Inside Mystery Files

Explore the scenes and details.

Mystery Files turns the difference mechanic into a narrative device. The missing object on a desk or changed detail in a hotel room can matter twice: first as a puzzle target, then as a clue in a larger case.

Stories remain original Spotly fiction. The system keeps puzzle fairness separate from narrative surprise, so a player never needs outside knowledge to find a difference even when the scene belongs to a longer mystery arc.

How differences are designed here

Missing evidence, altered objects, changed dates represented without legible real-world documents, swapped keys, map markers, display pieces and room details.

Puzzle quality

What to expect from each Mystery Files scene.

All story content must be original.

Do not imitate famous detectives or copyrighted mystery franchises.

Puzzle targets must remain findable without solving the story first.

Ambient motion profile

Animation supports the world without moving puzzle targets.
