Your source for free multiplayer online games!

• Free - The game must be completely free to play indefinitely, not just for a trial period. The game may however charge to unlock special features or areas, or to give the player some advantage or benefit that non-paying players don't have.
  
  
• Multiplayer - Playable by more than two players in the same game at the same time.
  
  
• Online - Playable over the internet.
  
  
• Realtime - A player's actions take effect immediately. This is as opposed to turn-based or tick-based games.
  
  
• Graphical - The game must have a graphical interface. Text MUDs, for instance, don't qualify.
