Three or more people are wearing hats of various colors. Each person can see the color of all the hats but his own. Communication between players is either restricted or not allowed at all. Players must use their powers of deduction to determine the color of their own hats. This premise is at the basis of a number of intriguing puzzles. In this session we consider some problems of this type, among others. See the attached files for the problems and solutions.
