Book excerpt: Kakuro (also known as "Cross Sums") is a logical puzzle, a mathematical equivalent of crosswords. The puzzle consists of a playing area of filled and empty cells similar to a crossword puzzle. Some black cells contain a diagonal slash from top left to bottom right with numbers in them, called "the clues." A number in the top right corner relates to an "across" clue and one in the bottom left a "down" clue. The object of a kakuro is to insert digits from 1 to 9 into the white cells to total the clue associated with it. However no digit can be duplicated in an entry. For example the total 6 you could have 1 and 5, 2 and 4 but not 3 and 3. ============ KEYWORDS / TAGS: kakuro puzzle books - kakuro puzzle books for adults - kakuro and sudoku - kakuro cross sums - kakuro large print - math puzzles - math puzzles for adults - math puzzle books - math puzzle books for adults - math jigsaw puzzles - math puzzle logic - logic puzzles - logic puzzles for adults - logic puzzle books for teens - logic puzzle adult - logic puzzles daily
