Project 2.1

The KenKen puzzle is an arithmetical puzzle that ties together sets, magic squares, and suduko-type puzzles.


Each of these puzzles uses the set consisting of the first n counting numbers. The rules are simple:

  • Fill in the grid with the numbers 1 to without repeating a number in any row or column.
  • The outlined portions are called cages and these portions must combine, in any order, to produce the given number using the given operation.
  • A number may be repeated in a cage as long as it is not in the same row or column. Try solving the following KenKen puzzle.
