## Description

■ One puzzle a day — DayDoku, a minimalist sudoku game built around a daily habit.

DayDoku is a clean, focused sudoku app designed for one quick puzzle a day. Wake up your brain, build a streak, and enjoy the quiet satisfaction of showing up.

■ Why I made this
I'm a developer who loves playing sudoku. I got tired of how aggressive ads were in the apps I used — they kept interrupting the very thing I came to do. So I built the app I wanted to use. DayDoku makes one promise: you will never see an ad while you're solving a puzzle.

■ Ads, kept minimal
• No ads while you're playing — the promise
• No interstitials, no video ads
• A single small banner only on menu screens (home, stats, settings, result, help)
• Non-personalized ads to limit tracking

■ A new challenge every day
Every midnight, one Today's Challenge unlocks for every player worldwide. Difficulty steps up across the week:
• Monday: Beginner
• Tuesday: Easy
• Wednesday: Medium
• Thursday: Hard
• Friday: Expert
• Saturday & Sunday: Master

■ Streak rewards
Finish the daily challenge day after day, and DayDoku gives you more allowed mistakes and hints per game.
• 3 days: +1 mistake
• 7 days: +1 hint
• 14 / 30 / 60 / 100 days: more bonuses unlock
Miss a day and the streak resets — so keep showing up.

■ Free Mode in six difficulties
Play whenever you want. Pick from Beginner, Easy, Medium, Hard, Expert, and Master to match your mood.

■ A clean playing experience
• Notes (pencil marks) for candidate numbers
• Hints fill in one correct cell
• Undo / Redo
• Pause, auto-save, and resume any time
• Daily and Free Mode are saved in separate slots — starting one never overwrites the other

■ Light and fast
• Fully offline — works without internet
• Minimal design with full dark-mode support
• Korean and English

■ Who it's for
• Anyone looking for a quiet brain workout on the commute or before bed
• Habit-builders who want a tiny daily ritual that sticks
• Sudoku fans who hate ads getting in the way of play

Today's puzzle is waiting. Start your streak.
