Had a lot of fun helping ViKingPrime with this liar puzzle using some newer line constraints. Here are three other excellent puzzles that preceded it, using the same ruleset:

Shenanigans by Jay Dyer

Fourberie by ViKingPrime

Chicanery by ViKingPrime

Rules:

  • Normal sudoku rules apply.
  • Kropki: White dots separate two consecutive digits; Black dots separate two digits where one is double the other [ratio of 1:2] (not all dots are given).
  • Palindrome (slate): Digits along a Palindrome line read the same from both directions (e.g. 153747351).
  • Same Difference (turquoise): Every pair of adjacent digits on a Same Difference line has the same difference (this value may be different for different lines).
  • Zipper (lavender): Digits an equal distance from the center of a Zipper line must sum to the digit in the middle of that line.
  • MODIFIERS:

  • Shenanigans!:: Each line is one of the above constraint line-types but some are lying to you (i.e. they must satisfy one of the other line-types and not the presented colour). The wrong-coloured lines are exactly those lines which have the digit 'D' on them ('D' must be determined by the solver).

Honestly one of my favorite puzzles of yours yet. It flowed very nicely and never got stuck for too long at one place. The ricocheting between different parts of the puzzle was also a lot of fun!

Marty: this puzzle was largely set by VikingPrime, so you may enjoy checking out his other puzzles if you haven't already

The two kropki dots are amazingly clever!
Everything flows so nicely - a truly enjoyable puzzle.

I like the shenanigans modifier. The middle part of this was best, but all of it was good.

Terrific! Such shenanigans were had

Incredible logic from start to finish! Really liked how many different digits were able to be the sus one until the big reveal :)
