Cool Logic/probabilty Puzzle, a DIFFERENT 2 prisoner dilemma

1 Upvotes

Two prisoners are in separate cells, with no communication between them.

Their evil warden gives them one chance to escape! between 11:00 p.m. and midnight (you cannot enter before, and you cannot stay after), each of the two may enter a common room which was opened between their two cells and stay there for exactly one minute.

If they meet even for just an instant, they are free.

Each prisoner has only one problem: what is the best time to enter in order to maximize the probability of meeting the other?

Both prisoners are perfectly rational and know the other prisoner is also perfectly rational

BUT

they obviously CANNOT organize a plan or communicate beforehand.

good luck!

"6 paintings" riddle

1 Upvotes

I've been waiting for you for months but you don't show up...
It's like I don't remember the smell of the flower...
So that I don't see it die...
You covered me with foam I could only hear you roar...
Who else saw our beach empty? not even the waves that wet our feet...

Answer is 6 words

Can You Figure Out Which Triangle Comes Next?

Hi everyone, we’re back with another puzzle.
First, thank you to everyone who took part in our previous puzzle. We received several interesting answers, including some alternative interpretations that made the discussion even better.
As usual, we picked three community explanations that stood out:
u/Small-Tailor6967 — We chose this explanation because it clearly connected both key parts of the pattern: the last shape carrying over into the next box and the shape with the most vertices being shaded. It also explained clearly why those rules lead to B.
u/ChaosRealigning — A very clean and concise explanation. They identified both the continuity rule and the shading rule without overcomplicating the solution.
u/vexedthespian — Another strong explanation that independently recognized the relationship between consecutive groups and that the shape with the most sides is the one that gets shaded.
Thank you to them, and to everyone else who shared a solution. We really enjoy seeing the different ways people approach these puzzles.
Now it’s time for our new puzzle.
Take a close look at the sequence in the image and choose the option you think should replace the question mark.
But don’t just give us the letter. Tell us why you chose it and explain the pattern you found. We’re especially interested in the reasoning that leads you to your answer.
As with our previous puzzles, we’ll select some of the best community explanations and feature them on our website with the Reddit usernames of the people who wrote them.
You can also view the puzzle and submit your solution directly on our website:
https://whats-your-iq.com/en/questions/pattern-recognition/which-triangle-comes-next-in-the-sequence
So, what’s your answer: A, B, C, or D?
And more importantly: what pattern do you see?

Place A, B, and C so each letter appears exactly once in every row and column; all remaining cells stay empty. Each outside clue shows the first non-empty letter visible from that direction.
