Each Calcudoku puzzle consists of a grid containing blocks surrounded by bold lines. The object is to fill all empty squares so that the numbers 1 to 6 appear exactly once in each row and column and the numbers in each block produce the result of the math operation shown in the top-left corner of the block. In Calcudoku, a number may be used more than once in the same block.
