The description of Durak - Play With New Friends
Durak (Fool) limits the number of players to 6. The deck of 36 cards is shuffled, and each player receives 6 cards. The top card on the remaining deck is made visible and placed at the bottom of the deck across it (so that its denomination is seen). This determines the trump suit and the revealed card is actually part of the deck, the last card to be drawn. The player to the attacker's left is always the defender.
