{"product_id":"9781708313135","title":"Sudoku 12X12 - 200 Very Hard Puzzles","description":"The puzzle a 12 x 12 grid made up of 3 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 12 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\u003cbr\u003e\u003cul\u003e\n\u003cli\u003e| \u003cb\u003eAuthor: \u003c\/b\u003eLiam Parker\u003c\/li\u003e\n\u003cli\u003e| \u003cb\u003ePublisher: \u003c\/b\u003eIndependently Published\u003c\/li\u003e\n\u003cli\u003e| \u003cb\u003ePublication Date: \u003c\/b\u003eNov 14, 2019\u003c\/li\u003e\n\u003cli\u003e| \u003cb\u003eNumber of Pages: \u003c\/b\u003e118 pages\u003c\/li\u003e\n\u003cli\u003e| \u003cb\u003eLanguage: \u003c\/b\u003eEnglish\u003c\/li\u003e\n\u003cli\u003e| \u003cb\u003eBinding: \u003c\/b\u003ePaperback\u003c\/li\u003e\n\u003cli\u003e| \u003cb\u003eISBN-10: \u003c\/b\u003e1708313133\u003c\/li\u003e\n\u003cli\u003e| \u003cb\u003eISBN-13: \u003c\/b\u003e9781708313135\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Independently published","offers":[{"title":"Default Title","offer_id":49163440914737,"sku":"9781708313135","price":13.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0798\/8215\/8385\/files\/9781708313135__80500_25e3ae2c-3586-43d8-a232-7e2c23463751.jpg?v=1716375078","url":"https:\/\/www.recomparo.com\/products\/9781708313135","provider":"ReComparo.com","version":"1.0","type":"link"}
