A very well-known game principle in a box published by Parker in the 1990s. The principle of Amnesia is very simple and very well-known.
Participants have a card on their forehead (it is held in place by a blindfold).
We see the contents of other people's cards but not our own.
Each card features the name of a celebrity (ranging from Frankenstein to Humphrey Bogart to Bambi).
Players must uncover their hidden identities by asking questions that other players can only answer with "yes" or "no." If the answer is "yes," they can ask a new question; if the answer is "no," their turn ends.
The first to discover the character on their card wins!
