{"product_id":"9780764350542","title":"Sweet 16: A New Numbers Puzzle","description":"Sharpen your pencil and get ready to boost your brain with this brand-new numbers game. To solve each puzzle, fill the 16 cells with the numbers 1 to 16 using each number only once. Each puzzle has just one solution, and uses math you learned in grade school: addition, subtraction, multiplication, and division. The games, which all call for logic, imaginative thinking, intuitive elimination, and sheer persistence, are grouped in three categories, and range from relatively simple to super-challenging. The author's spirited instructions and sample puzzles walk you through the basics; clues for some puzzles provide what might be necessary encouragement. With 14 bonus puzzles aimed at children and those who want to start with the ultra-easy, these 150 puzzles will keep you thinking whether you're a student honing your math skills, a puzzle-lover looking for a challenge, or someone who just wants to get those brain synapses snapping!","brand":"Schiffer Publishing, Ltd.","offers":[{"title":"Default Title","offer_id":47025749033200,"sku":"9780764350542","price":9.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9780764350542_p0.jpg?v=1763801115","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780764350542","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
