Arrow Alignment
(Published on 29. October 2024, 00:12 by Elytron)
Introduction
This puzzle uses a new rule which Gnubeutel came up with, which I find very interesting to work with. I don't want to spoil too much, but the rule is a reference to the Mad Magazine Fold-Ins. If you want to learn more about the inspiration or want to get a better explanation of the rule, I suggest you check out the puzzle A Tribute to Al Jaffee.
Rules
- Normal Sudoku rules apply.
- Fold-In:
- The dashed red lines are folded onto each other so that columns 1, 2, 8, and 9 form a secondary grid. In this grid, all rules apply, except that regions and rows do not need to have all digits (it's a 4×9 grid).
- Arrows:
- Digits along an arrow line sum to the number in the attached circle.
Solution code: Row 1 from left to right (9 digits).
