The goal is to fill in the empty cells, one number in each, so that each column, row, and region contains the numbers 1 through 9 exactly once. Main diagonals also contain the digits 1 through 9. Each number in the solution therefore occurs only once in each of three \"directions\".\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Michael Brown\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1983593346\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781983593345\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Createspace Independent Publishing Platform\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 02\/14\/2018\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 54\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.19lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.02h x 5.98w x 0.11d","brand":"Michael Brown","offers":[{"title":"Paperback","offer_id":44761333367039,"sku":"9781983593345","price":6.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_aba455e1-9ebd-442a-89c9-75e759c39fe6.jpg?v=1706681031","url":"https:\/\/www.whiterainbookhouse.com\/products\/sudoku-x-200-master-michael-brown-9781983593345","provider":"WR Book House","version":"1.0","type":"link"}
