{"product_id":"250-sudoku-puzzles-mindful-puzzle-books-9781727193077","title":"250 Sudoku Puzzles: Hard Sudoku Puzzles","description":"Sudoku (also known as \"Number Place\") is a placement puzzle. The puzzle is most frequently a 9 x 9 grid made up of 3 x 3 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 9 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 Mindful Puzzle Books\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1727193075\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781727193077\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 09\/10\/2018\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 146\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.45lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.31d","brand":"Mindful Puzzle Books","offers":[{"title":"Paperback","offer_id":44756774256895,"sku":"9781727193077","price":9.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_371a1347-14ba-4422-aae6-6b1e5545d3f6.jpg?v=1706593814","url":"https:\/\/www.whiterainbookhouse.com\/products\/250-sudoku-puzzles-mindful-puzzle-books-9781727193077","provider":"WR Book House","version":"1.0","type":"link"}
