Bunker

The philosopher Jakob Friedrich von Reiff, born on 23.12.1810 in Vaihingen an der Enz, has long been dead, but one of his lost original books has now been discovered in his birth house. But as so often, the "Gambler" was faster again and took possession of the work. He threatens to destroy it, should the city not face his "Gamble". If you beat him in his puzzle game, he will return the book - otherwise he will burn it. The game begins in Pulverdinger Forst, between Ludwigsburg and Vaihingen Enz, which is known for its many bunkers from the Second World War. What will happen there?
