Master Of Sudoku

What could be innovative on another game of Sudoku?

Perhaps the three different game modes:

- Classic

- Emoji

- Colors

Perhaps the three levels of difficulty:

- Easy

- Intermediate

- Difficult

Perhaps the ability to customize the layout with predefined themes, and modify the list of Emoji and colors you want to us

Perhaps settings, saved games and a useful zoom?

... I'd say it's up to you.
