Solitaire variant

Scorpion Solitaire

49 cards are dealt into seven columns — the first four columns have three face-down cards with four face-up cards on top; the last three columns are entirely face-up. Three cards are held in reserve. Move any face-up card (together with every card stacked above it) onto a card of the same suit that is exactly one rank higher. Only Kings may fill empty columns. Build all four suit sequences from King down to Ace to win.
