Excellent video! Explaning why evens-odds works has always been one of the hardest bits about teaching the game to new players for me, but this put it in a very logical way
This reminds me of a competition on the Open Redstone Engineers Minecraft server... a few years ago we had a competition to see who could build the best connect 4 AI. They played in a tournament. Was super fun and people came up with all sorts of algorithms.
@godowskygodowsky1155 yes, but can you make a circuit in redstone that actually makes those moves? We had a time limit to make moves. So wasn't able to really do anything that crazy. Almost everyone came up with a unique idea based off some random old tech. Was amazing to watch.. Except my build. Did great!... but I made it a connect 3 by accident, so it thought it won and gave up... I lost xD
@@LordDecapo Oh, you were supposed to do it in redstone. I thought it was a coding competition. Were you allowed external tools? If so, perhaps you could use a logic synthesis tool or some other specialized compiler to convert code to circuits. It'd be nontrivial, though.
@godowskygodowsky1155 there has been several attempts at getting that kinda synthesis working. Only 1 attempts got good enough to match human redstone [that I know of] and it was abandoned.. Also only worked on small sections. The hardest part is optimizing for the mechanics of minecraft, like using comparators and signal strength. [What mine was based on]
This video is one of my favorite things - the application mathematical invariants to logic puzzles. It's such a powerful tool, and you explained it so clearly!
Brilliant video! Connect four is such a nice way to see clear application of math in board games. I never knew that either color would prefer odd or even threats, let alone that odd threats carry slightly more weight. Very logical when said though! I'm looking forward to learn more! :D
In the past few months ive been diving into the theory and concepts behind concept 4 by myself using an online solver. I've individually discovered parity (and gave it that same name when telling others about it). To me it's a relief to see there's more information about this out there than just me at my computer. Great video and I'd love to see more of this!
Very high quality video! Halfway through I scrolled down to subscribe and was shocked that it didn't have hundreds of thousands of views. I would also like to compliment you on your thumbnail + title choice as I don't see people do that very often.
I only use UA-cam for research on astrophysics and Warhammer 40,000... Yet this video appeared on my recommend, and you now have a lifelong subscriber.
Toughourly satisfied and entertained. Excited for the next one :) I will now crush all of my childhood bullies who used to torment me by beating me in Connect 4 repeatedly.
I love that Connect 4 has theory behind just like chess! I'm so excited to see more of your videos on this game. Correct me if I'm wrong, but doesn't the control of the Zugzwang come down to the parity of the rows of the threats? If the threats are either both on even rows or both on odd rows, then yellow will win, but if one threat is on an even row and the other is on an odd row, then red will win.
For the most part, yes. But it can get complicated. For example, a threat on row 2 and row 5 by the same player exerts twice as much control over the Zugzwang as a threat on 3 and 6. We'll dig into things like that when we generalize this theory next time :)
Me and my friends play tic tac toe almost everyday no strategy then slowly over time we invented strats eg double win where there are 2 ways to win so its inevitable and a hole situation where you have to go somewhere bc there is no space left to go I didn't know that these had actual names I invented a strat called towering where u make towers mindlessly for the first 5-10 moves this often ends with complicated games and interweaving double wins and a square can be extremely powerful if exposed to empty spaces as it can make threes effortlessly and can easily create double wins if the opponent isnt careful and many more methods I love this video bc it gives an actually good name for what we call a hole situation (parity) thanks
3:23 counterpoint: it's connect _four_ not connect _five_ . yellow's win is invalid. :p (this is a very interesting video! glad it crossed my feed, it's well put together and your explanations are easily understandable. definitely subscribing!)
Very good video! Where can I learn some basics aside from your other two videos? Also, what's sites do you play on and what site do you use in your videos?
I just watched all your Connect 4 videos. Very interesting. I'd love to see one on openings. One piece of feedback. In the first example of the Candle Sticks Opening, you use the 0 to indicate the place that red needs to NOT play to win. In the next example, you use the 0 to show where red SHOULD block, to not lose the game. This inconsistency in the symbols used lead me to need to rewatch the examples a few times to understand. This should be an easy fix if it's something you focus on moving forward Looking forward to the next video!
Yeah, perhaps I should have notated that a bit more explicitly. 0 means tie, + means win, - means loss. So in that case, red could have won by not playing the 0 at first, but then after committing to the tying line the best thing to do is tie instead of lose.
@@twoswap ahhhhh that does make sense. Yea maybe right at the start before you start going through examples you could do a short key for people such as myself who are newer.
“You can always deterministically know the result of the game once you reach the endgame.” Ah, but consider, I’m stupid and miss obvious threats in Connect 4
Hey mate. Like naughts and crosses, connect 4 is a solved game. Once you learn perfect strategy, you cannot lose as the first player. A good player will not provide easy opportunities to win before the final column.
@@FRAXMET As someone with hundreds of hours in the game, 2swap is absolutely right. Maybe not "longer than a lifetime," but many years of committed practice and study, for sure.
I figured this out on my own after playing connect 4 like 15 times a day on game pigeon with my friends, now none of them nor my family can beat me… they better not find this video
Good... no. There's papergames and boardgames.io, but they are both pretty buggy with bad UI.

The views plummeted when I did lol I always thought youtubers were exaggerating when they said the algorithm works in mysterious ways. These past few days have been a bit of a culture shock haha
@@twoswap That is such a shame, but i get that people don't like hopping on the "middle" of a thing, so it makes sense that if they see a video that its like part 3 of a series that they would not open it :(
It's crazy that I paused to think "wait, doesn't that mean red wins in games where they have row 1/3/5 threats and yellow wins with row 2/4/6 threats" right before you went and said it
There are ranked servers online. None of them use ELO, although I don't see a technical reason why you couldn't. You would probably want to modify it slightly to account for player 1 advantage, but it's definitely possible.
@@twoswap How would an anti-cheat for connect 4 work? I feel like it would be MUCH more difficult to detect engine moves in connect four compared to chess
In an automated fashion, yeah that would be very hard. Human experts can typically spot a cheater though. During the game, way more entropy is contributed by player 2 than player 1 since p1 is much more often forced, so usually the giveaway is in games where the cheater plays as p2. Engines usually don't know how to play in a creative and confusing fashion to throw player 1 off, but instead just try to lose as late as possible. However these lines are few in number and usually pretty simple to defend against. So the typical cheater will play perfectly against complex openings as player 1, but play naive openings as player 2, and still lose (always on row 5.)
Yes, but that's not strictly a result of parity mechanics. As an example, boards with a height of 6 and width of 9 favor yellow, even though the parity of the height and width match the standard board.

@@notthat1901 The person who told me that was my college English professor. Also literally any dictionary. Yes, "they" is becoming more accepted as a generalized pronoun when the gender is unknown, but "he" is more widely-accepted and has been for centuries.

@@notthat1901 Well regardless of what you think, the generic "he" has been used as a general pronoun for a very long time and is still accepted by grammaticians.

On top of that, the animations are very well done - informative and very pleasing to look at. Much higher quality visuals than I’d ever expect to see in a university course. Subscribed, can’t wait for the next one.
Ok so I’ve never even thought about learning connect 4 from yt but I used to play with my dad as a kid and I’m pretty good bc most of my friends can’t beat me even once and it’s like the only skill I’ve ever had in anything and I love the game so much
I didn't realize people had a community for this game, I would have expected that since the game is solved (player1 has forced win using perfect play) that it would never have any videos like this, not too into the game but interesting to see.
It's a difficult enough game to play perfectly that only a few people have achieved that or even come close. It takes a lot of practice and study of concepts like this
Ive been waiting for a video like this for a long time. This is really the best connect four strategy video out there. Before this video, the only way to find this information was by reading the james dow Allen's book or by searching the corners of discord for nerds.
The algorithm brought me here, and I know very little of the game’s strategy beyond what’s directly in the video, but I think I see a trick here. Say Yellow has two threats in two different columns (both empty for clarity’s sake), one on row 3 and one on row 5. Neither are good parity for yellow. But still, red is essentially out of luck. There’s four spots of free space, and since all’s left is two columns, it’s red’s go. After four turns, red will have no choice but to tread on the Danger Spaces, leading to yellow winning. Having an even amount of free space below/before two of your threats at the start of your opponents turn seems to be a key for setting up… whatever that Z word is you mentioned, I already forgot it. Maybe this is explained in previous videos, I dunno.
It would be great if you sourced your work. Whether you used Keith Galli's Odd Even Strategy video or whether you followed Victor Allis's solution to connect 4, papers, etc.
I only intend to cover stuff thats common knowledge as well as my own original discoveries. Those who want to read victor allis can do just that :3 Although I will talk about claimeven. I'll be sure to mention the paper in which the term was coined.
Hi, please consider using different colors (or patterns on the pieces) for contrast. Red and greenish yellow are difficult colors to differentiate for many colorblind viewers. Thanks
Going to try with #DC267F and #FFB000 next time, and I'll add a ring around the piece with slightly different color to hopefully provide more signal. thanks for the tip
@@twoswap Really appreciate the reply! Those colors are definitely more clear imo. Good idea with the ring as well - even something subtle like a darker value of the same color would probably work just fine as a differentiator. Looking forward to your next video :)
This is an amazing video and got me into connect 4, can't wait for the rest of the series. Will you be showcasing openings or stick to the game theory?
nice video, editing makes it enjoyable to watch. also i can’t tell whether the circles are slightly oblong in varying direction or if it’s a visual illusion, but it makes for a cool aesthetic

Maybe this is explained in previous videos, I dunno.
Spot on! This is covered in the next video.
It would be great if you sourced your work. Whether you used Keith Galli's Odd Even Strategy video or whether you followed Victor Allis's solution to connect 4, papers, etc.
I only intend to cover stuff thats common knowledge as well as my own original discoveries. Those who want to read victor allis can do just that :3
Although I will talk about claimeven. I'll be sure to mention the paper in which the term was coined.
Hi, please consider using different colors (or patterns on the pieces) for contrast. Red and greenish yellow are difficult colors to differentiate for many colorblind viewers. Thanks
Going to try with #DC267F and #FFB000 next time, and I'll add a ring around the piece with slightly different color to hopefully provide more signal. thanks for the tip
@@twoswap Really appreciate the reply! Those colors are definitely more clear imo. Good idea with the ring as well - even something subtle like a darker value of the same color would probably work just fine as a differentiator. Looking forward to your next video :)
This is an amazing video and got me into connect 4, can't wait for the rest of the series. Will you be showcasing openings or stick to the game theory?
I will touch on everything :)
nice video, editing makes it enjoyable to watch. also i can’t tell whether the circles are slightly oblong in varying direction or if it’s a visual illusion, but it makes for a cool aesthetic
Hm, they should be circular circles!
U make me scared with those words lol
it seems like a yellow odd threat can neutralize a red odd threat, is this correct?
For the most part. The entire next video is dedicated to the subtleties of this property.
@@twoswap awesome! looking forward to it!
This feels like a SoME video, you should consider it if its not!
