  "The players may not communicate in any way" - It seems to me that all the answers are a form of communication. In fact the dictionary defines communicate as, "share or exchange information."

    What a joke: "find a strategy for the players to determine the colours of their hats based on the hats they see and what the other players do" I interpreted it in the same way as you did - communication on any level is not allowed. If there is no sharing of information then I think it is impossible to solve the puzzle.

      It is possible without communication (also without seeing what the other players do).

  To me it looks like a mix between the Prisoner's Dilemma (https://en.wikipedia.org/wiki/Prisoner%27s_dilemma https://en.wikipedia.org/wiki/Prisoner%27s_dilemma) and Blind man's bluff poker (AKA Indian Poker) https://en.wikipedia.org/wiki/Blind_man%27s_bluff_(poker) https://en.wikipedia.org/wiki/Blind_man%27s_bluff_(poker)
