The game uses a deck of 36 cards. Participate from two to six players. The seniority of cards in a deck of 36 cards (from lowest to highest): 6, 7, 8, 9, 10, B, D, K, T. The seniority of suits for playing the fool is not defined. Each is dealt 6 cards, the next (or the last, possibly any of the deck) card is revealed and its suit sets the trump card for this game, and the rest of the deck is placed on top so that the trump card is visible to everyone. The ace of trump in the game does not fight back. The object of the game is to get rid of all cards. The last player who does not get rid of the cards remains in the "fools". The game of the fool is called "con". The repulsed cards go to the “release” (“bat”) and are folded face down on the table.
