, the first stock traversal can be observational. Note cards that are immediately playable, cards blocked by tableau requirements, and Kings that could use an empty column SRC-001 SRC-002.

Unlimited passes remove the pressure to play a mediocre waste card solely because it may never return. They do not remove the need to change the tableau; repeated passes through an unchanged position produce the same constraints.

In Draw 3, manage access order

Draw 3 strategy is partly about waste arithmetic. Only the top card is available, and removing it may expose another card in the same packet SRC-001 SRC-003.

Track three types of target:

  1. a currently exposed useful card;
  2. a useful card immediately beneath an exposed card;
  3. a useful card whose visit changes when earlier stock cards are removed.

Do not play a top card automatically. Sometimes leaving it in place preserves a more favorable alignment for a later pass; sometimes removing it is exactly what unlocks a buried King or Ace. Compare the resulting waste order.

For detailed variant decisions, see Draw 1 versus Draw 3 and the full Klondike strategy guide.

Spider strategy

Spider rewards two goals that can conflict: expose cards now and improve suit structure for later movement.

Distinguish rank progress from suit progress

Placing 8♥ on 9♣ is legal and may expose a hidden card. Placing 8♣ on 9♣ creates a same-suit connection that can move together later. The first move improves immediate access; the second improves structural mobility.

Do not follow a universal rule such as “never mix suits.” Mixed builds are often necessary, especially in two- and four-suit play. Instead ask whether the suit break is temporary and whether it unlocks enough value to justify the repair cost.

Preserve movable same-suit segments

A same-suit segment is compressed mobility. Five cards in one suited run move as one unit; the same five ranks with suit breaks may require several empty spaces to rearrange.

Before placing a card on a suited segment, check whether the new card extends the suit or caps the segment with a mismatch. A mismatched cap can temporarily immobilize everything beneath it.

Treat an empty column as a workshop

An empty Spider column lets you park a card or suited group, split a mixed sequence, reverse the order of temporary moves, and join separated suit segments.

A productive empty-column cycle often looks like this:

  1. move a same-suit group into the empty column;
  2. expose or relocate the blocking card beneath it;
  3. join that blocker to its correct rank destination;
  4. return or extend the parked group;
  5. finish with the column empty again if possible.

Filling the column permanently may be necessary, but recognize the opportunity cost.

Delay the next row until useful rearrangements are exhausted

A Spider row deal places ten new cards and can cover every carefully prepared endpoint. It is one of the most consequential actions in the game.

Before dealing:

  • expose any face-down card reachable without the row;
  • join same-suit segments that can be joined now;
  • move flexible high cards away from critical low-card destinations;
  • inspect where each new card will land;
  • fill every empty column, because PlaySoli blocks the deal otherwise SRC-001.

The last requirement creates a tactical tension: you want empty columns for work, but you must occupy them before receiving a row. Use them fully before surrendering them.

Build complete runs with an exit in mind

A completed same-suit King-to-Ace run is removed automatically SRC-001. Removal clears thirteen cards from a column and may expose cards beneath or leave the column empty, so constructing the first complete run is often a turning point. However, avoid burying the missing low cards beneath mixed stacks while concentrating only on the top half of a run.

Map the run in segments: K–10, 9–6, 5–A, for example. Determine which segment is movable and what blocks the join.

Adjust strategy by suit level

  • One suit: every rank connection is also a suit connection. Focus on exposure, empty columns, and row timing.
  • Two suits: identify which suit each segment belongs to before stacking equal ranks. Preserve long same-suit blocks.
  • Four suits: temporary disorder is unavoidable. Value empty columns more highly and make suit-breaking moves only with a clear access gain.

See Spider strategy and the suit-level comparison.

FreeCell strategy

FreeCell exposes all cards from the start, so the strongest plans can be stated before the first move. The challenge is executing them without exhausting workspace SRC-001 SRC-007.

Locate the Aces, Twos, and their blockers

Foundations begin with Aces, but reaching an Ace may require moving several high cards. Trace each low card upward through the column:

  • Which card sits directly above it?
  • Where can that blocker go?
  • Does moving the blocker expose another useful low card?
  • Will a free cell be occupied, and for how long?

Do not focus only on the deepest Ace. A shallow Ace that releases a Two can create immediate foundation flow and free a column sooner.

Keep free cells as throughput, not storage

A free cell is most valuable when cards pass through it briefly. Before using one, name the exit. Long-term occupants reduce sequence capacity and make later dependencies harder to resolve.

A useful mental label is:

  • transit card: enters a cell and leaves within the planned sequence;
  • parking card: has no immediate exit and consumes capacity.

Parking is sometimes necessary, but four parking cards usually signal a stalled plan.

Value empty columns more than single cells

An empty column can accept a card and can multiply the length of a legal supermove. It can also hold an ordered sequence through interface-assisted primitive transfers. Clearing a short column may therefore be more valuable than releasing one cell.

Do not fill the empty column merely because a high card fits. Use it to execute the dependency chain that justified creating it.

Calculate capacity before starting a transfer

An internally correct alternating-color sequence may still be too long to move. Count empty cells and empty columns before lifting the first blocker. Remember that moving into an empty column can consume one of the spaces that would otherwise support the transfer.

The dedicated supermove guide explains destination-sensitive capacity. Strategically, the lesson is simpler: workspace is a budget, and partial transfers can strand the sequence.

Advance foundations in coordinated pairs

Moving safe low cards to foundations reduces clutter. Advancing one suit far ahead of opposite-color suits can remove landing cards needed on the tableau.

Before sending a red 6 upward, inspect both black 5s. If one is trapped and the other already on a foundation, the red 6 may still be needed as the only tableau destination. Coordinated progress across colors tends to preserve flexibility.

Plan a complete liberation chain

Because all cards are visible, FreeCell rewards multi-step plans. A strong plan might be:

  1. move 6♣ to 7♦;
  2. place Q♥ temporarily in a cell;
  3. move J♠–10♥ using the newly opened column;
  4. expose A♦;
  5. advance A♦ and 2♦;
  6. move Q♥ from the cell onto K♣;
  7. finish with both the cell and column available.

The quality of the plan is not just that it reaches A♦. It restores the borrowed workspace.

See the complete FreeCell strategy guide for deeper dependency techniques.

How to review a lost deal

A replay is most useful when you identify the first structural error rather than the final moment with no moves.

Find the last healthy position

Move backward until the board still had an empty column, free cell, accessible stock target, or unbroken Spider run. The mistake often occurred before the visible lock.

Classify the decision

Was it primarily an information error, mobility error, order error, or reversibility error?

  • Information: ignored a chance to reveal or map a card.
  • Mobility: consumed workspace without adequate return.
  • Order: released cards in the wrong dependency sequence.
  • Reversibility: made a commitment before testing alternatives.

Compare only realistic alternatives

Do not judge a move using a hidden card you could not have known. In Klondike, evaluate whether the decision was robust under uncertainty. In FreeCell, where every card was visible, evaluate whether the dependency chain could have been planned more fully.

Separate deal solvability from execution

A failed attempt does not prove the deal was impossible. A solved replay does not prove every player should have found the line. Mathematical solvability, solver success, and human win rate are different concepts SRC-030. See solitaire winnability explained.

In brief

  • Judge moves by access, workspace, dependency order, and reversibility.
  • In Klondike, uncover cards while preserving useful King lanes and stock access.
  • In Draw 3, track which waste card is on top and how removals change later passes.
  • In Spider, balance immediate exposure against same-suit structure; delay row deals until current work is exhausted.
  • In FreeCell, map low-card blockers, keep cells flowing, and calculate sequence capacity before committing.
  • Temporary spaces need exit plans.
  • A legal move can be strategically weak, and no strategy guarantees that every deal is winnable.

Common strategy mistakes

Legality is only a filter. Compare what each candidate unlocks and consumes.

Maximizing immediate foundation progress

Foundation count is not the only measure of position quality. A lower foundation total with open columns and flexible tableau destinations can be stronger.

Using empty spaces as ordinary parking

An empty column has option value. Occupy it for a specific chain, not because a card has nowhere else to go.

Breaking structure without budgeting the repair

Mixed-suit Spider placements and fragmented FreeCell sequences can be necessary. Record how much workspace will be needed to restore order.

Dealing or drawing to avoid thinking

A stock action changes the problem; it does not solve the current one. Exhaust useful tableau analysis first, especially before a Spider row.

Learning only from successful deals

Easy deals can reward weak habits. Review why workspace remained available and whether a less cooperative card order would have exposed the same decision flaw.

Frequently asked questions

What is the single best general solitaire strategy?

Preserve future options. In practice, that means revealing useful information, creating or protecting workspace, and avoiding irreversible moves without a clear gain.

Should I always uncover a face-down card when possible?

Usually it is valuable, but compare the cost. If the move permanently consumes the only empty column or breaks a critical suited Spider run, another line may preserve more overall mobility.

Should Aces always go to the foundation immediately?

Aces are normally safe because no lower tableau card needs to land on them. For higher ranks, check whether opposite-color lower cards still need the card as a tableau destination.

Is an empty column always better than an empty free cell?

In FreeCell, an empty column is generally more powerful because it can support longer sequence transfers, but the exact value depends on the board. In Klondike and Spider, columns have different filling and stock rules.

Is it bad to mix suits in Spider?

Not automatically. Mixed-suit building is legal and often necessary. It becomes costly when it caps a long same-suit run or requires more empty space to repair than the position can provide.

When should I deal a new Spider row?

After current rearrangements, exposures, and suit joins are exhausted. Use empty columns before the deal, then fill them because PlaySoli does not allow a row while any column is empty SRC-001.

How do I improve at Draw 3 Klondike?

Track waste order across passes. Identify which top cards must move to expose targets beneath them, and notice how removing cards changes later packet alignment. Unlimited passes give you time to learn the cycle, but the tableau still must change.

How far ahead should I plan in FreeCell?

Plan until the borrowed workspace is restored. A sequence that reaches an Ace but leaves every cell occupied is incomplete; include the exit moves for temporary cards.

Does using undo prevent improvement?

Not necessarily. Undo can be a deliberate analysis tool when you compare branches and identify the first structural error. Repeatedly undoing without articulating the lesson provides less value.

Can strategy make every deal winnable?

No. Strategy improves decision quality, but deal solvability depends on the exact game and initial arrangement. PlaySoli does not guarantee every deal SRC-001.
