Beyond a library of original Vietnamese ghost stories and folk legends, every Mystery Case is a fair-play whodunit: explore the scene, gather clues, decode ciphers, and interrogate suspects who lie — then accuse, naming the culprit, weapon and motive. Investigation is turn-limited, so every choice matters; the solution unlocks only after you commit. New cases and multi-chapter horror arrive regularly, free to read. In English, Vietnamese, Korean & Japanese.
