Good skill game for in between

Here you have 30 cardboard cards that all auweisen something elsewhere a punched hole. Painted the little caterpillar who symbolically eats its way through food each. Challenge is to stack the cards to each other so that the hole of the small card auzulegenden seen through the caterpillar of the underlying map. Real difficulty here is that the whole stack rests on a small wooden cylinder and threatened sooner or later upset if you are not careful!

I think that's a nice idea and well implemented beautifully. Of course, it is not a game that captures a days and hours, but for a short, exciting game in between (10 minutes), it is always good.
It trained in my view not only the motor skills of the fingers and hands, but also 3-dimensional imagination, because you just always have to keep the whole stack including wooden cylinder eye so that it does not tip over.

The age from 4 years I think is true.
