{"product_id":"9781454917663","title":"Number-Crunching Sudoku","description":"These 99 number-crunching puzzles are sudoku PLUS! Just like the familiar sudoku that solvers love, the grids go from 1 to 9, and each number appears only once in each row, column, and box. The twist is, you need to do a little arithmetic, too—multiplying, dividing, adding, and subtracting according to the signs in the grid. It’s a fresh, challenging, and mathy take on the super-popular puzzles.\u003cbr\u003e","brand":"Puzzlewright","offers":[{"title":"Default Title","offer_id":47049180315888,"sku":"9781454917663","price":9.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781454917663_p0.jpg?v=1763848603","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781454917663","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
