Actually, it is not the same worldwide.
Czech GPS Maze EUROPE is different from the US version and from what I read from the GeoNord listing in Northern France, this might be a completely new one too. I haven't visited any, so I cannot tell if the US or EU versions are the same each time.
So we have at least 2, if not 3 versions, visit each one twice and you have 6 without being too bored. Personally I would even visit the exact same one 5 times if I want to have this badge. I have found dozens of trads along the road, they are also interchangeable and boring. ;)
