Sudoku 17

In this App, you can test your Sudoku solving skills on Sudokus with just 17 starting values. 17 is the minimum number of starting values required for a unique solution!

Even though all Sudokus have just 17 starting values, we still offer four different difficulty levels. The Sudokus in the lowest difficulty level are relatively easy to solve, even though you get just a few starting values. On the other hand, the Sudokus in the highest difficulty level are extremely difficult and might be almost impossible to solve!

Pick your desired difficulty level, and slowly work your way towards the most difficult Sudokus there exist!

The App does not bother you with a full screen Ad whenever you finish a Sudoku or want to go to a different menu. We know most Sudoku Apps do use these ads, so we are hoping you appreciate this! (If you do want to support us, there is a button in the settings menu that will make you watch an Ad)

The App contains multiple tools to help you solving the Sudokus. All of these can be tweaked to your personal preferences in the settings menu.
For example, you can:
- Use multiple colours for the note values
- Automatically remove notes that are no longer possible
- Highlight impossible values you enter. E.g. two times the same value in one row
- Fill empty cells with note values of the remaining possibilities in that cell
- Play full screen (no status bar)
- Enter your own Sudokus and solve them in the App
