Hidden MEANing

(Published on 10. July 2025, 03:43 by antiknight)

Wanted to try setting a puzzle where no constraint type can have any repeated digits. Had some ideas using average arrows along with a couple of standard constraints. Hope you enjoy the puzzle, and feel free to leave a comment if you liked it!

Rules:
  • Sudoku: Normal Sudoku rules apply.
  • Arrows: The digits along each arrow must sum to the digit in the circled cell.
  • Average Arrows: The digit in the golden circle is the exact average of the digits along the golden line.
  • Kropki Pairs: A black dot between cells indicates cell values with a 2:1 ratio. A white dot between cells indicates cells with consecutive values. Not all dots are shown.
  • German Whisper Lines: Adjacent digits on each green German whisper line differ by at least 5.
  • Ten Lines: Digits on gray lines form one or more contiguous, non-overlapping groups that each sum to 10.
  • Constraint Regions: Each constraint type may contain no repeated digits anywhere in the puzzle. E.g. a digit on one German whisper line cannot appear on another.
  • Lines and arrows do not branch or overlap with each other.
  • Dynamic Fog: The grid is partially covered in fog. Placing a correct digit may clear fog elsewhere in the grid.
