Under Siege - SE Tower
(Published on 11. April 2025, 03:14 by Arlo Lipof)
A German fortress is being attacked from all sides by a ruthless enemy. Despite their limited resources, the archers defend their castle as well as they can. To survive the siege, they have four secret passages to sneak out of the fortress past the enemy's lines.
As you can see below, the puzzle Under Siege consists of four Sudokus, one for each tower of the fortress. These Sudokus are based on the same constraints, but are all independent from each other. You can click on the images to navigate between the towers:
Rules:
- Sudoku. Normal Sudoku rules apply.
- Arrows. Digits along an arrow must sum to the number in the attached circle or pill (read from left to right). Digits may repeat on an arrow if allowed by other rules.
- German whispers. Any set of two adjacent cells along a green line must contain digits that differ by at least 5.
- Between (the enemy's) lines. Digits along a golden line must be strictly between the digits in the circled ends of the line.

These Sudokus are all approachable. Have fun!
Solution code: Row 1

WOW! Awsome series. Really enjoyed. For me the hardest one was easily NW. Took me over hour to solve.
A: Many thanks, kopo1, that’s very kind of you! I’m sorry that you struggled with the NW Tower. You may have overlooked a key step here, but I can assure you that it should take about the same time to solve each of the four Sudokus.

Just finished the whole x4 puzzle. Really amazing work!
So much fun to solve. All four puzzles felt so nice and challenging, but not in a hard way. There was always something to look at and wonder. No seeming dead ends and a truly clear path. Thank you so much for setting this!
A: Thank you very much for this delightful comment. You made my day!
