Welcome to Crime City, a place where crime lurks around every corner. Disastrous secrets, devious robberies, and cold-blooded murders are the order of the day here. The local police are no longer able to control the situation, so the work of clever investigators is required. MicroMacro - Crime City is a cooperative detective game where players solve 16 tricky criminal cases by determining motives, finding evidence, and convicting the perpetrators. An attentive eye is just as important as deductive talent to unravel every riddle on the 75 x 110 cm game board. A magnifying glass is included to help find every detail.

One player takes on the role of Lead Investigator and is responsible for reading the case cards aloud, while also assisting in solving the case. Players choose together which case to play, and the Lead Investigator reads the corresponding start card and the first task. Together, players explore the map of Crime City to answer all the questions on the case cards, one after another. The game ends as soon as the last case card has been answered correctly.
