Three men sit in chairs (#1, #2, and #3), in a straight line, all facing north, one behind another.  Each man will have a hat placed on his head.  No one can see his own hat at any time.  The man in Chair #1 is in the front, he cannot see anyone else.  The man in Chair #2 is behind Chair #1 and he can only see the man in Chair #1.  The man in Chair #3 is behind Chair #2 and he can see both men in Chairs #1 and #2.  

 

On the table, there are three blue hats and two white hats.  Each of the three men will be randomly given one of those five hats and two will be discarded.  No one will know the color of the discarded hats or the color of his own hat.  The first person to use logic to determine what color hat is on his own head wins.  

 

After five minutes, the man in Chair #1 stands up and says, "I win.  I know the color of my hat."

 

The riddle is: What color was it, and how did he figure it out?

Answer below in white 

#1 reasoned that:

#3 sees at least one blue hat because if there were two white hats in front of him, he would stand up and declare that he has a blue hat.

#2 didn't stand up because there is at least one blue hat between #1 and #2, and #2 sees a blue hat.

Sunshiny is correct!  Well done!  Have you a riddle to trade?

Sorry, no

number 3 only knows if 1 and 2 have white.
Number 2 knows if 1 has white and number 3 doesn't win. or if 1 has white and 3 wins.

Number 1 has to be blue.

I know a different one that's basically the same, including 2 of each hats and a wall.

But never mind, here's a new riddle.

There's a room with 3 lightbulbs in it, let's say they are all off. The room is closed by a door and you are outside the room. There are 3 switches, each belonging to a light bulb. You can only enter the room once.

How can you determine which bulb belongs to which switch?

I think i got it:

Flip on a switch, go in and take note of which switch turned that on. Remove a light bulb from one of the other two sockets. Go out, turn the first switch off, and switch on a different switch. If a light appears under the door, then it belongs to the one with a bulb.

Vivinski

no it's more practical than that, no looking under the door

Does it require knowledge of wiring or something? Like possibly the middle switch will always be connected to the middle light?

How about this:

Flick on one switch. Wait a while, then turn it off. Flick on the next switch and enter. The second switch flicked will be lit, and the first switch will correspond with the warm bulb.

Vivinski

that's correct

The cold was correct!

What does one love more thatn life?

What does one fear more than death, or mortal strife?

What does the poor have, the rich require,

And what the consented man desire?

What does the miser spend, the spendthrift save?

And all men carry to their graves?

And the answer is...:

tigbench

Nothing

There is nothing one fears more than death or mortal strife, and there is nothing one loves more than life.
