Stella posted a new challenge:

The fields above are mazes and you have to get to the field called "exit". 

The numbers give you the number of steps you need to go in a straight line to the next field.

Its more easy to solve the maze from the end.

Once you've solved it, read the letters from the below maze.

The result is "tunnelfiftyseven" and an escape tunnel from eastern berlin.
