Guess Who? which is designed for two-players, is marketed as “The original guessing game” and was launched in 1979. Each player chooses a mystery character and then using yes or no questions must try and figure out the identity of the other's chosen character. Guess Who? is a fun game for the majority of the family, suitable for ages six to 106, and the “Grab & Go” compact version is handbag size making it ideal for holidays, days out and for children to take to their friend’s house.
