2020-Mar-27: I've been working on a new set of Skyscraper puzzles, and you can download a preview sampler here (just in case you're bored, stuck inside for some reason, and like a really challenging puzzle). Enjoy!

Free Beginner KenKen Puzzles

Here are hundreds of free KenKen puzzles suitable for printing. These Inkies do not use multiplication and division (click here for those). Inkies have the same rules as KenKen® the puzzles created by Tetsuya Miyamoto. They are also called Mathdoku, Calcudoku, and Web Kendoku. Each Inky puzzle has only one unique solution.

Instructions

Fill in the blank squares so that each row and each column contain all of the digits 1 thru 4 (or whatever the size of the puzzle is).

The heavy lines indicate areas (called cages) that contain groups of numbers that can be combined (in any order) to produce the result shown in the cage, with the indicated math operation (plus or minus).

Numbers in cages may repeat, as long as they are not in the same row or column.

Take a look at the answers page if you get stuck!
