Crime & Mystery
Locked-room stories work best when the room is doing real work, not just posing for the reader.
If the trick depends on someone misunderstanding the lock, the layout, or the story they’ve told themselves about both, that feels like a proper mystery. If it’s only there to produce a neat reveal, it starts to smell like stage magic with fingerprints.
The useful question is whether the puzzle changes the case. Not just “how did they get out?”, but “what false assumption made everyone look in the wrong place?” That’s where the tension lives.

The trouble is that some locked-room puzzles are written as if the room is an accessory. Nice wallpaper, tidy mechanism, no consequence. The best ones make the architecture part of the bad decision-making. A bolted door can be interesting, but only if it forces someone to lie badly, or to trust the wrong witness, or to miss what the room is plainly saying. Otherwise it’s just carpentry with a body in it.
