Puzzles are fun, the difficult it is, the more interesting the puzzle, but there are already four threads on this topic. I don’t think there is any reason to start another. You could continue this discussion in the most recent thread.
I did try and search the word puzzle from forum's Home Page. I got 2 hits, One post was completely irrelevant to this puzzle and one random puzzle post from year 2014. Hence I decided to post it in a new one!
I agree that Puzzles are fun, the difficult it is, the more interesting the puzzle
If mods think this post need to move please feel free to do so!
