The classic parlor game of CHARADES, which consists of 8 letters, is a game in which one player acts out a word or phrase without speaking, and the other players must guess what it is. Twenty Questions, which consists of 15 letters, is a game in which one player thinks of an object and the other players take turns asking yes or no questions to try to guess what it is. Both of these games are popular party games that have been around for centuries.
