KenKen is touted as being yoga for your mind and the puzzle that makes you smarter. KenKen, a grid-based numerical puzzle, uses basic maths operations (addition, subtraction, multiplication and division) while challenging logic and problem-solving skills. When players think ahead, plan the next move and consider all the possible outcomes, the better they'll get at the game and the more they'll sharpen their mind.
Acclaimed Japanese mathematics instructor Tetsuya Miyamoto developed KenKen in 2004 with the goal of improving his students' math and logic skills. This understandable, fun and challenging puzzle quickly became a favourite leisure activity for all ages throughout Japan and then for millions of players worldwide. Now it's carried in the New York Times, Los Angeles Times, Chicago Tribune, The Times of London, Scholastic classroom magazines and more.
