Passive Russian Roulette (受動ロシアンルーレット) is a game invented by Kurimu Terasumi in Kakegurui Midari. Kurimu plays against Midari Ikishima and Ayame Nureba together.
Rules[]
The game is played with a five-shot revolver. The first player loads a single bullet in the gun in whatever spot they prefer. Then, the opponent has to declare a number between one and nine; the player rotates the cylinder by such number. Finally, the player can shoot. If there is no bullet, the player has to rotate the cylinder and do it again. If no bullet comes out after four times, the two players switch places with each other.
The player who finds the bullet loses.
Kakegurui Midari[]
In order to get away from paying her debt, Kurimu suggested this game. But Kurimu didn't have enough courage to actually fill any bullets in, so the barrel was completely empty the entire time. She was simply hoping to intimidate them until they gave up. This made Midari very angry, when she found it out and she called Kurimu a coward.
