9-to-4: A Better Way to Make a Living

(Published on 24. September 2026, 04:46 by lgastako)

While making my 9-to-5 puzzle I ended up having some ideas that resulted in this puzzle. And I think 9-to-4 would be a better standard work day anyway :) As always, feedback is welcomed and encouraged.

P.S. This puzzle was initially activated with the link to the original 9-to-5 puzzle but with the rules for this one included. I apologize to anyone that encountered that (confusing) version!

  • Normal Sudoku Rules: Fill each row, column, and 3x3 box with the digits 1-9 once each.
  • White Kropkis: Digits in cells separated by a white dot are consecutive.
  • Thermometers: Digits along a thermometer strictly increase from the bulb end.
  • Renban: Purple lines contain a non-repeating set of consecutive digits in any order.
  • Killer Cages: Digits in cages must not repeat and must sum to the number in the upper left corner of the cage (if present).
  • Region Sum Lines: Box borders divide blue region sum lines into segments, each of which have the same value.
  • All lines, thermos and cages must be populated with only the numbers from 4 through 9.
