There are two sisters:
one gives birth to the other
she, in turn, gives birth to the first.
Who are the they?

This one broke our brains for a long time. GET READY

A group of people with assorted eye colors live on an island. They are all perfect logicians -- if a conclusion can be logically deduced, they will do it instantly. No one knows the color of their eyes. Every night at midnight, a ferry stops at the island. Any islanders who have figured out the color of their own eyes then leave the island, and the rest stay. Everyone can see everyone else at all times and keeps a count of the number of people they see with each eye color (excluding themselves), but they cannot otherwise communicate. Everyone on the island knows all the rules in this paragraph.

On this island there are 100 blue-eyed people, 100 brown-eyed people, and the Guru (she happens to have green eyes). So any given blue-eyed person can see 100 people with brown eyes and 99 people with blue eyes (and one with green), but that does not tell him his own eye color; as far as he knows the totals could be 101 brown and 99 blue. Or 100 brown, 99 blue, and he could have red eyes.

The Guru is allowed to speak once (let's say at noon), on one day in all their endless years on the island. Standing before the islanders, she says the following:

"I can see someone who has blue eyes."

Who leaves the island, and on what night?


There are no mirrors or reflecting surfaces, nothing dumb. It is not a trick question, and the answer is logical. It doesn't depend on tricky wording or anyone lying or guessing, and it doesn't involve people doing something silly like creating a sign language or doing genetics. The Guru is not making eye contact with anyone in particular; she's simply saying "I count at least one blue-eyed person on this island who isn't me."

And lastly, the answer is not "no one leaves."

My friends and I had to really talk it through and took many stabs at it before we finally sort of figured it out mostly...

Then we looked it up lol. It's a crazy good riddle and i encourage everyone to try to brain it out!

ugh I had to look that up. I suspected it was something like that. Though I did wonder if they islanders were able to show each other their counts. If they could compare, they could start to deductively reason it out. I mean if I have 1 green, 100 brown, and 99 blue on my count, and I know my partner has blue eyes.... and my partner has a count of 1 green, 100 brown, and 99 blue, than deductively, I could determine that we are counting the same green and brown eyed people because partner has blue eyes. If they had brown, their count would be 1 green 99 brown, 99 blue. but its not. Thus I could determine that I have blue eyes ..... I think?

Interesting concept! The only thing is it explicitly states that the islanders have no way of communicating with eachother :P

Five hundred begins it, five hundred ends it, Five in the middle is seen; First of all figures, the first of all letters, Take up their stations between. Join all together, and then you will bring Before you the name of an eminent king. Who am I?

Honestly I didn't know it either until I saw the answer.

But I also feel like this is relevant too:
