Overview

Last Message is a party/deduction game where a crime has been committed and the Victim must help Detectives identify the Criminal hidden in a crowded crime scene illustration. The Victim draws clues on erasable boards, but the Criminal erases portions of those clues each round to cover their tracks. The game plays over 4 rounds – if the Detectives identify the Criminal, they and the Victim win; otherwise the Criminal wins.

Components

Setup

  1. Choose one player to be the Victim and another to be the Criminal. Both sit on the same side of the table, behind the screen.

  3. Choose 1 of the 6 crime scenes; place the 4 illustration sheets in front of the Detectives.
  4. The Criminal places the folded illustration for that crime scene in front of themselves and the Victim (hidden from Detectives).
  5. The Criminal secretly chooses any character in the illustration and places the transparent token on it.
  6. The Victim takes the 4 erasable boards and one marker. The Criminal takes the sand timer and the other marker.
