## What is Kurodoko?

Love Sudoku or brain-teasing puzzle games? Discover Kuromasu now – the ultimate logic challenge from Japan! No guessing required; just use pure logical thinking to conquer every level.

Your mission is to light up the board by correctly placing Black and White cells:

Each number on the board represents the total number of White cells it can "see" horizontally and vertically.

Black cells act as "walls" that block the line of sight.

Note: Black cells cannot be placed next to each other, and all White cells must be seamlessly connected!

 Diverse levels: Thousands of puzzles ranging from basic (5x5) for beginners to massive boards for experts.
 Intuitive tutorial: Built-in interactive step-by-step tutorial helps you master the rules in just 1 minute.
 Minimalist UI & Dark Mode: Modern, eye-friendly interface that lets you focus 100% on solving the puzzle without distractions.
 Play offline anytime: No Wi-Fi required, featuring smooth auto-save functionality.

Download Kurodoko today to keep your brain sharp!
