A murder mystery party is an interactive game where participants take on roles of characters in a fictional scenario, centered around solving a murder. Each participant is assigned a character with a backstory, motivations, and secrets, and they interact with each other to gather clues, uncover hidden agendas, and ultimately identify the murderer among them. The game involves non-scripted interactions, clues hidden throughout the venue or provided by the host, and sometimes puzzles or challenges to solve.
