Hint Switchboard
Every solution to the riddles you solved revealed a number or a colour. The switchboard that you see up there looks very antiquated. It seems that years ago each of the fields displayed a number. On the field in the left top corner one can still recognize a faint “1”. Which numbers belong to the rest of the switchboard’s fields?
By the way: the switchboard contains 9 fields- so, hopefully you also solved 9 riddles 😉
