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 8518845092\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9798518845091\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Independently Published\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 06\/11\/2021\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":43945013412095,"sku":"9798518845091","price":7.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/products\/img_fe1e85db-2c16-4ddd-b8d9-884931e2f7a5.jpg?v=1681506276","url":"https:\/\/www.whiterainbookhouse.com\/products\/calcudoku-puzzles-mixed-200-liam-parker-9798518845091","provider":"WR Book House","version":"1.0","type":"link"}
