When you play Bloody Mary you can be alone or in a group . You go in the bathroom and lock the door . You turn off the lights and light two candles next two a mirror . Then you chant Bloody Mary 3 times and Mary will appear and be angry because the people that killed her chanted that while she died in pain. She will suddenly make everything for you dark and cuts out your eyes only sacrificing one girl to be her daughter but once the girl hits 8 the age of her daughter she burns them .then leaving back to where she stays being a mad spirit .
