This system manages web points and game points used in a web service and a game service and converts a user's web points into game points for update of the user's game points when the user uses the game service, and includes a user point database, a web server, a game server and a channel server. The user point database stores and manages the web points and game points for each user. The web server provides a user with the web service by referring to the web points stored in the user point database. The game server provides the user with the game service by referring to the game points stored in the user point database. The channel server provides the user with channel-related data for each game, allows the user to play a game through the game server in a specific channel selected by the user, converts the user's web points stored in the user point database into corresponding game points when the user enters the specific channel, and updates the user point database by adding the corresponding game points to the user's game points stored in the user point database.
