Kakuro Puzzle Book: Cross Sums Math Logic Brain Teasers For Adult Of All Ages (Paperback) (ISBN-13: 9798591140816)

• Kakuro (also known as Cross Sums) is a mathematic logic puzzle. The puzzle consists of a playing area of filled and empty cells similar to crossword puzzles.
• The rules of Kakuro are simple - place the numbers 1 to 9 into the puzzle grid so that each continuous horizontal or vertical run of empty squares adds up to the value to the left of it or above it respectively. This value is shown either to the right or below a diagonal line. However, no digit can be duplicated in an entry. For example for the total 6, you could have 1 and 5 or 2 and 4 but not 3 and 3.
• If you like and enjoy Math Logic Puzzles, then you will love Kakuro Puzzles.
