Abstract: A network game system preventing unfair operation and providing players with thrill and excitement is disclosed. In a link tag for hypertext, a back prevention counter value for identifying the hypertext is included. The counter value is also stored in a database. When a player presses a link button to send a URL, i.e. a game command, (S210), the counter value for the player is read out from the database (S212). The back prevention counter value included in the received URL is compared with the readout back prevention counter value. When the two values do not match, the player is informed that unfair operation is prohibited (S214). The link tag may also include time information, so that a deadline for transmission of a game command using the link tag is set by employing the time information.
