A disguise master roams the city pretending to be innocent citizens. Unmask them.
Your goal is to figure out who is a detective and who is a killer.
Based on the known evidence, tap on a suspect to choose detective or killer. They must be either a detective or a killer. They might reveal new evidence.
Everyone tells the truth, even those on the killer side.

Think of each grid location as a statement about its row and column. A reveal might prove one character's role and rule out another, so try to chain these facts together rather than treating each box in isolation.
Quick tactics for new players:
You can always step away mid-puzzle and return later; the board state and your reveal streak remain saved in the browser. Take your time and enjoy the mystery.
