I am doing a whodunnit blog game that actually depends on finding out who dun it! (Puns) there are 13 slots, and one is the "magic slot" that means that whoever gets it is the killer.
After every episode, you have to guess who is the killer. If you get it wrong, you will be in danger. If everyone answers the same (except for one of course), then you will have to guess the murder weapon.
