Kenken V Sudoku

Kenken V Sudoku

Is KenKen the new Sudoku? An introduction to the new game!

Will Kenken the latest craze from Japan, live up to its expectations, hailed as
the new Sudoku?

So you reckon you can handle a “Fiendish” Sudoku? Well meet the new kid on the puzzle block, which is set to rock the UK puzzling world KenKen.


First published in the times newspaper in March KenKen has only recently migrated to the UK. KenKen was created by Tetsuya Miyamoto a Japanese mathematics teacher who created the problem to be addictive and educational. Each contains a “trick, a discovery – a story”

How to Play

  • Digits from one to six must appear in every column and row but may not be repeated in the same column or row
  • Within the large square there are several bold boxes
  • Target number in the left hand corner must be worked out using digits in the blocks and the calculation symbol provided


The solutions for this KenKen puzzle are included further on in this article, so stop reading now and have a go.

KenKen v Sudoku

The two puzzles are very different and will appeal to different users. KenKen is far more mathematical than Sudoku, which contains logic alone. You could substitute the numbers in Sudoku for symbols. However this mathematical element may be where KenKen’s strengths lie. Mr Miyamoto says that the trial and error and arithmetic elements involved are essential, breaking away from the fact cramming learning techniques employed today. Will this help prepare us to deal with real life problems?


So having tried KenKen for yourself do you think it set to take Sudoku by storm?

I don’t know if it’s endorphins or what, but I get a “rush” when I do puzzles. The latest one I’m hooked on is KenKen. I don’t think it’s possible that things like KenKen and crosswords don’t help your brain stay fit.

I’ve made a video about how to start solving a 9×9 KenKen in which the operation signs are not given.
