Durak is a free Android card game developed by Mirenad. The objective of the game is to get rid of all the cards in your hand before your opponents. The game can be played with 2 to 6 players and starts with each player being dealt six cards. The remaining deck is placed face down on the table, and the top card is turned face up to start the discard pile.

Players take turns attacking and defending until one player runs out of cards. The defending player must beat the attacking card with a higher card of the same suit or use a trump card to win the round. The game also includes some additional rules, such as the ability to "pass" your turn and not attack, or to "throw in" extra cards to increase your chances of winning a round.

Overall, Durak is a fun and challenging card game that offers hours of entertainment. The game's simple rules make it easy to learn, but its strategic depth ensures that it remains engaging even after multiple plays.
