The Origins
The KenKen puzzle was introduced by Japanese math teacher Tetsuya Miyamoto in 2004. The KenKen puzzle comes in the form of a grid of squares commonly in the dimensions of 4 squares by 4 squares, 5 squares by 5 squares, 6 by 6, 7 by 7, and 8×8, and 9×9. The larger the grid, the more difficult the puzzle.

The Rules
In the grid, groups of squares form “cages” indicated by their bold outlines. In the upper-left of each cage, is a number with a mathematical operation. You have to put digits in the squares such that the mathematical operation of those digits results in that number. The digits can be in any order. But you can not have a repeat of a digit in any row or column of the larger grid.

And you can only use digits up to the size of the grid. For example, if your grid is a 5×5 grid, then you can only use the digits 1, 2, 3, 4, 5 to fill into the squares.
