Pinocchio: a Gentle Liar

(Published on 19. September 2022, 20:57 by thoughtbyte)

This is inspired by the Two Truths and a Lie style puzzles of zetamath, Niverio, ICHTUES, and SirWoezel (Thank you all, especially zetamath for introducing this beautiful idea). I love this kind of puzzle but they are quite difficult 4 and 5 star puzzles. My goal was to set a gentle liar puzzle so that solvers who have not been able to try the more difficult ones can engage with this wonderful ruleset, and that more experienced solvers will enjoy as a quick, fun puzzle.

I believe this puzzle is 2.5 stars for difficulty. Feedback is always appreciated. Have fun!

Normal Sudoku rules apply. Additionally:

Each of the following standard clue types occurs exactly three times in the grid: white dots (consecutive), black dots (ratio), arrows, Xs, Vs, X-sums, palindromes (gray), renban (purple), German whispers (green), evens (gray squares), and maximums (gray squares with arrows pointing outward). Note: the gray maximum squares have arrows pointing in all 4 directions, some are covered by Kropki dots. Rule details can be found below.

For each of those clue types, exactly two of the appearances of that clue are correct, and the other is incorrect. [A clue is incorrect if it is not fully correct. For example, an incorrect renban might have a subset of consecutive digits, but not all of them.]

Kropki pairs: cells separated by a white dot are consecutive, cells separated by a black dot are in a 1:2 ratio.

XV: cells separated by a V sum to 5, cells separated by an X sum to 10.

Arrows: digits along an arrow sum to the digit in its circle.

X-sums: clues outside the grid show the sum of the first X digits from that direction, where X is the first digit.

Palindromes: digits along gray lines read the same in both directions.

Renban: purple lines contain sets of non-repeating consecutive digits.

German Whispers: digits along green lines must differ from their neighbor on the line by at least five.

Evens: cells containing a gray square are even.

Maximums: digits in gray cells with arrows pointing outward are greater than all digits in orthogonally adjacent cells.

Solution code: Row 1, row 4.

I found this one to be the hardest of the bunch, for some reason; took three tries to finally crack it. To all the future solvers, if you find yourself breaking the puzzle - reset, rest and try again at a later point (a fresh pair of eyes helps a lot).

Amazing puzzle! I cannot wait for the next in the series.

Quite a nice and approachable use of the liar rules! The logic was satisfying and I was never stuck for too long. 3* difficulty for me.
