Customer Reviews

Works really well

The pencil marks are easy and quick to use. The hints and tutorials are very helpful, they make it easy to learn new techniques progressively and gradually. I like the way it explains techniques step by step. The grading of the games by difficulty is good, though occasionally games seem to be a bit harder or easier than the rated grade. It is useful and encouraging to see the % rating of the score compared with other users, it is a good way of measuring your progress in gaining skill. The cell colour coding tool is helpful in tracing chains but it can be tricky to turn it off without inadvertently changing to colouring the pencil marks. The advertisements are unobtrusive and don't spoil the game. Over the past few years I have tried a few other Sudoku apps but I keep coming back to this one, it is the best.

Star of my phone

I have had this app on a number of phones and it simply works. No muss no fuss, easy to use, I learnt to play sudoku on this app and I now play daily to unwind. I have tried others out of curiosity and always come back to this. Totally love this app.

One of the best Sudoku apps

I play daily and still learning.

One small suggestion if I may. I would find it useful, when placing pencil marks, to have the row, column and square containing a given number, to be softly highlighted when each number is selected. Maybe a future version?
