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","brand":"Createspace Independent Publishing Platform","offers":[{"title":"Default Title","offer_id":50855109787922,"sku":"9781545384749","price":11.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0831\/4771\/8930\/files\/img_9bb189ac-2717-4da6-b092-74b1c75badef.jpg?v=1737477923","url":"https:\/\/surprise-castle.myshopify.com\/products\/the-big-book-of-logic-puzzles-hitori-400-logic-volume-43-9781545384749","provider":"Surprise Castle","version":"1.0","type":"link"}
