Unsquare Dance (Arrows + Various Lines)

(Published on 4. May 2026, 08:10 by damo_89)

Hopefully something relatively approachable. Honestly, probably more a 1.5 star for experts, but the sheer volume of rules grants an extra star! The rules are long but all rules are standard. Good luck!

  • Normal sudoku rules apply: Place the digits 1 to 9 once each in every row, column, and 3x3 box
  • Diagonal: The positive diagonal, marked with a blue line, contains a set of digits 1 to 9
  • Arrows: Digits on an arrow sum to the digit in the attached circle
  • Renban: A magenta renban (R) line contains a set of consecutive digits in any order
  • Entropic: Along a peach entropic (E) line a run of three cells contains one low digit (1, 2, 3), one medium digit (4, 5, 6), and one high digit (7, 8, 9)
  • Modular: Along a teal modular (M) line a run of three cells contain different remainder when divided by 3, i.e. one digit from (1, 4, 7), one from (2, 5, 8), and one from (3, 6, 9)
  • Nabner: On a gold nabner (N) line no two digits anywhere on the line may be consecutive with each other
  • Parity: On a red parity (P) line adjacent cells contain one even and one odd digit
  • White Kropki: Digits separated by a white dot are consecutive. Not all dots are necessarily given

I think the two star rating is justified. The break-in is harder than the rest and you probably need a bit of experience to be able to solve it quickly - in which case however you can be quick.
