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\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Fumiko Kawai\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1983063258\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781983063251\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Independently Published\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 06\/02\/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","brand":"Fumiko Kawai","offers":[{"title":"Paperback","offer_id":43940593533183,"sku":"9781983063251","price":10.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/products\/img_aed5b7bc-f1c5-4cff-8891-7573bf4f7e89.jpg?v=1681448080","url":"https:\/\/www.whiterainbookhouse.com\/products\/kakuro-hard-fumiko-kawai-9781983063251","provider":"WR Book House","version":"1.0","type":"link"}
