Russian roulette is a potentially lethal game of chance in which a player places a single round in a revolver, spins the cylinder, places the muzzle against the head or body (their opponent's or their own), and pulls the trigger. If the loaded chamber aligns with the barrel after cocking (with a single-action revolver), or is in the position which will be rotated to the barrel upon pulling the trigger (double-action), the weapon fires.
