About This Game

The story flips on your second playthrough.

The heart of this game is the moment the story turns itself inside out on your second run.

Who is the real villain? What is K still carrying? We hope you'll find the truth.

What kind of story is this?

A slow, tightening tension — and grief for something that can never be taken back.

A cyberpunk noir about suspense and loss.

Cross the line. Learn the price of a life.

The megacity of Neo Babylon. Only one clause remains in its law: the moment a person's hidden assets exceed one trillion dollars, they lose the right to live. You are K. You enforce that line.

But the numbers begin to lie. With every execution, one question presses closer to your throat: who decides what a human life is worth? And what if the system itself is the crime?

Every choice rewrites the story

Your judgment reshapes the plot, the people who stand beside you, and the ending you reach. Five endings. Two main routes. No choice is forgotten — a decision in the first hour changes who is still alive at the end.

More than just reading

Hack terminals, route signals, break security — tactile minigames woven into the story. Not busywork: these are the moments K's hands move when his conscience can't.

One hidden ending

Only those who reach the TRUE END will unlock an extra chapter. You won't see it coming.

What is a human life worth? Cross the line and find out.

Languages: English / Japanese (full text). The game detects your system language, and you can switch anytime from the title screen.

AI Generated Content Disclosure

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

This game uses AI-generated content. Background and character artwork was created with the assistance of generative AI image tools and edited by the developer. The English localization was produced with AI assistance (a large language model) and reviewed. All such content is pre-generated during development; nothing is generated live during gameplay.

Mature Content Description

The developers describe the content like this:

THE 13th Digit is a story-driven visual novel about state-sanctioned execution. The player character, K, is an executioner who carries out death sentences on people whose hidden wealth exceeds one trillion dollars.

The game depicts violence and death: characters are shot and killed on screen, including scenes of execution. Violence is shown in a stylized, hand-drawn art style — there is no dismemberment, torture, or graphic gore. It also deals with mature themes such as capital punishment, the value of a human life, institutional corruption, and moral responsibility for killing. There is one passing textual reference to a character discarding a cigarette.

The game does not contain sexual content or nudity, sexual assault or non-consensual sex, BDSM, drug abuse, self-harm, or suicide.
