Sudoku - Classic Sudoku Games

I’ve been doing Sudoku puzzles since I was in high school for math homework and it has become increasingly difficult to find an app that truly challenges me anymore. The “expert” level truly will force you to use your entire store of logical reasoning to complete and it’s so satisfying when you finally get it! This level goes far beyond the basic rules of sudoku. Some complain that the app’s pencil feature doesn’t erase possibilities when you fill in a permanent number and that there isn’t an option to erase once you’ve filled one in, but I actually find that this makes the app’s overall experience much more like doing a puzzle in real life (on paper, imagine that) and forces me to pay more attention when filling in cells - then it’s great when I realize I forgot to erase the pencilled-in number that is no longer a possibility and I sometimes end up solving a cell due to that when I get stuck! Overall, great app, simply designed, challenging puzzles and an extremely minimal ad experience (if you even notice the ads at all - you’ll never have to worry about one popping up mid-puzzle or anything horrible like that).

… with ads being unobtrusive. Only change I would make is to have a diminishing number of mistakes allowed as the difficulty levels increase, and to make the limits clear, alongside the errors made thus far, and the elapsed time. For the competitive, some stats on aggregate performance against a particular puzzle would be nice. And the “master” level is far too easy. Recommended.

I’m new here. Tried a version where the finished numbers disappear from the list below.i liked that. But I appreciate this being a stand-alone app (not part of a pack of games).

When you're finished with a number it doesn't disappear from the number list like every single sudoku game I've ever played. Very strange. It makes things confusing and you end up double guessing if you finished using a number. After winning the game, it tends to freeze up on the continue screen. Deleted the game, have to find a better one

A nicely designed soduko app. But if trying to change from or to possible number in the lower left corner it does not work, then the app is missing a screen rotation option. The puzzles on “hardest” level are fairly easy. Ohh and to avoid the lame fake commercials, use airplane mode..
