Rules of Solitaire. Before unfolding the solitaire deck carefully folded and put on the center of the table in a closed form. Then the top 4 cards are taken from the deck and laid out openly on the table in the form of a quadrilateral. If among these cards there are two cards of the same suit, they are laid aside, and instead of these cards, two other cards are taken from the deck, which are put in clear view of these vacant seats. Then they again look at the cards for the presence and removal of cards of the same suit. Thus, the solitaire is unfolded until 4 cards of different colors are placed on the table.

Solitaire converged if there is not a single card left in the deck.
