Watchtowers
(Published on 6. July 2025, 06:15 by Belamis)
Sudoku: Normal Sudoku rules apply.
Arrow: The sum of the digits along an arrow is equal to the digit in the connected circle.
Each digit in the grid represents the height of a building in its cell. Taller buildings obstruct the view of shorter ones behind them.
Each Square "Watchtower" must see every digit 1-9 at least once either horizontally, vertically, or diagonally. Watchtowers do not count as being seen by themselves, or by other Watchtowers.
Solution code: Row 8

Starts simple but becomes sophisticated as it goes. Only 3 difficulty for me but very intriguing.

Excellent construction! After a quick and easy start the rest of the walk along the watchtowers got harder and harder - well, for me at least. But I enjoyed each single step. Thank you very much for creating and sharing this gem.

Nice puzzle. Definitely not hard after you've done the initial evaluation how to make the watchtowers see every digit 1-9

Wonderful ruleset and puzzle with quite minimal clues. Only 2-2.5* for me. Thanks!

An absolutely fantastic puzzle. I had several minutes of utter confusion, followed by an "Aha!" moment that unlocked the whole thing. Super smooth, super brilliant.
