One of best Sudoku apps

I’m updating my review. Still an awesome sudoku app, and I’ve played almost all the apps out there. Some of the new features keep me hooked. For example, the events is great. Sometimes my brain gets tired of always playing expert or nightmare levels so it’s nice to play some easy levels. Plus, it has a clear goal for me to work towards.

And also, cross math is an interesting concept. It’s great for my son to practice his math, and I never would’ve found out without playing this app.

(Previous review) I’ve been playing Sudoku for a long time, and this is one of the best mobile apps for Sudoku. A few things, it has a very clean and easy to use interface. When I click a number, it highlights the corresponding row, column and square, so I can easily scan the board to find other potential numbers.

Also, when I write notes and tap a number, all notes with that number are also a different color, so it’s easy to see which cells have that number, and I can start doing deductions more easily.

Finally, it has a hint feature that explains how a cell came to a number, which is better than other apps I’ve seen that just directly tell you the answer. Overall, there are many advanced features for the seasoned Sudoku player, but also great for newer players. Would highly recommend this app.

Here for Cross Math

As someone who loves math (to a point of majoring in it in college), I love the cross math portion of this app. People who keep saying the cross math puzzles don't add up, double-check your solutions. So far I've done 94 puzzles and never had any issues about the math not adding up. Only reason I'm not giving this a full five stars is that it tends to be slow on my phone and a lot of times I have to restart the app or pause and resume intermittently just because it keeps lagging when I try to solve the puzzles but the timer is working just fine (my competitive self doesn't like that lol).
8/28 EDIT: Since the most recent update, my cross math time records for all levels except for levels 1-4 got wiped out. I'm talking about 102 frigging levels here. Cross math also became ridiculously easy as well. Oh and level 127 DOES have a math error and is keeping me from moving on to the next level. So this is where I stop playing, I guess. Not to mention the fact that the app still lags when played for more than a few minutes (either in cross math mode or sudoku mode)... This update just made it worse and is such a disappointment.

Developer Response ,

Hi, we greatly apologize for such an error in Cross Math. We have urgently fixed this issue in Version 2.5.3. Please kindly upgrade to this new version and continue playing Cross Math. We have also forwarded your feedback on the difficulty level of Cross Math and the lagging issue to our team and will continue to optimize our game to deliver a better gaming experience. Please feel free to reach us at with any other feedback. Thanks a lot for your support and patience. Have a great day! :-) - Cathy

Best Sudoku Experience

I tried a handful of sudoku apps and found this one to have the best combination of supporting speedy play, clearly highlighting relevant numbers without giving away solutions, and providing clear hints to help players improve.

Devs I do have one request – the fact that Nightmare difficult puzzles sometimes require hints that simply fill in the correct value for a call makes it hard for me to feel like I can work on those puzzles logically since I can’t think through how those are calculated, so if there’s some way to show the underlying logic there it would be much appreciated. Thank you for adding the difficulty setting though!
