{"product_id":"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.\u003cbr\u003eThe 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:\u003cbr\u003e• They must begin and end at distinct islands, travelling a straight line in between.\u003cbr\u003e• They must not cross any other bridges or islands.\u003cbr\u003e• They may only run orthogonally.\u003cbr\u003e• At most two bridges connect a pair of islands.\u003cbr\u003e• The number of bridges connected to each island must match the number on that island.","brand":"CreateSpace Publishing","offers":[{"title":"Default Title","offer_id":48210886328560,"sku":"9781545385500","price":10.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781545385500_p0.jpg?v=1763751493","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781545385500","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
