Dossiers Criminels is a brand of immersive, cooperative investigation games designed to bring the experience of solving a case into the home. Players take on the role of detectives, examining evidence, comparing witness statements, reconstructing timelines and solving puzzles to identify the culprit. The games combine crime mysteries with escape-room-style mechanics and can be played solo or with up to six people, making them suitable for couples, families and friends.

The range includes XL investigations, Pocket cases and bundled packs, with options for beginner, moderate and experienced players. XL cases typically take around 1.5 to 2.5 hours and combine a physical game box with a dedicated online interface. Pocket investigations use cards contained in a compact pouch, require no additional digital interface and take about 45 minutes. The catalogue features themed cases such as Disparition aux Caraïbes, Les Fantômes de Brandonsbury and Le Secret des Yakuzas, as well as a Stranger Things investigation. Dossiers Criminels also provides online hints to help players progress and verify their conclusions.
