400 Hard Calcudoku Puzzles
Calcudoku is similar to Sudoku in the fact that the numbers 1-9 must be entered into every row and column, with only one instance of each number allowed.
Grids are split into smaller sections of two or more squares by thick, black border lines. Within one of these squares is a number and a mathematical symbol (addition, subtraction, multiplication and division are all used). The number in the box is the answer to the sum, which must be obtained by using the mathematical symbol.
Six – 9×9 puzzles per page set out in a large 8.5 x 11 inch format.
With 400 hard Calcudoku puzzles, the Calcudoku book is sure to keep you entertained for countless hours.
All puzzle solutions are at the back of the book.
