How to solve

  • Latin square: Every row and column holds each height from 1 to N exactly once.
  • Count what you see: An edge number is how many buildings are visible looking in from that side.
  • Tall hides short: A building is hidden if a taller one stands in front of it.
  • Blank edges: An edge without a number gives no clue.
