Rules
- Each row and column holds 1–N exactly once, representing building heights.
- An edge number counts the buildings visible from that direction.
- A taller building completely hides every shorter one behind it.
How to start
A 1 means the first building is the tallest
Seeing only one building forces that first cell to be N.
An N means strictly increasing
Seeing all N buildings means the row runs 1, 2, 3 … N.
Lean on the Latin square
Once heights are constrained, row and column uniqueness fills the rest quickly.
Where players get stuck
- Counting "how many are taller" instead of "how many are visible".
- Forgetting a tall building only hides shorter ones — taller ones behind it still count.
