Bats (Zipper/Entropic/Modular Lines)

(Published on 29. January 2025, 23:23 by damo_89)

This is my submission for the latest setting Saturday prompt by Scojo, this called for entropic and modular lines to be used. I've added a brown line which is both entropic and modular, and also zippers. I've been underestimating my puzzle difficulties recently so I'm pitching this initially as a 4 star but I hope people find it easier. Good luck!

  • Normal sudoku rules apply: Place the digits 1 to 9 once each in every row, column and 3x3 box
  • Entropic Lines: Any run of 3 digits along a peach entropic line must include one low digit (1, 2, 3), one medium digit (4, 5, 6) and one high digit (7, 8, 9)
  • Modular Lines: Any run of 3 digits along a teal modular line must include one digit from each of the modulo 3 sets, i.e. one from (1, 4, 7), one from (2, 5, 8) and one from (3, 6, 9)
  • Combo Line: The brown line must adhere to both entropic and modular rules, above
  • Zipper Lines: Digits an equal distance from the center of a lavender zipper line must sum to the digit in the center
