Why CalcuDoku (kenken) ?
To take a break from smartphones and endless scrolling. Kids can easily get into the game if an adult introduces them to it. It helps them review (or even learn) their multiplication tables, which are increasingly less mastered. Mental calculation improves dramatically after just a few grids.

How to Play CalcuDoku / KenKen
The rules combine Sudoku mechanics with basic arithmetic:
- Fill the grid with numbers from 1 to N (where N is the grid size, e.g., 1 to 6 for a 6×6 grid).
- Do not repeat any number in the same row or column.
- Follow the outlined blocks (called “cages”): the digits inside each cage must produce the target number using the specified math operation (+, -, ×, ÷).
