Two Pieces of Paper

Postby kandalf » Thu Aug 14, 2008 5:02 pm UTC

Please note I did not come up with this puzzle, and the solution is available on the web - please refrain from looking it up and posting it here - solve it yourself!

I was presented with this problem this summer, and I enjoyed it a lot. I don't think it's too difficult.

I have recreated it on this page:
http://nicholasmeyer.googlepages.com/paper.html

And the original puzzle title is a hint, so I've put it in spoiler tags, use it if you'd like:
Spoiler:
Sixteen Blocks

Have fun!

I just got well and truly sniped. Well done.
Spoiler:
The two lists with crossed out words, along with the hint, suggest a boggle game between two extremely skilled players. Finding out the number of blocks for each letter wasn't too bad; finding the locations was a lot worse. A long analysis finally yielded:

Code: Select all

A A T O
N T S P
S O E S
W E R I

Or, any rotation or reflection. I'm pretty sure it's consistent with all the words listed. One place I might have gone astray: I assumed N did not touch P because there were no words sharing those two letters consecutively; however, I also can't think of any words off the top of my head with that arrangement, so I guess it's not necessary to separate them. I'm not sure if my solution is unique. (again, up to rotation and reflection)

Spoiler:
It doesn't matter whether you rotate or reflect the board, because the ANSWER IS POTATOES.
(∫|p|2)(∫|q|2) ≥ (∫|pq|)2
Thanks, skeptical scientist, for knowing symbols and giving them to me.

Other than the fact that
Spoiler:
"potatoes" is a word that can be found on that boggle board and which neither of the two players found,
I don't see how that's relevant, much less the answer. Enlighten?

Here's the reason...
Spoiler:
Follow the board you wrote in a spiral, you can get the whole phrase "AnswerIsPotatoes".

No chance I'd have ever seen that without yours and cauchy's replies though.

Yep, that's the answer.
Spoiler:
potatoes, that is. I spent a while before figuring out it was boggle, and I was able to use some educated guessing to go from there.

Well done!

Wow.

Having never played boggle and having no idea how it is played, I had no idea where to begin. I need to stop coming to topics like this.
My webcomic is made with 100% LEGO products and I think you should check it out.

Technically it can be done without a knowledge of boggle - an analysis of the duplicates of letters shows that there are only sixteen letters making up all the words, and then it's just an anagram. Made easier if you guess the first bit.
