Abstract: Provided is an information processing program for causing a computer to realize: a joint-event generation management unit that consumes a first parameter and generates a joint event; a number-of-players determination unit that determines an upper-limit number of players allowed to participate in the joint event; a joint-event participation management unit that consumes a second parameter and that permits other players to participate in the joint event; a privilege management unit that grants an execution privilege for the joint event to a player; a joint-event execution control unit that starts the execution of the joint event when replies have been accepted from all the players except the player who has been granted the execution privilege; a reward providing unit that provides a reward to each player; and a joint-event number-of-times checking unit that checks whether the number of times for execution of the joint event has reached the upper-limit number.
