Rules and Examples

Like sudoku, kakuro will call on your powers of logic to find a
solution. But kakuro has an element of math - elementary addition and
subtraction is also required. Numbers on the black squares are the target for a
sum of numbers between 1 and 9 that you will place in the white squares.

The clue represents the sum of the numbers in the adjacent block of empty cells

The numbers 1 to 9 are used to fill the grid

Each block may contain only one occurrence of a digit

A 'normal' Kakuro board is around 9 x 9 cells, but the height and width can vary. For books a good
size if 9 by 15. We can produce kakuro in these dimensions all the way up to 25 x 25.
