Practice more problem-solving at. As Numberland s best detective, you thought you d seen it all. But the desiccated corpses of prominent natural numbers have been showing up all over the city. A lockdown is ordered from sundown to sunrise, and it s still not enough to stop what can only be described as a vampiric feeding frenzy. Can you figure out why the citizens of Numberland are being attacked? Henri Picciotto shows how. MisterVercetti: What I'm confused about is why 461 had slime between 4 and 6. Take that out, and you get 46 and 1, which still leads to all three digits getting drained. I'd figured out the primes don't get drained part, and slime allows non-prime digits to be isolated in otherwise prime numbers bit, but the extra slime between 4 and 6 was leading me to believe the slime had some other purpose as well.

Pretty interesting riddle. What I did not like is that there is no real answer to question 3 (Why the slime-lines were placed that way.
It was pretty obvious that the attacker wanted to drain as many digits as possible. But I did not find a reason for 461 being split 4 6 1 instead of just 46 1.
It took me some time to give up without having a solution and continue watching the video. And I was very disappointed that the question does not have an answer.

1: 36 But why did it split the 4 and 6 in 461? Why didn't it just split it as 46 and 1 since it can then eat both parts? I considered maybe it's working one digit at a time from left to right but that doesn't work either because then 137 could/would have slime between the 3 and 7, and 2099 would be 2, but then have a 0, in addition, 14 would be 1 and 4. I suspect this is just an oversight.

All three are lying: Watson and Hudson either have to both be telling the truth or both lying since they re saying the exact same thing. If they re both honest, then only one of the three can be lying, leading to a paradox. Thus, both are lying, and because we can t have exactly two people lie (otherwise, they d be telling the truth, Sherlock must also be lying.
