They were playing charades
Jacobs return was the start of the changes that Scrooge was to undertake before Christmas Day. Marley tells Scrooge that he (Marley) will walk the earth for eternity because of his attitude to his fellow man. It was a punishment that he did not want Scrooge to endure

Himself
When young, Scrooge worked for Mr. Fezziwig, a genial and generous man.
He teaches Scrooge that you can change your future if you become a better man.
The dead man was Ebenezer Scrooge's former partner, Jacob Marley. Scrooge discovered who it was when Marley's ghost appeared to him in chains to deliver a warning about his impending fate if he did not change his ways.
Scrooge wanted to watch his nieces and nephews play "Blind Man's Buff." This game is featured in Charles Dickens' "A Christmas Carol," reflecting the joy and innocence of childhood that Scrooge initially overlooks. The game symbolizes the festive spirit and familial connections that Scrooge learns to appreciate throughout the story.
Ignorance and Want are two children hidden beneath the robes of the Spirit of Christmas Present. At the very end of the Spirit's visit, Scrooge notices two "claws" protruding from underneath. The Spirit parts his robes to reveal the boy and girl, both of whom are in an awful condition. When Scrooge asks to whom they belong, the Spirit answers, "They are Man's." It is, however, the boy that the Spirit especially warns Scrooge against. Ignorance must be erased, the Spirit seems to say, or he spells doom for the race. When Scrooge asks if there is no refuge or resource for the children, the Spirit turns Scrooge's own words against him. "Are there no prisons? Are there no workhouses?" These are the last words Scrooge hears from this visitor.
