Kakuro Cross Sums Hard Volume 1

Very easy to read Plenty of room to write possible solutions 200 puzzles and solutions 2 puzzles per page Downloadable reference guide Ideal for Experienced Kakuro puzzle solvers Kakuro puzzles are number puzzles solved in a crossword style grid. 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 reference guide listing the target numbers with only one possible combination. The full number combinations can be downloaded as a PDF file. All puzzles have unique solutions and can be solved using logical methods without guessing.
