This money box opens only if you have the ball successfully steered through the three-dimensional maze. Here you can ever get a little confused, since everything is made of transparent plastic. If the ball arrived at the right place, it pushes the bolt sideways and pushes the ball by means of a spring on the cover. On the package the way described, but first I could not accept this, because I was already messed up, and secondly, it would be too boring to follow him. It also works without. The tinkering is not super difficult because there is only one real way, the dead ends stand out very quickly as such. Nevertheless, it is a nice gag. Whether filled with money or a gift, the money box is definitely more original than the typical envelope!
