{"product_id":"hitori-mindful-puzzle-books-9781728731759","title":"Hitori: 250 Challenging Logic Puzzles 4x4","description":"Hitori 250 Challenging Logic Puzzles 4x4.Hitori (from Japanese \"Hitori ni shite kure\"; literally \"let me alone\") is played on a grid of squares. At the beginning, each cell contains a number. The goal is to paint out some cells so that there are no duplicate numbers in any row or column, similar to the solved state of a Sudoku puzzle (except with black squares added to the grid).Orthogonal connections are important as well; painted-out (black) cells cannot be connected orthogonally, and the other cells must be connected orthogonally in a single group (i.e. no two black squares can be adjacent to each other, and all un-painted squares must be connected, horizontally or vertically, to create a single shape).\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Mindful Puzzle Books\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1728731755\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781728731759\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Independently Published\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 10\/12\/2018\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 146\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.45lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.31d","brand":"Mindful Puzzle Books","offers":[{"title":"Paperback","offer_id":47419559051519,"sku":"9781728731759","price":9.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_54d6e86f-7a1f-42a3-88bf-b21d6a86d56a.jpg?v=1761512342","url":"https:\/\/www.whiterainbookhouse.com\/products\/hitori-mindful-puzzle-books-9781728731759","provider":"WR Book House","version":"1.0","type":"link"}
