Your goal is the same as in regular sudoku: fill every row, column and 3x3 region with the numbers 1-9 once. The difference is how you arrive at those numbers. \u003cp\u003e\u003c\/p\u003e The objective is to fill the grid with numbers from 1 to 9 in a way that the following conditions are met: \u003cp\u003e\u003c\/p\u003e Each row, column, and nonet contains each number exactly once.\u003cbr\u003e The sum of all numbers in a cage must match the small number printed in its corner.\u003cbr\u003e No number appears more than once in a cage. (This is the standard rule for killer sudokus, and implies that no cage can include more than 9 cells.)\u003cbr\u003e\u003cbr\u003e","brand":"Createspace Independent Publishing Platform","offers":[{"title":"Default Title","offer_id":50362704953618,"sku":"9781725956582","price":6.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0831\/4771\/8930\/files\/img_f4e2d582-03ea-4bd3-bf80-afac5969068e.jpg?v=1728392629","url":"https:\/\/surprise-castle.myshopify.com\/products\/killer-sudoku-puzzles-200-hard-to-expert-9x9-vol-17","provider":"Surprise Castle","version":"1.0","type":"link"}
