ABOUT THE GAME KENKEN
MathDoku is a mathematical and logical puzzle based on KenKen and loosely similar to sudoku.
Puzzles can be solved by combining the four main mathematical functions of addition, subtraction, multiplication and division. To train the brain the puzzles are offered without any instruction. There are important keys to be found but no fixed starting place and no method of progression that can be learned as a strategy. The brain is forced to dart between competing theories. It’s impossible to solve puzzles without the scientific process of trial and error and that’s the rationale behind these puzzles.
KenKen was invented by a Japanese mathematics teacher Tetsuya Miyamoto and introduced to The Times via Robert Fuhrer of Nextoy and Chess Champion Dr. David Levy and recognized for its depth and magnitude by The Times features editor, Mr. Michael Harvey. KenKen brain training puzzles are a trademark of Nextoy, LLC. Toy inventor Robert Fuhrer, founder of Nextoy, discovered KenKen (aka KEN-KEN) in Japan as the original books published by educational publisher Gakken Co., Ltd. as Kashikoku naru Puzzle, and has been instrumental in introducing them to the western world.

This KenKen adventure started in late November 2008.
My girlfriend found the game KenKen in a local newspaper. Having both been fans of sudoku (although she was significantly better than me), we immediately took a liking and interest to this new type of game. We played KenKen games as often as we could and always looked for the local newspaper to play another game, especially when we were at coffee shops where newspapers were plentiful and many times free.
This interest rapidly grew into an obsession. Newspaper versions were not enough. A quick search of the interwebs yielded few results and proved ineffective as KenKen printable versions burned a lot of consumables like paper, ink, and electricity (we’re trying to live a little greener). To ease the addiction, we set out to make our own interactive, online version. And in less than a month the initial site, http://www.webkendoku.com/, was born. Shortly afterwards, in February 2009, we were notified by Robert Fuhrer that the use of “kendoku” in the domain name infringed on their trademark of “KenDoKu “. To avoid any legal disputes, WebKendoku.com closed as we transitioned to this new site. We apologize for the inconvenience and hope you enjoy this site and the game as much as we do.
But, we could not have possibly done it alone.
