Spring 2022

The Krazydad Discord Community is a new place where you can talk to me, and meet other people who are interested in puzzles. A great place to report problems or mistakes with this website, suggest new features, help me brainstorm and test out new puzzles, get periodic announcements from me, or discuss other deep thoughts. Maybe I'll see you there!

Free KenKen Puzzles

Here are hundreds of free KenKen puzzles suitable for printing. Inkies have the same rules as KenKen® the puzzles created by Tetsuya Miyamoto. They are also called Calcudoku, Mathdoku, and Web Kendoku. Each Inky puzzle has only one unique solution.

The Beginner puzzles listed below use only addition and subtraction, and are a good math activity for kids.

If you're an advanced KenKen solver looking for a tough new challenge, check out my Krypto Inkies!

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. For example, 8× means you can multiply the values together to produce 8.

Note that I use a slash (/) to indicate division instead of the traditional symbol (÷) to avoid confusion with the plus sign (+).

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!
