[This is a repost from our archives with new notes at the top (original post here): This very memorable Skyscrapers started by thinking about placing a lot of twos and placing a lot of “bigger than twos”. The puzzle got an extra level of attention in a “How to Build a City” post describing the construction/intended solution path at the same time which many people point to as one of their favorite early posts on the site. This style of general logic puzzle design is covered extensively in Puzzlecraft: How to Make Every Kind of Puzzle for those who want to practice making grandmaster puzzles for themselves.]
