For this puzzle, make the words "Rob Roy" with a line running directly through the center of each word as in the illustration below without moving the pencil from the paper or crossing a line, or going over any line twice.

will reveal answer picture in a day or 2, thanks.




























yes…..
this is maybe the cooler puzzle i have ever saw, it is hard, but i liked very much, i think this can be the solution( explain it is harder than do it):
Assumptions:
1) SE= exterior side of the letter, SI= interior side of the letter, L= the line that goes through the letters and its not part of the letters
2) F= foward, U= up, D= down, B=backward
Explanation:
the first thing that goes is the direction and then the part of the letter that i am going with the pencil now begin in the line before entering the first R in “rob”
example:USE= you are going up in the exterior side of the letter
1) FL
2)(In the first R)= (USE ,FSE, DSE)-> (up outer semi-circle),LB,(USI,BSI,DSI)–>( up inner semi-circle), BL,DSE,FSE,USI, FSI, DSI,FSE,USE,FL (you has drawn the first R and are in the line going to the O)
3)(In the O)=(USE,FSE,DSE)->(up outer semicircle),BL,(USI,BSI,DSI)->(up inner semi-circle),FL,(DSI,BSI,USI)->(down inner semi-circle), BL, (DSE, FSE, US)->(down outer semicircle),FL (you has drawn th O, and are in the line going to B)
4) (In the B)=USE, FSE, DSE, BL, USI, BSI, DSI, FL, DSI, BSI, USI, BL, DSE, FSE, USE,FL ( you has drawn the B and are in the line going to the next R)
5) (In the second R)= the same that in 2
6)(In the second O)= the same that in 3
7)(In the Y)–> (this letter was by far the harder one for me) USE(diagonally),FSE,DSI(diagonally),BL,DSE,FSE,USI,USI(diagonally),FSE,DSE(diagonally),DSI,FSE,USE,FL ( you finished)
While doing this explanation i learn something Napoleon said long ago “a picture worth more than a thousand words”, he was so right.
not as difficult as i thought it would be. you really only have to figure out 3 letters, as the R and B are pretty much the same. kind of a long-winded solution, so im not gonna elaborate…
Here is my answer..
It is in a Quicktime Movie, drawn by me.
Hope you all can see it!!

got it, easy peasy
You can see 4 different ways of spelling this word here is the first,
here is the second,
here is the third,
and here is the fourth.
Don’t know how to show each line, but I can indeed do it.
Another way of doing the ” Y ” following the assumptions in my last comment is this:
USE-> ( LEFT EXTERIOR “\”), FSE->(LEFT UP “-”), DSI-> (LEFT INTERIOR “\”), BL->(“-” NOT PART OF THE LETTER), DSE->(LEFT EXTERIOR “|”), FSE ->( LEFT DOWN”-”), USI->( LEFT INTERIOR “|”), FL -> (“-” NOT PART OF THE LETTER), DSI-> ( RIGHT INTERIOR “|”), FSE-> ( RIGHT DOWN “-”), USE ( RIGHT EXTERIOR “|”) , BL -> (“-” NOT PART OF THE LETTER), USI-> (RIGHT INTERIOR “/”), FSE->(RIGHT UP “-”), DSE->(RIGHT EXTERIOR “/”), FL-> (“-” NOT PART OF THE LETTER).
YOU FINISHED
i think this explanation with the simbols is more easy to understand, the other way i explaned before for the Y i think is possible to, i draw it both ways and both seems to work.
I explained only the Y because it was the harder to understand the way i draw it the first time, but both ways i was able to draw it without breaking the rules of the problem, i liked this problem very very much
ups i miss a BL in my first explanation of the “Y” before the DSI, (sorry ).
when it says you can’t cross a line, what does that really mean?
and I wanted to point out that this is the 145th brain teaser on smart-kit.
My Gosh, Suineg!! We’re going to have to buy you a graphics pen & tablet! : )
Riyad-great job with the Quicktime movie; much easier to see than the way I was going to show the answer.
Ian: Haven’t forgotten, I’m still saving it for 200 : )
Thanks RK.. It would have been nicer had I had a tablet.
For whoever is interested, I used the mouse and photoshop layers. Then I opened those layers in Photoshop Image Ready and did the animation there.
Cheers
Riyad
JAJAJA i know is even more complicated to understand it in words, but i could not put an image, because i was in the office and did not have any program to do that . :>(
