【Step-by-Step Hints That Explain the Reasoning】

Hints do more than simply reveal the answer.

First, they show you where to look.
Next, they explain how the possible numbers can be narrowed down.
Finally, they show you which number belongs in the cell.

Each time you use a hint, you receive a little more information, so you can keep thinking for yourself while getting the help you need.

From basic solving techniques to more advanced candidate-based strategies, explanatory hints are available for every puzzle in the app.

【Mistakes Are Never Punished】

Choosing the wrong number will not trigger harsh warnings or a game over.

Instead, the app gently encourages you to try another number.

There are no limits on mistakes and no time pressure, so you can take your time and try again as often as you like.

【1,000 Carefully Selected Puzzles】

There are three difficulty levels:

・Easy: 300 puzzles
・Normal: 350 puzzles
・Hard: 350 puzzles

Every puzzle has been carefully checked so you can play with confidence.

Start with Easy if you are new to Sudoku, or move up to Hard when you are ready for a greater challenge.

【Pick Up Right Where You Left Off】

Your current puzzle and entered numbers are saved automatically.

Even if you close the app, you can continue from the same board the next time you open it.

【Keep a Sudoku Diary】

The days when you complete a puzzle are recorded on a calendar.

You can look back on:

・When you played
・How many puzzles you completed
・Which difficulty levels you played
・How many hints you used

You can also leave a short note for each day or replay puzzles you completed in the past.

There are no streaks or rankings to pressure you.

Your Sudoku Diary is simply a place to look back on your progress at your own pace.

【Celebrate with Fireworks】

When you complete a puzzle, fireworks and confetti celebrate your success.

Each completed puzzle comes with a cheerful little moment of accomplishment.
