What Is a Mathdoku Puzzle?

Mathdoku is a number puzzle played on a square grid divided into cages. Fill the grid so that each number appears only once in every row and column. The numbers inside each cage must produce the target number by using the displayed operation. Mathdoku is also commonly known as Calcudoku.

How to Solve Mathdoku Puzzles

First, check the size of the grid. A 3×3 puzzle uses the numbers 1 to 3, while a 4×4 puzzle uses the numbers 1 to 4. Then follow these rules:

  1. Use each number only once in every row.
  2. Use each number only once in every column.
  3. Complete each cage by reaching its target number with the shown operation.
  4. For subtraction and division cages, check both possible number orders.
  5. Review the rows, columns, and cages before finishing the puzzle.
