Interactive investigation · no installation required

Online detective game in English

Become an investigator. Read testimonies, compare hours, eliminate impossible connections and identify the person responsible for the crime.

What is the game about?

Every investigation begins with a case file. You learn about the suspects, locations and possible tools, and then read the numbered clues. Information must be combined into one coherent picture. The deduction table helps with this, where you mark confirmed and excluded relationships.

This is not a quiz with random answers. The game was designed so that you can reach the solution step by step. If you like crime stories, logic puzzles, escape rooms or murder mystery games, you will quickly find yourself in the role of an investigator.

One logical solution

Any verdict can be justified by the information in the file.

No time pressure

There is no countdown. What matters is the quality of reasoning, not the speed of clicking.
