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.
• Each column contains exactly one of each digit.
• Each bold-outlined group of cells (block) contains digits which achieve the specified result using the specified mathematical operation: addition (+), subtraction (-), multiplication (�), and division (�).
• Unlike Killer Sudoku, digits may repeat within a block.

The puzzle book contain:
• 200 Puzzles
• Handy 6 x 9 inch Book Layout
• 2 Puzzles per Page
• Ideal for Experts

In the book you will find a description and examples of solutions for all puzzles.
The book is for those who like logic and math problems. Decide, developing and improving.
