I made this puzzle following Scojo's prompt to use indexing (here in the form of numbered rooms) along with some sort of lying clues.

  • Normal sudoku rules apply.
  • Spaces outside the grid are numbered room clues, they contain the same digit as the digit placed in Nth position looking into the grid in the row/column, where N is the digit in the first position.
  • For the following clues two instances of them are correct and one is false: Cages, Quadruples, German Whisper, Renban, Black dots, White dots, X.
    • Cages: digits may not repeat in a cage and must sum to the indicated total.
    • Quadruples: digits in a big blue circle must appear in the surrounding four cells as many times as they appear in the circle.
    • German Whisper: adjacent digits along a green line must have a difference of at least 5.
    • Renban: digits on a pink line are a set of consecutive numbers in any order.
    • Black dots: digits joined by a black dot are in a 1:2 ratio.
    • White dots: digits joined by a white dot are consecutive.
    • X: digits joined by an X sum to 10.

I don't think I can wrap my head around lying puzzles too well yet..
that puzzle was terribly hard for me, to a point where I even doubted that numbered rooms were to be trusted (but the rules said so imho) and
well I need a therapy doll and a cozy hiding blanket to explain.. let's just say
"what an experience" ;-)
