## What is ShimenSoka?

ShimenSoka is a quiet ink-painting puzzle for a focused mind.

The maze is fully visible. There are no walls to discover, no fog to clear. And yet only one route is correct — because the real puzzle is hidden in the colors.

Every gate you pass has a color, and the rules act on the history of colors you have already walked. "Never red after green." "Visit blue twice." "Pass yellow last." The open path stays open, but your own choices quietly close it around you, until a single clean line remains.

The name 四面楚歌 — "songs of Chu on all four sides" — is that feeling: surrounded not by walls, but by your own logic.

WHAT YOU DO
- Walk a visible maze with a simple directional pad.
- Read the rules, then watch your color history narrow the answer to one route.
- No timer, no rush. Replay any stage to find the cleanest line within par.

MADE TO LAST
- 120 handcrafted stages across 12 chapters, each with exactly one correct route.
- Difficulty that deepens slowly, like ink spreading on paper.
- Every gate carries a color and a Japanese glyph, so the logic reads clearly for color-blind players.

A QUIET AESTHETIC
Sumi-e brushwork, aged paper, lamplight and vermilion seals. Built to feel like a three-minute painting you solve on your commute.

ShimenSoka is free to play. A single optional purchase removes ads — that is all.
