Conceptis launched KenDoku: Learning math will never be the same!Tuesday, November 18, 2008
Conceptis announced KenDoku, a new number-logic puzzle that uses addition, subtraction, multiplication and division in creative and uncommon ways. Aiming to change the way people relate to basic mathematics, KenDoku is promised to provide hours of mind boggling fun while brain-training and improving one's math skills at the same time.
KenDoku renamed to CalcuDoku
In mid December 2008, following request by Nextoy LLC, co-owner of KENKEN™ trademark worldwide and owner of Ken-Doku™ trademark in the USA, Conceptis renamed KenDoku to CalcuDoku. Read more here
KenDoku release includes three variants; SingleOp; with addition or multiplication; DualOp with addition and subtraction or multiplication and division; and QuadOp with addition, subtraction, multiplication and division. All variants, initially available in print format, come in six sizes from 4x4 to 9x9 and in seven carefully controlled difficulty levels - from ultra easy to very hard.
First dedicated book titled Ken-Doku
According to Jochen Vetter, Conceptis’ Number-Logic Product Manager, an easy KenDoku puzzle may take only one minute to solve while a very hard one can provide several hours of challenge and fun. KenDoku puzzles are already available in Conceptis' publisher Download Center and the first KenDoku book is scheduled to be released by Sterling Publishing in January 2009. Titled Ken-Doku (ISBN-13: 9781402765834) Sterling’s book is already available for pre-order on barnesandnoble.com
More about KenDoku
KenDoku puzzles by Conceptis, also known as Square Wisdon, CanCan and MinuPlu, are based on the same rules of KenKen™, a successful educational puzzle invented by Tetsuya Miyamoto in Japan as an instruction-free brain-training method.
KenDoku rules are very simple and require a little basic math coupled with a lot of interesting logic. Each Conceptis KenDoku puzzle consists of a grid containing blocks surrounded by bold lines. The object is to fill all empty squares so that the numbers 1 to N (where N is the number of rows or columns in the grid) appear exactly once in each row and column. In addition, the numbers in each block produce the result shown in the top-left corner of the block according to the math operation appearing on the top of the grid.
