What is the yes and no game in A Christmas Carol by Charles Dickens?

The 'Yes or No' game appears in stave 3 of A Christmas Carol, when Scrooge is  visited by the ghost of Christmas present. During his visit, the ghost takes Scrooge to the home of his nephew, Fred, where they are playing the 'Yes or No' game. Dickens then informs the reader of the aim of this game: 

"It was a Game called Yes and No, where Scrooge's nephew had to think of something, and the rest must find out what; he only answering to their questions yes or no, as the case was."

This game is very similar, then, to the modern game called Twenty Questions, in which someone takes the identity of another person and the other players have to guess who that person is, by asking questions which can only be answered with a 'yes' or 'no.' 

The purpose of the 'Yes or No' game in this stave is to demonstrate to Scrooge how his miserly ways have impacted how people feel about him. When playing the 'Yes or No' game, Scrooge is likened to a "savage animal' and mocked by Fred and his guests.
