The Abandoned Black Forest Hut

It's strange that you didn't know about this! Apparently you have an old relative who lived alone in a quaint forest cabin deep in the Black Forest... at least that's what it says in the crumpled letter he sent you before he emigrated to Canada. He has left you all his inheritance, which you can now search for in his forest cabin. Actually quite a nice thing ... isn't it? Have you inherited the sharp-witted genes of your relative and will you find his left-behind fortune? Will you prove to be worthy descendants? Since we don't know who already knows about the vacant forest cabin, you don't have much time for your search! Use the remaining 60 minutes to solve your relative's puzzles!
