Jack & Detective

Jack & Detective is a turn-based game of deduction in which Jack the Ripper and the detectives compete to outwit one another. Jack tries to commit murders without being identified, while the detectives investigate and vote to arrest him. Players cannot talk to each other, so you must infer the truth from their actions. No one is eliminated, and matches last about ten minutes.

Roles and objectives

Players are assigned roles at random at the start of each game. Jack wins by avoiding selection during the voting phase. The detectives, private investigators hired by the London police, win by correctly voting Jack out. Jack’s maniac supports him and wins if Jack wins, even if the maniac is voted out.

Investigate London

At the start, everyone places their token on a London tile of their choosing. Night then falls and Jack commits his first murder, though in some cases no murder occurs on the first night. After the second murder, the voting phase begins: detectives near the crime scene become suspects, and everyone votes for the person they believe is Jack. Detectives work to corner the suspect while Jack tries to mislead them and frame someone else.
