Mental Floss Logic Puzzles: Kakuro 9×9 Puzzles (Brainteaser Puzzles for Adults)

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: logic games – logic game puzzle – logic puzzles – logic puzzle books for adults – logic puzzle books for teens – logic puzzle for adults – logic puzzles riddles – brainteasers for adults – brainteaser puzzles for adults – brainteaser books for adults – brainteaser adults – brainteaser for adults – brainteaser games for adults – brainteaser jigsaw puzzles – logic puzzle large print
