KenKen is a mathematical grid puzzle developed by Japanese math teacher Tetsuya Miyamoto, as an instruction-free method of training the brain. In 2008, Bob Fuhrer, a Chappaqua resident and owner of the company Nextoy brought the puzzles to the attention of Michael Harvey, an editor of The Times (London). Harvey, impressed with what he calls its “depth and magnitude”, arranged for publication of such puzzles, starting in March 2008. The New York Times followed suit and KenKen now appears in more than 100 newspapers in the United States, as well as numerous international publications. The name derives from ken, the Japanese word for cleverness.
