The puzzle is most frequently a 9 x 9 grid made up of 3 x 3 subgrids (called \"regions\"). Some cells already contain numbers, known as \"givens.\" The goal is to fill in the empty cells, one number in each, so that each column, row, and region contains the numbers 1 through 9 exactly once. Each number in the solution therefore occurs only once in each of three \"directions,\" hence the \"single numbers\" implied by the puzzle's name.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e \u003ca href=\"https:\/\/sureshotbooks-com.myshopify.com\/search?type=product%2Carticle%2Cpage\u0026amp;q=AUTH-11740248\"\u003eMindful Puzzle Books\u003c\/a\u003e\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Createspace Independent Publishing Platform\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 04\/13\/2018\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 232\u003cbr\u003e\u003cb\u003eBinding Type:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.70lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.49d\u003cbr\u003e\u003cb\u003eISBN13:\u003c\/b\u003e 9781987782936\u003cbr\u003e\u003cb\u003eISBN10:\u003c\/b\u003e 1987782933\u003cbr\u003e\u003cb\u003eBISAC Categories:\u003c\/b\u003e\u003cbr\u003e- \u003ca href=\"https:\/\/sureshotbooks-com.myshopify.com\/search?type=product%2Carticle%2Cpage\u0026amp;q=CAT-GAM\"\u003eGames \u0026amp; Activities\u003c\/a\u003e | \u003ca href=\"https:\/\/sureshotbooks-com.myshopify.com\/search?type=product%2Carticle%2Cpage\u0026amp;q=BISAC-GAM017000\"\u003eSudoku\u003c\/a\u003e\u003cbr\u003e\u003cp\u003e\u003ci\u003eThis title is not returnable\u003c\/i\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Createspace Independent Publishing Platform","offers":[{"title":"Default Title","offer_id":42651601436909,"sku":"9781987782936","price":13.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0550\/8097\/6621\/products\/img_590e2e92-3594-4a15-8cef-53cebba20b5e.jpg?v=1649222886","url":"https:\/\/sureshotbooks.com\/products\/sudoku-puzzle-book-5-400-extreme-very-hard-sudoku-9781987782936","provider":"SureShot Books Publishing LLC","version":"1.0","type":"link"}
