Russian roulette

Russian roulette is a game of chance with a potentially lethal outcome. Russian roulette is not played at a roulette table. Instead, the player places a single round in a revolver and spins the cylinder. The player then places the muzzle against their head and pulls the trigger. The term Russian roulette is believed to be an allusion to the similarity between the spinning of the revolver’s cylinder and the spinning of a roulette wheel. This is a game that is NOT to be played and belong mainly in fiction.

Russian roulette can be played alone or with others, and it can be played with our without respinning the cylinder between rounds. When Russian roulette is played by more than one player, the gun is passed around.

Russian roulette with respinning

  1. The player spins the cylinder.
  2. The player places the muzzle against their head and pulls the trigger.
  3. If the player is not shot, the player respins the cylinder before carrying out point 2 again.

Since the cylinder is spun before each round,ach successive turn has an equal probability of shooting the player in the head. If a standard six-round cylinder is used, the probability of getting shot is approximately 1/6. (It is not exactly 1/6 since factors such as the weight of the bullet and the angle of the gun while the cylinder is being spun can bear upon on the outcome.) It is theoretically possible to survive an endless number of rounds.

Russian roulette without respinning

  1. The player spins the cylinder.
  2. The player places the muzzle against their head and pulls the trigger.
  3. If the player is not shot, the player carries out point 2 again without respinning the cylinder first.

At point 1, the probability of being shot is approximately 1/6. For each time point 2 is carried out without anyone getting shot, the probability of firing a shot at the next round increases.

  • The second time the trigger is pulled, the risk of being shot is 1/5.
  • The third time the trigger is pulled, the risk of being shot is 1/4.
  • The fourth time the trigger is pulled, the risk of being shot is 1/3.
  • The fifth time the trigger is pulled, the risk of being shot is 1/2.
  • The sixth time the trigger is pulled, the risk of being shot is 1.

Thus, this type of Russian roulette can only be played a maximum of six rounds before a shot is fired, assuming that a standard six-round cylinder is used.
