Thanks for another great year Matt! I agree about the step up in difficulty. I found the final logic puzzle, in particular, very difficult, and definitely got frustrated at times! I even tried to resort to a brute force solution in Python since there are only 10,000 possible solutions, but there's a trap baked in related to the clues referencing themselves that made this not work out for me! In the end, I ended up solving it using good old manual reasoning with a bit of trial and error :-)
