KenKen puzzles, also known as KenDoku, are grid-based logic puzzles similar to Sudoku, are designed to improve students’ calculation and logical thinking skills.

Basic Rules and Structure

Grid Size: KenKen puzzles come in various sizes, typically from 3×3 to 9×9 grids. The grid size determines the range of numbers to be used. For example, a 4×4 grid uses numbers 1 through 4.

Objective: Fill the grid with numbers such that no number repeats in any row or column.

Cages: The grid is divided into heavily outlined regions called “cages.” Each cage has a target number and a mathematical operation (addition, subtraction, multiplication etc). The numbers within each cage must combine (in any order) to achieve the target number using the specified operation.

Solving Techniques

Basic Arithmetic: Use basic addition, subtraction, multiplication, and division to combine numbers within a cage to match the target number.

Logical Deduction: Determine possible numbers for each cell by eliminating numbers already used in the same row or column.

Trial and Error: In some cases, you might need to try different combinations and backtrack if you encounter contradictions.

Cage Constraints: Use the constraints provided by the cages to limit possible number combinations.


Educational Value: Enhances arithmetic skills. Encourages logical reasoning and problem-solving.

Engagement: Offers a fun and challenging way to practice math. Can be used as a teaching tool in classrooms.

KenKen puzzles are a blend of math and logic that provide a stimulating challenge for people of all ages.
