Meet Scorpion
The following details apply here. Scorpion on unclesc.com uses one 52-card deck with four suits. The tableau has seven columns. Moves build down in the same suit rather than allowing cross-suit destinations. Four complete King-to-Ace runs clear the game.
The initial seven columns
Keep these points in mind. Each opening column contains seven cards for a total of 49 tableau cards. The first three cards in each of the first four columns are face down. Three cards remain in the stock. All cards in the last three columns are face up.
Check rank and suit together
Here are the details for this mode. A King cannot land on another card because no higher rank exists. A seven of hearts can land on an exposed eight of hearts. A seven of hearts cannot land on an eight of spades. A moved group's leading card must land on a card exactly one rank higher in the same suit.
Order within a group may vary
Keep these points in mind. The leading selected card still has to meet the destination rule. The selected cards do not need to descend in rank to travel together. The selected cards do not need to share a suit to travel together. Any face-up card can be selected together with every card beneath it.
Only Kings fill empty space
Keep these points in mind. A group led by a lower rank cannot enter an empty column. An empty column accepts a King or a group led by a King. Cards beneath a moved King do not need to be in sequence. An empty column is therefore less flexible than an empty column in ordinary Spider.
Reveal the hidden cards
Removing all face-up cards above a hidden card turns that hidden card face up. An exposed card can carry the cards beneath it when its own destination is legal. Undo restores the earlier hidden-card arrangement when the move is reversed. The next hidden card is revealed automatically.
Use the stock once
Keep these points in mind. There are no further stock cards after the three-card deal. Dealing places a face-up card on each of the first three columns. This Scorpion version permits its stock deal when columns are empty. The stock contains one final deal of three cards.
Complete a suit
The game removes a qualifying run automatically from the bottom of a column. All thirteen cards in a collected run must be face up. Moving an unordered group does not make that group a completed sequence. A completed run must descend from King to Ace in one suit.
Plan around blocked cards
A few details help explain this feature. A move can carry unwanted cards along with a useful leading card. Hint lists legal choices without promising a winning continuation. Replay and Undo let you explore another approach to the same layout. Checking the whole moved group helps you anticipate what will become blocked.
