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.\u003c\/p\u003e\u003cp\u003e kakuro puzzle book - kakuro puzzle books for adults - kakuro books - kakuro white belt - kakuro black belt - kakuro absolutely - kakuro and sudoku - kakuro brown belt - kakuro belt - kakuro large print - kakuro medium - kakuro puzzle book brown belt - kakuro puzzle book easy - kakuro university - mathematical puzzle books - mathematical games and puzzle - mathematical crossword puzzle with answers - mathematical jigsaw puzzle - japanese mathematical puzzle - mathematical logic puzzle - mathematical matrix puzzle - mathematical mind puzzle - mathematical matching puzzle - math puzzles for middle school - math puzzle brain teasers\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Jeff Heldt\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1719898812\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781719898812\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Independently Published\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 08\/26\/2018\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 116\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.40lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.28d\u003cbr\u003e\u003cb\u003eLarge Print\u003c\/b\u003e","brand":"Jeff Heldt","offers":[{"title":"Paperback","offer_id":44716461228287,"sku":"9781719898812","price":10.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_91c900ea-e261-4bff-bbb8-7a65313e0ef1.jpg?v=1705682440","url":"https:\/\/www.whiterainbookhouse.com\/products\/kakuro-puzzle-jeff-heldt-9781719898812","provider":"WR Book House","version":"1.0","type":"link"}
