About This Game

Turtle Soup World Demo is a lateral-thinking mystery game built around yes-or-no questions. You begin with a strange story that looks simple but hides crucial details. Explore locations, inspect objects, talk to NPCs, and ask the Turtle questions to eliminate wrong possibilities and reconstruct the complete truth behind each event.

A deduction adventure that begins with "yes" and "no."

Start with the "soup surface"

First understand the story as it is told and remember every ordinary-looking detail. The real clue is often hidden in the part of the narration that is easiest to overlook. The truth may also involve facts never mentioned in the soup surface.

Ask the Turtle

Ask questions that can be answered only with "yes," "no," or "yes and no." Confirm important facts and gradually narrow down the possible truth.

Explore the scene and find clues

Freely explore the place where the story happened. Watch for changes in the environment, suspicious details, and things that may have been missed.

Talk with NPCs

Learn about relationships through conversation and observe how each person reacts. Hidden information can emerge from only a few words.

Highlight important dialogue

Pay attention to specially marked lines of dialogue. They may contain the key information needed to move your deduction forward.

Investigate objects in the scene

Examine objects in the environment, connect scattered clues with confirmed facts, and piece together a more complete story.

Organize clues and submit your theory

When you believe you are close to the truth, organize the clues and submit a complete theory. The system evaluates how closely your answer matches the real story; reach 80 points to pass the current story and reveal the true "soup bottom."

Choose your deduction method

The game supports cloud-based large language models. Enter your own API key to connect with one instantly. This option lets the game run smoothly even on low-spec computers and usually makes deduction faster. Cloud models may incur a small fee. If you prefer your own local large language model, open the game's ai_runtime/models folder and replace the .gguf file with your own .gguf model file.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

The game will connect to an open-source local large language model that is already built into the game upon first launch, and use it during gameplay to generate NPC dialogues, host responses, and reasoning review feedback. Players may also choose to access compatible third‑party large language model APIs. The text generated at runtime is based on player questions and current story data.
