Traditional Russian Roulette has one major element which tends to prevent repeat play- someone usually takes a bullet in the head.
This Japanese adaptation of the game won't kill you, it'll only sting a little when the thumbtack sticks in your head.
That's right, simply attach a thumbtack to the front of a Nerf dart and you've got one hell of a way to put your eye out!
