Some cells already contain numbers, known as \"givens\". 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\".\n            \u003cdiv\u003e\n\u003cstrong\u003eNumber of Pages:\u003c\/strong\u003e 54\u003c\/div\u003e\n            \u003cdiv\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 0.11 x 9.02 x 5.98 IN\u003c\/div\u003e\n            \u003cdiv\u003e\n\u003cstrong\u003ePublication Date:\u003c\/strong\u003e January 16, 2020\u003c\/div\u003e\n            ","brand":"BooksCloud","offers":[{"title":"Default Title","offer_id":52592944513331,"sku":"9781661604448","price":16.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0300\/5595\/6612\/files\/rS6-ATX489781661604448.webp?v=1761688459","url":"https:\/\/www.vysn.com\/en-ca\/products\/sudoku-x-200-hard-puzzles-9x9-volume-7-paperback","provider":"VYSN","version":"1.0","type":"link"}
