## Description

Calm, ad-free sudoku with large, clear numbers, gentle hints, daily puzzles, and offline play. No ads now or later.

No ads. Not now, not later. The free experience is calm by design.

WHAT'S INSIDE
• Daily Puzzle: one fresh sudoku every day
• Four difficulty levels: Easy, Medium, Hard, and Expert with Premium

DESIGNED FOR COMFORT
Calm Sudoku is made to be readable in low light, gentle on the eyes, and forgiving when you tap the wrong cell. The board uses generous spacing, clear contrast, and large digits so you can focus on the puzzle instead of the interface.
