For a 3x3 puzzle, use the numbers 1-3; for a 4x4 puzzle, fill in with numbers 1-4; for a 5x5 puzzle, use the numbers 1-5, and so on. Do not repeat a number in any row or column. Complete rules are available in the app for your convenience.

A Little KenKen History: KENKEN was developed in 2004 by (no, not two guys named Ken) acclaimed Japanese mathematics educator Tetsuya Miyamoto. His goal was to improve his students’ math and logic skills. And what better tool than a puzzle? So he developed one that would be understandable, fun, and challenging for people of all ages and skill levels. Most importantly, he wanted the puzzle to encourage independent thinking, emphasizing logic, reasoning, concentration, and perseverance. His puzzles immediately met with unbelievable success and are now used the world over for kids, adults and the elderly. KenKen has proven to be one of the world's best brain exercises for people of all ages, and can now be found in over 200 publications worldwide.

Customer Reviews

Nearly perfect.

First of all, Ken Ken is an amazing puzzle game. Much more robust and engaging than Sudoku, with which it shares some similarities. This app does a great job bringing Ken Ken to iOS with a wide variety of board sizes and difficulties to choose from. Better yet, its design brings a lot of functionality to make playing more fun and less tedious by automatically removing possible tile solutions once they become impossible.

I feel that 50 puzzles for free is more than fair and the prices for removing ads and unlocking more puzzles are reasonable. The only knock I have for this game is the fact purchases are locked to one device and not tied to an account. So purchases made on the iPad do not allow me to play more games on my iPhone.

Great stress relief. Play without a hitch

It says a lot about our rhythm of life when playing ken ken turns out to be a stress relief. I downloaded this to "race" my kids on two or three other smart devices. But I also recommended it to several of my employees to wake up the brain or just chill. I told them to forget the clock. To my surprise I see them playing in the break room intently looking for clues and actually feeling happy when they complete the puzzle. It gives them closure in a successful way. So that motivates them to go back to work when results are not immediately revealed. The app is easy to learn and play. Great job.

Can't Connect

Love these puzzles but I have just bought a new iPad and I can't get any puzzles. I keep trying to buy puzzles and am told that the transaction went through but then I get a notice that the server is not responding. This has gone on for three days. I am now puzzle less. I am surprised that all the puzzles I previously bought did not transfer over. My other puzzles generally transfer seamlessly. By the way I just tried to give this one star and it would not register. As I hit again it came up with three stars. Curious....
