This book contains 150 kakuros. It takes cue from the belt colors in martial arts: white is for novices, green for intermediates, brown for very accomplished players, and black for those consummate experts who crave a challenge.","brand":"Conceptis Puzzles","offers":[{"title":"Paperback","offer_id":46352218783980,"sku":"9781402739354","price":11.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0684\/1791\/3068\/files\/9781402739354.jpg?v=1744230342","url":"https:\/\/intl.allstora.com\/products\/brown-belt-kakuro","provider":"Allstora","version":"1.0","type":"link"}
