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).\u003c\/p\u003e","brand":"Independently Published","offers":[{"title":"Paperback","offer_id":45541707284631,"sku":"9781728735672","price":901.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9781728735672.webp?v=1767120504","url":"https:\/\/atlanticbooks.com\/products\/hitori-250-challenging-logic-puzzles-7x7-9781728735672","provider":"Atlantic Books","version":"1.0","type":"link"}
