Rules For Playing KenKen®
The numbers you use in a KenKen puzzle depend on the size of the grid you choose. A 3 x 3 grid (3 squares across, 3 squares down) means you use the numbers 1, 2, and 3. A 4 x 4 grid, uses numbers 1 to 4. A 5x5 grid requires you use the numbers 1 to 5, and so on all the way up to 9x9.
The numbers in each heavily outlined set of squares, called cages, must add, subtract, multiply, or divide (in any order) to produce the target number in the top corner using only the mathematic operation indicated (+, -, ×, ÷).
Here's how you play:
- Use each number only once per row, once per column.
- Cages with just one square should be filled in with the target number in the top corner.
- A number can be repeated within a cage as long as it is not in the same row or column.
