This Penguin begins with three aces on their foundations. Seven columns of seven hold the other 49 visible cards, including the remaining ace of spades.
Suited runs need a king for an empty column
Build down by suit. Ordered descending suited runs can move together, but only kings or king-led runs fill empty columns. Each of the seven reserve cells holds one card. Foundations build upward by suit from ace through king; there is no stock or rank wrap.
Find the spade ace’s route first
Locate the remaining ace and inspect its blockers. A cell can hold a card that lacks a suited receiver, but decide where that card will go afterward. Seven occupied cells can stop a rearrangement even when the whole deck is visible. Clearing other low ranks may create a route without spending another cell.
