Slightly Wrogn

(Published on 24. January 2021, 16:19 by titus)

Normal Sudoku rules apply.

There are five standard rules appearing in this puzzle (details below). However, exactly one of each clue type is wrong (behaves as if it wasn't on the grid).
  • Killer Cages: Numbers in a cage sum to the digit in the top left, and digits cannot repeat within a cage. 1 of the 6 cages is wrong.
  • Arrows: Digits along the arrow sum to the digit in the circle. Digits can repeat along arrows (following standard rules). 1 of the 5 arrows is wrong.
  • Black Kropki Dots: Digits on either side of a black dot are in a 1:2 ratio. 1 of the 3 dots is wrong.
  • Palindromes: Digits along the thick grey lines read the same forward and backwards. Digits can repeat along palindromes (following standard rules). 1 of the 2 palindromes is wrong.
  • Skyscrapers: The numbers outside the grid represent how many skyscrapers you could "see" from that end of the given row/column, if each cell were occupied by a skyscraper whose height equals the value in that cell. 1 of the 2 skyscraper clues is wrong.
This puzzle is available on f-puzzles.com.

Solution code: Column 2 then Row 8 (18 digits, no spaces)

Made it in the first attempt, although I had the feeling that I could be on the wrong track until the end...interesting, enjoyable puzzle.

Interesting take on the wrogn concept. I liked it.

Enjoyable solve, but had to think carefully when found potential contradictions, was my logic wrong or was it wrogn... :)

Flows nicely - very enjoyable! I estimate the difficulty level rather at 2-3 stars, but that will auto-correct when enough people have rated the puzzle.
