Svoyi Koziri, Svoi Kozyri or Vsyak svoi kozyri, is a Russian going-out card game for two players which some consider an elaboration of the Czech game Sedma. This game is one of perfect information and hence entirely of foresight and calculation. It differs from almost all other card games, in that the element of luck is eliminated, as, at any one time in the game, a player will know exactly which cards his opponent has.
