Abstract: An example of a terminal apparatus designates a use object to be used in a competitive game from among a plurality of objects each being associated with an object parameter, based on a user's operation input. The example of the terminal apparatus designates a designation parameter indicating a value or range of the object parameter, based on a user's operation input. A matching request including information regarding the designated use object and information regarding the designated designation parameter is transmitted to a server. An example of the server determines, as participating users, users of two terminal apparatuses, among a plurality of terminal apparatuses, which are in such a relationship that the value of the object parameter of the use object included in the matching request of each terminal apparatus corresponds to the value or range of the designation parameter included in the matching request of the other terminal apparatus.

Abstract: An example of an information processing system sets any one of teams in a competitive game into an operable state. During the competitive game, the information processing system causes an object included in a team in the operable state to perform at least one of a plurality of types of actions including battle, based on an instruction by a user associated with the team or on a control performed by the information processing system. A first evaluation value is calculated based on the result of the battle. Each time the progress state of the competitive game satisfies a condition, a second evaluation value is calculated based on the number of objects placed in a predetermined area in a game space. The information processing system determines a winner and a loser in the competitive game, based on the first evaluation value and the second evaluation value.

Abstract: An example information processing system executes a process using values of scores of a plurality of users that are updated based on a result of a game. When a first game is selected from games, the first game is executed, in which the result of the game is determined based on a first user's game operation in the first game, and an opponent based on data of a second user different from the first user. When a second game is selected from games, the second game is executed, in which the result of the game is determined independently of the first user's game operation performed in the second game. The information processing system updates the first user's score and the second user's score based on a result of the first game, and updates at least the first user's score based on a result of the second game.

Abstract: An example of an information processing system executes a draw for choosing one or more game character based on selection probabilities from among a group of game characters, wherein at least one of the game characters chosen by a draw is granted to the user. When a game character of a first group is granted by a draw, a first selection probability value for game characters of the first group is changed to a first base value, and a second selection probability value for game characters of a second group is changed to the second base value. When a game character of the second group is granted by a draw and a boost value of the first selection probability is greater than a predetermined value, the first selection probability value is at least lowered so that the first selection probability value is greater than the first base value.

Abstract: An example of an information processing system is configured to, in a draw mode, display two or more selection candidates. In the draw mode, when a selection instruction to select at least one of unselected selection candidates is given, a game character that corresponds to the selected selection candidate is granted to the user. When the number of unselected selection candidates is equal to a first number, the process decreases an amount by which the predetermined parameter is decreased as compared with a case where the number of unselected selection candidates is equal to a second number greater than the first number. When a cumulative grant count becomes equal to or greater than a reference count, the information processing system permits execution of a designated mode in which a game character designated by the user is granted to the user.

Abstract: An example of an information processing system executes an application including a plurality of games using characters to each of which at least one of a plurality of skills influencing progress of a game is added.

Further, the game parameters of all the specific characters for which the change allowing condition is satisfied are changed.

Abstract: An example of an information processing system includes a server capable of communicating with a terminal device. The server stores information representing a choice probability, for each of a plurality of objects in the application, for a draw whereby a user obtains an object. The information processing system accepts an instruction of specifying a relevant object to be associated with the draw. The server alters the choice probability at least for some of the objects depending on the relevant object. In response to a draw instruction, the server chooses at least one object from among the objects that can be obtained through a draw based on the choice probability obtained by altering the choice probability. The server awards one or more of the chosen objects to the user.
