{"product_id":"9781729812853","title":"Sudoku Windoku - 200 Hard Puzzles 9X9","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. Windoku (also known as \"Four-Box Sudoku\", \"Hyper Sudoku\") is a variant of sudoku, contain additional four regions 3 x 3.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003e• \u003cb\u003eAuthor: \u003c\/b\u003eDart Veider\u003c\/li\u003e\n\u003cli\u003e• \u003cb\u003ePublisher: \u003c\/b\u003eCreatespace Independent Publishing Platform\u003c\/li\u003e\n\u003cli\u003e• \u003cb\u003ePublication Date: \u003c\/b\u003eNov 24, 2018\u003c\/li\u003e\n\u003cli\u003e• \u003cb\u003eNumber of Pages: \u003c\/b\u003e136 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\u003e1729812856\u003c\/li\u003e\n\u003cli\u003e• \u003cb\u003eISBN-13: \u003c\/b\u003e9781729812853\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Createspace Independent Publishing Platform","offers":[{"title":"Default Title","offer_id":50368307691825,"sku":"9781729812853","price":12.01,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0798\/8215\/8385\/files\/9781729812853__02264.jpg?v=1732546348","url":"https:\/\/www.recomparo.com\/products\/9781729812853","provider":"ReComparo.com","version":"1.0","type":"link"}
