Sudoku, kept simple and satisfying.
Sudoku musuby is a clean, friendly sudoku app for a quick game every day.
● Every puzzle is generated, every puzzle has one answer
Puzzles are created inside the app. Each one is checked to have exactly one solution before it is shown, so you can always solve it by logic alone – never by guessing. You will never run out of puzzles.
● Honest difficulty
Difficulty is not based on how many clues are given, but on the techniques you need to solve the puzzle. Easy puzzles need only basic moves; Expert puzzles require advanced techniques such as X-Wing.
● Four levels
Easy, Normal, Hard and Expert – from your first sudoku to a real challenge.
● Built for comfortable play
・3-2-1 countdown to start
・Pencil notes for candidates
・Mistakes shown in red (can be turned off)
・Undo one step at a time
・Auto-save: pause anytime and continue later
・Optional mistake limit (game ends after 5 mistakes)
● Hints from the wheel
Each puzzle comes with 3 free hints. When they run out, spin the wheel and get 1–3 more, decided by luck.
● Track your stats
Per difficulty: games played, wins, win rate, streak, best time, average time and perfect wins (no mistakes, no hints).
● Works offline
The game runs fully offline – even in airplane mode.
● Privacy
The app itself collects no personal information. All your data stays on your device.
Whether you love sudoku or are just starting out – enjoy a little brain workout whenever you have a spare moment.
