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 their head, and pulls the trigger. "Russian" refers to the supposed country of origin, and roulette to the element of risk-taking and the spinning of the revolver's cylinder being reminiscent of spinning a roulette wheel.
Because only one chamber is loaded, the player has a one in n chance of hitting the loaded chamber, where n is the number of chambers in the cylinder. So, for instance, for a revolver that holds six rounds, the chance is one in six. That assumes that each chamber is equally likely to come to rest in the "correct" position. However due to gravity, in a properly maintained weapon with a single round inside the cylinder, the full chamber, which weighs more than the empty chambers, will usually end up near the bottom of the cylinder when its axis is not vertical, altering the odds in favour of the "player" - but only if the cylinder is allowed to come to a complete stop before the cylinder is relatched.
- 'Did you ever hear of Russian Roulette?' ... With the Russian army in Romania, around 1917, some officer would suddenly pull out his revolver, put a single bullet in the cylinder, spin the cylinder, snap it back in place, put it to his head and pull the trigger.
It is claimed, that this practice was widely known in Russia in the early 19th century. However, there is only one written source before 19th century: in Mikhail Lermontov's 1840 "The Fatalist", one of five novellas comprising his A Hero of Our Time, a minor character survives a version of Russian roulette.
Legal case (Pennsylvania, United States)
In Commonwealth v. Malone, 47 A.2d 445 (1946), a Pennsylvania teenager's conviction for manslaughter as a result of shooting a friend during a game of Russian roulette was upheld by the Pennsylvania Supreme Court. The court ruled that "When an individual commits an act of gross recklessness without regard to the probability that death to another is likely to result, that individual exhibits the state of mind required to uphold a conviction of manslaughter even if the individual did not intend for death to ensue." It is worth noting, however, that in the Malone case the teenagers involved played a modified version of Russian roulette in which they took turns aiming and pulling the trigger of the revolver at each other, rather than at their own heads. It has not yet been established whether simply participating in a game of Russian roulette in which another participant kills himself by his own hand would constitute manslaughter or some lesser form of conspiracy or homicide.
Numerous incidents have been reported regarding Russian roulette.

In popular culture
Russian roulette has been portrayed in many different works of modern culture.
- Russian roulette was made famous worldwide with the 1978 film The Deer Hunter, which features three soldiers who are captured during the Vietnam War and forced to play Russian roulette as their captors gamble on the results. Their captors demand an especially brutal variation of the game: the game is played until all but one contestant is killed. The game takes place in a bamboo room above where the other prisoners are held, so that the losers' blood drips down on future contestants. Several teen deaths following the movie's release caused police and the media to blame the film's depiction of Russian roulette, saying that it inspired the youths.
