About Turtle Noir

Turtle Noir is an AI-hosted mystery puzzle site for players who enjoy yes/no riddles, hidden-context stories, and collaborative deduction. You can play solo, invite friends, or submit your own puzzle ideas.

What this site is

Turtle Noir is a browser-based mystery game and puzzle library. Each case starts with a strange setup, and the AI host answers yes, no, or irrelevant while players uncover the hidden truth.

Who it is for

It is built for players who like mystery riddles, structured deduction, and party-style puzzle sessions without needing a human moderator.

How it works

Read the case, question the AI host, and keep narrowing possibilities until the strange setup makes sense. You can also create rooms and share them with friends.

Languages and regions

Turtle Noir serves international players on the main domain and uses a dedicated Japanese entrance for Japan-focused content and indexing.

Pricing and access

The core experience is free to start. Players can explore cases, learn the rules, and decide later whether they want more advanced features.
