Abstract: A system and method are described for providing a game of chance over messaging services. In one embodiment a method is disclosed for receiving a message from a first user which includes an identifier of a second user. The second user is registered for the game of chance based on the identifier of the first user. A message may be sent to the second user to invite the second user to enter the identifier of another user into the game of chance. A winning identifier is identified from a set of identifiers, such as the identifiers entered into the game of chance. A message is sent the second user if the amount by which the identifier of the first user matches the winning identifier satisfies a winning threshold. The message may include an indication that the second user won a prize.
