Master advanced Scorpion Solitaire strategy. When to use reverse moves, column management and late-game consolidation techniques explained.
Scorpion Solitaire is one of the least understood games in the mainstream patience catalogue — widely played, rarely studied, and almost never improved at systematically. The win rate ceiling sits at approximately 65–70% of deals for players who apply careful basic play, but most experienced players plateau well below that because Scorpion's strategic structure is genuinely unusual: it combines the same-suit-only build rule of Forty Thieves with the any-face-up-card-moves rule of Yukon, and the resulting hybrid creates planning challenges that neither game individually prepares players for.
Scorpion deals all 52 cards into seven columns at the start. The leftmost four columns receive three face-down cards followed by four face-up cards. The rightmost three columns receive seven face-up cards each. Three cards are held in reserve as a single-use stock — when the game is completely stuck, these three cards are dealt one to each of the leftmost three columns. Building rule: a face-up card (and all cards resting on top of it, regardless of their sequence) may be moved to any column where the top card is the same suit and one rank higher. Win by assembling all four complete K-through-A same-suit sequences. For full rules see our complete Scorpion guide.
The two rules that create Scorpion's strategic complexity are:
1. Same-suit-only building
Every card has exactly three valid tableau destinations — the other three cards of one rank higher in the same suit — rather than the seven alternating-colour destinations available in Klondike.
2. Any-face-up-card-moves
Any card regardless of its column position can be picked up with everything above it and relocated to a valid same-suit destination.
The interaction is what makes Scorpion hard: the any-face-up-card-moves rule creates apparent freedom, but the same-suit-only constraint means most of that freedom leads to worse positions rather than better ones, because relocating a mid-column card almost always disrupts a same-suit sequence in the source column and creates a mixed-history arrangement in the destination column that is harder to unravel than the original position was.
A reverse move in Scorpion is any use of the any-face-up-card-moves rule to pick up a card that is not at the top of its column — a card that has other face-up cards resting on it — and relocate it with its pile to a valid same-suit destination. Reverse moves are the defining tactical feature of Scorpion and the most misused. Understanding when a reverse move is the correct play and when it is a trap is the central analytical skill of advanced Scorpion play.
A reverse move is correct when it simultaneously accomplishes at least two of three objectives.
1. Uncovering a face-down card
If the card being picked up is the deepest face-up card in a column containing face-down cards, relocating it with its pile reveals a face-down card.
2. Completing or extending a same-suit sequence
If the destination column contains the matching same-suit card at rank one higher and the relocated pile is internally same-suit from that connection point, the reverse move creates or extends a genuine sequence.
3. Freeing a column top that was previously locked
If the top card of the source column after the reverse move has a valid same-suit destination that it did not have before, the reverse move has increased that column's mobility.
A reverse move that accomplishes only one of these objectives usually costs more in source-column disruption than it gains.
A reverse move that accomplishes two or three is almost always correct regardless of how messy the resulting arrangement looks.
Never use a reverse move to create visual order without functional improvement. The most common misuse of Scorpion reverse moves is picking up a mid-column card and relocating it because the resulting arrangement looks cleaner or more sequential, without any of the three functional objectives being met. A column that looks more ordered but has the same face-down card coverage, the same suit-sequence continuity, and the same column-top accessibility as before is a column where a move budget has been spent for zero game-progress return. Before every reverse move, name which of the three objectives it accomplishes. If the answer is none — if the improvement is purely visual — do not make the move.
Evaluate the source column disruption cost before every reverse move. When a mid-column card is picked up with its pile, the card immediately below it in the source column becomes the new accessible top. If that newly exposed card has a valid same-suit destination or is needed for a sequence completion, the disruption cost is low — the source column is not made worse by the exposure. If the newly exposed card is a suit that is completely blocked or a rank with no accessible same-suit destination, the disruption cost is high — the source column has been made less functional while the destination column has gained a pile of uncertain sequence quality. Calculate both the objective value of the reverse move and the disruption cost of the source exposure before committing.
The high-value reverse move: uncovering a face-down card through a same-suit sequence extension. The highest-value reverse move pattern in Scorpion is one where a mid-column card is picked up with its pile, moved to a same-suit destination that extends a genuine sequence, and the resulting source-column exposure reveals a face-down card. This triple payoff — sequence extension, face-down reveal, and pile relocation — is relatively rare but easy to miss because it requires looking not just at the card being moved but at the card beneath it and the suit-sequence state of potential destinations simultaneously. Developing the habit of checking for this pattern specifically — scanning mid-column cards for the combination of same-suit destination available and face-down card directly below — is one of the highest-return analytical habits in advanced Scorpion play.
Reserve the stock for genuine impasses, not uncomfortable positions. Scorpion's three-card reserve stock is a one-time resource that adds one card to each of the three leftmost columns. Because the stock is finite and non-renewable, using it in response to a position that merely feels stuck — rather than one that is genuinely unplayable — wastes it on a situation that careful reverse-move analysis would have resolved. Before using the stock, verify that no reverse move exists that accomplishes any of the three functional objectives, that all direct same-suit building moves have been exhausted, and that all face-down cards that can be uncovered have been uncovered. If these three conditions hold, the stock is correct. If any of them does not hold, continue analysing before dealing the reserve.
Scorpion's seven columns provide a more constrained working surface than Spider's ten or FreeCell's eight. With same-suit-only building and only seven columns, the proportion of available moves at any given point is lower than in most other patience games, and the proportion of moves that create dead positions is correspondingly higher. Seven-column management in Scorpion is therefore more about preventing column lock-up than about optimising sequences — maintaining the minimum column functionality needed to keep the game playable is a higher priority than building the most advanced sequences.
Classify each column's suit composition at the start of each major decision phase. A column in Scorpion falls into one of four composition states: suit-pure (all face-up cards are the same suit, in full or partial sequence), suit-dominant (the majority of face-up cards are one suit with one or two intruders), suit-mixed (two or more suits roughly equally represented), and suit-locked (the column top has no valid same-suit destination anywhere in the tableau). Suit-locked columns are the equivalent of rigid columns in Spider or dead columns in Forty Thieves — they are active obstacles rather than passive occupants. Count suit-locked column tops at the start of each phase; more than two simultaneously is a warning signal that the tableau is approaching an unwinnable configuration.
Prevent suit intruders before they accumulate. The path from a suit-dominant column to a suit-mixed column typically runs through a single reverse move that placed a card of the wrong suit onto a column whose suit composition was already close to pure. Suit intruders — cards of a different suit embedded within an otherwise same-suit sequence — are much harder to remove than to prevent, because removing them requires a reverse move that is only valid if a same-suit destination exists at the correct rank, which may not exist for several more moves. The discipline: before any reverse move that places a pile onto a destination column, check the suit of the pile's bottom card and the suit of the destination column's existing composition. If they differ, the reverse move is introducing a suit intruder. This is acceptable when the functional objectives justify it; it is not acceptable when the move is being made primarily for visual tidiness.
Prioritise uncovering face-down cards in the order that maximises suit-sequence options. Scorpion's four leftmost columns each contain three face-down cards at the start. The order in which these twelve face-down cards are uncovered is not arbitrary — the suit of each revealed card determines which same-suit sequence extensions become available, which reverse moves become valid, and which column compositions shift from mixed toward pure. Rather than simply uncovering face-down cards in the order of shallowest-to-deepest accessibility, evaluate which uncovering would produce the most useful suit revelation: if one column's face-down card is likely (based on which cards are visible) to be a suit that the current tableau needs for a sequence completion, prioritise that column's uncovering above a shallower column whose suit is already well-represented in the face-up cards.
Scorpion's late game — the phase when all face-down cards have been revealed and the stock has been used or is being held in reserve — is structurally different from every earlier phase of the game. In the early and mid-game, the primary goal is uncovering face-down cards to expand available options. In the late game, all options are already visible and the goal shifts entirely to consolidation: assembling the four partial same-suit sequences scattered across seven columns into four complete K-through-A runs, each on a single column, in the correct order for foundation play.
Audit the four suits' consolidation requirements before beginning late-game play. When the last face-down card is revealed, stop and spend twenty to thirty seconds auditing all four suits. For each suit, identify: how many cards are accessible (on column tops or in movable piles), how many are buried beneath cards of other suits, and what sequence of moves would be required to consolidate the suit's cards into a single column. This audit replaces reactive late-game play with a targeted consolidation plan and is the single most important habit change at the transition from mid-game to late-game Scorpion.
Consolidate the most advanced suit first. The suit with the most cards already in sequence — closest to a complete K-through-A run — is the correct consolidation target because it requires the fewest moves to complete. Completing one suit's consolidation first reduces the total card count by thirteen, opens a column position, and critically simplifies the remaining consolidation work by removing that suit's cards from the mixed-suit pools of the remaining columns. Players who try to advance all four suits simultaneously in the Scorpion late game consistently find that the column flexibility needed to complete the final consolidation moves does not exist, because all seven columns remain occupied by partial sequences of all four suits. Completing one suit fully before substantially advancing the others is almost always the more efficient path.
Use empty columns as consolidation pivots, not sequence anchors. If an empty column appears during late-game consolidation — from a suit being fully assembled on one column — its highest-value use is as a temporary pivot to enable a consolidation move that would otherwise be blocked. The pattern: suit A's 7 needs to reach suit A's 8, but a suit B card is blocking the 8's column top. Use the empty column to temporarily receive the suit B card, execute the suit A consolidation move, then relocate the suit B card to its correct destination. This pivot pattern — empty column receives block, consolidation move executes, block relocates — resolves the majority of late-game blockages in Scorpion. Using the empty column to start a new sequence instead immediately eliminates its pivot function for the rest of the game.
Plan consolidation sequences to avoid suit-lock in the penultimate phase. The most common late-game Scorpion failure is a consolidation sequence that produces correct suit groupings for three suits but leaves the fourth suit's cards distributed across columns in an arrangement where the final consolidation moves are all blocked by the newly completed suits' sequences. This is prevented by planning consolidation in reverse: before beginning the consolidation sequence for suit A, identify where suit D's final consolidation cards will need to go and confirm that completing suit A does not place any card in a column position that will block suit D's final moves. A five-move forward trace of suit D's consolidation requirements before beginning suit A's consolidation is a low-cost investment that prevents the most common late-game Scorpion loss.
The suit-order dependency trap. In Scorpion's very late game — three or fewer cards per suit remaining — suit-order dependencies frequently appear: suit A's last card cannot move until suit B's card moves, but suit B's card cannot move until suit C's card moves, which requires suit A's penultimate card to have already moved. These circular dependencies are not always resolvable; when they are, the resolution requires identifying the correct sequencing of suit moves across all four suits simultaneously rather than completing one suit at a time. When a circular dependency appears, trace all four suits' remaining moves together as a single sequence and identify whether a valid ordering exists. If yes, execute it precisely. If no valid ordering exists, the position is unwinnable — but the circular dependency test confirms this quickly rather than leaving it to be discovered through repeated failed attempts.
Track the same-suit destination availability for every column top simultaneously. At any given point in Scorpion, some column tops have valid same-suit destinations in the current tableau and some do not. The ratio of accessible-to-locked column tops is the real-time flexibility metric of the game: a tableau where five of seven column tops have valid destinations is in much better shape than one where only two do. Make this ratio explicit by quickly scanning all seven column tops against the current tableau after every move. When the ratio falls to three or fewer accessible tops, treat it as a signal to prioritise unlocking moves — reverse moves, stock use, or sequence completions that expose new accessible tops — over consolidation or sequence-building moves that do not improve accessibility.
Identify and plan for the suit with the most buried cards before the stock is used. Before dealing the three-card reserve, identify which suit has the most cards buried beneath face-up cards of other suits. The three stock cards will land on the leftmost three columns regardless of their suits; the resulting positions may make the buried suit's excavation easier or harder depending on what the stock cards are. Since the stock suits are unknown in advance, the best pre-stock preparation is to maximise the face-up accessibility of the most-buried suit before dealing — any reverse move that brings a buried-suit card closer to the surface before the stock lands is more valuable than a reverse move that tidies a suit that already has good surface accessibility.
Apply the two-objective test before every reverse move in the late game. In the early and mid-game, a reverse move that accomplishes one of the three functional objectives (uncover, sequence, unlock) is sometimes acceptable because the tableau has enough flexibility to absorb the source-column disruption. In the late game, the tableau's flexibility is nearly exhausted and source-column disruption costs are much higher. Apply the two-objective standard — a late-game reverse move should accomplish at least two of the three functional objectives — as a filter before any reverse move in the final third of the game. This stricter standard prevents the late-game erosion of positional flexibility that causes otherwise-winning positions to lock in the final consolidation phase.
A reverse move — picking up a mid-column face-up card with all cards above it and moving it to a same-suit destination — is correct when it accomplishes at least two of three functional objectives: uncovering a face-down card, completing or extending a same-suit sequence, or freeing a locked column top. The highest-value reverse move simultaneously reveals a face-down card and extends a same-suit sequence in the destination column — a combination that is easy to miss because it requires checking the card beneath the moved card and the suit-sequence state of the destination column at the same time. Reverse moves that accomplish only visual tidiness without any functional improvement are almost always positional degradations: they consume move budget and introduce suit intruders into destination columns without advancing game progress. In the late game, raise the threshold to two objectives minimum before any reverse move is executed. Play our free Scorpion Solitaire game and apply the two-objective test from your next hand.
Four disciplines combine to produce effective late-game consolidation. First, audit all four suits' consolidation requirements the moment the last face-down card is revealed — identifying how many cards of each suit are accessible versus buried before beginning any consolidation move. Second, consolidate the most advanced suit fully before substantially advancing others — completing one suit reduces the card count, opens a column, and simplifies the remaining work more than partial advancement of all four suits simultaneously. Third, use any empty column that appears as a consolidation pivot — temporary block receiver, not sequence starter — to resolve the blocked-card situations that late-game consolidation consistently produces. Fourth, before beginning any suit's consolidation sequence, trace the remaining consolidation requirements of the other three suits to ensure the completed suit does not create blocking positions for them.
