A fiendishly difficult double sided puzzle with only 529 pieces. This fantastic puzzle will have you hooked for hours as you try to figure out where each piece connects. Each side has exactly the same ‘Sweet Shop’ artwork and it’s impossible to tell which side is which – it will really have you scratching your head! Each side has the identical image offset 90 degrees from each other which is cut from both sides so it’s impossible to tell which side is which! Though it has only 529 pieces, it will feel more like 4000! Each piece must be compared on both sides for size, shape, colour and fit. If all this sounds confusing just wait until you try it. This puzzle is made from high quality card and comes presented in a rectangular box which has been shrink wrapped for further protection. Finished puzzle measures 384mm x 384mm.
