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!
