Ken Ken is a puzzle game. This game increases our mathematical and logical ability. This game is invented by Japanese teacher named as Tetsuya Miyamoto in 2004. This game is also known as KenDocu, MathDocu, CaluDoku. This game is published in near about 40 newspapers over the world. I got to know about this game from Sunday Times of India.
This game is played in various grids like 3X3, 4X4, 5X5, 6X6, 7X7, 8X8 and 9X9.
If you are playing 5X5 then you can fill number from 1 to 5 only.
Rules are very simple
1. Each row and column contains exactly one number i.e. no number is repeated in row or column.
2. Each bold shaded group of cells called cage. There is a target number written in upper left corner in one cell with a mathematical operators (+, -, *, /). You have to use that mathematical operator and you have to get that target number. You can repeat the number is the cage but not in row or column.
Enjoy the playing...
