Sudoku — A Clean Daily Sudoku With Four Difficulties

Info

Sudoku is a clean daily sudoku game: one fresh board every day with streaks, four difficulties (Easy to Expert) where every board has a unique solution, notes, hints, undo and auto-save. Works offline, no sign-up. 9 languages.

Sudoku With Everything You Need and Nothing You Don’t

I wanted a daily sudoku I could solve with my morning coffee — so I built one. Instead of flashy effects, it carries only the features sudoku players actually use.

• 📅 Daily puzzle — a fresh board opens every day, and solving it keeps your streak alive
• 🎚️ Four difficulties — Easy · Normal · Hard · Expert. Every board has exactly one solution
• ✏️ Notes, undo and erase — pencil in candidates as you go, and a hint fills one correct cell when you’re stuck
• 🏆 Records — mistake count, best time per difficulty and your last 20 games
• 🔢 Game numbers — every board gets a six-digit number, so you can replay it or challenge a friend to the exact same puzzle
• 💾 Continue anytime — your game is always auto-saved

It works fully offline with no sign-up or login, and supports 9 languages.
