HOW TO PLAY

1. Every square holds a tower. On a 4 by 4 city the towers are 1, 2, 3 and 4 floors tall.
2. Each row and each column has one tower of every height, so no number repeats.
3. The numbers round the edge say how many towers you can see looking in from there. A tall tower hides all the shorter ones behind it!
4. So a 1 means the tallest tower is right next to it, and a 4 on a 4 by 4 city means the towers go 1, 2, 3, 4.
5. Tap a square, then a number. Turn on ✏️ Notes to jot down maybe-numbers. An edge number turns green when its line is right.
6. Solve it without hints for 3 stars ⭐⭐⭐. Every puzzle has exactly one answer.
