Abstract: A controller causes a display unit to display N candidate values selected from natural numbers in a target range having a predetermined base value as the maximum value, as candidates to be selected by a user. The controller selects M values that are multiples of a plurality of different reference values, from among the natural numbers in the target range as candidate values, and causes the display unit to display a candidate value list that lists N candidate values that include the M values.

Abstract: A game apparatus provides a game in which a plurality of target characters are selected from a plurality of possessed characters owned by a player and are applied to an event. A storage unit stores, for each character, the required value for selection required to select the character and the attack power of the character. A controller selects the plurality of target characters from the plurality of possessed characters such that the total attack power, which is the total of the attack power of the plurality of target characters, is maximum under the condition that the sum of the required values for selection of the plurality of target characters is equal to or smaller than a permissible value for selection given to the player.

Abstract: A transaction process, such as a charging process, can be restricted from being repeatedly performed when a data item that has been downloaded once is to be redownloaded. A charged data table including user identifying information and the name of a charged data item associated with each other is prestored in a charge management DB. When a data provision request is made for the charged data item, the charging process is skipped at a data distribution server, allowing the data item to be downloaded without any charging process.
