Yeah but what blows my mind is how do they even come up with these scenarios anyway???????
No, I can’t solve it. Thank you for believing in me though

my exact thoughts: i sure can’t solve it, but i’ll enjoy the video i bet

Same bro

This reminds me of the chess concept of "opposition". You can use this concept to turn seemingly drawn king and pawn endgames into win. The chess equivalent of the strategy used in this puzzle is known as "triangulation" where you go in a triangle pattern to lose a tempo. I would encourage anyone interested in graph theory to look into chess "opposition".
That's how I was able to notice the "color" issue and solve the riddle, especially since I've seen chess puzzles revolving around the fact that knights can't triangulate or where a long calculation is simplified by the fact that the pieces in question have to change color every turn.
Step one is to figure out the need to triangulate via the end hub. Step two is like something between a Queen vs. King checkmate and using your King to force the opponent's King around in various endgames, both of which are part of basic endgame theory. And like in many chess endgames, you can only win by repeatedly putting your opponent in zugzwang.
In fact, one common mistake beginners make when trying to checkmate in a winning endgame is to constantly check the opponent's King when it's often more productive to make non-checking moves that narrow the King's options and leave him with no choice but to move in the general direction you want, just like in this riddle.
Same!
Once triangulation comes to mind it is relatively easy to solve it, since the right edge has triangles in it.
I am just interested in getting better at chess so thanks
This also works with king and rook endgames
The fact that our super intelligent, problem-solving spider is called Charlotte is such a nice touch
Charlotte's Web.
is it from that piratte riddle?
@@debadityanath4398no it’s based off a popular children’s novel Charlotte’s Web.
Imagine training for years to become the great spider champion only to see that a baby spider beat you to the throne
baby spider is the main character
@@yusrarehan7950 no duh.
In the queen's defense though, the game was quite literally rigged so that she would literally have no way to counter the baby if it played optimally.
the queen was about to die, they need a new queen, everything that happend to the baby spider was just a test of passion (she truly wants to rule), power (most of the spiders support her), obligation (by the end she placed a web around the city conquering mankind), and prospect (the queen's final test that proves that she thinks of the future as well).
Then again it wasn´t just ANY baby spider! It was Charlotte from Charlotte´s Web - the most amazing of all spiders: en.wikipedia.org/wiki/Charlotte%27s_Web
The fact that Ted Ed used so many references in a video all about spider stuff is awesome
Charlotte's Web was a classic. My class read it so many times. It's one of my favourite books😭😭😭
Arachne's tale is also another one of my favourite myths. Props to Ted ed for all these references.
Anansi - Western Africa Mythology
Aranche - Greek Mythology
Shelob - Lord of the rings
I wanted an undertale reference though

Imagine being the spider queen and being subjected to a final game where you can be 100% defeated if your opponent knows what’s going on and not based on skills or anything
She could win if everytime you moved towards the far corner she also moved in that direction and then when you got there she would jump you because she would only be one move away from green. Giving her a 100% chance to win. This wasn't a very good puzzle.
@@edyknight9218 what do you mean "jump you"? Once you reach the green, she cannot reach the column of hubs closest to green because you will land on her spot
@@nhavinedyourking7593 Edy Knight is assuming that the spider queen is allowed to capture you and thus win the game for herself (Which is fair because the rules never state that she will not or can not capture you). So if both you and the spider queen move directly to the green then by the time you land on the green the spider queen will already be on the column of hubs closest to the green and can just capture you while you are on the green.
Basically the rules should clearify wether or not the spider queen is allowed to capture you.
@@1upsoda ahh that makes sense
As per usual in rules, if it doesn't say something, then it's not possible to do so. Nothing says the Queen couldn't hire a Bat to come and scoop up the contender and eat it, but I'm pretty sure it's not permitted.

I KNEW IT! I literally went through "trap the mouse" style (you place boxes to trap a mouse, old flash game) and noticed you basically couldn't corner her, then i saw the tiny thing at the end. If you go up, and follow her as she goes off to the right, she'll be forced to the end bit and will be easy to catch. I didn't think it was that easy.
I actually got it right, I never thought of the coloring method, but I did guess to go towards the end first and trap them in the corner. Love this video!

I didn’t realize that the rest of the string to the converging point was one move :/ I was confused, thinking that it wasn’t showing the entire built out board and that there were more intersections.
The TED-ED logo convenient blocks that point, which makes it hard to see. This was very much a "I failed to solve the puzzle because I didn't know all the rules" kind of puzzle.
Don’t give up maybe next time you will get it!
I was on the right track with that far spot but didn’t even think about back tracking
Any week that starts with a TED-Ed riddle is a good week.

When I was watching it at the start of the puzzle, I realised that they would have to be cornered, as there is no possibility for you being able to move into them. When they said cornering doesn't work, I was confused because that's exactly how I figured out how to win. I was happy for the conformation.
Also, On your 5th move, it is actually possible to win in 8 moves and not 10, depending on where they were. Overall, great puzzle. Simple, but great.
these riddles are just so fun to eventually give up on
I learned to solve this one from Crypt of the Necrodancer. Some enemies in that game move one square every time you move, so attacking them safely requires a similar calculation. If they're an even number squares away and you move next to them, they'll get the first hit on you, but if you make a waiting move (like hitting a wall), that forces them to move to the opposite colored square and you can move up and attack without fear.
Im not even here to solve it , I’m just hear to enjoy ted Ed
It is…acceptable.
It’s totally doable and pretty easy mate just have to try
@@uncanadien3272 NO ITS NOT
same
I never even try to solve it
I thought the same 'Catch the opponent' rule applied to the blue spider too... With that in mind i moved the spider so not to get caught by the blue one on the next move... Simulated the blue's move and I think I did it... using the same node
The fact that the spider made a Klein bottle out of string is just outstanding.
I feel like TED-Ed's riddles have gotten easier recently, which I really appreciate because even though they're still difficult, I'm actually able to solve them now.
Or maybe you've got better at solving new problems
or maybe its both, they arent mutually exclusive
This was nowhere close to being difficult
@@CrazyAvidGamer yeah i agree . It would be quite a phenomenon if ted ed was tricking its viewers into feeling smart by gradually lowering the level of the problems lol
@@Batman_94 I'm not sure.
I think it's a fairly difficult problem which APPEARS a lot easier AFTER you learn the solution, but the solution itself is somewhat elusive.
It's difficult because there is no standard algorithm, or recipe for tackling such problems.
Understanding the strategy, and coming up with a winning strategy AND a proof why the strategy always works are two different things.
if you really think it's an easy problem, then please tell me why the strategy works - but without using the parity argument.
I think you'll realize it's a difficult problem with only one easy solution and a lot of blind alleys.
I loved this! The "Web Design" & the reference to the Olympics "weaved" seamlessly into this riddle. 😉🕸
And references about the book “Charlotte’s Web” by E.B. White.
Also the reference to the World Wibe Web.

@Salah Mohamed watch the video
Unlike most of Ted-Ed’s riddles, this is actually something we can do fairly easily given enough time or just by pure intuition
What about that "Mogwarts" riddle?
yeah i thought that point on the farthest right'd have something to do with the answer
Yea i thought it out in 10 mins or so but I needed to see the first couple seconds of the solution in order to even understand the riddle correctly. I was unsure wheather or not you could catch her on moves before the tenth or if it counted as a catch if she moved on top of you
@@skya6863 Yeah, I was unsure about it at first, but once I realized the even/odd pattern, it was clear that the rules have to be as demonstrated later for the problem to work. Would have been nice if they stated that more clearly up front, though.
Yeah, this one was pretty easy but due to the prestige of being a Ted-Ed riddle, almost all of which are far above my skill level, I'm still pretty damn proud of myself for solving this one

@@normanbates5182 it seems like neither party can skip their turn

Haha! Me too.
This is very similar to the chess concepts of opposition and triangulation. If your opponent has the opposition, you normally cannot get around the enemy king, but if you can triangulate your own king but your opponent cannot, you are able to.
I was about to comment the exact same thing. Those concepts helped me solve the puzzle.
yeah, solved the thing easily because of exactly this. I happen to really like chess.

@@Razuki5 you can pause the video you know
I love how realistic these scenarios are
i really like these logic puzzles, it is alot better than the prisoner riddles that bring up info that wasnt mentioned in the original riddle
I didn't colour code, but I did figure out that moving to the end and moving back changed the pattern of movement.
However I couldn't trap her, I ensured that she was the furthest away possible with the best move and could never get her by the tenth move, always needed more.
I personally find it terrifying that at any point in time a single spider could choose to have all spiders attack whatever they choose
I'm happy trianguling in chess has taught me something. This entire riddle is very similar to a chess endgame puzzle haha
in chess u cant have that green spot so ur point is just bs
yea i was looking for someone else who noticed the similarity with chess !
I felt it was more of an opposition puzzle. The Queen spider started with the opposition, so you had to use the right point to take it away

that was the smoothest Segway ive ever seen dang
I actually thought of something, I haven't seen the answer, but what if the answer is chasing Shelob to the point on the right by moving up one and following to the right turn after turn until she corners herself and you're one space away from grabbing her? After that you just slide over and grab her.
Edit: Ok well I guess the answer was kinda the opposite, but I wasn't wrong about the point being useful.
im glad someone else thought of this too

“Spider Games”
Video was made: August 10
Me: If only you knew what was to come
There was nothing in the rules about REMOVING paths. My solution was to remove vertical strands as I crossed or passed them, making only the right endpoint a viable hub where two strands meet by the 7th move.
There was also nothing in the riddle about using a gun, so I just shot the damn spider so she would stay still
Well, it's a spider web so if you remove any of the web, it will kill it's integrity
"Web design" and "whirled wide web!!" Great puns!!!
When you enter spider olympics and the finals are just a game where the challegnger ALWAYS wins against the champion if he knows the algorithm to solve the puzzle. I am gonna call it a fixed match ladies and gentlemen. Queen Shelob had no chance to win right from the very beginning.
Except she could just eat you. Nothing in the rules about that.
Plot twist: The game was designed with that end in mind. If you want to rule all of spiderdom for a century, you'd better be smart enough to figure out strategy.
@@ratoim Queen Shelob sitting there like: Did she understand the algorithm through the years or not?
When the challenger b lines to that single green point.
Queen Shelob: *Chuckles*, I'm in danger.
Yawwwn...this didn't exactly get the spidey sense tingling.
@@athanasiosp. What if queen shelob goes to the green point first? :troll:
The thought of this alone is terrifying
I had the Same idea, with out using the final point. Getting her into a corner, and "blocking" the only 2 ways out is a tricky maneuver. but with luck you could possibly catch her in less than 6 Moves.
That was great. One of the few I've solved on my own, too! I thought of it like a chess endgame. First, I figured out what would happen if the enemy had the first move. I found that it would be a win for me as long as I moved to be diagonal from her, putting her in Zugzwang. The trouble was "passing the turn." Because I could use the last point to mimic a chess triangulation tactic, I decided to see what would happen if I rushed there. I found that if the enemy raced for it, I would win by moving to the diagonal points, kind of like taking the opposition in chess and putting them in Zugzwang each time. I tested it out with the enemy choosing the stay on the back, and it still worked, so I determined that that was the answer.
Who knew chess would win me the Spider Olympics?

Reminds me of a queen/king checkmate. You have to move your queen a knight’s move (L) away from the opponents king and follow their move directly to stay in that pattern until you can bring your own king over to win.
you don't need to do this. just 5 moves will do. move up the first step and then move parlel to her moves. the 4th move later she'll be on the green dot and you can catch her there

Fun Fact: Shelob is actually an character from The Lord of the Rings.
Yeah I think we all know that (Right?)
Hey, I was pretty much there! I figured out that you could only trap her in a corner, but first you would have to use the common point to get 3 spaces away. But I didn't figure out the easy way to understand it or prove that it would always work.
