I worked pretty hard to try to make sure that doesn't happen, but it's a complex generator and bugs do happen. If you believe you've encountered a bad generator, you can send me the clues and I'll review them (make sure you found them all though - see below for how to do that).
Not sure how familiar you are with puzzles like this, but there are a couple of tricky clue types to watch out for that give more information than they seem. For instance, if it says that Eustace was neither the person with the straight razor nor the person in the master bedroom, you know three things, not two things:
- Eustace didn't have the straight razor.
- Eustace wasn't in the master bedroom.
- AND the person with the straight razor was not the person in the master bedroom.
A lot of people miss that third deduction, but it will be key to solving the mystery.
Similarly, the clue that shows a photo with a bunch of people, some named, some with a weapon, some being in a room, or some with a motive, can be a gold mine of deductions, but you have to go through all the individual pairings to make notes that each person is distinct. It can be easy to miss a pairing, so doing it methodically helps.
And I personally still struggle with using the grid itself to do the deductions. When I have checkmarks that line up, it's easy, but I always have to double-check my logic when I use the grid to discover more cross-outs. It's easy to miss opportunities to cross out cells from grid deductions!
Finally, you can visit the inspector on the front porch to find out whether you've found all the clues in the mansion. If you're missing something, he'll give you a suggestion where to look. And he's always got one last clue to give you which only comes to light once you find all the other clues – the one that determines the murder weapon from the lab.
Anyway, thanks for playing. Hope this helps.
