Hats again - One puzzle a day - Puzzle Buddies

Puzzle:Inside of a dark closet are five hats: three blue and two red. Knowing this, three smart men go into the closet, and each selects a hat in the dark and places it unseen upon his head.Once outside the closet, no man can see his own hat. The first man looks at the other two, thinks, and says, “I cannot tell what color my hat is.” The second man hears this, looks at the other two, and says, “I cannot tell what color my hat is either.” The third man is blind. The blind man says, “Well, I know what color my hat is.” What color is his hat?

Solution: The first man can only say that he does not now what color hat he has when other two hats he is seeing are "red" and "blue". Second man also said same thing which means he is also seeing one red and one blue hat. Now there are only two red hats so first and second both are wearing Red hats and third person is wearing the blue hat.
Winner: Once again Kasturi is the winner.

  1. If man2 and man3 both had red hats, man1 would have known that he has a blue hat. But he does not. So, atleast one of man2 and man3 has a blue hat.
    Given this, if man3 had a red hat, man2 would have known that he has a blue hat. But he does not. So, man3 has a blue hat.

  2. OMG, what are 3 men doing in the closet? "Hats" is that what they are calling it?

  3. Hat is White, but i don't know just cause it's covering your head and face doesn't really mean it's called a hat...

  4. I think black AND blue would be the correct answer. Did this happen in a jail cell? Also please replace word "hat" in puzzle with "balls".
