So why is Wasgij so popular? with traditional jigsaws the puzzler builds the image that they can see on the box. With Wasgij they have to build an image that is different to that shown on the box. Although we give a few clues, Wasgij really challenges the puzzler to use their imagination. Put that together with great drawings and pictorial humour and it is no surprise that Wasgij has topped the jigsaw puzzle charts for so many years.
