Will Shortz does KenKen

Back in April, I put up a post about KenKen puzzles when they first started appearing on the Times Online site.  Now Will Shortz is jumping on the KenKen bandwagon and he’s created a short video to introduce the puzzle to America.  The puzzle Will does in this video is very simple and uses only addition.  Still, it’s clear that some of the harder puzzles that he mentions involve other arithmetic operations.

With Will Shortz behind it, you can expect to start seeing KenKen puzzles in newspapers soon.  He’s also planning to realease a few KenKen books in October.

KenKen Puzzles

A while back there was a post on Passion for Puzzles about a new kind of puzzle called KenKen puzzles.  The puzzle was featured on the Times Online site where a few puzzles were printed along with an article about the puzzles’ creator Tetsuya Miyamoto.  To be honest, I only skimmed the article.  It seemed to be more about the creator’s teaching philosophy than about puzzles.

KenKen puzzles are a variation of killer sudokus.  The layout is exactly the same.  The only difference is that the groups of boxes have not only a number, which in killer sudoku would represent the sum of the numbers in the boxes, but they also contain an arithmetic operator which tells you what to do with the numbers.  They need not only be sums.  They can be differences, products, or quotients.

Enjoy!
