Today one of my classmates showed everyone this puzzle that he had been trying to solve for a very long time. The rest of the class I tried to solve it and since I got home I have been trying to solve it but still nothing.

this is the starting area, what you have to do is draw a continual line through all the lines in the starting area without your own line crossing itself, your line can never cross the same line twice

We can do it right 🙂
 
OMG! i spent like 4 years trying to solve this one.. and no its cant be a straight line... i know how its solved but dont wanna ruin it

Are you saying the left most vertical line would be two lines, because it is dissected by the middle horiztonal line?

I remember seeing this puzzle in school years ago. Someone said they solved it by making the puzzle into a 3-d puzzle. I don't know if that's true or not, but he said that's the way to solve it.

any idea what they meant by making it into a 3d puzzle?
 
by regular means its not possible.. i started doing this puzzle in like the 4th grade and have been doing it for years... i know you have to somehow use the uppper center line to solve it though

No you didn't. Its a mathematical impossibility

something I had started to worry about, there are 3 boxes made out of 5 lines and that means that the line has to begin or end in one of them, that means that one box is left out.

still I think I remember seeing it solved when I was younger
 
What does cross the other lines and not go over them mean?

Edit: Nevermind, I see. I also think I remember reading there is no solution.
 
you remember seeing it solved sort of like the way i tried to do it.. the trick is that upper center line... i know exactly what it was but its been at least 5 years last time i saw the answer..oh well

No, I remember that there is a solution... '

Nope, I was wrong. there is no solution:

Unfortunately, this, one of the most popular classic puzzles, has no solution. At least, one wall always will be left unpassed.

It was easy proved by Martin Gardner. The proof (adopted to our case with the walls and rooms) is as follows:
<<A continuous line that enters and leaves one of the rectangular rooms must of necessity cross two walls. Since the three bigger rooms have each an odd number of walls to be crossed, it follows that an end of a line must be inside each if all the 16 walls are crossed. But a continuous line has only two ends, so the puzzle is insoluble.>>
