Requiring just pure logic and simple add\/subtract calculations, these numerical-crossword puzzles (100) will carry you into a fascinating world of number combinations you never imagined could exist.The task in Kakuro puzzles is to fill all empty squares using numbers 1 to 9 so the sum of each horizontal block equals the clue on its left, and the sum of each vertical block equals the clue on its top. In addition, no number may be used in the same block more than once. There is only one unique solution for each puzzle.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Hat House\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1656022427\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781656022424\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Independently Published\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 01\/05\/2020\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 80\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.46lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 11.02h x 8.50w x 0.17d","brand":"Hat House","offers":[{"title":"Paperback","offer_id":43941848088831,"sku":"9781656022424","price":5.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/products\/img_e4506ea3-7069-4b79-82c1-a8e80908b6a2.jpg?v=1681455313","url":"https:\/\/www.whiterainbookhouse.com\/products\/kakuro-challenge-hat-house-9781656022424","provider":"WR Book House","version":"1.0","type":"link"}
