Pyramid Thirteen, deal #20

About this deal

This is one of the harder deals of Pyramid Thirteen: only 0% of the quick simulated games won it, and the solver had to search for a while before finding the way.

The bottom row starts with Ace of Spades, 10 of Clubs, 4 of Diamonds, 6 of Diamonds, 10 of Diamonds, 4 of Clubs and King of Spades, and the 6 of Spades sits at the very top.

None of the bottom cards add up to 13 with each other, so the first help has to come from the stock.

2 Kings lie in the pyramid; each one leaves on its own as soon as nothing rests on it.

14 times a card lies across one of its own partners, so those two cards can never leave together and need other partners.

The most crowded value is 5 with 4 cards in the layout, while only 1 of its partners (8) are in the layout too; the rest come from the stock.

The solver's winning line has 66 moves.

How to approach it

• Start by naming a partner for each locked card. If both partners of a locked card are also in the pyramid, free them first; otherwise wait for one from the stock.
• Because nothing pairs at the start, turn the stock slowly and look at what each new waste card could free before you use it.
• This is a hard deal: use undo to test an idea, and the hint button if you are completely stuck.
