Fun with Math, One 'Small' Issue
Dec 21, 2017 The puzzles are a fun combination of simple math and sudoku; great learning tool for young mathematicians. I would happily give it 5 stars if they'd fix one small bug. When you solve the last puzzle in a series and click 'Next Puzzle' to continue on to the 1st puzzle in the next higher series; the highest integer in the series is not displayed in the list of available numbers to put in a cell. You have to exit to the menu and then choose the higher series to see all necessary numbers. Cheers!more -
Great challenge
Jun 3, 2017 Have tried several of these type and this is definitely the choice for me. It allows a user friendly way to add possible numbers and erase if desired. Being able to pick the level and match to your skill level right from the start was a big aid, not having to work through countless levels to get to one that matches your ability. I am going to go to a pro level in the future, but for a free app, this is definitely one that will stay on my iPad. Well done.more -
Puzzled by "Best Time So Far"
Sep 11, 2017 I definitely enjoy this game. But I'm puzzled that every puzzle I finish is messaged with "...beat time so far!" --no matter how long it's taken me!more -
Great game! Found small bug.
Feb 20, 2018 I recommend this game to anyone who likes kenken style puzzles. I did notice that as I played the final 4x4 and pressed “next game”, the first 5x5 showed up, but I still had only the numbers 1-4 to pick from at the bottom. And it would also be nice if the numbers were a bit higher on the screen. Sometimes I hit the “hint” when I was just trying to pick “1”.more -
Doesn't save work when it crashes
Mar 11, 2019 The app crashes not infrequently. Or even if it's just running in the background and closes. When you go back in, your work is gone. Some of the puzzles take quite a long time, so this is a problem. Also, some of the puzzles are easy and some are impossibly hard, with no apparent logic or order.more

Annotations not working - is this a scam app to get you to "Go Pro?"
Oct 11, 2017 Fingers crossed this is a temporary glitch, but the annotations function does not exist/work on this app (just downloaded to my phone). Checked instructions on "how to play", however the icon just isn't appearing. Only undo and redo. Tried holding down a square - still nothing. Even bought the $1.99 Pro - again nothing. Unfortunately I don't play without making occasional annotations, so without that function I can't give an accurate rating on how the rest of the app works. Hope it gets fixed soon.more -
Good for entry level, bad beyond
Jul 14, 2018 The game provides no method of saving progress. This means that levels hard enough to not be done in 30 ish minutes become an exercise not in ken ken skill, but in begging the app not to reset for some asinine reason. Quick switch to respond to a text? 2 hours of progress gone. Habitually pocket your phone and hit the screen off button? Kiss your game good bye as you’re greeted with the loading screen and crushing frustration.more -
Love puzzles but HATE video ad
May 6, 2018 This could be a great 5 star app if it wasn’t for a terribly annoying video add that plays upon successful completion of a puzzle. You cannot turn it off. I turned off sound effects but the video “ad” or whatever it is still plays. I hope the developer listens and gets rid of that dumb video.more -
Great but certain bugs make it entirely frustrating and unusable.
Oct 23, 2018 If you close the app and try and come back, it’s either frozen and needs to be closed and restarted or just automatically goes to the home screen on its own. Which i could handle except that theres no way to save the game. Very hard to do the bigger boardsmore -
Horrible Interface
Jun 16, 2016 The interface for marking possible values is terrible. We need to be able to select more than one square and mark all of them at once. Even marking one square with several candidates is too hard. Please fix this. Otherwise, the app is good and the game is fun.more

Fun and Relaxing
Jan 16, 2019 Game is wonderful fun and calms me at the end of the day. I spend too much on the check function where you can see if the numbers you’ve entered so far are correct, but without it I’d lose interest.more -
Great Thinking Math Game
Apr 30, 2017 Excellent for all levels. Puzzles range from extremely easy to extremely difficult. A great feature is you can redo a puzzle to beat your own best time. I love it!more -

Mar 26, 2018 I really do love this puzzle. Is there anyway to earn more helps? That would be really great. Thanksmore -

Small puzzles are fun, large are impossible due to time
Feb 2, 2020 This game needs a save mechanism. There’s also a bug when you graduate to higher dimensions. The set of numbers to use is missing the top number. For example, choose the last 4x4 puzzle and complete it. Choose next and you hover the first 5x5 puzzle yet the numbers you can use are 1 2 3 4. There’s no 5!more -
THE PROBLEM IS...
Feb 21, 2018 I love the puzzles but I HATE that the app doesn’t save my puzzle if I close out of the app or the app crashes (which it does). Sometimes the puzzles take an hour to complete and I’d like to be able to work on it at different times throughout the day. Fix that and you get 5 stars. I took away 2 stars for that sole reason.more -
Progress lost, even without closing the app
Aug 6, 2020 The game is great. Love it. But it is super frustrating when I spend 40-50 minutes on a puzzle, make sure NOT to close the app, go back to it the next day, and my progress is lost.more -
God but annoying
Mar 14, 2018 I would likely have given it a 5 except for the fact that the “Would you like to rate this game” screen is so frequent as to become annoying very quickly.more

The Ads are Ridiculous
Dec 31, 2016 Instead this game and like the game play and interface, but you've gotta be kidding me with these ads! After EVERY puzzle you get a full screen ad that can't be dismissed! You have to follow the ad, dismiss whatever it opens and go back and reopen the game. Absurd. Uninstalled after five minutes and three puzzles.more -
10 seconds of gameplay, 30 seconds of ads
Nov 30, 2017 Egregious ad placement make this a nightmare to play. You can't skip ahead to normal difficulty puzzles so you're stuck playing through 15 second stages and sitting through 30-60 seconds of ads between each stage. Terrible shameful cash grab.more -
Pro version is a rip off
Nov 15, 2016 I paid $2 to unlock undo/redo. Players cannot make notes of possible or impossible variables. Game does not autosave on close - you will lose all your work if you close without manually saving. Very frustrating player experience.more
What’s Groovy
I absolutely love this game! I have spent hours on it doing one puzzle after another. However, I do think there are some things that need improvement. When I finish all of the puzzles for one number, I have to go back to the menu in order to be able to select all the numbers for the next puzzle (If I go straight from a 4x4 puzzle to a 5x5 puzzle, there is no option to put 5 on). The hints and checks buttons are really close to the numbers buttons, so there are times where I’ll be going really fast and accidentally slip on one of the hint/check buttons. If they were in the upper corner or where the reverse buttons were, I don’t think this would be a problem.

What’s Subpar
Revised. Lost another puzzle of work. Was about 80% complete. Did not turn off my iPad. Just put to sleep. Go back to the game and find a blank puzzle. The developer website has no mention of this game. Play the game but don't support the developer. Poor poor interface.
I love kenken and these are good puzzles. The problem is that if you stop a puzzle and come back to it, all your previous work is gone. You have a blank puzzle. I've taken to taking screen shots each time I stop a puzzle. I can't sit and an 8X8 or 9X9 puzzle in one sitting. I've got work to do.
Please fix this problem.

Downloaded for my 4th grader
But finding that I'm quite addicted as well! Great way to work your mind. My 9-year-old likes to challenge me on it. Great bonding tool for us. -
Perfect for Number lovers!!
This is such a wonderful game and playing it on an app makes it so much easier. I'm sure everyone who loves numbers will love this. -
Outstanding
Great app. Many outstanding and challenging games. So far I am doing the starter pack but will be sure to buy the paid version, the games are so good. -
Best option online.
Hated the others. This one is difficult but a beginner can learn and advance far better. Thanks! -
Very well done. Worth it.
I started on the NYT ken ken page on the PC, but I like this one on my phone. It seems to catch my fat fingers a little better.

In progress puzzles aren’t saved.
There really needs to be the capability to save puzzles. It would be even better for capability to save progress across multiple devices. -
FOR THE LOVE OF GOD, FIX THIS BUG
Other people have mentioned this, but it is SO INFURIATING to be nearly done with a puzzle, minimize the app to check a text, and when you come back the app is restarting. It’s almost enough to delete the app entirely! -
10 seconds of gameplay, 30 seconds of ads
Egregious ad placement make this a nightmare to play. You can't skip ahead to normal difficulty puzzles so you're stuck playing through 15 second stages and sitting through 30-60 seconds of ads between each stage. Terrible shameful cash grab. -
Decent interface, terrible puzzles
All of the puzzles are incredibly easy, there are no difficult ones. I guess you get what you pay for.
-
Good for entry level, bad beyond
The game provides no method of saving progress. This means that levels hard enough to not be done in 30 ish minutes become an exercise not in ken ken skill, but in begging the app not to reset for some asinine reason. Quick switch to respond to a text? 2 hours of progress gone. Habitually pocket your phone and hit the screen off button? Kiss your game good bye as you’re greeted with the loading screen and crushing frustration. -
Love puzzles but HATE video ad
This could be a great 5 star app if it wasn’t for a terribly annoying video add that plays upon successful completion of a puzzle. You cannot turn it off. I turned off sound effects but the video “ad” or whatever it is still plays. I hope the developer listens and gets rid of that dumb video. -
Horrible Interface
The interface for marking possible values is terrible. We need to be able to select more than one square and mark all of them at once. Even marking one square with several candidates is too hard. Please fix this. Otherwise, the app is good and the game is fun. -
Hints too close to the numbers.
Also, the ❌ and ✅ are too small. I wasted most of my hints on easy puzzles because if I didn't press the number just right I would use a hint when I already knew what the solution was. -
Crash Doku
App crashes and freezes when call or text comes and you loose all that you worked for.....need to get the bugs out. Don’t buy packs cause you’ll lose your hints when crashes. -
Resets puzzle all the time
If you switch to another app for more than a few minutes, the puzzle you’re on will reset and you’ll lose all your progress. -
In progress puzzles aren’t saved.
There really needs to be the capability to save puzzles. It would be even better for capability to save progress across multiple devices. -
Puzzles don't save properly
Puzzles are great, but if you pause them and leave the app, your progress disappears! -
Could be so much better
Love the game but UI is clumsy at best and losing the current game on exit is just wrong
-
Annotations not working - is this a scam app to get you to "Go Pro?"
Fingers crossed this is a temporary glitch, but the annotations function does not exist/work on this app (just downloaded to my phone). Checked instructions on "how to play", however the icon just isn't appearing. Only undo and redo. Tried holding down a square - still nothing. Even bought the $1.99 Pro - again nothing. Unfortunately I don't play without making occasional annotations, so without that function I can't give an accurate rating on how the rest of the app works. Hope it gets fixed soon. -
Great but certain bugs make it entirely frustrating and unusable.
If you close the app and try and come back, it’s either frozen and needs to be closed and restarted or just automatically goes to the home screen on its own. Which i could handle except that theres no way to save the game. Very hard to do the bigger boards -
The Ads are Ridiculous
Instead this game and like the game play and interface, but you've gotta be kidding me with these ads! After EVERY puzzle you get a full screen ad that can't be dismissed! You have to follow the ad, dismiss whatever it opens and go back and reopen the game. Absurd. Uninstalled after five minutes and three puzzles. -
10 seconds of gameplay, 30 seconds of ads
Egregious ad placement make this a nightmare to play. You can't skip ahead to normal difficulty puzzles so you're stuck playing through 15 second stages and sitting through 30-60 seconds of ads between each stage. Terrible shameful cash grab. -
Pro version is a rip off
I paid $2 to unlock undo/redo. Players cannot make notes of possible or impossible variables. Game does not autosave on close - you will lose all your work if you close without manually saving. Very frustrating player experience. -
Full Screen Ads Stuck on Screen Every Puzzle
Have to restart after each puzzle because an ad pops up which takes up the full screen and can't be dismissed without rebooting the app entirely. Uninstalled after 3 puzzles. -
FOR THE LOVE OF GOD, FIX THIS BUG

SO SICK OF LOSING ALL MY WORK!!! PLEASE FIX!!!
Working on bigger puzzle grids takes more than one sitting. Mathdoku randomly resets back to a blank puzzle grid and you lose all the work you did! There must be a way to fix this!!!!!! -
Undolvable puzzle found
Puzzle addict pack>6x6> puzzle 002. No way you get 15 without using 6,5,4. And after filling in the 5s in single boxes, the 5 repeats in 15+ addition box.
