I’m trying to learn sudoku

I have never played sudoku before and I decided to try to learn it. I got this app and chose easy mode. i read the rules and started playing. It was discouraging to see that it only let me make 3 mistakes 😔. you should make some sort of free play/practice board where people don’t get a limited number of mistakes (but they don’t get stars/points for playing). it would be helpful for beginners like me who don’t really care about stars/points at first they just want to learn how to play. also, the ads and their placement is really annoying. the banner-style ads that are at the bottom while you play are in the way. if i try to click a number and i press too low, i click an ad! i know you have to put ads to get money but please put the banner style ones at the top of the playing board where people will see them but not click them on accident. also, the video ads are really long and there are LOTS of them. i really don’t want to pay FIVE DOLLARS to get rid of them. other than those complaints i have, the app is very nice and neat. i like being able to change the board color for free. the erasing sound is very nice. i haven’t tried any challenges yet because i am on my first puzzle, but they sound interesting. the hints are terrific! it suggests where to put a number and explains why it put it there. i’m glad i decided to learn how to play sudoku! 😀

Solid app, these features would make it even better

Worth the $5 for sure. If you play this game often, buy it and support the developers. Love the UI with the ability to quickly change the colors. Also the app is fast it doesn’t glitch or lag, allowing me to play fast. Some other apps are laggy and it slows me down. Please make the following changes: 1. The HINT button needs to be renamed. It is not a “hint” it just reveals the square. Call it REVEAL. 2. Add a setting to allow paying users to remove the HINT button. I keep accidentally tapping it 3. Create an actual HINT button that gives a hint 4. Make the “tournaments” real, with players competing against each other instead of a scoreboard full of fake users and fake scores 5. Prevent users from doing unlimited HINTS or reveals in tournament games. 6. This is BIG one that would make things so much easier. Please add a calendar selection feature so that players can easily browse to past daily puzzles. Currently players must swipe one month at a time. If I have completed the past two years worth of puzzles and want to play some older ones, I would have to swipe 24 times to get to the puzzles that I want to play! Take a look at the NYT Games crossword app and the way they handle the calendar.

Bad timing for commercials

I recently got into Sudoku again quite a few years ago I dappled in it now I have seven apps for different makers of the sudoku game. I’m gonna narrow it down to two or three that I like the most and I’m playing them back to back playing a couple games in each one until I figure out what I do and don’t like so originally I like this one the most because it was the first one I downloaded in this recent journey of getting back into it but what I’ve came to realize is it gives the ads at all the wrong times you’re just getting on a roll and it congratulates you if you finish a number or a cell or a block whatever and how it congratulates you by giving you an ad it’ll be like a cute little emoji congratulations way to go you’re doing great and then Bam you gonna add I understand these apps to be free have to have ads but it’s just all bad timing. Maybe if you mess up or something give you an ad give you an ad when you finish the game or when you start a new game something like that, I’ll try and keep track of what the other ones do but I’ve played the other ones all a few times and I was not annoyed with the ad so this must have the most ones out of the seven that I have and it’s super annoying because you just get on a roll, you got numbers in your head what you’re gonna play next and then you gotta wait for an ad and you lose it all in your mindso if it wasn’t for that, I would probably give it a five star
