There were three prisoners, one of whom was blind. Their jailor offered to free them all if any one could succeed in the following game.

The jailor produced three white hats and two red hats and, in a dark room, placed a hat on each prisoner. Then the prisoners were taken into the light where, except for the blind one they could see one another.

The game was for any prisoner to state correctly what color hat he himself was wearing. The jailor asked one of those who could see if he knew and the man answered no. Then the jailor asked the other prisoner who could see and he answered no.

The blind prisoner at this point correctly stated the color of his own hat winning the game for all three. How did he know?
