Spider's single-deck cousin. The goal is to build four complete King-to-Ace runs, each of one suit, within the columns.
Scorpion belongs to the same family as Spider and Yukon — the solitaires where you stack down by suit and have to “dig out” the cards trapped underneath. Its exact origin is uncertain, like that of many classic patiences recorded in collections through the 20th century.
Played with a single deck, it is one of Spider's most tactical relatives: you can move any face-up card, carrying everything on top of it, even out of order — so each move shifts whole blocks of a column.
The name is thought to evoke how hard it is to escape once an important card is buried — a trap that, like a scorpion's, is difficult to get out of. It found a modern audience in computer game packs, alongside Spider and FreeCell.
