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.
OBJECTIVE
Depending on the size of the grid, fill-in the table with the appropriate numbers where:
- 4x4 tables use only numbers 1-4
- 6x6 tables use only numbers 1-6
- 8x8 tables use only numbers 1-8
- Each row contains exactly one of each digit with no repeats
- Each column contains exactly one of each digit with no repeats
- Each bold-outlined group of cells contains a clue with a number and symbol. The symbol represents the mathematical operation and the number represents the result.
- For example, if the clue for a group of 2 blocks is "7+", some possible answers could be 1+6, 3+4, or 2+5
HOW TO PLAY
- Review the table and each cell
- When you've identified the value of a cell, click in the cell and type your answer
- If you get stuck, you can click the hint button
- Continue answering to fill-in the table
- You can change an answer by clicking in the cell and deleting your old answer
- If you mess up, you can click the start over button the clear the table
- When you're done, click the check answer button to see if you got it right
- Click the new game button if you wanna play another game
EXAMPLE
The example below uses only addition to simplify things.
"1" - single block are always the clue
"2 & 1"- sum of 3, 1's cannot repeat in the first row
"3 & 1" - 3 is the last number in the first column, plus 1 equals the clue of 4
"2 & 3" - 2 is the last number in the bottom row, plus 3 equals the clue of 5
"3 & 2" - last number in the first and second rows and the middle column, and add up to the clue
ABOUT US
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.
First and foremost, I want to give credit and thank my wonderful and amazing girlfriend. Thank you for your patience and understanding, I know there were a lot of late nights. And thank you for your loving support, without you this would not have been possible.
I Love You!
