Apple has removed the standalone Game Center app from iOS devices with the release of iOS 10, but Game Center-like features are still available within individual apps that utilize Apple's GameKit. Users can send multiplayer invites through the iMessages app to people in their contacts or other players. Invited players will receive a "rich link" to join the sendee in the game. Users who do not have the game installed on their device will be directed to the App Store to download the game.
