Spider Solitaire is a two-deck, ten-column solitaire game in which the objective is to build complete suit sequences from King down to Ace within the tableau columns, removing each completed sequence from the board until all 104 cards have been cleared. Unlike Klondike, where the win condition is placing cards onto four foundation piles outside the tableau, Spider's win condition is constructed entirely within the tableau itself — and that structural difference is why forward planning is so much more important in Spider than in any other mainstream variant.

Unlike Klondike, where the win condition is placing cards onto four foundation piles outside the tableau, Spider's win condition is constructed entirely within the tableau itself — and that structural difference is why forward planning is so much more important in Spider than in any other mainstream variant.
In Klondike, a foundation placement is always permanent progress: the card is off the board and cannot interfere with later play. In Spider, a sequence build is only progress if it advances toward completion; a build that moves cards further from their suit partners creates structural problems that accumulate over time. This is the defining challenge of Spider strategy: every move that looks like progress may simultaneously be creating an obstacle several moves later, and distinguishing genuine progress from pseudo-progress requires planning two, three, or four moves ahead at every decision point. Players who play Spider reactively — moving cards whenever a legal build is available — find that the board gradually becomes intractable: sequences are long but mixed-suit, columns are dense, and the stock deals that are supposed to refresh the position instead bury the partial sequences under new cards.
This article covers the complete forward planning framework for Spider Solitaire — how to read board state, which planning horizons apply to which decision types, what the structural obstacles to forward planning are, and how to develop the specific lookahead habits that separate 30–40% win rate casual play from 60–70% win rate strategic play in Spider 1-Suit. For related planning concepts that apply across all variants, see our guides on hidden moves and stock timing.
Spider is played with two standard 52-card decks shuffled together (104 cards total). The initial deal places 54 cards across ten tableau columns: four columns receive six cards each and six columns receive five cards each, with only the top card of each column face-up. The remaining 50 cards form five stock deal-piles of 10 cards each. Legal tableau moves: a face-up card or a sequence of face-up cards in consecutive descending rank may be moved onto any column whose top card is one rank higher. In Spider 1-Suit, any colour card may be placed on any higher-rank card of any suit. In Spider 2-Suit, cards can be moved onto cards of the same colour. In Spider 4-Suit, cards must match the exact same suit. A complete sequence (King through Ace of one suit, or of matching cards in the variant's rules) is automatically removed from the board. A stock deal requires all ten columns to contain at least one card and places one new card face-up on each column.
The critical difference between Spider 1-Suit, 2-Suit, and 4-Suit is not merely difficulty — it is planning depth. In 1-Suit, any card can be placed on any higher-rank card, which means a seven can always find a receiving eight somewhere in the tableau. The planning challenge is managing sequence purity — keeping same-suit sequences together so they can eventually be completed — while using cross-suit builds as temporary staging. In 2-Suit and 4-Suit, the same-colour or same-suit constraint means that finding a valid receiving card becomes harder as the game progresses and columns become mixed, requiring deeper planning to identify the sequences of moves that maintain both build validity and suit purity simultaneously.
Planning Horizon 1: The immediate tableau scan (1–2 moves). The first planning layer is the immediate scan: what legal moves are available, and which of them are suit-pure versus mixed? In Spider 1-Suit, every legal build is available regardless of suit, so the scan is entirely about which available builds are same-suit (advancing toward a completable sequence) versus mixed-suit (creating structural problems). Same-suit builds should be strongly preferred over mixed-suit builds at the same planning depth. This single habit — same-suit before mixed-suit — is the highest-leverage planning improvement available at the beginner level and is responsible for a large portion of the win rate improvement from casual to developing Spider play.
Planning Horizon 2: The sequence progression chain (3–5 moves). The second planning layer identifies sequences of three to five moves that together advance a partial suit sequence toward completion without creating blocking configurations elsewhere. A typical sequence progression chain in Spider 1-Suit: move the 6 of spades onto the 7 of spades (same-suit build), which exposes the 8 of spades below it, which can receive the 7 of hearts from another column (mixed build to free the column), which exposes a face-down card in the source column. The chain has a same-suit build, a mixed build, and a face-down card reveal — each step is individually modest, but the chain produces both sequence progress and information gain. Recognising and executing these chains requires looking three to five moves ahead and identifying which first move initiates the most valuable chain, not which first move is immediately most satisfying.
Planning Horizon 3: The empty column strategy (5–8 moves). Empty columns are Spider's most powerful positional resource, and managing them requires planning five to eight moves ahead. An empty column in Spider can: stage a sequence while its source column is reorganised; temporarily hold a blocking card that needs to move before a useful sequence can be accessed; serve as the pivot point for a cross-column sequence transfer that consolidates two partial sequences into one; or be filled with a King sequence to initiate a new suit completion attempt. Each of these uses has a different optimal timing and a different cost in subsequent flexibility. Planning at the 5–8 move horizon is specifically about deciding which empty column use is most valuable given the current board state — and resisting the instinct to fill the empty column immediately with whatever is available.
Planning Horizon 4: The completion sequencing plan (full visible depth). The fourth planning layer is the highest-level plan: which suit is most advanced toward completion, and what sequence of moves across the next eight to twelve turns will complete it? Completing a suit sequence removes 13 cards from the board, frees the column the sequence was occupying, and generates significant positional space for all subsequent planning. The optimal completion sequencing plan identifies the suit closest to completion, maps the remaining cards needed in that suit, identifies where each needed card currently is in the tableau or stock, and constructs the sequence of intermediate moves that will bring those cards into position. This planning layer is where the difference between 40% and 60%+ win rates in Spider 2-Suit and 4-Suit is primarily located — players who have a completion plan win significantly more often than players who build reactively toward whichever partial sequence happens to be immediately accessible.
Tip 1: Never make a mixed-suit build without a specific reason. In Spider 1-Suit and 2-Suit, mixed-suit builds are legal and sometimes necessary. The strategic rule is that each mixed-suit build should have a specific justification: it stages a card to enable a subsequent same-suit build; it frees a column position that will then receive a card completing a suit sequence; it temporarily holds a blocking card while a face-down card is uncovered. Mixed-suit builds without specific justifications — made because the build is available and looks productive — accumulate into unmoveable mixed sequences that eventually lock up significant portions of the tableau. The discipline of demanding a reason before each mixed-suit build is the most differentiating habit between intermediate and advanced Spider players.
Tip 2: Count how many cards each suit still needs before deciding which to pursue. At any mid-game position, a quick mental count of each suit's completion status — how many cards of each suit are already in sequence, how many are scattered, and where the missing cards are — provides the information needed to choose which suit to prioritise in the next planning cycle. The suit with the fewest missing cards and the most accessible missing cards is the completion target; other suits are managed to avoid blocking the target suit's completion sequence. This completion priority habit is directly analogous to the foundation balance principle in Klondike but operates within the tableau rather than across foundations.
Tip 3: Preserve empty columns for specific high-value uses. The temptation to fill an empty column immediately with a King is Spider's equivalent of Klondike's instinct to fill an empty column with the first available King. The strategic response is to identify the specific highest-value use of each empty column before filling it. In Spider 2-Suit and 4-Suit specifically, empty columns are scarce enough that filling them without a specific plan often costs a completion opportunity that would have used the column as a staging pivot. The empty column should remain open until the specific three to five move sequence that uses it is identified and ready to execute.
Tip 4: Delay stock deals until the tableau is genuinely stuck. As described in our stock timing guide, Spider deals should be triggered only when the tableau has been fully squeezed of productive moves. In Spider specifically, there is an additional planning consideration before each deal: does the current board contain any non-obvious hidden moves — preparatory unblocks, cross-column routes, suit-purity preservation moves — that would be covered and potentially reversed by the deal? A deal triggered one move too early buries an accessible partial sequence under a new card and may interrupt a completion chain that was two or three moves from a suit removal. Spending thirty seconds scanning for non-obvious moves before each deal is one of the highest-return planning investments available in Spider.
Tip 5: Plan the endgame from the middle of the board. In Spider 2-Suit and 4-Suit, the endgame — the last two or three suit completions — requires the most precise planning. By the mid-game, when three or four suits have been completed and removed, the remaining cards are distributed across fewer columns with higher suit concentration. The moves that will complete the remaining suits need to be identified at the mid-game stage, not improvised in the endgame, because mid-game decisions about which columns to consolidate, which partial sequences to protect, and which empty columns to preserve determine whether the endgame has a clear winning path or a tangled blocked position. Expert Spider players note that games are won or lost at the mid-game planning stage, not in the endgame itself.
Prioritising sequence length over sequence purity. The most common Spider mistake at the intermediate level is building the longest available sequence rather than the most suit-pure available sequence. A mixed sequence of eight cards looks impressive and provides a long build chain, but it cannot be completed and cannot be moved as a unit — it occupies column space without contributing to the win condition. A same-suit sequence of three cards is less visually impressive but directly advances a completion candidate. Players who prioritise length over purity consistently find their mid-game boards locked by unmoveable mixed sequences occupying most of the tableau columns.
Triggering deals to escape complicated positions. Spider deals are irreversible and add complexity to an already complex board. Triggering a deal when the tableau is complicated but not genuinely stuck typically makes the position harder, not easier — the new cards add to the complexity without resolving the structural problem that made the position seem stuck. The structural problem is almost always an unmoveable mixed sequence that needs to be reorganised through a non-obvious move sequence rather than covered by new cards. For the complete taxonomy of non-obvious moves that resolve these positions, see our hidden moves guide.
Treating Spider 1-Suit habits as directly transferable to 2-Suit and 4-Suit. Spider 1-Suit permits any colour on any higher rank, which creates a forgiving environment where mixed-suit builds have low cost — they can always be moved to another column of the appropriate rank. Spider 2-Suit and 4-Suit's colour and suit constraints make mixed builds structurally costly in ways that do not exist in 1-Suit. Players transitioning from 1-Suit to 2-Suit often discover that the mixed-build habits they developed in 1-Suit produce rapidly deteriorating board states in 2-Suit, because the same mixed sequences that were easily reshuffled in 1-Suit become immoveable blocks in 2-Suit. The transition requires explicitly recalibrating the cost of each mixed build from negligible (1-Suit) to significant (2-Suit) to severe (4-Suit).
Spider 1-Suit, 2-Suit, and 4-Suit are all available free at onlinesolitairefree.com with unlimited undo, making the full speculative comparison practice from our strategy simulator framework available from the first session. For players developing the planning habits described in this article, the recommended progression is: Spider 1-Suit first (builds same-suit versus mixed-suit discrimination without colour constraints), then Spider 2-Suit (adds colour constraints, requires more precise suit-purity management), then Spider 4-Suit (maximum suit constraint, requires full completion sequencing planning from the opening).
FreeCell is the most useful parallel practice game for Spider strategy development — its complete information and full-deck deal make the forward planning habits (completion sequencing, empty cell management, suit tracking) directly applicable to Spider's challenges, while its higher win rate provides more successful practice outcomes per session. Pyramid Solitaire develops pair-evaluation and deal-timing habits in a different structural context, offering useful variety in planning challenges. The complete difficulty progression across all variants is available in our difficulty calculator.

The most impactful single habit for Spider Solitaire is the same-suit-before-mixed-suit preference: at every decision point, choose the same-suit build over the mixed-suit build whenever both are available. This habit alone produces the largest win rate improvement from casual to developing Spider play, because it directly addresses the root cause of most Spider losses — the accumulation of unmoveable mixed sequences that gradually lock up the tableau. The second most impactful habit is the empty column preservation rule: identify a specific three to five move use for an empty column before filling it, rather than filling it immediately with the first available King. Together, these two habits shift the board state trajectory from progressive deterioration to genuine sequence advancement, which is the qualitative difference between losing most Spider games and winning most of them.
Spider 1-Suit has the highest win rate (approximately 60–70% at strategic level) because its any-card-on-any-higher-rank rule provides the most flexible build options, making it easier to maintain suit purity while still having valid build targets available throughout the game. The complete information (all face-up cards in modern implementations) combined with 1-Suit's build flexibility gives a skilled player considerable control over sequence development. Spider 2-Suit drops to approximately 40–50% win rate at strategic play because the colour constraint significantly reduces valid build options, making suit purity maintenance harder. Spider 4-Suit drops further to 30–40% because the exact-suit constraint is highly restrictive and many positions become blocked when the suit-matched receiving card is inaccessible.
No. Spider Solitaire, like all mainstream solitaire variants, has a proportion of mathematically unwinnable deals — specific starting arrangements from which no legal sequence of moves leads to all suit sequences completed. In Spider 1-Suit, this proportion is relatively small; the flexible build rules mean that most deals have at least one winning path accessible to a sufficiently skilled planner. In Spider 4-Suit, the proportion is larger; the strict suit constraints mean that some starting arrangements produce unavoidable structural blockages regardless of planning quality. The forward planning framework in this article improves win rates by converting previously lost winnable deals into wins — not by making unwinnable deals winnable. Even with perfect planning, the mathematical floor of unwinnable deals in each variant remains a hard constraint on achievable win rates.
