More Description Calcudoku (also known as "Mathdoku") is a mathematical and logical puzzle loosely similar to Sudoku.
The objective is to fill the grid in with the digits 1 through N (where N is the number of rows or columns in the grid) such that:
* Each row contains exactly one of each digit.

* Unlike Killer Sudoku, digits may repeat within a block.
