Only a certain amount of Death Note Spaces can be placed per map. Death note Spaces will kill any investigator who crosses them within the next two turns, but after those two turns, they will merely turn into a scrap of paper, visible to the investigators. The Death Note can be used to set a Death Note Space, or it can be transferred to another Kira character. When using Kira, one of your characters possesses the Death Note. The rules are relatively simple, but vary slightly between the Kira and L sides. The game is played as if it were a board game.
