Your task is to fit all \u003cstrong data-start=\"277\" data-end=\"306\"\u003e13 uniquely shaped pieces\u003c\/strong\u003e inside the box. But you'll quickly discover that packing everything inside is only half the challenge.\u003c\/p\u003e\n\u003cp data-start=\"411\" data-end=\"755\"\u003eEach puzzle piece has a bore running through it. When assembled correctly, these bores align to form a continuous tunnel from the unrestricted opening at the top of the box to the circular cutout in the bottom. Drop the included \u003cstrong data-start=\"640\" data-end=\"660\"\u003e16 mm steel ball\u003c\/strong\u003e into the box, and it should pass through every single piece before exiting through the bottom.\u003c\/p\u003e\n\u003cp data-start=\"757\" data-end=\"813\"\u003eThere is \u003cstrong data-start=\"766\" data-end=\"778\"\u003eonly one\u003c\/strong\u003e assembly that makes this possible.\u003c\/p\u003e\n\u003cp data-start=\"815\" data-end=\"1077\"\u003eInterestingly, there are \u003cstrong data-start=\"840\" data-end=\"863\"\u003etwo additional ways\u003c\/strong\u003e to pack all 13 pieces perfectly flush inside the box. While they appear to be valid solutions, the tunnel is blocked, trapping the steel ball inside. Only the true solution allows the ball to complete its journey.\u003c\/p\u003e\n\u003cp data-start=\"1079\" data-end=\"1226\"\u003eA brilliant combination of a packing puzzle and a hidden ball maze, TCR challenges your spatial reasoning while rewarding patience and persistence.\u003c\/p\u003e\n\u003cp data-start=\"1228\" data-end=\"1376\"\u003e\u003cstrong data-start=\"1228\" data-end=\"1237\"\u003eGoal:\u003c\/strong\u003e Pack all 13 pieces inside the box so the 16 mm steel ball passes through every piece and exits through the circular opening in the bottom.\u003c\/p\u003e\n\u003cp data-start=\"1378\" data-end=\"1489\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e\u003cstrong data-start=\"1378\" data-end=\"1391\"\u003eDesigner:\u003c\/strong\u003e Dr. Volker Latussek\u003cbr data-start=\"1411\" data-end=\"1414\"\u003e\u003cstrong data-start=\"1414\" data-end=\"1435\"\u003eNumber of pieces:\u003c\/strong\u003e 13 + 16 mm steel ball\u003cbr data-start=\"1457\" data-end=\"1460\"\u003e\u003cstrong data-start=\"1460\" data-end=\"1473\"\u003eBox size:\u003c\/strong\u003e 68 × 68 × 64 mm\u003c\/p\u003e","brand":"Puzzle Guy Store","offers":[{"title":"Default Title","offer_id":54570521264470,"sku":null,"price":47.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0941\/0127\/4966\/files\/TCR-1.png?v=1784222387","url":"https:\/\/puzzleguy.store\/products\/tcr-the-ultimate-packing-challenge","provider":"Puzzle Guy Store","version":"1.0","type":"link"}
