So you think you know jigsaws...how about this one? No picture because ... well what help would that be? No solution because ... well how would that work? So the only way out is to stick with it .... and stick with it some more....and eventually like all good jigsaw puzzlers will tell you ...patience will win out. They were a bit of a craze in the US recently so we just had to give it a go and sure enough it is a great puzzle. If you think jigsaws are easy...think again - no picture, and because you cant tell which way is up with the pieces....a proper brain workout. It s only 24 pieces but do not be fooled ... since every piece can work upside down you can multiply the options and what you get is one tricky puzzle ... also a lot of fun though. Take the challenge if you dare...
