An interesting and rather difficult solitaire game. Catherine II really liked this solitaire. In the Solitaire "Ekaterina" you need to arrange all the cards from the deck in four horizontal rows, in ascending order by suit from left to right starting with the twos, using your mouse. You can only place cards that directly follow in ascending order of the same suit (for example, you can place a 9 of spades after an 8 of spades, and no other), nothing can be placed after a king. You are given ten minutes to play the solitaire, and to make it easier, cards available for moving are highlighted with a green border.
