SU puzzle

The aim of the game is to connect all 3 houses to water, electricity and gas suppliers without crossing any lines.


Some guy gave it to me, saying that him and many others tried to solve it but couldn't. I've been trying to solve it for the last 15min but so far no luck. It's like impossible...

Let's see who's smart enough

it is impossible, the mathimaticans here in germany call that a K_3,3 graph (there is also a K_5 graph), it is impossible to draw a plain graph (no connections are crossing) if you find something like that in a graph. I could try to prove it, there are some mathematic theromes about that, but I'm too lazy, just believe it, it IS impossible:D
Well, it would be possible if you draw the houses and the water/fire/lightning on a ball, but not on a 2D paper xD
Now I know why I studied this shit for 1 year

Yes I think it's impossible, there's also an explanation of it in the Graph Theory I think.

This can't be done on a flat surface. So don't spend all your time trying

There's a math way of solving it using some of Euler's formulas. I can't remember how and I'm too lazy to think about it.

I could have sworn I did something like this in fourth or fifth grade in tag called the kindergarten test or something like that (because adults struggled with it and kindergartens usually got it in less than a minute due to adults mental block that a line has to be straight) but there were only two blocks... three is impossible. I tried to swirl it around a bunch of time but the last 2 connections never work.

http://en.wikipedia.org/wiki/Complete_bipartite_graph

A planar graph cannot contain K3,3 as a minor.


what that is saying is that you cannot construct a graph that has three vertices, each of which are connected to each of another three (different) vertices.

Yea i manage to connect them all but one.

Well, since it's on that site i thought it has a solving. I tried all sorts of lines but it always remains one last line impossible to be drawn .

Haha, lol Klive5ive.

I like that solving Cyu, impressive haha.

On a serious note, i've solved it:

Oh well, it's a glitch or something, you must draw the line through a house. You stop just before you connect the house then right click and move mouse at the other part of the house then left click ... and line is continuous through the house. Disappointed that this has no real solving but was fun spending 40min thinking about it.

Nice, so in fact someone who simply says there isn't a solution is just not thinking outside of the box .
No I'm never serious.

yeah, there's plenty of ways to solve it if you break the rules. I prefer the 3d solutions myself, you can make pretty weaves of uncrossed lines that way.

It's a graph maths well known problem. What I wonder is why they added the You Win animation when it was imposible to solve it =/ xD
I've been around since it all started, and it feels good
