Sudoku Extreme: Classic Number

This is probably the most feature-packed sudoku I’ve found on iOS with tons of quality-of-life settings like auto-note at the start and highlighting cells with a chosen number/note. Long-press to auto-fill is pretty good, and I just found long-press to select number for single-touch-auto-fills. The nitpicks I have are technological in nature though. Long-press (and probably even regular press) should allow haptic feedback, probably as a toggle; if I’m playing for speed then I can’t see if a cell is filled from long-pressing because my finger covers the entire cell so vibrating the phone would let me know the long-press activated. I also have an issue with animation blocking the ability to touch immediately. I’ve found one legit bug though. With animation on, if you fill a cell (definitely with long-press, almost certainly with the normal way) and you cancel the animation super early (e.g. you accidentally slide your finger to the next cell too quickly from a long-press) the triggers of follow-up actions like erasing the number from the necessary notes don’t fire. I currently can’t think of any other extras I’d like to have in a sudoku game, this one seems to have them all covered!

This is a great implementation of the game. The UI is fluid and intuitive, the score keeping is fun, and the hints help with deduction techniques. I have two small requests: 1) can there be a preference to turn off the animation? Towards the end game of a puzzle the animation slows down a rapid-fire solving of cells as their possibilities whittle down to one. 2) for Hard (and beyond) levels, can we have an ‘auto-fill’ button for cells with only one possibility? My fat fingers have occasionally hit the wrong number filling in those cells and they’re counted as a mistake against me. Keep up the great work! This variant of the game is my favorite on iOS.

The UI is wonderful and clean, as well as instantly intuitive for Sudoku fans. The app has many novel features not seen elsewhere, such as pre-filled notes. It's clean and offers easy change of themes, which is nice- It's nice to see a developer recognize not everyone would like their first choice of colors. Edit: Apparently there has been an option added to toggle swiping notes off. That's a great addition, but it still doesn't totally alleviate the ease with which you can accidentally enter an incorrect number. Aside from toggling into note mode until ready to make an entry, that is still an issue. At least now my problem is incorrect notes, not accidental incorrect entries. To the Dev: I still love this game, but I consider issue where you can accidentally enter a wrong answer to still be fairly large.

Love the color schemes and overall interface design. The haptic feedback is wonderful. Definitely my favorite Sudoku app. There are two downsides: 1. The UX is not fast. When I click on a cell, it doesn't immediately select the cell and I can't immediately place a number. This slows down my fill speed. 2. When a number is fully used, the app should not allow it to be placed again. I've had multiple times when I accidentally hit a grayed out number which then counts as a mistake (usually when I'm trying to fill cells quickly toward the end of a game). This can definitely help reduce accidental mistakes. Keep up the good work

If you play (too much) Sudoku like me, you will absolutely love this app. Tons of customization and the auto fill notes is a different take on the game. One note to anyone who plays rapidly: immediately turn off animations. If you don’t, you will get quickly irritated by the fact that the notes don’t remove themselves in time (otherwise you have to wait for the animations to play out before notes on the selected number are removed). It will cause you to make a lot of unnecessary mistakes. Once they are off, this game is perfect!
