MathDoku

I think this is the best thing I've downloaded, ever. It never gets old, because there are infinite puzzles (as far as I know? I've played at least 800 since I got the app about 18 months ago). Don't think the difficulty ratings scale perfectly, but that does mean the game makes you keep learning.

I play all the time on this app. Puzzles range from 4 x 4 to 9 x 9. There are an unlimited number of puzzles that can be created. One problem is that all puzzles required all four math operations. Other apps have the option of choosing which operations to use, but those apps cost more.

Totally addicted. App performs well, no crashes yet! I like that it automatically saves when I close out of the app and resumes when I come back to it. Thanks!

I love the app. In fact, I'm giving it 5 stars despite the game statistics now a black screen (with what may be the stats bunched up on a tiny cube in top left corner). Can you put a link to previous version? There was really nothing wrong with that one...

Simple and fun. Can create various puzzle size and difficulty. Great time waster.

No puzzles give even one number to help get started. All puzzles are trial and error instead of pure logic.

Ok app!

Without a bunch of permissions it doesn't need. This is how you do a game.

I had this app on an old phone and I used to be able to play archived games (I'd try beating puzzles in previously gave up on). How do I do that in this version? Thanks

Requires no special privs, loads quickly, takes some brain power. Recommend.

Did the archive functionality get removed?

can't get enough of it - very customizable. get it! so far I've spent 2170 hours playing the 7x7 level and still love it!

Can play 1 game after install but after that pressing new game does nothing. Was fine b4 the update earlier in November. Please revert!

This is a great game. I wish they would bring back the option to save boards though.

Doesn't want too many permission, simple, lightweight and best. Thank you.

I enjoy the dynamics between the differing totals and results possible at the differing sizes and skill levels. Just going up a size category changes the game as you have to incorporate another number into your mental factorization. It has been my go-to casual game for over a year.

The interface is great. If you don't like swipe then you can change it in the settings (I like the using the buttons so I turn it off). This is by far the best mathdoku game out there.

Such a good game for free without ads is really appreciated. I'll definitely recommend this game.

Make the board as large as possible on the screen - buttons don't need to be that big!

Good game

Very good

Ok app!

Was already great, now even better

I have played this game constantly since I found it soon after its release. The developer made some significant UI changes but then was receptive to our requests to make the old interface available as an option. It's now back to its position at the top of my favorites list.

Very addictive, nicely implemented

Best puzzle game I have played.

Great

Math puzzle

No puzzles give even one number to help get started. All puzzles are trial and error instead of pure logic.

Bad design

Great game, fun & challenging!

The statistics for cheating are good. I don't care for the statistics tied to 'maybes'. It's annoying because I get to play in short bursts and it keeps my place in complex puzzles.

Was perfect until the last update now uninstalling and looking elsewhere.

This is the best free Kenken/Mathdoku app out there.

Mode switches from Normal to Maybe randomly. Cannot reset error message.

Fun time killer

Was great until this update. Keypad doesnt appear on my samsung galaxy pop... Pl bring d old version back...

I'm so bummed, this was my favorite game and the app was awesome! Unfortunately, I just downloaded the updated version and not only can I not change the screen orientation, but I can't play at all--the number pad isn't there. Super sad, I shouldn't have tried to update. I even uninstalled and reinstalled as someone recommended with no luck.
