The puzzle presented is a classic brain teaser that challenges solvers to find the most efficient way to connect four towns with roads. The answer lies in creating a network of roads that minimizes the total length of travel between all possible pairs of towns.
At first glance, it might seem like building a circular road system around each town would be the best solution, but this approach is actually inefficient and uses too much unnecessary asphalt. Similarly, the U-route and O-loop are also not optimal choices for connecting all four towns with the shortest total length of road.
The correct answer, on the other hand, forms a square with its diagonals running through the center of each town. This unique configuration allows for the most direct connections between all possible pairs of towns while minimizing the overall length of travel. The beauty of this solution lies in its simplicity and elegance, making it an attractive option for those who enjoy solving puzzles.
Interestingly, the solution to this puzzle can be observed in nature, particularly in the way that soap bubbles interact with their environment. When a plastic model of the puzzle is submerged in soapy water, bubbles form around each dowel, revealing the correct configuration. This process mimics how nature finds the most efficient solutions to complex problems.
The author of the article shares their own experience visiting MathsWorld London, a math discovery centre that features an interactive exhibit on soap bubble machines. The centre offers dozens of hands-on puzzles and exhibits, including an elliptical pool table, Morse code machine, and other mathematical play areas.
For those who enjoy puzzles or are simply looking for a fun challenge, the author invites readers to try solving this puzzle on their own. With years of experience setting puzzles, they are always eager to receive suggestions from enthusiasts.

anyway i think the square config is genius why overcomplicate things with all these unnecessary roads when simplicity is the key?
just thinking about it gives me ideas for typography and visual hierarchy... that square configuration tho is SO clean and simple yet effective 
and have you ever noticed how math problems can be so inspired by nature? like, soap bubbles are literally the most efficient way to cover surfaces 
I'm totally gonna visit MathsWorld London next time I'm in london 
! I visited MathsWorld London last year and they have these awesome machines that make bubbles do all sorts of math-y stuff. anyway, if u wanna try solving this puzzle on ur own i say go for it! it's so much fun and u never know when u'll come up with a genius solution like me 
with diagonals on the dot! 
The U-route and O-loop just can't compete with that efficiency. And yeah, it's totally solvable in real life, kinda like how bubbles form around soap... pretty cool! 
I've been to MathsWorld London too 
and it's a total brain-twister paradise 
. Anyone up for a challenge? 
It's amazing how something so simple can be so elegant. I wish I had seen that soap bubble exhibit at MathsWorld London, that sounds like a blast 
. Maybe it's time to dust off my old puzzle books and try solving this one again... or maybe I'll just leave it for the kids 
.
i made a chart 2 show how much less asphalt u need with this config 
total road length saved is like, 25% more asphalt! 
. And isn't it cool how nature finds the most efficient solutions too? Like, soap bubbles solving puzzles? Mind blown! 
If you're into puzzles like me, definitely check out MathsWorld London - sounds like so much fun for all ages 
? i never would've thought to look for patterns in nature to solve puzzles... that's some next level thinking right there 
thats kinda what's happening here, but instead of pretty patterns, its about finding the most efficient way to connect towns 
. i'm def gonna try solving this puzzle myself, maybe with some soapy water involved 
. btw, math discovery centre sounds like an amazing place to explore - has anyone been there? 
The article reminds us that sometimes it's the simple things in life that bring us joy - whether it's a fun road network or a game of tic-tac-toe.
. I mean, come on, a square is way more logical here! It's like how you solve a Rubik's cube - you gotta think outside the box (or in this case, the circle). And can we talk about how cool it is that soap bubbles are basically nature's puzzle solvers? 
but yeah trying to solve it sounds super fun u should def give it a shot if ur bored or need some brain food 
and it was so cool!
