Each tile contains embedded magnets, and instead of simply picking up or sliding individual pieces, you must use the included magnetic tool to lift a group of two or three tiles at once.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eOnce lifted, the entire group can be rotated and placed back into the grid. These unusual moves are used both to scramble the puzzle and to solve it.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe goal sounds simple: restore all of the numbered tiles to their correct order. But the restrictions created by the grouped moves make Propp Tiles much more interesting than an ordinary tile puzzle.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThere is another mathematical twist. If the tiles are assembled randomly, there is a high probability that the resulting position cannot be solved at all. This raises an intriguing question behind the puzzle: \u003c\/span\u003ewhat is the probability that a random arrangement is actually solvable?\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003ePropp Tiles combines mechanical movement, magnets, logic and mathematics into a very unusual puzzle that feels unlike a traditional sliding puzzle.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003eInventor:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e James (Jim) Propp\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003e\u003cspan\u003eDesigner:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Oskar van Deventer\u003c\/span\u003e\u003c\/p\u003e","brand":"Puzzle Guy Store","offers":[{"title":"4x4","offer_id":55124894450006,"sku":"OVD-064-A","price":27.0,"currency_code":"USD","in_stock":true},{"title":"4x5","offer_id":55124894482774,"sku":"OVD-064-B","price":29.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0941\/0127\/4966\/files\/ProppTiles-1.jpg?v=1787945810","url":"https:\/\/puzzleguy.store\/products\/propp-tiles","provider":"Puzzle Guy Store","version":"1.0","type":"link"}
