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 David Smith\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Independently Published\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 04\/24\/2019\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 118\u003cbr\u003e\u003cb\u003eBinding Type:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.37lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.25d\u003cbr\u003e\u003cb\u003eISBN:\u003c\/b\u003e 9781095765036\u003cp\u003e\u003ci\u003eThis title is not returnable\u003c\/i\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Independently Published","offers":[{"title":"Paperback","offer_id":43945546481779,"sku":"9.7811E+12","price":9.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/9255\/0515\/files\/img_94e1cad0-6dca-4e19-b9bd-5223081fa179.jpg?v=1759233535","url":"https:\/\/bookstorenmore.com\/products\/calcudoku-puzzles-200-master-puzzles-9x9-vol20-9781095765036","provider":"Bookstore N More","version":"1.0","type":"link"}
