It is a form of entertainment for adults that combines the atmosphere of a crime story with the mechanics of a classic logic puzzle.

What practice solving cases?
Investigations require keeping several pieces of information in mind, comparing timelines, and distinguishing facts from assumptions. They help you practice concentration, eliminative reasoning and accurate reading.
You can solve one short case a day or choose more difficult series when you want a longer session.
How to start?
Open the free case of the day, read the file without rushing, and then mark the sure and impossible relationships in the table. Only bring an accusation when all the circumstantial evidence forms a coherent whole.
