{"product_id":"mega-sudoku-200-hard-david-smith-9781090508119","title":"Mega Sudoku - 200 Hard to Master Puzzles 16x16 Vol.7","description":"The puzzle a 16 x 16 grid made up of 4 x 4 subgrids (called \"regions\"). 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 16 exactly once. Each number in the solution therefore occurs only once in each of three \"directions,\" hence the \"single numbers\" implied by the puzzle's name.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e David Smith\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1090508115\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781090508119\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Independently Published\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 03\/14\/2019\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 118\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.37lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.25d","brand":"David Smith","offers":[{"title":"Paperback","offer_id":43980834177279,"sku":"9781090508119","price":7.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_1a469df2-735f-43b4-b3c5-fdfd8d852696.jpg?v=1683252152","url":"https:\/\/www.whiterainbookhouse.com\/products\/mega-sudoku-200-hard-david-smith-9781090508119","provider":"WR Book House","version":"1.0","type":"link"}
