{"product_id":"trifolia™","title":"TRIFOLIA™ by Kadon","description":"\u003cp class=\"p1\"\u003eThe 24 wavy tiles are a complete set of all the combinations of four types of edge: straight, hills, valleys, waves. We intended it as a gentle tribute to M.C. Escher's genius in geometric transformations. Then we found that, mathematically, they are also cousins of Multimatch III triangles. The checkerboarding of solutions isn't required, but it's nice to know that most of the figures in the book can be solved that way. (Thank you, Anneke Treep, for working those out on our office rug.) And thanks to Toby Gottfried for proving by computer that this puzzle has 2.3 million solutions! Jacques Haubrich found that only 297 of those are checkerboarded. Toby then found that only 7 of those have the three same-sided tiles at the corners of the large interior triangle (see solution at left). He also found that there are 173 solutions with both colors grouped. All-acrylic, in bold and mellow colors, with 8 \" tray. For 1 to 4 players, ages 12 to adult.\u003c\/p\u003e","brand":"UniPuzzle Store","offers":[{"title":"Default Title","offer_id":44710619676714,"sku":null,"price":65.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0723\/1209\/4762\/files\/trifolia.png?v=1787274357","url":"https:\/\/store.unipuzzle.com\/products\/trifolia%e2%84%a2","provider":"UniPuzzle Store","version":"1.0","type":"link"}
