Abstract: A game period is common among a plurality of users and includes a first period and a second period. An example information processing system advances a first game for each user in the first period. A rank of each user is determined based on a first individual parameter of the user for the first game from a past game period. A second individual parameter is determined for each user based on the rank of the user and the first individual parameter of the user for the first game from a current game period. In the second period, the information processing system determines a common parameter that is common among the plurality of users based on the second individual parameters for users who have performed a particular game input so as to advance a second game that is common among the plurality of users based on the common parameter.

Abstract: In the case where a maximum number of valid objects that is a number equal to or less than a maximum number of designation objects is decreased from a first number that is equal to or greater than 2 to a second number that is equal to or greater than 1, the second number of the valid objects is maintained, and the valid objects, the number of which is a number by which the second number is exceeded, are changed to invalid objects. An individual parameter that is changed in accordance with game play is associated with each object. In the case where designation of a designation object is cancelled, the individual parameter thereof is set to an initial value. In the case where change to a valid object is made after change to an invalid object, the individual parameter immediately before being changed to the invalid object is maintained.

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 competitive game consisting of a plurality of turns. In each turn, one or more candidate objects, which are selected by a user from among a plurality of candidate objects placed in a first area, are placed as ally objects in a second area in a battle area. One or more enemy objects are placed in a third area in the battle area. The information processing system, based on the positions of placed objects that are the ally objects or the enemy objects placed in the battle area, determines, for each placed object, an attack turn, and an attack target out of the placed objects. The information processing system executes an attack on the attack target by the placed object according to the attack turn, thereby decreasing a life parameter associated with the placed object that is the attack target.

The information processing system adds at least one skill that satisfies a condition for being designated by the user, among the plurality of skills, to the possessed character on the basis of designation by the user. In a second game different from the first game among the plurality of games, a use character prepared to be used in the second game is used. The information processing system adds at least one skill among the plurality of skills to the use character in accordance with progress of the second game.

Abstract: A plurality of characters with which outer appearance images and game parameters are respectively associated, even several characters having the same outer appearance images are individually managed, and a game is executed using the plurality of characters possessed by a user. For a specific character designated by the user among specific characters for which a change allowing condition for the outer appearance image is satisfied, the outer appearance image is changed to a first image set in advance in association with the specific character or a second image that has become selectable by the change allowing condition being satisfied, on the basis of a user's instruction. 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 stores therein first ability data indicating abilities of possessed objects used in a first game. A use object to be used in a second game is selected from among the possessed objects. Second ability data indicating an ability of the use object is set so as to indicate an ability lower than the ability indicated by the first ability data of the possessed object that becomes the use object. When an update condition regarding the use object has been satisfied during execution of the second game, the second ability data is updated such that the ability of the use object having satisfied the update condition is strengthened. Regarding the update of the second ability data, an upper limit is set on at least a part of the ability of the use object, based on the ability indicated by the first ability data.
