3 stars: It's very good and enjoyable but when you make mistakes it immediately alert you, therefore takes a bit of the fun.
4 stars: 4 star because I would like the program to tell me how many mistakes I made as soon as I finish the game. Other than that change, it would be a 5 star.
4 stars: Really good, only bad thing is I hit the hints button with a resting finger, annoying when you don't want a hint, could it be moved from the edge of screen?
5 stars: Fantastic mind boggling games only thing that has to be improved is after filling all 9 numbers in the nine grids ,ie 9 × 9, the number 9 should change colour or disappear from the selection board of numbers Well thank you so much for your quick Response Really delighted to play the game. Keep improving 😍😍😍. Would be great if you could add some scoring to it. It could be Challenging to have Scores
4 stars: Good app, gameplay is easy and some of the features like auto clearing notes is great. One recommendation would be to have the undo button also undo the hint feature. It's annoying to be in the middle of a diabolical and accidentally get a hint - ruins the game. Would be 5 stars with that thanks
5 stars: Great, easy and very intuitive navigation options!
4 stars: Very functional version. My only gripe is that you can't turn hints off and I often accidentally touch the hints icon with a trailing little finger, which then proceeds to fill in an outstanding cell. This can't be undone, unfortunately...
