I love that the game makes you deduce things but unfortunately, if you’re stuck on an extended mystery, there are no in-game hints and all the guides I’ve found give you the final solution. I made this guide in case anyone needs a little help but doesn’t want to skip the deduction process
General tips
- There are references to real-world people and companies. If something is hinted at but no in-game name is provided, you should try putting real-world names in the search box
- Some mysteries don’t appear in the ‘Close case’ tab until you find a certain unlocking clue (i.e. you can find clue B which is the correct answer to the mystery but you can’t submit it unless you find clue A first). I added hints for unlocking clues that aren’t essential for solving the case
- Every case has an unlocking clue which contains a puzzle
- All of these clues are locations that don’t play any role in the case
- You can freely switch between cases to look up various info (e.g. use action clues with new data) and click Close Case to check the questions (and then return to the case screen)
