Post your puzzles here on the Puzzle Post:
And I see no reason why multiple puzzles/lateral thinking riddles/etc. cannot exist side by side at the same time as long as the potential solvers of said puzzles make it clear which one they were replying to.
Here is a starter-off and probably the best puzzle I have ever encountered in my life.
I'm not sure how famous this puzzle is so if you already know the answer please do the respectful thing and leave it to those who have not already had the enjoyment of figuring it out to...figure it out...
Four people are in a room, labelled A,B,C,and D...
Each wear either a black or a white hat, as shown in the illustration below:

Each person faces to the left.
Each person cannot see the colour of the hat they are wearing.
Each person knows their A,B,C,D order, meaning that they know how many people are in front of them and how many are behind them.
All of the people know that there are 4 people in the room.
All of the people know that there are 2 white hats and 2 black hats.
They are not allowed to turn around or speak to each other.
The black bar labelled W represents a wall dividing the room which cannot be seen through, nor is it a mirror (no cheap tricks like that).
A can only see the wall right in front of them.
B can only see the wall right in front of them.
C can see the colour of B's hat.
D can see the colour of B's hat and C's hat.
The object of this puzzle is to determine which person will first correctly and with 100% certainty be able to say if they are wearing a black hat or a white hat, and also be able to explain how they knew.
SO:
Which person knew the colour of the hat they were wearing and how did they know?
