A Carnivore Did It! - PBF game 1

See A Carnivore Did It! - PBF recruitment and discussion for more information.

For collective scoring purposes, game 1’s players will be: @Whistle_Pig, @RossM, @Assussanni, @RogerBW, @InkyBloc, @COMaestro, and anyone else who joins in and posts a solution to case 1 before we move on to the next case (once the aforementioned have submitted their answers).

The minimum solution is the name of the culprit(s). If you wish to use a timer then also provide the relevant time bracket (or the time itself). Feel free to include your reasoning, but this is not required. If you choose to pass, just write pass as your solution.

Before you submit your solution, highlight the text and use the “Hide details” option in the options menu (the + sign in a circle) to prevent spoilers for other players.

Summary

Shark - Iguana’s statement must be false - if a Herbivore did it, then one BOTH of Shark’s and Panther’s statements must be false and that isn’t allowed. Therefore following Peacock’s statement of the culprit being taller than 190cm, it has to be Shark.

Possible culprits if each statement is true:

  • A: A C D
  • B: B C
  • C: D
  • D: A B D

The only one that appears in exactly 3 lists is D, so Shark did it and B is lying.

I had to read the rules first oO and it took me a minute to find the statement that there is 1 lie.

Iguana is lying. (Either Panter or Iguana have to be lying because they have mutually exclusive statements.)
Shark is the culprit. (If Peacock tells the truth, there is only one possible culprit taller than 190cm → Shark)

Sounds like a really fun game. But I have no idea with going to that work event that I will have time to post solutions. I will try to because I love deduction puzzles but…

Took 1:01. Shark did it, Iguana is lying.

With a single lie situation like this, I basically just try each set of 1 lie + 3 truths, because all but one are going to fail in some way, so the first one that doesn’t fail is what I’m going to go with.

Shark is the culprit, and Iguana is lying.

  • If panther is lying then peacock must also be lying.
  • If if peacock is lying then shark didn’t do it, but shark’s statement absolves peacock, and panther and iguana’s statements exonerate each other.
  • If shark is lying then peacock must also be lying.

Therefore, iguana is lying. This means peacock is telling the truth leaving shark as the only culprit, which is not contradicted by panther or shark’s statements.

Good work, squad; no one tripped at the first hurdle. That criminal barely had time to commit a crime before you’d solved it. The commissioner rates your performance at a very impressive 97%!

But there’s no time to celebrate – we have another case on our hands!

Shark is the culprit, and Panther and Iguana are lying.

If shark is lying then panther is telling the truth, but iguana and peacock’s statements would then require either zero or two culprits to have one be lying and the other telling the truth.

Hopefully not brain fuzzy, as I just got up.

Shark is the suspect again, this time Iguana and Panther both are lying.

Shark did it. Racial profiling innit?

  • exactly one of pa and sh is true, so that excludes pa/sh true and pa/sh false.
  • if it’s pa and ig true, possibilities are pa+ig, but pe false indicates it’s pe. Inconsistency.
  • if it’s pa and pe, it’s pa and ig, but ig false indicates it’s pe. Inconsistency.
  • if it’s ig and sh, there’s no overlap between the culprit sets. Inconsistency.
  • if it’s pe and sh, sh is the culprit, and this is the only consistent result.

(But this kind of exhaustive analysis clearly isn’t fast enough. Or perhaps I’m just too hot.)

Shark did it again, Iguana and Panther are lying.

Just trying out possibilities again, only two this time: Either Shark is lying or Panther is. Then the other two fell into place off of that.
