Sudoku ‪″‬ 4+

It’s beautifully designed, the developers are very responsive, and it’s simply wonderful to not have to pay for a subscription.

If I have one complaint it’s this: I keep finding that certain puzzles don’t quite match up to their levels. Difficult-level puzzles will actually be Hard, Medium will be Difficult, Hard will be Difficult, etc. This doesn’t happen all the time—maybe like 5-10% of the puzzles I get—but it’s kind of frustrating. The developers deserve no blame though: I’m guessing the algorithm used to create the puzzles probably needs to be tweaked a little, and that’s not always easily accomplished.

Please don’t let this detract from this review though, because I adore this app, and use it all the time.

The game is well designed with one exception. When you fill in a number for a box as an answer, rather than a note of a possible solution for a box, it will automatically erase all conflicting notes on other boxes. So if I put “9,” for example in a box, it will automatically erase all other notes where 9 might be an answer in the same rows and columns. That is good! But it’s very easy to put down a number accidentally as an answer, when you only intend to list it as a note of possible answers. When you do that, and I promise you will accidentally do that more than once, a bunch of your notes on other boxes are automatically erased. If you don’t catch it right away, it will ruin that game.

I still love this app! I play it all the time--I've grown bored with most every other game (or finished all levels--or plateaued!). Last update is great--very easy to use. I can almost always finish the "Evil" level puzzles. UPDATE: I still play this once every day! Keeps my mind working. If you've never tried Sudoku puzzles, the different levels lead you to mastery in no time at all! UPDATE ON MY UPDATE: I have no idea when I first downloaded this app. I have played most of the games out there…get tired of them…delete them…then a couple of years download it again. I NEVER get tired of this. I have three degrees in science, math, and medicine, and not much holds my interest. This app does. Try it…I think you’ll like it.
