Shamelessly copied from the website:
At our museum, you can enjoy over 150 fascinating and lovingly restored pinball machines from the 1930s to the present. And because pinball machines are not only objects of art to be looked at, you can actually play most of them at our museum. Additionally, there is lots of information about the machines, their history, makers and technology.
Visit us – we’re only about an hour northwest of Frankfurt International Airport
There are too many nerdy spots to show you (Over 1000!) in the current map view.
