Russian Roulette is a dangerous game of chance in which a player places a single round in a revolver, spins the cylinder, and then pulls the trigger. The player has no way of knowing if the chamber with the round is in line with the barrel, and thus whether or not they will be shot. A wager in this game is a bet placed on the outcome of the spin. In Russia, the currency used for such a wager is the Ruble.
