MathDoku Extended for Android
A simple delight. Rarely do I consider an app or location worth the 5 stars.
Fun diversion, it works well and has few ads.
Free, unlimited games, multiple sizes and difficulties, and NO extraneous permissions!
Great puzzle game that refines problem solving and rapid arithmetic skills.
Playing for about a year. Only complaint is lost archive.
Best version I have come across, have been playing this for over 2 years
Bug report: As soon as you finish a game, it disappears from the screen, and you can't even access your past games in the archives. Update: They fixed this the next update after I reported it.
I only play hardest 9x9. 1. Give option to auto fill entire board at start of game with maybes. (All 9 or digitcalc ... All 9 would be preferred by me) 2. Place maybes in 3x3 grid. 3. Double tap or long press green square for auto fill when only one maybe left. Also: 10x10? 11x11? … NxN? (I would like to try a 25x25 or something insane like that ... Would tax the hell out of my ability to factor numbers in my head, fun!) All in all, my favorite amongst the versions in play store ...
Great way to exercise your brain, but it needs two changes. 1. There should be a"Contact us" button in the help menu. 2. It keeps statistics in the form of a bar graph with games on the x-axis and time used to solve on the y-axis. It keeps a different bar graph for each grid size, but each grid size has different degrees of difficulty, and the degrees of difficulty are all combined in the same bar graph for each grid size. This doesn't make sense.
At last - an even better adaptation of Ben's original game that was then ruined for so many fervent players. Great improvements and very friendly developer who welcomes comments
Tried all the others. This one let's you pick the size of the board AND a difficulty level for each. 9x9 and 4/5 difficulty is very very hard.

This is the only kenken type app I know of that has the calculator built in. This is a fantastic game. Definitely a must for all fans of this type of game. I cannot praise this app enough! Well designed, well executed. Just perfect in every way. The inclusion of the calculator, which is just fine on its own, makes checking up so much easier. I'd gladly pay for this app.
Yeah.

You don't understand my issue. I WANT to lose my archive when I uninstall and reinstall Mathdoku Extended. By losing my archive, I would get a new bar graph. The way you have it now, once I have played 250 games at a particular level, the bar graph never changes for that level of difficulty. Please either 1. Let me lose my archive when I uninstall and reinstall the game, 2. Give me a button to erase my archive, or 3. Make the bar graph show the most recent 250 games. I prefer choice 2 or choice 3.
