The different features of the game:

The game mode

If you tap on a field that has already been filled in, the playing fields that contain the same number will be highlighted in color throughout the game.

If you tap on an empty field, the row and column in which the field is located as well as the selected field will be highlighted.

If you get stuck, you can automatically fill in the selected field with the correct number by pressing the “hint” key.

With “clr” you can delete entries from a field.

If you have lost track of incorrect entries, you can restart the current game with “restart” or select a new game with the “new” button.

If you have filled out the game completely, but entered errors, these errors will be highlighted in color. You have the option to delete the errors with “clr” and continue the game or select a new game.

If you interrupt an unfinished game, the game status including notes will be saved. Next time you open the game, you can continue exactly where you left off.

There are four different levels of difficulty:
easy, medium, difficult and hard.

The memo mode

In memo mode you can write notes in empty fields or delete notes that have already been entered, just like on a printed Sudoku.

If “autofill memos on long click” is activated in settings, the possible input numbers are written into the field as a note when you long tap on an empty field.

If “autoupdate memos on new input” is activated in settings, entering a number in an empty field will automatically update the affected notes.

Settings

On the settings page you will find a description of the game and its functions under the info button “i”.

When you start the game for the first time, you have the option to choose from 16 different languages. You can change this choice at any time in settings.

You can choose between four different color themes.

Enable or disable “autofill memos on long click” and “autoupdate memos on new input”.
