I hope all of you have read the book ‘Da Vinci Code’ (or have seen the movie). I think the most important thing in the story is the strategy played by the different players. I just got amazed that in a story so many use of game theory can be possible. Start from the preface when the curator was asked about the secret he said “I have no idea what you are talking about!” because he did not know that how much albino Silas knew. So it was a type of asymmetric game between Silas and Curator. He tried to save himself in the way of arising doubt to Silas. Silas then revealed that in this case as well his best strategy is shooting off the curator. Curator then told a lie he had rehearsed from very before knowing that he is in danger knowing the secret. There was no way of verification of his word as all others who knew it, will also say the same. The dominant strategy here was telling the lie even if other brotherhoods are also murdered. Now it was the turn for Silas. Silas had the option not to shoot but then also he will get trouble in further turns in terms of arrest for an attempt to murder.
Let us see now through the first chapter of the story when Captain Fatche suspected Langdon for the murder. If Langdon really killed the curator then he will try to divert police in different way using his code breaking skill. He had although an information asymmetry regarding that he was suspected by police. Police have the option to know the right using their own cryptographer. Here also Captain Bezu Fatche created an information asymmetry by rubbing up the letter “call Robert Langdon”. Now it was the turn of Sophie who had better information than Fatche as she was the granddaughter of Curator. She had to reveal out all the truth so she helped Landon to fly away.
I think you could find out lots of other games... Just try out.
