The puzzle is played on a square grid, such as 8 x 8. The objective is to place the numbers 1 to 8 (or whatever the dimensions are) in each row, ensuring that each column also only contains the digits 1 to 8. Some digits may be given at the start. In addition, inequality constraints are also initially specifed between some of the squares, such that one must be higher or lower than its neighbour. These constraints must be honoured as the grid is filled out.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Mindful Puzzle Books\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1728717191\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781728717197\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":44169906192639,"sku":"9781728717197","price":8.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_9da6c81b-6e8d-467c-9632-98abf96415de.jpg?v=1689655610","url":"https:\/\/www.whiterainbookhouse.com\/products\/futoshiki-mindful-puzzle-books-9781728717197","provider":"WR Book House","version":"1.0","type":"link"}
