Kakuro puzzles (often referred to as Cross Sums or Cross Addition 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.
All puzzles are unique with solutions located in the back of the book. The 8.5 x 11in pages also gives tons of space for working methods or writing notes. You will have hours of fun working the puzzles and sharpening your brain. These mathematical logic-solving puzzles assist in brain fitness and brain health. The 8.5 x 11in size makes it easy to toss into your purse, backpack, or daily bag. Kakuro Puzzle Book for Adults makes an ideal gift for the puzzle lover in your life.
