I like the idea of the a puzzle. If you had a mathematical concept in mind, then it would be awesome to mention how it ties in with the puzzle. It's like a puchline. Also, the end is too quiet. Some slow music in low volume would help a lot.

Good fun! Interestingly, when you suggested extending beyond the square table, my first thought was a cube. I'm glad you mentioned that at the end (albeit briefly), but the best part is, a cube is (I believe) entirely equivalent to an octagon.

A nice puzzle that had good extensions in terms of generalizing the problem to a higher dimension and good explanation. I also liked that you encouraged people to think about the solution of the problem as well. One way to improve would be to make this tool as a small game people could play with so that it'd allow us to interact more easily with finding the solution and getting that moment of figuring out a solution.

I have a double feeling about this entry. The problem and the result was really interesting, but it was hard to follow the arguments in several points. Maybe it's just the nature of the problem, because I don't have an idea how to make it better. Thanks for sharing

Nice, the solution is expressed beautifully with a generalization. Highly engaging.

You lost me at the proof that odd number tables don't work. The proof for even numbers not powers of 2 seems wrong, you confused an implication with its converse. An odd solution would give a solution to the even solution, but there being no odd solution just means you can't use that approach to get the even solution, not that there is no even solution. The topic is really interesting as well as the approach and explanation in the first half. I think there could be more motivation, meta-commentary, background, or elaboration of learnings. I thought the explanation for the first half was just right for me to understand, but I don't know if someone else would have more trouble following. Should have explained that the solution must be deterministic or not depend on luck in the beginning instead of after we dove into the solution. Optional, for math purists this is just fine but for many youtube viewers more jokes or grounding in real life might help people's retention? Awesome animation, I envy your skills.

Good, intriguing problem.

A long video for a relatively uninteresting problem already seen somewhere else. The quality is good and there was effort to create it, but it's a bit boring

The video was well edited, I like the problem (it was novelty and interesting), but you give the answer to fast. It would be interesting if you take more time to show why the problem is seemingly impossible and why it is not obvious to find an strategy. Also the storytelling around the devil mathematician was cool, I hope you can also create a prisoner character to enrich the story.
