Free Detective Mystery Game Tool for Couples

Many couples look for engaging ways to spend time together at home. The Casebook provides a free co-op detective mystery game designed for two players, offering an interactive experience without any signup or paywall.

Solve a Mystery Together with The Casebook

The Casebook is a monthly co-op detective mystery game for couples aged 18 and over. It transforms your couch into a crime scene for an at-home date night. This asymmetric two-player game assigns one partner to the Evidence Board, which includes crime-scene photos, documents, and a timeline. The other partner works with the Witness Files, containing interview transcripts. Neither player can solve the case alone; the game encourages conversation as you share what you see, connect witness statements to physical evidence, and unlock hidden clues.
