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.
