Fiendishly difficult double sided puzzle
Each side has the identical image offset 90 degrees from each other
The puzzle is then cut from both sides so it's impossible to tell which side is which!
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!
Each side has exactly the same 'Balloons' artwork and it’s impossible to tell which side is which - it will really have you scratching your head! Though it has only 529 pieces, it will feel more like 4000!
