With our special KenKen 6x6 puzzles you can learn the division and multiplication tables.

We have made a small adjustment to the classic kenken rules to focus more on specific mathematics topics

On this page we use kenken puzzles, also known as calcudoku, to practice the division tables.

There are dividends in the first cell of each cage. Use your knowledge of the division tables to find quotient and divisor of each dividend and place them in the right cell.

In our kenken puzzles cages consist of 2 cells. These cells can be connected other horizontal, vertical or diagonal.

There are 4 levels to practice the division tables:

  • Level 1: division tables 1 to 6.
  • Level 2: division tables 2 to 7.
  • Level 3: division tables 3 to 8.
  • Level 4: division tables 4 to 9.

We have also developed a bigger version, namely a kenken 8x8. Our latest version is kenken with fractions.


TIP: use the arrow keys to move the cursor in the grid.
