Abstract: A system, machine-readable storage medium storing at least one program, and a computer-implemented method for matching players of a game is provided. A game networking system receives a request to play a game against a second player outside of a social network of the first player. The game networking system sends the request to a second client device of the second player. The game networking system receives, from the second client device, an acceptance of the request to play the game. The game networking system generates a match associated with the game in response to the acceptance. The game networking system provides a communication channel between the first player and the second player in response to the match.
