Extremely Tough Brain Teaser

You have to pass through each "gate" only once. The gates are just each interrior and exterrior line of the box. You can criss cross your lines, but you can't double over a gate. Apparently it took over 200 years for it to be solved. Check it out.

Edit: The bottom image is an example of a 'mess-up', with an x over the two missed gates.

Not sure I understand the task, I think I got it.

You missed one. Each perpindicular line separates the line into another "gate". There are "16 gates" in all.
 
So I took a look again when I got back from class. Didn't solve it. Agree that it's impossible without screwing with the rules, interpretation, etc.
 
It's impossible. 3 of the rectangles each have 5 "gates", and the outside area has 9. Whenever you enter an area, there must be a way to exit, except for the start and the end of the line. Thus in any of these puzzles you can have no more than 2 areas with an odd number of gates.

I think I understand the concept, but if there is a solution, it's definately not a conventional solution.

I can prove that this problem has no solution. You can all just give up right now.

Give me 15 minutes or so to write it up.

Edit: To keep you occupied, in a nutshell this is why there is no solution.

It is in fact, NOT impossible. Even though conventional Euler theory and what not would make you think it is, there is a solution.

There was a competition in California for a free car if you could solve it, and one guy poked a hole through his paper and brought his pencil around somehow to complete the gate.

It was a creative idea, but there really is a 'conventional' solution.

As stated, your problem has no solution. Unless you're trying to tell me I can solve it by poking a hole in my monitor. :Q

No, but you went through the top right gate twice. 😛

Edit: Whoops I quoted myself.

I will say that your technique of circling off the middle gates right away was hinted at being a good one.

Damn, lol. The reason I was doing the spiral is because you have to start in the middle because that's the only way to get the shapes with 5 segments.

No. I said that there was once a guy who came up with a creative way at solving it, but it isn't THE way to solve it. There really is a way to do it without cheating, or poking a hole through your monitor.
