For an upcoming major puzzling event, I was honored with the task of creating one of the puzzles which will be presented. I decided to go with a variation of Einstein's puzzle. I selected four countries (Netherlands, France, Hungary and Lithuania), and invited two people from each of them.
I practiced my greetings in the respective languages before I met them, so I could give them a warm welcome. To my surprise, however, some of the guests didn't actually speak the language of the country they came from...
Well, I guess it just adds another layer to my puzzle. Luckily, it seems the languages correspond perfectly to the countries (i.e. Dutch, French, Hungarian and Lithuanian), and there are exactly two speakers of each language!
Anyway, to get to my puzzle: I decided to ask them to make a couple of statements, which would then allow the participants of the event to figure out where all of the guests came from and which languages they spoke.
In order to not give it away (and to ensure the participants could actually understand them), all the statements would be made in English. I decided to do a test round before the real event, and got the following statements:
Carl Elav: Ms. Klechter is from France
Ms. Klechter: Kifca Zagó is from the Netherlands
Prof. Iglav: I'm from the Netherlands.
Stan Elav: I know Dr. Cedric is not from Hungary
Dr. Cedric: Lisa Chever is from France.
Rita Steir: Frau Pinot is either from Hungary or Lithuania.
Kifca Zagó: I know Rita Steir is afraid of water, and thus has never been to the Netherlands.
Lisa Chever: Prof. Iglav is not from Hungary
Frau Pinot: I'm from Lithuania
... Well. It seems we have a few problems. First of all, none of the guests said anything about what language they were speaking. Secondly, we somehow ended up with 9 people speaking instead of the 8 I invited. Thirdly, I have an awful gut feeling that some of them actually weren't speaking the truth (and from experience, my gut feeling is usually pretty accurate). And last, but not least... I have a terrible memory. I don't remember which guest came from which country, or even which guest wasn't invited at all, and I lost my notes.
I've accepted the fact that we might never know where the uninvited guest came from, but I do hope that with the help of you smart people we can figure out:
- Where the other guests came from
- What language everyone speaks (including the uninvited guest)
- Who tells the truth and who is lying
It might seem like an impossible task, but my gut feeling tells me there should be some people here who should be able to do it. Please show me my gut feeling is right again - I'd love to present it at the event!
