Ken Ken
Ken Ken is a number puzzle from Japan. It consists of an n × n playing field, in which boxes are grouped into different areas by thicker borders. Numbers from 1 to n must now be entered in the playing field according to the rules.
The Japanese name is Kashikoku naru Puzzle ( Japanese 賢 く な る パ ズ ル Kashikoku naru pazuru , German 'puzzle to become wiser / cleverer' ). Ken is the Sino-Japanese reading instead of the Japanese reading kashiko (i) of the first character.
origin
It was developed by the tutor Tetsuya Miyamoto for his students and has been distributed by the Japanese publisher Gakken since 2006 . The Sudoku puzzle served as a template.
regulate
Ken Ken follows similar rules as Sudoku . Each number can only appear once per row and column. In contrast to Sudoku , there are no numbers given. Instead, the playing field is divided into areas that are marked with a calculation result and a basic arithmetic function ( addition , subtraction , multiplication or division ). The numbers within each range must produce the specified result with the specified basic arithmetic function. The order of the operands is not fixed. For example, in a division field, both the dividend and the divisor can be on the left or right.
Legal
The name Ken Ken is trademarked in many countries. This is why this type of puzzle is called differently in most publications; for example: Minuplu, Basic, KenDoku, MathDoku, CalcuDoku or Yukendo .
