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.
