Every Christmas my whole family tries to solve the Dr. Denker puzzle of the Dagblad van het Noorden (a Dutch newspaper). It’s tradition. This year I thought it would be cool to make a similar puzzle of my own. It took me a while, but it’s finished!
Take a look and solve the puzzle! The puzzle is in Dutch ;)
update: The solution.
of course, I also had to make the website for the puzzle, which was a puzzle by itself
