Abstract: A video game system has a host and a plurality of terminal devices connected to the host through transmission lines. The terminal device has a plurality of game units on which a video game program is played. A first memory is provided in the host wherein a plurality of video game programs are stored. The video game program is transmitted to the terminal device. A second memory is provided in each of the terminal devices for storing the video game programs transmitted from the host. Information on points of the video game program scored on each game unit is transmitted to the host. The order of the points is determined at the host based on the point information. Each order of the points is transmitted to the corresponding game unit to indicate the order on the display of the game unit.

The video game program is transmitted to the terminal device. A second memory is provided in the terminal device for storing the video game programs transmitted from the host. A third memory is provided in the game unit for storing information on playing condition of the video game program. A video game program stored in the second memory is determined to be replaced by a new video game program stored in the first memory in accordance with the information stored in the third memory. The new video game program is transmitted to the terminal.

Abstract: A plurality of terminal devices through transmission lines, receive video game programs transmitted from a host. The host has a first memory storing the video game programs, and each terminal device has a second memory for storing video game programs sent from the host. The terminal devices is designated by a terminal device identification data. The video game program is constituted by a start packet, a data packet, and an end packet. The start packet includes a start packet identification code for indicating that the packet is a start packet, a first terminal device identification data for identifying the terminal device to which a video game program is transmitted, a game program identification data for identifying the video game program to be transmitted.
