KenKen Puzzles are created by Japanese educator Tetsuya Miyamoto set to be the successor to Sudoku.
KenKen puzzles can be solved by combining the four main mathematical functions of addition, subtraction, multiplication and division. To train the brain the puzzles are offered without any instruction. There are important keys to be found but no fixed starting place and no method of progression that can be learnt as a strategy. The brain is forced to dart between competing theories. It’s impossible to solve KenKen puzzles without the scientific process of trial and error and that’s the rational behind KenKen puzzles.
