  1. This sounds like it might be a homework problem, so I won’t flat out answer it but will give a hint on how to approach it.
  2. Right on, that solves the square problem with the minimum number of breadcrumbs.
  3. Good start, that would work, but the square can be done with fewer breadcrumbs.
  4. That's definitely not a silly question. In the question I had in mind, the paths don't need to be straight lines. But down the line when we solve the pentagon case and start thinking about generalizations, we could talk about solving for cases with straight line paths.
  5. You could be telling the truth because such a number does exist. Of course I can't say with certainty that you're telling the truth because I don't know whether you actually have such a number in mind right now. Back in a bit with a description of how to handle this problem.
  6. In case this helps clarity: the warm up problem is to take this setup with the mouse at A (I told you it was cute!) and breadcrumbs at B, C, D, and your job is to place more breadcrumbs to ensure the mouse goes first to C, then B, then D. Ideally, using as few breadcrumbs as possible. The real problem is to take this setup with breadcrumbs at points B, C, D, E and place more breadcrumbs to make the mouse go first to C, then E, then B, then D. Again, using as few breadcrumbs as possible.
  7. Warning: This is a problem I have not yet found an optimal (or even very good) solution to. But it seems awfully non-trivial, and not in a genre that I've seen before, so I'm throwing it out there for the Den. ( @bonanova that means you should take a look.) You have a pet mouse. It's an awfully cute mouse. Kind of like those mice on Pinky and the Brain. And you'd like to make it even cuter by teaching it some tricks. The only problem is that your mouse is, well... let's just say it has the brain of a mouse so it's kind of hard to teach it any tricks. But it is very good at eating food. In
  8. If anyone tries asking people this question in real life, a follow up after they've heard that answer: If a ship with tourists from Europe sinks on the way from Alaska to Australia while in contested Chinese waters, where would the deceased passengers be buried?
  9. Push your feet upon on my pedals While the rubber meets the road Then as urge for fun unsettles Lose my grip, so off we go My engine wrapped around a tree Your limbs are but a price to pay All for this pursuit of glee On single foot now make your way
  10. Well, I've shown a lot of ways where Arcsin could win, but I don't actually prove that Arctan can win in cases that aren't covered in the above ramblings. An ideal solution would be along the lines of: "If the composition of the Praesidium meets these criteria then Arcsin has a strategy that's guaranteed to win, and if it doesn't fit those criteria then Arctan has a strategy that's guaranteed to win."
  11. Have been thinking about this for a little bit, and now ready to take a stab
  12. Right on! I wrote this riddle just after seeing essentially this
  13. I had to think about it a bit to convince myself that the statement at the end of the first paragraph is really true, but I believe it is. For anyone not seeing it easily:
  14. You're getting quite close, plainglazed.
  15. Getting warm, but still looking for something that's hidden while out in the open.
  16. I'm not a picture frame. Tough in my mind to interpret it as having been found only by those now dead. Also not a skydiver. I'm something more commonly known for grabbing everything. Not an excavator. I don't envision him hanging and then being hung by the same "man". And also not a shovel for similar reasoning.
  17. I watched the video, and overall liked it. Since you asked for feedback: with the video format, I think I would prefer to see the question and be told to pause to have time to think of the answer before it appears instead of having a set amount of time for each question, since with at least some of them you either know it or you don't right off the bat. As it is, I got a little annoyed waiting a minute for the answer if I already knew it. The other main comment is something DejMar sort of alluded to, that there are potentially multiple answers that would make sense for some of the riddles
  18. Not an escalator. If I remember correctly the track record here has been that people's guesses about the difficulty of their own riddles ended up having little to no correlation with how tough they were for everyone else, so who knows.
