The purpose of its creation was to present a puzzle that uses no numbers or letters and yet retains depth and aesthetics. \u003cp\u003e\u003c\/p\u003e Masyu is played on a rectangular grid of squares, some of which contain circles, each circle is either \"white\" (empty) or \"black\" (filled). The goal is to draw a single continuous non-intersecting loop that properly passes through all circled cells. The loop must \"enter\" each cell it passes through from the center of one of its four sides and \"exit\" from a different side, all turns are therefore 90 degrees. The two varieties of circle have differing requirements for how the loop must pass through them: \u003cbr\u003e - White circles must be traveled straight through, but the loop must turn in the previous and\/or next cell in its path.\u003cbr\u003e - Black circles must be turned upon, but the loop must travel straight through the next and previous cells in its path.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Dart Veider\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 172353241X\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781723532412\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 07\/23\/2018\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 138\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.43lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.02h x 5.98w x 0.30d","brand":"Dart Veider","offers":[{"title":"Paperback","offer_id":46420316455167,"sku":"9781723532412","price":7.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_82b11f15-746a-4589-95af-9215bdc93bf8.jpg?v=1734634272","url":"https:\/\/www.whiterainbookhouse.com\/products\/sudoku-masyu-200-hard-dart-veider-9781723532412","provider":"WR Book House","version":"1.0","type":"link"}
