Slitherlink (Entropic Liars)

     Again, a slitherlink puzzle to showcase a type of clues : Entropic Liars. For this one, I used a combination of Entropy (Sudoku) and Knapp Daneben rulesets. Here are the rules :

Normal slitherlink rules apply, but clues may be liars. In each 2x2, at least:
- One number must be 1 lower than its actual value,
- One number must be a true value,
- One number must be 1 higher than its actual value.
No clue may be off by more than 1.

Slitherlink (Swapped Pairs)

     The variant Slitherlink (Swapped Pairs) was created by myself on the fly during a speed setting contest. The "Swapped Pairs" could work for a lot of puzzles, I think it has potential.

    Normal slitherlink rules apply. For each color, one pair of clues must have their values swapped while the other remains untouched. White clues behave normally.

    Note : the first puzzle has a disconnected purple pair in 2 corners of the puzzle. These 2 single cells are considered a pair.

    Second puzzle was the winner of the SSC (I labelled myself as ??? as we need to be anonymous for non-biased judging), the first one was made for this post.

    Thanks to Rook, Stef, Superrabbit and TwoHoleStraw for testing and feedback on 1st puzzle, and again Superrabbit for the SSC.
