Best Sudoku App For Me But ...

NEW UPDATE: May 18, 2015 - I see nothing that indicates that a new version has been released, downloaded, and installed. However, sometime in the last couple of weeks, this app began working PERFECTLY again, making it my goto Sudoku game once more. Go figure?

UPDATE: Below is my original review of this once great app, but things have changed ... Oh how they have changed. Months ago, simple functions, like accessing my photos and, once accessed, loading the selected photo, began to take 30 seconds or more to occur. NOW, this app doesn't work at all. It has become useless. Shame on the developer for allowing this to happen.


This is my favorite sudoku app and I spend at least 30 mins with it (and often more) every day, but a truly superb additional feature, for advanced users, would be the ability to MASS CHANGE NOTES FROM ANY COLOR TO ANY OTHER COLOR. Meaning, one could specify, "please turn all red notes to green" for example. This would be a simple function to add and would save me between 20% and 40% of my time every game, allowing me that much more time to actually play the game. Please ... Thanks, Jay

Getting much better

After a disasterous update a few weeks ago, many of the bugs are gone. The puzzle grid is square, and the number keys are reasonably sized again. One feature is still lost: when you've completed a number, the key remains enabled. It used to disable and grey-out numbers when they were all filled in. This was a handy visual aid. I also wish there was some way to "light up" all the instances of a particular number. That's a feature that's available in a lot of other sudoku apps.

Nice app, works fine on my 6+

I'm sorry to hear so many people below having trouble with this app. It has crashed on me assigning a tag before but otherwise am able to scan puzzles and okay them through very nicely. It also does just fine detecting when you put an erroneous number in. Works well on my 6+!
