First impression. Not as slick as the one I'm trying to replace. May take a bit of getting used to. Definitely needs option to add pencilled in possible solutions. Ability to colour in order to check "simple colouring" solutions would help too. Overall, I'm not overly keen on the UI.

Great looking, sleek Sudok with no ads. The difficulties in this game are harder than in other games, at least in my experience, as I actually had to learn some more advanced Sudoku tactics to solve a board. 5/5 with one minor complaint/feature suggestion: After filling in notes on the board and then writing a number, the notes that cannot be true anymore are not automatically removed. While this is not a necessary feature, it would be nice if this was implemented.

This is much the best sudoku, I have found. No annoying ads, no silly gimmicks just Sudoku with notes possible and lots of levels of game. Just one fault: I found the background far too light, and the figures a bit too small for me. There needs to be more contrast between the notes and correct figures. But I think this game much better than others I've tried.

Like that you can set up your own puzzles. will use this due to this feature since most apps don't have this. Wish the undo button would undo the note numbers you put in, instead of just undoing the solved numbers. Also, when leaving the app and returning without closing, it saves my created game but not the penciled in numbers-- which is a bigger pain,l. I can't leave a puzzle now unless I have enough filled in to not be bothered by redoing the fill ins.

I would love to give a 5* review since this is the only app I found that doesnt have ads but: 1.The unlock criteria for higher difficulties has a bug, I started with medium and after 3 finished sudokus the hard one would not unlock. 2."Undo" only reverts last number not last candidate and also deletes all candidates in that cell instead of restoring it to previous state. 3.No "redo" button 4.No option to unselect cells to have a clean view 5.Pausing game and exiting app deletes all candidates!!

Very clean. No ads. Inbuilt puzzles as well as ability to scan sudokus using camera and ability to manually create a sudoku puzzle. To support the developers, I'm willing to buy the app if the developers are thinking of releasing a paid version. Suggestions: 1. Auto delete redundant notes as other boxes are filled.

Very cool that it does not have ads, but it needs some improvements. When I make a mistake it immediately tells me that it was wrong, revealing information I would otherwise not have. Also when I continue a game another time, all my notes are gone.

Good app but numbers need to be bolder font as it's not so clear on smart phone screen. Also the notes numerals are really feint. But there's also a bug - when you leave the app and return to resume a puzzle, all the previous notes are lost! Fix these for 5* !
