Scorpion

Form and clear four complete descending runs, one per suit, from King to Ace. All 52 cards must be in those finished runs.

One 52-card deck without jokers is dealt into seven playing columns, called the tableau, with seven cards in each. In the first four columns the uppermost three cards start face-down; all other tableau cards start face-up. An exposed card has no card covering it.

• The three remaining cards form the face-down reserve at the upper right.
• Four completed-run spaces above the columns receive finished suits automatically. There are no Ace-up foundations or waste pile.

Moving a card with its covering cards

Any face-up card can be picked up, carrying every card below it even if they are unordered. Place the chosen card on an exposed card exactly one rank higher in the same suit: a 6 of clubs goes on a 7 of clubs. You cannot leave any of its covering cards behind.

Spaces and hidden cards

Only a King or a group starting with a King can fill an empty column. Nothing goes on an Ace; ranks do not wrap. A hidden card turns face-up automatically when the cards covering it are removed.

Finished suits

A complete face-up King-to-Ace run at the exposed end of a column is removed automatically, including after the reserve deal. This is a local variation: Wikipedia describes leaving completed runs in place. Removed runs cannot be moved back by hand; Undo can restore a cleared run before winning.

Click or tap the reserve once to deal its three cards face-up onto the first three columns, one each. In this version you may deal even while another move is available or a receiving column is empty. It counts as one move. There is no further stock, recycling, or redeal.

Clearing the fourth suit wins. There is no points score here; elapsed time and moves are tracked. Moving one card or a whole group counts as one move.

There is no automatic loss detection. If the reserve is spent and no useful moves remain, try Undo, Restart current deal, or New game.

Restarting, choosing a numbered deal, or starting a new game after your first move in an unfinished deal records that attempt as a loss. Undo alone does not record a loss. Deals are shuffled without checking that they can be won.

• Move cards: drag a face-up card with your mouse or finger to carry its group. Click or tap it to use the matching-suit destination one rank higher if that card is exposed in another column. Filling an empty column with a King requires a drag.
• Undo: reverses the last action and restores the previous move count. Repeat it as needed before winning; it does not rewind elapsed time. Resume a paused game first.
• Pause: stops the timer and blocks moves until Resume.
• New game: opens a menu. Choose Random deal for a fresh layout or Restart current deal to replay the same starting cards. Both reset the move count and timer.
• Numbered deals and sharing: use Deal # to enter a deal number, or Share deal to copy its starting-layout link. Use the same game and rule settings to reproduce it.
• Saved data: your position, timer, Undo history, and statistics save in this browser when storage is available. Return and press Play to continue. Time away does not count. Clearing site data removes saves; they do not sync between devices.

• Prioritize a move that uncovers a hidden card. Those first four columns contain information you need to assemble the suits.
• Check the bottom of the group you are carrying. An unordered group may fit at its first card but bury the destination under several obstacles.
• Prepare a King group before clearing a column, since other ranks cannot use that space.
• Before dealing the reserve, use useful moves in the first three columns. The reserve will cover their current exposed cards.

Scorpion is a single-deck relative of Spider, with group movement resembling Yukon. Read more on Wikipedia.

Try Spider for groups that must already be ordered, or Yukon for unordered groups with alternating-color building and foundations.
