Apparatus, method and program for managing network of game machines

摘要

A management database stores data about a game session expressed in terms of reference time, and data about time differences between the reference time and the standard times of each country or region. The indication of each of game-playing time-periods collected from game machines which are located at random in various countries or regions, is converted from the standard time to the reference time. The game-playing time-period indicated in the reference time is compared with the game session data written on the basis of the reference time in order to determine whether or not the game-playing time-period is within the game session. Then based on the data regarding the play results within the game session, the game ranking is determined.
