The KenKen puzzle game is today’s online brain games highlight.

KenKen was invented in 2004 by a Japanese math teacher named Tetsuya Miyamoto. The game was originally intended as a learning tool to improve both the math and reasoning skills of his students.

“Ken” means wisdom in Japanese, therefore KenKen means “wisdom squared”.

The game is very similar to the layout and rules of Sudoku, but KenKen adds the requirement of solving simple math problems in order to complete the puzzle.

KenKen puzzles come in 3×3 all the way up to 9×9 grid sizes.

The rules of KenKen are simple. For a 4×4 grid puzzle the rules are as follows:

  1. Every box in the grid will contain a number 1~4
  2. Every row and column will contain the numbers 1~4 only once.
  3. The numbers in each heavily outlined set of squares, called cages, must combine (in any order) to produce the target number shown in the top corner using the mathematical operation indicated.
