This program simulates a simple version of the party game Mafia This game is strictly multiplayer and needs at least 5-6 players to have a meaningful game.

The game is played through sockets. You can connect to the server with the telnet command or the WebSocket layer with the HTML5 client included with the server. When the terminal opens in the browser, type connect <ip> <port> to connect to the server. This client can be found in the client directory.

This game requires the gems eventmachine and em-websocket to run.

Once these gems are installed, open config.rb to configure the server. (see section on setup if the setup key doesn't make sense)

ruby server.rb

Now connect to the server using telnet or the HTML5 client.

• Villager: sleeps throughout the night
• Mafia: collectively kill one player each night
• Cop: investigates one person during the night
• Doctor: can "save" one person during the night. If this person was targetted by the Mafia, he will not die.

The setup tells the game what roles to assign to people. For example, if the setup is configured as the hash

{ Mafia => 2, 
  Cop => 1,
  Villager => :excess }

then the game will assign 2 players the Mafia role, 1 player the Cop role, and any more players that join the Villager role. Note that you can have multiple :excess roles. Extra players will be assigned to them randomly.

The setup can be changed by the host before the game starts with the set command and can be viewed by anyone with the setup command.

doctor.rb is a file containing the doctor role in its entirety. It serves as an example of an added role - if the role is simple enough, no internal modification is necessary to add it.

The HTML5 client uses the WebSocket API to connect to the server. The only requirement is a modern browser.

It uses jQuery and jQuery terminal emulator.
