A rectangular or square grid is divided into regions. The goal is to blacken some cells of a grid (\"stones\") according to the following rules: - All black cells in a region must be connected horizontally or vertically. - A cell with a number indicates how many cells in the region must be blackened. - In regions without a number any amount of cells may be blackened (at least one). - When two cells are orthogonally adjacent across a region boundary, at least one cell must be white. - If all stones \"fall down\", they must cover exactly the bottom half of the grid.\u003c\/p\u003e\u003cp\u003ebrain teasers for kids ages 10-12 - brain teasers for kids - brain teaser games - brain teaser puzzles for kids - brain teaser books for kids - brain teaser for kids - brain teaser for teens - brain teaser for kids ages 8-10 - brain teaser games for kids - brain teaser games for kids ages 10-12 - brain teaser gifts - brain teaser travel games for kids\u003c\/p\u003e","brand":"Independently Published","offers":[{"title":"Paperback","offer_id":45534051369111,"sku":"9781717783349","price":931.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9781717783349.webp?v=1767112256","url":"https:\/\/atlanticbooks.com\/products\/logic-games-for-boys-stostone-logic-puzzles-with-answers-9781717783349","provider":"Atlantic Books","version":"1.0","type":"link"}
