Fragmented Machinations
(Published on 26. December 2025, 14:56 by Andrewsarchus)
Rules:
- Normal Sudoku rules apply
- Regional Constraints:
- Each constraint type may contain no repeated digits anywhere in the puzzle.
- (Does not apply to Full Rank, but does apply to the digits on the Tentropy Line which double as Full Rank clues).
- Tentropy Lines (beige):
- Every set of 4 adjacent digits on a Tentropy Line must contain a digit from each of the X-pair (ten-pair) subsets of {1,9}, {2,8}, {3,7}, and {4,6}.
- A 5 may not appear on a Tentropy Line.
- Full Rank:
- A value in an external cell represents the rank of the number formed by reading the digits in that row or column from that direction, where (1) is the lowest such row or column and (36) is the highest.
- The 36 numbers are distinct - no ties.
- German Whisper Lines (green):
- Digits next to each other on a German Whisper Line must differ by at least 5.
- Thermometers:
- Digits on a thermometer must strictly increase from bulb to tip.
- Cages:
- In this puzzle, cages are just there to identify another set of cells subject to the Regional Constraint.

About the gentlest full rank hybrid I've seen. Very nice.

Great use of the "no repeats" constraint. Thanks!
