Le célèbre jeu de Bruno Cathala et Ludovic Maublanc sur Jack l'éventreur continue de faire des adeptes. Un petit rappel sur ce palpitant jeu à deux joueurs ? Mr Jack propose à l'un des joueurs de se glisser dans la peau des enquêteurs. Par déductions successives et en plaçant les personnages dans l'ombre ou dans la lumière, le joueur doit trouver sous quelle identité se dissimule l'infâme Jack et tenter de la capturer. Son adversaire, Jack fait tout son possible pour retarder l'enquête. Il essaie même de profiter de l'obscurité pour quitter définitivement les lieux.
In Mr. Jack, one of the two players represents Jack the Ripper, who will be one of the eight characters on the board. This player knows which character is Mr. Jack, and his goal is to flee from the district as soon as possible (or avoid being accused for eight turns). The other player represents an independent investigator (not represented on the board) who tries to guess the identity of Jack — but he can make only one accusation during the game!
During each turn, the players move the characters, using their special powers and placing them either in shadow or light. At the end of each turn, the witnesses declare whether Jack is visible — that is, in light or adjacent to another character — or not (alone in the shadows). This allows the investigator to know which characters are innocent. As the turns progress, the investigator tries to eliminate suspects while Jack tries to escape. Intuition, logic, and cold blood will be necessary for each of the two participants.
