Find the Killer is a crime investigation and logic game where every clue matters. Each case presents a different murder mystery with its own story, locations and hundreds — sometimes thousands — of suspects. Your task is simple to understand, but not so easy to solve: analyze the clues, eliminate everyone who cannot be guilty and discover the real killer. The suspects are divided into different areas connected to the crime scene, the victim or the events surrounding the murder. As the investigation progresses, you will receive clues about their names, locations, professions, credentials, relationship to the victim and other details. Read every clue carefully and use logic to narrow down the list. Some clues may tell you that the killer's name does not contain a certain letter, that they were not in a particular area, that they do not have a specific profession or that they had a certain relationship with the victim. Apply each piece of information correctly until only one suspect remains. Every case has one solution. There is no random guessing and no hidden trick. The clues have been designed to lead you logically to the culprit. But be careful: eliminating the wrong suspect could ruin your investigation.
