{"product_id":"balance-quest-whit-mcmahan-9781477264096","title":"Balance Quest: A Numeric Progression Puzzle","description":"Balance Quest is a numeric progression puzzle consisting of a set of rectangles arranged within a hierarchical grid. Some of the rectangles contain positive or negative integers, while others are blank. The objective is to fill in each blank rectangle with an integer in a way that \"balances\" the puzzle mathematically. The puzzle features three skill levels (Easy, par, and challenging) with three grid sizes: BQ Sixteen (small-grid), BQ Thirty-two (medium-grid), and BQ Sixty-four (large-grid). Solve time can range from 5 minutes for the \"easy\" small puzzles to hours for the \"challenging\" large puzzles. This puzzle is for ages 10+.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Whit McMahan\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1477264094\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781477264096\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Authorhouse\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 08\/30\/2012\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 94\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.51lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 11.00h x 8.25w x 0.19d","brand":"Whit McMahan","offers":[{"title":"Paperback","offer_id":44138595188991,"sku":"9781477264096","price":14.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_f2b011c8-3c36-46ef-bf6b-4867f82c18e0.jpg?v=1687900512","url":"https:\/\/www.whiterainbookhouse.com\/products\/balance-quest-whit-mcmahan-9781477264096","provider":"WR Book House","version":"1.0","type":"link"}
