About This Game

Cross the line. Learn what a life is worth.

In the megacity of Neo-Babylon, the law has one final clause: the moment a person's hidden wealth crosses one trillion dollars, they forfeit their right to live. You are K — the executioner who enforces that line.

But the numbers have started to lie. As you carry out one execution after another, a single question tightens around you: who decides the value of a human life — and what happens when the system itself is the criminal?

A story that branches on every choice

Your decisions reshape the plot, the people at your side, and the ending you reach. Five distinct endings. Two full routes. Nothing you do is forgotten — a choice in the first hour can change who lives in the last.

Cyberpunk noir, told with intent

Hand-drawn art, a rain-soaked dystopia, and a terse, hard-boiled script. Investigate crime scenes, read between the lines, and assemble the truth from what people refuse to say.

More than just reading

Hack terminals, route signals, and crack security in tactile minigames woven into the story — not busywork, but the moments K's hands do the work his conscience can't.

One hidden ending

Reach the TRUE END and a bonus story opens — one you won't see coming.

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

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.
