Rules:

  • Normal sudoku rules apply.
  • Tentropy Line: Every set of 4 adjacent digits on the hollow peach 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. Digits on a line may repeat if allowed by other rules.
  • Parity Line: Digits on the thinner solid red line (the line running through box 7) must alternate between odd and even.
  • German Whispers: Adjacent digits on the green line (with white dots) must differ by at least 5.
  • Region Sum Lines: Region borders separate the thicker blue lines into segments of equal sum.

All feedback (positive or critical) appreciated!

Solution code: Box 5 in left to right reading order (9 digits)

Superb puzzle! I loved the break-in idea and the wonderful interplay of Tentropy with other "aspects" of digits. Thank you for setting and sharing this gem, ChinStrap!
