Further, in order to reduce the burden of creating the score distribution table and summed score distribution table, and the estimating process of the ranking in the game terminal 1 , the distribution partition number may be decreased.
  • the distribution partition number can flexibly be modified according to the status on the score server 3 .
  • the threshold update unit 306 updates the distribution partition number along with the update timing of the threshold in the first embodiment and when the distribution partition number is updated, the threshold transmission unit 303 transmits the distribution partition number to the storage server 2 along with the transmitting timing of the threshold.
  • the progress status information storage unit can simultaneously store a plurality of game progress status information, so long as it is possible to include the game identification code that identifies the game played to the progress status information, and store in association with the player identification code. More specifically, as in the typical memory card that is not of exclusive use for individual games, the progress status information storage unit can store the progress status information.
  • the score server provides a ranking memory unit and a threshold memory unit for each type of game.
  • the storage server holds different threshold storage units for each type of game.
  • the progress status information transmission unit of the game terminal transmits the progress status information to the storage server, it is only necessary to transmit it along with the game identification code that identifies the game that was played.
  • the score transmission unit of the storage server only needs to transmit scores so long as the score that is included in the transmitted progress status information is equal to or above the threshold stored in the threshold storage unit associated with the game identification code.
  • the score server receiving the scores stores the scores in the ranking memory unit that is associated with the game identification code. This enables acquiring the ranking for each type of game.
  • the read-out request transmission unit of the game terminal may specify game identification code along with such as player identification code, and the read-out request transmission unit of the game terminal may transmit the read-out request to the storage server. Then, the progress status information read-out unit may read out the progress status information that is stored in association with the specified game identification code and the player identification code.
