Daily Calcudoku
Frequently Asked Questions
What is Calcudoku?
Calcudoku (also known as KenKen or Mathdoku) is a logic puzzle where you fill a grid with numbers so that no number repeats in any row or column, and the numbers within "cages" must produce a specific total using the indicated math operation.
Is Calcudoku harder than Sudoku?
It offers an extra challenge because it requires both logic and basic arithmetic (addition, subtraction, multiplication, and division).
How often are new puzzles released?
Just like our other logic games, a fresh Calcudoku puzzle is available every day at midnight.
