What is a Murder Mystery Game Simulator?

Murder mystery games are party games that revolve around a simulated murder investigation. Players, often referred to as guests, are assigned characters and work together to solve the mystery of who among them is the killer.

These games are often held at dinner parties, but can also be played over video call platforms like Zoom.

What does the host do at a murder mystery party?

The host of the murder mystery game typically provides the guests with information about their characters, including their motive for murder and their alibi for the time of the crime.

Clues and evidence are scattered throughout the event, and it is up to the guests to gather and interpret these clues in order to determine the identity of the killer.

What happens in a typical Murder Mystery Simulation?

As the guests investigate, they may question one another and consider the various motives of the suspects. Some murder mystery games even include a trial or hearing, where a judge and jury are selected among the guests and the killer is sentenced based on the evidence presented.
