What Is Murder Mystery?


Murder Mystery, often referred to as 'Mada-Misu', is an interactive game where participants assume the roles of suspects in a fabricated crime. Players dive into unparalleled engagement, unraveling mysteries in a manner reminiscent of captivating detective novels. Boasting a staggering popularity in China with over 40,000 venues, it's a trend that has also gained incredible traction amongst the youth in Japan.
