The Hats
There were 4 people sitting in a row trying to win $50 from a riddle.
The one in front was wearing a red hat.
The second from the front was wearing a blue hat.
The third from the front was wearing a red hat.
The last was wearing a blue hat and was blind-folded.
Each of them was informed that they were all wearing a hat, the last person was blind-folded and that there were 2 red and 2 blue hats. If they can guess the color of their hat, then they win the prize.
There was a long silence, then one of them guessed the color of his hat correctly. Who was it?
(Note that they can only see the person in front of them and are not allowed to turn around and see behind them.)

Answer
It was the second person. The first and last person cannot see other people at all, therefore it is either the third or second. The second person realised that if he and the person in front were wearing the same colored hat, the third person would be able to answer the color of his hat right away. However, since there was a long silence, then the color of his hat and that of the person in front must be different.Hide Answer Show Answer

I thought you meant they could only see the person DIRECTLY in front of them. That would have been impossible...I guess it's my fault I didn't understand the wording.. Good teaser, anyway.
great job
I like your logic puzzles Trillionaire. Do-able but requires enough effort to make them challenging and fun.
I agree with bookwrmKP that there is a mistake in this riddle. If one can only see the colour of the PERSON in front, then it can't be solved. It should say PERSONS instead.
I agree with the two criticisms. The way the puzzle was worded, it seems that each person can only see the person in front, not the PEOPLE in front. Hence, there would be no solution (as worded.) I think if you re-write it, it would be quite a fun puzzle...
