Sudoku Extreme: Classic Number

At least try to implement a decent algorithm, if you try to milk users with that wannabe app. Not even worth 1*

I get more points if I don't use the pencil notations... but I have to subscribe to take them away! How can I decide if I am unable to take her for a test run?

I wish this app would save unfinished games so I could go back later and try to solve them. Once a new game is selected there is no history of previously unsolved games. The hints only reveal a square instead of offering a suggestion for the next possible move. The medium puzzles are waaaaay too hard considering the easy puzzles are a cake walk. I complement you on the dark theme. I would suggest two rows for the candidates at the bottom of the puzzle, it is too easy to press an incorrect digit. Also, a box around them looks nice. (See the NYT sudoku app) It would also be nice to have an on/off toggle for the automatic pencil candidates (also see NYT app)

Ever since the update its way too easy. The features are great and I used to love this app. Was hoping it would go back to being challenging after some feedback from others. Anyone else feel the same? You have to pay to get the harder levels.

I’m enjoying this version of sudoku. Most of the features that are needed in a sudoku app are here. The hard puzzles are VERY challenging. I appreciate the automated pencil mark feature very much. The highlights are useful (though I do find some color themes to lack sufficient contrast). I have a few suggestions for improvement: The “coloring” technique is not an option on this app and it could be a very useful addition. I sometimes use a solver to learn more about the extremely difficult techniques. It would be nice to be able to export the board in its current solve state to make that easier. Or, maybe the hint option can give a tutorial on the technique used to move you ahead, rather than just exposing an answer.

Great game other then why can’t change any settings, should be able to change some of the settings. Totally star’s ⭐️⭐️

Unless you’re looking for a version of sudoku that’s already filled in and doesn’t require any thought, you will have to pay. Some apps require you to progress though the tiers to unlock the next difficulty but this one doesn’t offer that. Beginner is the only free option

Best sudoku app and developer

The limitations of the game are overly cumbersome. All hints are filled in and it records incorrect answers if you try to leave a cell without selecting a number. There are an impressive amount of options available but you are required to purchase the app to get anything offered. This is not something I would recommend to a young adult that is trying to enjoy a few minutes of quiet or anyone else that is looking to relax. There are other similar apps out there that better put together.

Edit: I think the scoring system is broken at a certain point. Still a 5 star game, but until I can see the specific calculations for each of my highest scores, I cannot remove this. I read the scoring template and it holds true up to a certain point, then you’re capped So many ways to customize this game! Was not expecting this. First app I’ve purchased in a long time. Great job! I am curious about the scoring system because my friend and I cannot increase our score anymore. It feels like there is a cap.
