It is also spelled hutosiki (using Kunrei-shiki romanization).The puzzle is played on a square grid, such as 9 x 9. The objective is to place the numbers 1 to 9 (or whatever the dimensions are) such that each row, and column contains each of the digits 1 to 9. Some digits may be given at the start. In addition, inequality constraints are also initially specified 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 Mykola Krylov\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1544149212\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781544149219\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 02\/26\/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":44067423518975,"sku":"9781544149219","price":12.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_41072009-2bf0-49d8-970f-edb79e420c07.jpg?v=1685413143","url":"https:\/\/www.whiterainbookhouse.com\/products\/the-big-book-of-logic-mykola-krylov-9781544149219","provider":"WR Book House","version":"1.0","type":"link"}
