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.

Review 2.0: I've been playing this version of Sudoku for several months now, and I want to thank the app developers for providing a version of the game for the adults! No funny animals, no storybook themes, no frantic distractions! Just a great app with plenty of boards to challenge you. For the greatest variety of challenge levels and no ads to distract you, spring for the "pay-to-play" version. It does not disappoint. Every player, from the beginner to a master's level player, will find a grid to their liking. Enjoy enjoy!

Review 3.0: As I said before! Simply, the best.

Review 4.0: I’m doing “medium” level grids, and am enjoying the challenge. Keep up the good work! As I said before, simply, the best!
