{"product_id":"modus-fortis-sudoku-logic-sudoku-sudoku-sam-9781684982233","title":"MODUS FORTIS Sudoku Logic, Sudoku Reason","description":"\u003cp\u003eModus Fortis represents a Khunian shift in Sudoku strategy. Using just four basic tactics that give rise to just two molecular structures--Doubles and Pairs--that evolve into just two Families of complex structures (Exclusive Sets and Forbidden Sets) is all that is needed to solve every Sudoku. But just as E = mc2 is easy to visualize, there is a bit more to understanding the equation. The logical principle that drives the Solution Process is the Exclusive Disjunction: the Modus Fortis. This, combined with the Pairing Principle, guides the Sudoku-ka through the process of constructing a Solution from emerging Sets of Digits, identifiable as structural patterns. A concise notation system allows for recording every significant event in the Solution Process, just as in chess. Richly illustrated, this is a readable book for all levels of interest.\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Sudoku Sam\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1684982235\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781684982233\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Newman Springs\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 06\/21\/2024\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 376\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 1.57lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 8.50w x 0.78d","brand":"Sudoku Sam","offers":[{"title":"Paperback","offer_id":46094364606719,"sku":"9781684982233","price":31.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_13ec953f-fc09-4eaf-a298-720d70fc6374.jpg?v=1724844440","url":"https:\/\/www.whiterainbookhouse.com\/products\/modus-fortis-sudoku-logic-sudoku-sudoku-sam-9781684982233","provider":"WR Book House","version":"1.0","type":"link"}
