It is a game of skill and can be played by two to six players playing individually or with four people, playing in two teams of two.

Durak uses the Russian deck of 36 cards or can be played with a standard deck of cards with the 2-5 inclusive removed.

Popular variants of the game include Podkidnoy Durak (Throw-In Durak) and Perevodnoy Durak (Transfer Durak) where the key difference is that in Perevodnoy Durak a defender may pass the attack to the next player by playing a card that matches the rank of the attacking card.
