Scorpion Solitaire: Coach

Scorpion is the hard one in the Spider family: one deck, seven columns, the top three cards of the first four columns start face down, and any pile moves as a block whether it is in order or not. One careless move can bury the card you needed.

This version is built for people who want to get better at it. Undo is unlimited, so you can explore a line and walk it back. "Guide me" highlights a legal move and says what to do, and points you at Deal 3 when no card fits. The page has a strategy section: dig out face-down cards first, keep a King free for an empty column, save Deal 3 for when you are truly stuck. There is a Daily deal that is the same for everyone that day, a day streak with one free freeze if you miss a day, and a share button for your result.

Not every Scorpion deal is winnable. That is the game, not a bug.
