A number above the diagonal line in a black square represents the total of the numbers in the white squares to the right of it; similarly, a number below the diagonal line is the total sum of the digits in the white squares below it. The white squares can contain any of the digits 1 to 9, however, these digits cannot be repeated more than once in any vertical column or horizontal line to make the target number. For example, if the total number in the black square is 4 and there are 2 white squares, the digits must be 1 and 3, they cannot be 2 and 2. Located at the back of this book is a handy reference guide listing all the possible combinations for the numbers from 3 to 45, also listed are the target numbers with only one possible combination. All puzzles have unique solutions and can be solved using logical methods without guessing. - Very easy to read - Wide Inner Margin - 95 Normal Kakuro Cross Sum puzzles and solutions - Only 1 puzzles per page - Full number combinations reference guide - Ideal for Beginner Solvers
