Hi Product Hunt! I'm the developer of Casebook on SnackTurn.
September 19 update: the main collection now has 48 deduction cases, with 12 each in Expert, Master, Grandmaster and Legendary.
The progression changes what you have to reconstruct: Expert has linked answers; Master requires a full arrangement of people and objects; Grandmaster connects that arrangement to inspection times; Legendary follows the opening state, three exchanges and all resulting snapshots.
You submit the complete report together. A wrong report keeps your work and does not reveal which individual field is wrong. The notebook has separate sections, a written memo and three groups of optional hints. Solving opens the complete explanation.
The original 36 cases and three older files remain in Historical files, with their saved progress. The new levels' difficulty and duration estimates still need player calibration.
It's free to play in English or Simplified Chinese, with no account, download or timer. Progress stays in your browser.
