Resolve the shadowy puzzle
Shadowslavedle is a daily deduction browser game inspired by the hit webnovel Shadow Slave written by Guiltythree. Every day, the Nightmare Spell selects a new mystery character, creature, or concept from the waking world and the Dream Realm. Your goal as an Awakened is to guess the correct answer using logic, lore knowledge, and deduction.
Select your preferred game mode from the menu above. In the Classic mode, type the name of any known character into the search box. The system will provide color-coded clues to guide your next guess. A green tile means the trait (such as Gender, Rank, Affiliation, or Debut Volume) matches the daily target perfectly. A red tile means it is incorrect.
You can also test your knowledge of the Nightmare Creatures in the Bestiary, decipher ancient lore in the True Name mode, or solve the weekly Shadow Grid puzzle. Use your knowledge of the Great Clans, the Forgotten Shore, and the various human ranks to narrow down the possibilities.
Whether you are a Sleeper experiencing your First Nightmare or a Transcendent Saint, this unofficial fan project will test your memory of the novel's vast universe. If you need a refresher on the ranks, cores, and classes, visit our comprehensive Lore Database. May you survive the trial.
