There are 2 missing squares in Funny Bunny
Audience:
Tags: combinatoricsgroup-theorygraphsfunny-bunny
We explore group theory through the childhood board game Funny Bunny and discover how it relates to the pattern of the holes that appear during the game. This allows us to understand why exactly two squares are missing (and create some pretty visuals along the way).
We then dive deeper into beautiful graph-theoretic ideas and a surprisingly advanced formula at the end, using only simple visualizations and intuitive reasoning.
Be warned, this video has a “slight” French accent, and I truly hope it is still fully understandable. Also, this is not the original video (which you can find on the same YouTube channel). I created this unlisted English-dubbed version so you wouldn’t have to rely on either the original French audio + english subtitles or YouTube’s AI-generated dubbing (YouTube does not yet allow me to add an additional manual audio track to my videos…), but if you feel like it, the original is definitely much better!

You went too fast through the rules of Funny Bunny for me. I would have liked to see a full game play out. In particular, I did not understand what the carrot is doing in the game.
It’s a really nice video with great graphics, but i found it a little shallow, it could’ve been really interesting to dive more into group action and group properties, (maybe showing a non abelian version of the game? or proving the formula at the end?) at the end of the day it’s really good for an high-school level first look into group theory, but for an undergrad level i find it lacking
To me, the video was really three parts: First, a very cool introduction to group theory using a simple board game. Then, a section where the game gets improved, but for me that wasn’t very well motivated. Finally, a short section that shows some nice graphs, together with a short mention of math that is several orders of magnitude more advanced than the beginning.
It’s a bit risky to go from a definition of what a group is to a lot more complex topics, but using a game and nice visuals make the process at least somewhat fun and entertaining.
The video may lose a lot of the audience along the way, but I think the few people who will stay on to the end might be worth making this video! I think it would have helped to define the motivation for changing the game more clearly and/or to shorten the middle part.
Great animation, great music, great topic. I loved the montage of the various stars of paths near the end of the video. Nice introduction to group theory, good to leave the equation at the end for more technical viewers. Overall, a wonderful video.
The drawings were engaging. The delivery was clear. I usually don’t think about the underlying geometry or mathematical theory behind board games so this was an eye opener. Of course a set of dice would really make things interesting. By the way, the production values on this video were top notch.
This was a rather good explanation of group theory! I enjoyed the visuals and analogies throughout the video! However, this video has a few issues that brings it down from being a perfect video (not including the French accent even though that did severely hinder the viewing experience). For one, the video doesn’t really explain the actual math itself; now it does explain some things in the first half of the video (like cyclic groups), but in the second it just kinda derails into visuals and barebones explanations that don’t really explain how it connects to the final math expression at the end of the video besides for highlighting things and saying “Go off of this, have fun!” though I do understand it would be difficult to explain everything there within 15 minutes. Besides that though, the video is pretty well made, and definitely stands out from the black-ish background copy and paste in which I’ve seen everywhere! Good job, and I wish you luck on your content creation journey!
I think the mechanics of the game should be explained more clearly. For people who don’t know the game, it’s very easy to get confused.
This was overall a great and highly polished video. It has good graphics, a good script, some jokes which landed, and the standard of the spoken English was certainly no problem. The math was overall well explained, and it was really neat how advanced concepts were linked to a simple board game.
Since I must critique it as a peer reviewer, I would say that the only things stopping me from giving it the maximum score are that some of the explanations were a bit rushed, and that topic is a little trivial. To the latter point, it seems a little incongruous that such complicated math is discussed in the context of such a simple game, and may overwhelm some viewers, though this is minor.
I personally missed the justification for how the final version of the game was physically possible, since the holes on the rotating board underneath the main board, which you described, must be sufficiently spaced for the game to work. I also don’t think it was explicitly stated what happens if a rabbit lands on a hole in the game.
Overall, though, the video was fantastic!
Nice animation style and good presentation.
I think we can explain the rules of the game a bit more as we don’t have a good visualization of how it’s playing and how that leads into the problem. Overall, I find that even though group theory was introduced, in terms of actually using it, there wasn’t that much that used the results of group theory to understand the problem more (I didn’t quite understand why we needed to introduce this terminology), when we could just use the individual group elements to understand the problem.
It also wasn’t that clear in terms of where the video was going with the trying to establish the link between combinatorics and group theory near the end. I think it has quite a bit of potential. It needs a bit more work to build up to it.
- Motivation: I’d never heard of Funny Bunny before but you made me incredibly invested in this
- Clarity: The bit with the needles was a little confusing, I had to rewatch a couple of times to fully understand it. Otherwise very well explained
- Novelty: Definitely a new (unexpected as well!) way of delivering this topic
- Memorability: The diagrams were in fact quite pretty, and the style of the video was very well-executed. I loved the visuals and think they were immensely helpful with the explanations
misc:
- the Minecraft music near the end caught me off guard there. It is copyrighted though; you might want to look into that
- the accent was completely understandable to me (I do know a little bit of French though, so I might have just been used to it)
FWIW your French accent is completely fine, don’t worry about it :)
This video was very good :-}
One pitfall is that I did not have the funny bunny pre-requisite material under my belt, so I had a lot of initial questions about how the holes were being created & how many holes there were etc. I was also confused why you said holes were “missing” haha.
I could have used more of an explanation why the groups were actually connected to Funny Bunny, seeing as this is a Funny Bunny focused video, but I thought the explanation of the groups themselves was very good! (Also, a little surprised you didn’t mention abelian groups … R3 + R4 should give us the same thing as R4 + R3, but that might not be relevant to the FB problem) The equation at the end was super forced; I don’t really think you need to put that in there to make it feel relevant, the graphs speak for themselves
The graphics were really nice & very helpful for the explanation ^_^b
Update: I’ve watched this video 3 times now, and I want to give really detailed feedback because although there are some things I have issues with, there’s something really intriguing about it to me. I am a very curious person myself, and this video explored something in the way that curious humans do (starting in one place and ending in a completely different one) which I thought was very beautiful. My neurodivergent ass loves writing very long things, so here’s a script review of the video I did because I liked it so much <3 https://docs.google.com/document/d/1kin1j6aLDwLhMHMfYZk_tZmDf003HPa_-Alv0rCwWQA/edit?usp=sharing
I put a surplus for the obvious english effort! Otherwise the video is really interesting, despite the not-so-attractive topic in the first place. I followed every step with curiosity and enjoyment because every time something came to my mind then it popped up in the explanation. Visuals and pace are definitely just right. Music doesn’t really add anything but is less annoying than other videos. Keep up the good work!
This video began with very little motivation, and because I am completely unfamiliar with the game funny bunny, I was initially quite confused and disoriented. As the video progressed, I became slightly more oriented, however, I was still confused as to the motivation. Approximately halfway through the video, the creator suggested that we now understood everything and we are happy. But again, I am perplexed as to what the point is. Yes, we learned that there is a group. But so what? What does this group have to do with anything.
As the video progressed further, I unfortunately became more and more confused. Apparently I must have missed something because I am now completely lost.
From a big-picture perspective, I thought the creator did a nice job with the graphics. The animations were generally helpful for making the video engaging and more understandable (not considering the fact that I must have missed something important). But overall, I didn’t find the video al that useful. I just didn’t understand the point of the video and I didn’t understand the final “result.” For this reason, I gave the video a rating that was not very good.
Amusing and engaging. I really liked the idea. Light atmosphere, engaging narration, and beautiful graphic.
My only gripe is that the author does not formally specify the problem they are solving. And I think it’s because the overall result is a bit weak. It’s less of an exposition of a really important concept, and more of a tour of a nice exercise. Which is fine! But I think this fact could have been mitigated better.
But overall, a treat.
It is always fascinating to discover the mathematics hidden behind a simple game, and connecting this game to group theory is an interesting idea. The video offers a perspective on something that initially seems purely recreational, which makes the mathematical connection memorable.
The most engaging part for me was the redesign of the game. Showing how the game could have been designed differently makes the mathematics feel more meaningful and gives the explanation a clear purpose. I also particularly liked the beautiful illustrations, graphics, and animations. They make the exposition visually appealing and help maintain interest throughout the video.
One aspect that could be improved is the motivation for introducing group theory. The explanation does clarify why the game has a missing square, but it was not entirely clear why this mathematical fact matters. Knowing the reason behind the missing square is interesting, but it does not seem to help us play the game better, develop a strategy, or gain another useful insight. I would suggest making this connection more explicit - for example, by showing how the group-theoretic perspective leads to a strategy, a prediction, or some other consequence that the viewer can actually use.
Overall, the combination of a mathematical connection, a creative game redesign, and strong visual presentation makes the video engaging and distinctive. The redesign in particular is something I would remember after watching the video.
