Which process is used for sending invitations to players to start a game?

In Game Center, a match is formed when a group of players want to play a game together. Each player plays the game on their own device, and the experience on each device is tailored to the player playing on that device with the match as a whole representing a shared experience. To accomplish this, the instances of the game share data with each other so that there is agreement about the state of the match.
