Love this Sudoku app. It’s my go to app when I want to play. I have two others but this one seem to work the sudoku algorithm just right. Having said all that, there’s still a few things that need fixing. Like others have noted, the game clock should not start until the game starts. Having it start while it’s making you watch an add is dishonest. And just today I’ve found I can’t mute the sound when the ad comes on. I thought it was my iPhone so I rebooted it but I still can’t mute the sound. And the ads always ignore your sound settings and blast themselves full volume. This means you can’t use it anywhere you want.

After trying nearly all of the free sudoku apps, I have rested on this one as my favorite for actual game play. The puzzles are well-designed, and even the hard and expert puzzles are actually solve-able without notes or hints if you’re good enough. That said, it is not without its faults. I don’t mind ads, but they are a little excessive, (and it is a bit jarring to see somewhat threatening NRA ads constantly). And frustrating that the clock starts on your game while you are still in the ad. The timer works fine on individual games, but the app does not accurately compile data for you to see if you are beating your own times. The “winner” screen is visually and functionally buggy and pretty useless. Despite all of this, I still play it daily for the good games. Though I imagine there will be a day when one too many NRA ads send me over the edge and I delete it forever and go buy a sudoku book.

I have tried many digital sudoku games and this is the best I found. If there were a way to gray out numbers that i am working on when taping on the number in column and row so that the user can see more clearly where that number would go in the other it would enhance digital game play greatly.

MANY (maybe all) of the issues I read about in these reviews before trying the game have been corrected by settings to leave things as is or do the opposite. For example you can turn off the “Disable invalid note buttons” so no more filtering of just the valid numbers for the selected cell. Some of the settings are worded awkwardly but that’s because they retained the existing functionality, which overall is the norm. Also, during games the ads appear in their own designated space and not full screen so they don’t interrupt the game. And I absolutely LOVE that I can access older Daily Challenge games so no sweat if I miss a day.I’d like to see a Pause and a Restart button.Having the numbers in 2 rows is a bit awkward for me; I’d prefer all in one row so 5 and 6 are right next to each other.They really should offer an option to pay some small amount for no ads. Now that the issues have been resolved, users would pay a few bucks for that.
