The 27 Club (with sujoyku)

(Published on 7. July 2025, 05:16 by mellowrobinson)

When I half-jokingly suggested this title for his one-total Killer series, sujoyku enlightened me to some of the interesting properties of this number, and asked me to collaborate on it. Together we found out just how weird and wonderful this Killer total can be. :)
  • Normal Sudoku rules apply, i.e. each row, column, and 3x3 region has to contain the digits from 1 to 9 once each.
  • Killer cages: Digits in a cage do not repeat and must sum to 27.

This was a blast! Not a single celebrity was harmed in the creation of this puzzle, maybe!
