The object is to fill all empty squares so that the numbers 1 to N (where N is the number of rows or columns in the grid) appear exactly once in each row and column and the numbers in each block produce the result shown in the top-left corner of the block according to the math operation appearing on the top of the grid. In CalcuDoku a number may be used more than once in the same block.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Liam Parker\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1688494405\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781688494404\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Independently Published\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 08\/25\/2019\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 118\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.37lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.02h x 5.98w x 0.25d","brand":"Liam Parker","offers":[{"title":"Paperback","offer_id":46431412879615,"sku":"9781688494404","price":6.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_654fbf82-91b6-4a6b-8432-e3ca25773fc6.jpg?v=1735141247","url":"https:\/\/www.whiterainbookhouse.com\/products\/calcudoku-puzzles-200-normal-liam-parker-9781688494404","provider":"WR Book House","version":"1.0","type":"link"}
