The Straight and Narrow (Two Truths and a Lie)
(Published on 27. April 2026, 12:00 by ViKingPrime)
PUZZLE:
RULES:
Normal Sudoku rules apply.
Normal German Whisper (green), Parity (red), Region Sum (blue) and Renban (pink) line rules apply
(digits along a green German Whisper line must differ by at least five [5]; digits along a red Parity line alternate between odd and even; box borders divide a blue Region Sum line into segments of equal sum; digits along a pink Renban line form a set of consecutive, non-repeating digits in any order).
Normal "Diagonal" rules apply
(digits cannot repeat along a thin blue line that spans the grid, each of which passes through the central cell without turning).
Each of the above standard clue types contains Two Truths and a Lie. Each occurs exactly three times in the grid; for each, exactly two of the appearances of that clue are correct and the other is incorrect.

Love figuring out lying clues, still one of them took me unnessecarily long time because of a mistype. Still had a great time. Thanks!

What a great puzzle! The break-in was a bit tricky, and the rest flowed really nicely (with a notable difficulty spike near the end, at least for me!)
