{"product_id":"the-big-book-of-logic-mykola-krylov-9781545385500","title":"The Big Book of Logic Puzzles - Hashi 400 Logic (Volume 44)","description":"Hashi (also known as \"Hashiwokakero\" from Japanese \"Hashi o kakero\"; literally \"build bridges\"; \"Bridges\", \"Chopsticks\", or \"Ai-Ki-Ai\") is a type of logic puzzle. It is played on a rectangular grid with no standard size, although the grid itself is not usually drawn. Some cells start out with (usually encircled) numbers from 1 to 8 inclusive; these are the islands. The rest of the cells are empty.The goal is to connect all of the islands into a single connected group by drawing a series of bridges between the islands. The bridges must follow certain criteria: -They must begin and end at distinct islands, travelling a straight line in between.-They must not cross any other bridges or islands.-They may only run orthogonally.-At most two bridges connect a pair of islands.-The number of bridges connected to each island must match the number on that island.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Mykola Krylov\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1545385505\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781545385500\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Createspace Independent Publishing Platform\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 04\/16\/2017\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 272\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.81lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.57d","brand":"Mykola Krylov","offers":[{"title":"Paperback","offer_id":44067452879103,"sku":"9781545385500","price":12.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_d1fcfcb2-fe85-40d5-a45d-2e98596dbe57.jpg?v=1685413317","url":"https:\/\/www.whiterainbookhouse.com\/products\/the-big-book-of-logic-mykola-krylov-9781545385500","provider":"WR Book House","version":"1.0","type":"link"}
