The exact solution is this.

the question poses one against the other, meaning the answer will lead you the opposite door.
door 1 = Hell
door 2 = Heaven
The question is this
" If You were the other guard, which door would you tell me leads to Heaven ?"

The truth teller would answer :
" I would tell you door 1 "( which would be hell, as the liar would lie, and so must the truth teller in this case since he is put in place of the liar ! )
IN THIS CASE YOU TAKE THE OTHER DOOR = Heaven

The Liar would answer :

"I would tell you door 1 " ( which again would be hell, as the truth teller would say door 2, but the liar would lie ! )
IN THIS CASE YOU WOULD TAKE THE OTHER DOOR


The opposition technique is great, but unfortunetly very confusing.. even when you know.

Here is a nice riddle for fun:


A Man walks into a hospital to visit a patient and the nurse asks "Are you a relative?"
The man answers with the following statement:

" Brothers and sisters I have none, BUT this mans Father, is MY Fathers son ! "

so who is he going to see and what is his relationship to this patient ??



Have fun..

Everyone seems to be missing Gerald Kosky's version called To Tell the Truth from the Vol 1 No 6 1978 issue of Apocalypse. I believe this predates every source mentioned yet.

For the logic puzzle alone, with no mentalism, see the wonderful book The Lady or the Tiger by Raymond Smullyan. Smullan gives the whole idea of truthtellers and liars a a fascinating and fun treatment.

For information Marc Paul has an absolutely incredible Truth teller / Liar premise effect, entitled True Lies. From what I understand, it has not yet been published, but Im sure if enough people pull on his sleeve he may release it. It really is a great piece of thinking!

Okay: By moving the first or second "o" in the second word to precede the "n" in the first word, then moving the "w" from the end of the first word and making it the first letter of the second word, then moving the "d" from the start of the second word to the end of the second word, you now have "ONE WORD." Yes?

There is one called Liars! in Phoenix no 90 from 1945 by Tommy Dowd. It's a different logic though. You need a p**k.

An early version of this type of thing as a mental effect is Gerald Kosky's "To Lie or, Tell The Truth?" in the book "The Magic of Gerald Kosky" (p.131).

Whilst I don't have it to check, there may also be something in Jack Yates' "Clue -And Other Mysteries".

Where did you hear about this, Ringo?
muhahahah!

...and on a topic VERY much related, but I'll call it a side note, my book THE SAFWAN PAPERS will be released after this weekend...(hopefully both eBook AND printed format...but for certain in printed.) My BOHT routine is included...it is not a logic puzzle. It is...something different.

A great premise that we all love to explore, isn't it...? Despite it seemingly being only a 50/50.

I've always been a big fan of the "liars and truth-tellers" logic puzzles (or the "knights and naves" as coined by Raymond Smullyan). The two door/path puzzle is a classic. But am I to understand that the puzzle itself is being presented as a bit of mentalism? Or is the puzzle only the premise and there's more to it?

Where can I find BOHT? I didn't see it on his website.

Hi Larry..

BOHT is a methodology/routine I am releasing in my book THE SAFWAN PAPERS. It is not a logic puzzle, but fits in this genre of effect.

I'll be posting in a seperate thread when this is ready to go...hopefully in a day or so.

Thanks for the interest.
Bryn
