About this game

Based on the same rules as the hit KenKen(tm) game, as printed in the New York Times and The Times (uk).

Related to Sudoko, but with a mathematical twist - use the arithmetic challenges in each cage to help solve the puzzle.

Ratings and reviews

I love this game and have been playing it for quite some time now. I like the feature that you can hide operators and make it more difficult. My only issue is that I updated it a week ago, and the puzzle board got smaller and the copy button disappeared. The copy button was quite helpful for pasting "maybe" numbers easily. I can still live without it, but I don't know why the puzzle screen got smaller. Anyway to make it bigger as before? Hard to play 9*9 puzzles even on big screen phones.

I've been playing Mathdoku (also known as Kenken - a name protected by copyright) for years, through a series of phones and tablets, and on paper as well. This is a great, crash-free, ad-free app, with enty of variations. More complex than Sudoku, with a whole range of math and logic strategies to figure out and employ. As easy - or as difficult - as you choose!

The new update makes this game unplayable. Played all the time before but the new numbers input ring makes things so time consuming and distracing I will find a new game. Don't bother reading any reviews before the update because all the ones after say the same things and they're not good. Edit: the ring was removed and the game is fixed. 5 stars again!
