Spider Solitaire is one of the most strategically demanding and satisfying card games available online. Where Klondike challenges you to build four foundation piles using cards drawn from a partially hidden stock, Spider puts ten columns of cards in front of you and asks you to build complete King-to-Ace sequences entirely within the tableau. Everything is on the table — the challenge is finding the sequence of moves that untangles it.
The game uses two standard 52-card decks shuffled together — 104 cards in total — dealt into ten tableau columns. Four columns receive six cards each and six columns receive five cards each. Only the top card of each column is face-up at the start; the rest are face-down and are revealed as the cards above them are moved. Six additional stock deals are available during the game: when you choose to, clicking the stock deals one new card face-up onto each of the ten columns simultaneously.
The goal is to build complete sequences from King down to Ace within a single suit in any tableau column. When a complete same-suit sequence of thirteen cards — King through Ace — is assembled in a single column, it is automatically removed to the foundation. Build all eight such sequences from both decks and you win. The game ends when all 104 cards have been cleared from the board.
Cards in the tableau can be placed on any card of the next rank up, regardless of suit — a 7 of hearts can go on an 8 of any suit. However, only same-suit sequences can be moved as a unit. A mixed-suit sequence can be built in a column and used for temporary organisation, but it cannot be moved as a group and cannot be removed to the foundation. This distinction between what can be built and what can be moved is the central strategic tension of Spider.
Spider's rules are straightforward to learn but their strategic implications run deep. Here is the complete ruleset.
The Tableau: Ten columns of cards. Four columns start with six cards (one face-up, five face-down) and six columns start with five cards (one face-up, four face-down). All play happens within the tableau — there are no separate foundation piles to build toward during the game.
Moving Cards: Any face-up card can be moved onto any face-up card of the next rank up, regardless of suit. A 9 of clubs can go on a 10 of hearts. A Queen of diamonds can go on a King of spades. Suit is irrelevant for basic placement.
Moving Sequences: Only a sequence of face-up cards that are consecutive in rank AND all the same suit can be moved as a unit. A same-suit run of black 8, black 7, black 6 can be picked up and moved together. A mixed-suit run of red 8, black 7, red 6 is frozen in place — individual cards within it may be moved one at a time, but not the sequence as a group.
Empty Columns: When all cards are cleared from a column, any card or valid moveable sequence can be placed there. Empty columns are rare and extremely valuable — they function as temporary staging spaces for complex reorganisation moves.
The Stock: Six additional deals are available throughout the game. Each deal places one face-up card on each of the ten columns simultaneously. You cannot use the stock if any column is empty — all ten columns must have at least one card before a stock deal is triggered.
Completing Sequences: When a complete King-to-Ace sequence of a single suit is assembled in any column, it is automatically removed from the board. Eight such completions win the game.
Suit Modes: Spider is played in three difficulty modes. In 1-Suit mode, all 104 cards use a single suit (typically spades). In 2-Suit mode, two suits are used. In 4-Suit mode, all four suits are present. The mode dramatically affects strategy and win rate.
Spider requires a different strategic orientation from Klondike. Because the entire board is visible and all play happens within the tableau, the game rewards long-range planning over reactive move-by-move decision-making. The players who win most consistently think in terms of column organisation, suit purity, and sequence mobility rather than individual card placements.
Prioritise same-suit sequence building from the first move. This is the most important strategic principle in Spider. Every mixed-suit sequence you build is a sequence that cannot be moved as a unit and cannot contribute to a foundation completion. Every same-suit sequence you build is freely moveable and one step closer to a completion. Before placing a card on another, ask: does this maintain suit purity in this column, or does it create a mixed sequence? When a same-suit extension is available, always take it over a mixed one.
Uncover face-down cards as efficiently as possible. Face-down cards are the primary constraint on planning in Spider. Focus early moves on columns with the most face-down cards — getting them exposed quickly opens up the board and reveals what reorganisation is possible. When choosing between two moves that both make progress, prefer the one that uncovers a face-down card in the deeper column.
Protect and create empty columns. An empty column in Spider is as valuable as several free cells in FreeCell — it enables moves that would otherwise be impossible. To create one, focus uncovering effort on the shortest column (fewest total cards) and systematically move its face-up cards elsewhere. Once you have an empty column, use it purposefully as a stepping stone for a specific reorganisation sequence, not as a permanent home for the first card that needs somewhere to go.
Delay stock deals as long as possible. Each stock deal adds a new card to every column at once, introducing complexity across the entire board simultaneously. Triggering a stock deal when columns are disorganised makes recovery significantly harder. Before using the stock, aim to have as many columns as possible in clean same-suit sequences — the new cards land on an organised board rather than a chaotic one.
Think in sequence units, not individual cards. The moves that matter most in Spider are those that relocate entire sequences, not individual cards. A sequence of seven same-suit cards moved as a unit in one action is dramatically more efficient than moving those seven cards one at a time. Planning around sequence-level moves produces far more efficient play than planning move by move.
Spider Solitaire's three suit modes are not simply the same game at different difficulty settings — they are strategically distinct games that reward different emphases and challenge different skills.
1-Suit Spider: All 104 cards use a single suit, typically spades. Because every card is the same suit, suit purity is automatic — any sequence you build is a valid same-suit sequence by definition. There is no colour or suit tracking required; all strategic attention goes to rank ordering, column management, and empty column creation. Win rates with careful play reach 60–70%, making 1-Suit Spider the right starting point for players new to the game.
2-Suit Spider: Two suits are in play — typically spades and hearts. Mixed-suit sequences are now a genuine strategic hazard: a column that alternates between spades and hearts builds validly in terms of rank but cannot be moved as a unit or completed to the foundation. Recognising when a sequence you're building will become mixed — and deciding whether to accept that constraint or find a same-suit alternative — is the primary skill 2-Suit Spider develops. Win rates with careful play sit around 40–50%.
4-Suit Spider: All four suits are present in the 104-card deck. Maintaining same-suit column discipline while managing ten columns simultaneously is the defining challenge. Mixed-suit sequences accumulate quickly because same-suit extension is often unavailable, and each mixed sequence added narrows future options. Win rates with careful play sit around 30–40%. 4-Suit Spider is the hardest mainstream solitaire variant and rewards the deepest strategic planning.
The progression recommendation: start with 1-Suit until your win rate consistently exceeds 60%, move to 2-Suit, and attempt 4-Suit only once you're winning 2-Suit games at a 40%+ rate. Jumping directly to 4-Suit without the intermediate habits typically produces frustrating results.
Check suit before every placement. Before placing any card on another, check whether the placement maintains suit purity in that column. One thoughtless mixed-suit placement early in a game can create a frozen sequence that costs fifteen moves to resolve. The check takes one second and prevents one of the most common sources of avoidable difficulty in Spider.
Use empty columns as bridges, not storage. The most efficient use of an empty column is as a temporary bridge in a multi-step sequence relocation — park one end of a sequence there, reorganise the cards beneath its original position, then move it to its final destination. Using an empty column as permanent storage for a card with nowhere useful to go is the most common way players waste their most valuable resource.
Count face-down cards per column before planning. Before deciding where to focus your uncovering effort, count how many face-down cards each column has. The column with the most is your primary target — clearing it first gives you the most new information and the most new options.
Don't trigger a stock deal with empty columns present. The stock deal rules require all ten columns to have at least one card. If you have empty columns available when thinking about using the stock, the empty columns are more valuable than the stock deal — use them first to complete the reorganisation that made them necessary.
Build toward the shortest column for clearing. When planning to create an empty column, choose the shortest column as your target — the one with the fewest total cards. Clearing a four-card column takes fewer moves than clearing a seven-card column, and the empty column you create is equally useful either way.
Enable unlimited undo and use it speculatively. The highest-value use of undo in Spider is speculative comparison at decision points: when two moves both seem reasonable, test the first, evaluate the board, undo, test the second, compare, then commit. This is especially important in 4-Suit Spider where the consequences of a suit-mixing decision can take ten or fifteen moves to fully manifest.
Spider Solitaire win rates vary significantly by suit mode and play quality.
1-Suit Spider: Casual play produces win rates of 40–50%. Consistent strategic play — same-suit sequencing priority, efficient face-down uncovering, disciplined empty column use — raises this to 60–70%. 1-Suit is achievable at high win rates with relatively modest strategic effort, which makes it an excellent confidence-building variant before advancing to multi-suit play.
2-Suit Spider: Casual play produces win rates of 20–35%. With careful suit-tracking and the strategic habits above, win rates reach 40–50%. The jump from 1-Suit to 2-Suit win rates is significant and reflects the genuine strategic complexity that two-suit management introduces — a 40% win rate in 2-Suit represents strong play.
4-Suit Spider: Casual play produces win rates of 10–20%. With expert-level planning — four-to-five-move ahead thinking, aggressive empty column creation, systematic suit discipline from move one — win rates can reach 30–40%. A 35% win rate with careful play is a genuine achievement.
The practical improvement path: build same-suit sequencing instincts in 1-Suit, transfer them to 2-Suit with the addition of conscious suit tracking, and apply both to 4-Suit with deeper pre-move planning. Win rates improve in each mode as the habits from the previous mode become automatic.
The three modes use different numbers of suits in the 104-card deck. In 1-Suit, all cards are the same suit, so suit purity is automatic and strategy focuses entirely on column management. In 2-Suit, mixed-suit sequences become the central strategic challenge. In 4-Suit, all four suits are present, making same-suit sequence maintenance much harder. Win rates drop with each step: roughly 60–70% for 1-Suit, 40–50% for 2-Suit, and 30–40% for 4-Suit with consistent strategic play.
No. Only sequences that are consecutive in rank AND all the same suit can be moved as a unit. A mixed-suit sequence — for example, a black 8 followed by a red 7 — is frozen in place. Individual cards within it can be moved one at a time, but the sequence cannot be relocated as a group. This rule is why same-suit building is so important: mixed sequences are frozen assets that require additional moves to break apart.
As late as possible. Each stock deal adds one card to every column simultaneously, introducing complexity to all ten columns at once. The right time is when the tableau is as organised as it can be made without new cards — same-suit sequences consolidated, face-down cards fully exposed, empty columns used productively. A stock deal landing on an organised board gives you the best chance of integrating the new cards cleanly.
When a complete King-to-Ace sequence of a single suit is assembled in one column, it is automatically removed from the board and placed on the foundation. This frees up space in that column — potentially creating a full empty column if no cards remain. Completing a sequence is the highest-value single event in Spider; planning moves around accelerating the first completion is often the most efficient path to winning.
Yes, generally. Klondike Turn 1 win rates reach 40–45% with careful strategic play. Spider 1-Suit is comparable in difficulty. Spider 2-Suit is significantly harder than Klondike at equivalent skill levels, and Spider 4-Suit is widely considered the hardest mainstream solitaire variant — with win rates of 30–40% representing genuinely strong play.
When the tableau appears stuck, follow this protocol. First, rescan every column for any same-suit extension opportunity that may have been missed. Second, check whether any mixed-suit sequence can be broken apart by moving individual cards to create a more useful arrangement. Third, if an empty column can be created by fully clearing the shortest column, do so before touching the stock. Only trigger a stock deal after all three steps are exhausted.
