Syllogism (2T1L + Dynamic Fog)
(Published on 27. September 2026, 20:25 by ViKingPrime)
PUZZLE:
RULES:
Normal Sudoku rules apply.
Normal German Whisper (green), Entropic (peach), Modular (teal) and Region Sum (blue) line rules apply.
Normal Kropki, XV, Evens, Arrow and Double Arrow rules apply.
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.
The puzzle is partially covered in dynamic Fog. Entering enough correct digits in cells will reveal more of the puzzle (no guessing is required).
An expanded ruleset is provided below.
INTRODUCTION:
You aren't seeing double... this is indeed a tweaked version of a previously released puzzle. I was convinced to repost it, with optionality for
an accessible version, a new recommendation for difficulty and to make the ruleset more explicit (as the previous version seemed to have rubbed people the wrong way). I hope this newer model makes up for any previous frustrations.
Have fun!
The
Two Truths and a Lie Series
EXPANDED RULES:
Fill the grid with the digits 1-9, so there are no repeats in any row, column or 3x3 box.
Digits along a green German Whisper line must differ by at least 5.
Each set of 3 digits along a peach Entropic line must contain one low {1, 2, 3}, one medium {4, 5, 6} and one high {7, 8, 9} digit.
Each set of 3 digits along a teal Modular line must contain a digit from a different remainder group - {1, 4, 7}; {2, 5, 8}; and {3, 6, 9} - when divided by 3.
Box borders divide a blue Region Sum line into segments of equal sum.
If separated by a white dot, digits are consecutive. If separated by a black dot, one digit is double the other [1:2]. Not all dots are necessarily given.
If separated by an X, digits sum to 10. If separated by a V, digits sum to five. Not all such clues are necessarily given.
A grey square indicated an Even digit.
Digits along an Arrow sum to the attached circle.
The sum of the digits along a grey Double Arrow line equal the sum of the two attached circles.
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.
The puzzle is partially covered in dynamic Fog. Entering enough correct digits in cells will reveal more of the puzzle (no guessing is required).
Solution code: The digits along Row 3, left to right.

What a beautiful, clever puzzle! It was not at all easy but all the deductions were fair. I enjoyed it a lot.

I completely forgot the one rule I needed to solve the end, it was making me crazy.
Great ending!

Just re-solved this puzzle and still very entertaining for me! Don't know what felt wrong for people who solved the previous version. A very fun (and funny) showcase of your setting style. Thanks :)
