The game has a “correct/incorrect” solving mode which I am not a fan of, I’d prefer to solve a puzzle and check at the end to see if it’s solved and allow myself to find mistakes while solving instead of just immediately getting “BRAWP WRONG”. However if you do get a correct tile and then later accidentally note or input another number, your correct answer is lost and you take another incorrect answer, if this system is going to stay, correct answers need to be locked in and unchanging. Some of these things are changeable in options, they should not be set like this to teach/learn sudoku, it’s unintuitive and promotes winning over making mistakes and learning, especially the 3 mistake limit. Next thinking about solving tools, only one set of notes that gets very in the way and is locked to a grid orientation, especially on mobile that makes some sense but I would still love a highlight tool or a way to mark cells in more than one way with the same set of numbers, it’s far easier to keep track of patterns and observations that way. Also there’s way too many ads, you will never solve a puzzle without being interrupted at least one time. Removing ads is $5 and without the other issues I have with the app I’d be happy to pay, until then they’re asking more than most apps for something I can just close and re open the app to skip. That or stop selling your space to the worst possible mobile ads that are intrusive and you can’t exit out of them.
