Spider and Scorpion are cousins in the same family of solitaire games, and at a glance they can look almost identical: both spread cards across columns, both ask you to build King-to-Ace runs, and both have that same patient, untangling feel. Yet the two play very differently, and a habit that serves you well in one can actively hurt you in the other. If you love Spider and are curious about its tactical relative, understanding Spider vs Scorpion will help you switch between them without getting caught out.

This guide lays the two games side by side, from the decks they use to the way cards move, so you know exactly what changes when you cross over. Keep both the Spider and Scorpion boards handy and compare them as we go.

The Shared Family Traits

Before the differences, it helps to see what the two games have in common, because that shared DNA is why they feel related. Both are built around columns of cards, some face down, that you gradually organise into descending sequences. In both games the ultimate prize is the complete King-to-Ace run, and in both, finishing such a run is a major step toward victory. The satisfaction of slowly converting a tangled board into ordered suits is the heart of both games.

That is roughly where the similarity ends, though. The rules that govern the decks, the building, and the movement of cards are meaningfully different, and those differences give each game its own character.

Decks: Two Versus One

The most fundamental difference is the number of cards. Spider is a two-deck game, using 104 cards dealt into ten columns, and its goal is to complete all eight suit runs. Scorpion is a single-deck game, using just 52 cards dealt into seven columns, and its goal is to complete four suit runs. The smaller deck makes Scorpion a tighter, more compact puzzle where every card matters and there is far less room to manoeuvre.

Building Rules: Any Suit Versus Strict Suit

Here the games diverge sharply, and this is the difference most likely to trip up a Spider player.

How Spider Builds

In Spider you build down by rank regardless of suit. A red 6 can legally sit on a black 7. Suit only matters when you want to move several cards at once, since only a same-suit run can be lifted as a group. This gives Spider a forgiving, flexible feel in the moment, with the suit discipline coming into play later.

How Scorpion Builds

Scorpion is strict from the start: you build down by suit only. A 6 can only go onto a 7 of the very same suit. There is no off-suit placement to fall back on, so every move must respect suit from the outset. This makes Scorpion feel more constrained and demanding, since you cannot loosely stack cards to buy time the way you can in Spider.

Moving Cards: The Big Twist

The signature feature of Scorpion is how it lets you move cards, and it is the opposite of Spider's approach. In Spider, you can only pick up a group of cards if they already form a same-suit descending run. In Scorpion, you can pick up any face-up card along with every card on top of it, no matter how jumbled that pile is, and move the whole stack onto a card one higher of the same suit.

This is a profound difference. In Scorpion you are constantly reaching into the middle of a column, grabbing a card and its messy tail, and relocating the lot to untangle the board. It rewards a different kind of thinking: instead of carefully preserving neat runs as in Spider, you plan how to unbury key cards by moving whole disordered stacks. Spider players often find this liberating once it clicks, but jarring at first.

Side-by-Side Comparison

Here is how the two games line up on the factors that matter most:

  • Decks: Spider uses two decks (104 cards); Scorpion uses one deck (52 cards).
  • Columns: Spider deals ten columns; Scorpion deals seven.
  • Goal: Spider completes eight suit runs; Scorpion completes four.
  • Building: Spider builds down by rank in any suit; Scorpion builds down strictly by suit.
  • Moving cards: Spider moves only same-suit runs together; Scorpion moves any face-up card with everything on top of it.
  • Stock: Spider deals five rows from a large stock; Scorpion has only a tiny reserve of a few cards dealt once.

Notice how nearly every mechanic differs. The family resemblance is real, but the two games ask for genuinely different skills.

Which Game Should You Play?

Choosing between them depends on what you are after. Here is a simple way to decide:

  1. Want the classic, longer game? Play Spider, with its two decks and eight suits to clear.
  2. Want a tighter, tactical puzzle? Play Scorpion, where the single deck and free movement make every choice count.
  3. New to the family? Start with Spider, ideally one-suit, to learn the core ideas gently.
  4. Comfortable with Spider and craving something fresh? Scorpion is the natural next step, using familiar goals with a bold new movement rule.
  5. Prefer the original patience feel? Try the classic single-deck games as a contrast to both.

There is no need to pick just one. Many players enjoy alternating, because switching between them keeps both feeling fresh and sharpens different tactical muscles.

Fitting Both Into the Wider Family

Spider and Scorpion sit within a larger world of solitaire games, each with its own flavour. The classic single-deck Klondike builds up onto foundations in alternating colours, a completely different structure from either spider-family game. If you enjoy tracing how these games relate, our look at Spider solitaire history puts the family in context, while how to play Spider solitaire and the full Spider solitaire rules explained ground you firmly in the main game before you branch out.

Once you play both games, the main danger is muscle memory. Habits that win in Spider can quietly sabotage you in Scorpion, and vice versa, so it pays to reset your thinking when you switch. Coming from Spider, the instinct to loosely stack a low card on any higher card will fail instantly in Scorpion, where only same-suit placements are legal, so you must plan suit from the very first move. Coming the other way, from Scorpion back to Spider, the freedom to grab any face-up card and its tail is gone; in Spider you can only lift a tidy same-suit run, so you have to protect those runs rather than relying on brute reorganisation. The good news is that both games sharpen complementary skills. Scorpion trains you to unbury key cards by moving whole messy stacks, while Spider trains patience and suit discipline across a much larger board. Alternate between them deliberately and each one will make you sharper at the other, rather than letting one game's reflexes trip up the next.

Conclusion

Spider and Scorpion share a family goal, the King-to-Ace suit run, but they get there in opposite ways. Spider uses two decks, builds in any suit, and moves only tidy same-suit runs, while Scorpion uses one deck, builds strictly by suit, and lets you move any face-up card along with everything on top of it. Learn both and you gain two distinct puzzles for the price of one skill set. Ready to compare? Open the free Scorpion board and feel the difference, then return to the two-deck Spider classic.
