The 'prisoner hat riddle' might just be the most frustrating riddle yet. 


This riddle was posted by Ted-Ed and it's got the whole office kicking themselves that they didn't figure it out. 

Give it a go and let us know how you went! 

You and nine other individuals have been captured by super intelligent alien overlords

 

The aliens think you look super tasty... BUT they have a rule about not eating highly intelligent, logical beings.

 

... But... they're not too sure whether or not you qualify. So, they decide to give you a test! 

 

It goes as follows... you will be placed in a single file line, facing forward and in size order. This way each of you can see everyone lined up ahead of you. 

You cannot look behind you or step out of line. 

Each of you will have rather a black or a white hat that will be assigned randomly and you won't know how many of each hat there are. 

 

 

When the alien says so, you all have to guess the colour of your hat. The person in the back will start, then the person in front of them, and so on.  

You can't say anything other than "black" or "white" and you cannot  signal in any other way or you will be eaten. 

If at least nine of you guess correctly, you'll all be spared. 

 

The alien then gives you all five minutes to discuss a strategy to save yourselves. 

Can you think of a strategy that will save everyone? 

Below is the full riddle. The answer is revealed at 1.40 minutes in.
