## What is Trilumin?

Three ways to think. Trilumin bundles three classic logic puzzles — Sudoku, Gokigen (a Slitherlink-style loop puzzle), and Futoshiki (inequality number placement) — behind one calm, minimal design with light, dark, and sepia themes.

Track your personal best times and see your world rank on the global leaderboard for every game and difficulty. Limited hints, pencil-mark notes, undo, and mistake tracking keep it a serious puzzler's tool, not a casual time-waster.

Trilumin is free to play and includes optional in-app purchases. Some screens display ads.

Three puzzles. One place to think clearly.

### 1.1.0 — 2026-08-31

This update brings a calmer home screen soundtrack, a distinct win chime, and error sounds alongside vibration on mistakes. 

Set a new personal best and see your world rank right in the win screen. A new vibration toggle lets you turn haptics off entirely.

Futoshiki's inequality signs are now clearly visible between cells. The numpad and toolbar now stretch to fill the screen on phones for easier reach.
