Build descending piles outward, and only a king opens a corner.
A solitaire-shaped game played against other people. You build descending, alternating piles outward from a central stock, and only a king may open a corner.
A 52-card deck. Seven cards each. The rest goes face down in the middle as the stock, and four cards are turned face up around it — above, below, left and right — as the four foundation piles.
Those four piles are the crosses. The four diagonal spaces between them are the corners, and they start empty.
Draw one card from the stock, then play as many cards as you can:
Onto a pile, a card one rank lower and of the opposite colour. A red nine goes on a black ten. Into an empty cross space, any card. Into an empty corner, a king and nothing else.
You may also move an entire pile onto another pile, if the bottom card of the one you are moving fits the top card of the target. That frees a space, and it is the move that wins games.
When you cannot or do not want to play any more, your turn ends.
The first player to get rid of every card in their hand wins the round.
Everyone else counts what they are left holding: kings 10, all other cards 1. Play to an agreed total — 25 is a good length — and the lowest score wins.
