PolyLine Loop (with ChinStrap)
(Eingestellt am 26. Februar 2025, 15:06 Uhr von gdc)
This puzzle was created as a collaboration with ChinStrap for a setting challenge by aqjhs. The challenge was to make a puzzle that uses polylines. See below for an example puzzle. Thanks to the CtC fan discord for testing and feedback. Hope you enjoy!
- Normal sudoku rules apply.
- Loop: Draw a 1-cell wide loop of orthogonally connected cells. The loop can't touch itself, not even diagonally. Box borders split the loop into segments. Each segment has exactly one of the 3 segment types below. Adjacent segments have different types.
- Sum Segment: Digits on the segment sum to 17.
- Whisper Segment: Adjacent digits along the segment differ by 5 or more.
- Renban Segment: Digits on the segment are consecutive when sorted.
- Odd Lots: A digit in a circle is on the loop and counts the number of odd digits on its segment.
- Even Lots: A digit in a square is on the loop and counts the number of even digits on its segment.
Example Puzzle
This 6x9 grid contains a loop that satisfies the rules above. The segments have been colored in green (whisper), pink (renban) and blue (sum). Adjacent segments (that "touch" at a box border) have different types. Digits in circles count the number of odd digits on the segment, but don't have to be odd themselves. The same is true for squares and even digits.
Lösungscode: Digits on the loop in column 9, top to bottom.

Very nice puzzle. I love seeing the logic of polylines in new and original ways. This construction is wonderful and very entertaining.

Add the following to the rules (in SudokuPad) to stress things that are easy to miss (or make wrong assumptions about).
Remarks: Digits in circles don't have to be odd. Segments that touch have different types.

Brilliant. Was stuck forever until I reread the rules and realized two types can't be consecutive. Then smooth sailing

Instantly a fan of polylines after this. A lot of the boxes felt like mini games within the overall puzzle, which kept the whole puzzle engaging and refreshing.
