{"product_id":"hexadoku-sudoku-with-a-hexadecimal-twist-9781453644713","title":"Hexadoku: Sudoku with a hexadecimal twist","description":"Hexadoku is a challenging variant of sudoku that uses the set of sixteen hexadecimal digits, instead of the traditional nine. It is played on a 16x16 grid, which means there are over three times the number of cells that need to be filled in! No knowledge of hexadecimal is needed to play... just a bit of logic and a sharp pencil. (This book contains three hundred hexadoku puzzles grouped into four difficulty levels.)\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Keith Elder\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Createspace Independent Publishing Platform\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 07\/01\/2010\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 206\u003cbr\u003e\u003cb\u003eBinding Type:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.62lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.02h x 5.98w x 0.44d\u003cbr\u003e\u003cb\u003eISBN:\u003c\/b\u003e 9781453644713\u003cp\u003e\u003ci\u003eThis title is not returnable\u003c\/i\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Createspace Independent Publishing Platform","offers":[{"title":"Paperback","offer_id":44999368769651,"sku":"9781453644713","price":14.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/9255\/0515\/files\/img_9b4a3903-1482-44ae-bb2a-0515802bbb76.jpg?v=1779048613","url":"https:\/\/bookstorenmore.com\/products\/hexadoku-sudoku-with-a-hexadecimal-twist-9781453644713","provider":"Bookstore N More","version":"1.0","type":"link"}
