I've been playing sudoku using this iOS game for years, but very sporadically. Yet I've always loved it. The interface is perfect in that it doesnt provide cheats or shortcuts, but does help to keep track of things that are otherwise not the fun part of solving a sudoku (for instance removing all the scratch notes for a digit once you've solved something that eliminates the possibility of them being in other squares. Lately I have been playing more and I had the urge to try different tile sets. And for the first time playing this game I experienced an ad (I think they normally only play after you have won a game and then elect to start a new one... I'm usually too spent). The ad played and within 5 seconds the sudoku call game creators had it set to let me skip it. And get right back to playing. Then it dawned on me how much I appreciated not getting ads thrown at me left and right, not having them interrupt me at any time during a game, and even on the rare occasions when they did play, being able to skip. Bought it immediately for $4.99. Too cheap. I wish I could show the developers my appreciation more. Add a tip jar! And thank you!

For the most part I love everything about this game. I have one big issue that really affects gameplay. The scoring is done by multiplying a number that lowers as the time counts on to the number put into the empty box. The issue is how many numbers are missing and which numbers are missing. On expert it could be 23-26 numbers given. So having three extra numbers gone gives you a higher score then having more numbers to start with. And it depends on how many of each number you already have. If you have most of the 9’s and zero 1’s your score is going to be dramatically lower than if you had most of the 1’s and zero 9’s. So, the majority of the score is not coming from how fast or well you’re solving the puzzle, but rather which numbers are missing in that round. I have to start over whenever I have a board with too many high numbers and too few low numbers. That means I can never have a play streak because I don’t want to have a low score and waste my time with the board I know I can’t do well with. On average, I probably play one out of every six boards. I just wish the scoring was different because it shouldn’t rely entirely on what numbers they choose are missing, instead of speed and skill level. It’s not that some of the boards on expert are easier than the others, it’s just that if most The nines are there and most the ones are not, filling in a one multiplied by the time number that gives you your score is worth a lot less then putting a nine multiplied by the same. Rather than a point value based on the missing numbers they could just make filling in a blank number worth the same no matter which of the numbers are missing.

I've loved this App and playing Sudoku for years! I've played over 8000 games but tonight I sadly could not finish what will possibly be my last attempted game! Used to be the ads appeared between finishing one game and starting the next. This is acceptable. Now, however, ads come up every 15-30 seconds. This makes the game unplayable and certainly no longer enjoyable. It's been a nice run but sadly will be ending if this does not get rectified! ☹️Update: Intrusive ads isdues seem to be resolved but some recent update(s) now appears to have altered and drastically slowed down the game play. Now when selecting an empty cell it takes the game a very noticeable delay to highlight already filled in cells in the same horizonal row and same vertical column as the selected empty cell. It now takes a very noticeable pause for that cell to be filled in with your chosen number. Not sure if this was intended to improve the player's user experience but it certainly doesn't. In fact, it degrades it. Can you please just leave the gameplay as it's been for so long? That consistency of user experience is what made this app stand apart from many others! Makes me wonder if the developers are implementing changes because they can and seem cool from a coding perspective but they aren't getting any honest feedback from players before they publish updates? 🤷‍♂️

I have been playing this game pretty regularly over the years and the latest update has really ruined the game. It is now glitchy and slow to respond to key actions in the game. This slows down the game and takes the enjoyment out of it. I am keeping this game downloaded with the hope the developers fix these issues. It’s been a couple months and there hasn’t been any noticeable improvements when I check back. I will give it a month or two more but it the issues are not resolved this game will go in the trash heap. Too bad since I enjoyed the game before the updates that ruined it.Update 22 Aug 2025: I tried the game out again after an extended pause and it looks like all the annoying bugs that ruined the game have been fixed. It is back to what it used to be. Fun game play without the glitches. I have seen some reviews mentioning annoying ads in the middle of game play but I have not seen this. The ads have consistently been between games/matches. This is how it has been the entire time I have played the game.
