- Korean-reading mystery-puzzle players
- Worth noticing
- Each season links five standalone cases to a semifinal and finale; the homepage says clues and twists stay within the stories.
Field notes
The index gives each case a star-rated difficulty, estimated solve time, and number of locks; examples range from a missing moon jar in an old Andong house to locating a caller from sounds on a recorded phone call. The site’s stated rules say every necessary clue appears in the story, answers are singular, and twists must be supported by clues already shown. Later files remain locked until earlier season milestones are completed.
