Confusion

If you like puzzles this deserves your time. If I was stuck I would take the puzzle to the pub where the collective minds would eventually work it out. One puzzle toward the end completely stuck me and my fellow drinkers. We agreed that the internet would not be used and for a few weeks we made no progress. Then someone unrelated to our boozy circle walked past the drawing of the puzzle and said the answer. Just like that. Annoying because they did, great because it meant we could move on. Completed it was and I have found nothing as good since.
