KenKen

KenKen™ is a mathematical and logical puzzle loosely similar to sudoku. It was invented by a Japanese mathematics teacher Tetsuya Miyamoto as an 'instruction-free' method of training the brain and was later published in The Times in March 2008.

The objective is to fill a grid in with the digits 1 through 6 such that:

  • Each row contains exactly one of each digit
  • Each column contains exactly one of each digit
  • Each bold-outlined group of cells contains digits which achieve the specified result using the specified mathematical operation: addition (+), subtraction (-), multiplication (x), and division (). Unlike Killer sudoku, digits may repeat within a group.
