Most Difficult: Solitaire

At first glance, the layout looks manageable. In Most Difficult: Solitaire, the real pressure comes from the Scorpion rules, with card movement staying flexible until the empty spaces demand a king. Four home cells wait at the top, and the whole deal ends only after every card lands there in suit order.

How to play?

Build descending suit sequences across the tableau, since mixed suits won't travel together. Onto an empty cell, place only a King, even if another rank would fit the chain you want. From any spot on the table, lift a valid run and reposition it to continue the stack. If the layout stalls, use the computer hint for advice on the next move.
