Abstract: An interactive live sports game watching system includes a game web server internally built a plurality of game-related web pages showing user-accessible game information, and at least one remote game watching device linked with the game web server for receiving live sports games telecasting and entering the game-related pages to search for game information or input predicted results of an underway game and bet corresponding membership points on the game. The game web server compares the predicted results with real results and counts points added to or deducted from the membership points. Therefore, a user may watch the live sports game while looking for basic information about the parties in the game or historic events in connection with the game, and get more fun from predicting and betting on the game.
