Abstract: A game device is provided which can connect to a plurality of wireless controllers. A game device of the present invention has a plurality of communication modules, each serving as a master, which can wirelessly connect to slaves. One communication module performs an inquiry procedure for establishing a connection with a plurality of slaves, and the other communication module performs no inquiry procedure. The communication module that has issued the inquiry transmits, to a control unit, information relating to a slave that is not connected to the module itself, and the other communication module acquires the information from the control unit, thus obtaining information necessary for establishing a connection with a slave. This allows for quickly establishing a connection with a slave.

Abstract: According to a game system, the communication period between a radio controller serving as a slave and a game device serving as a master can be made variable in a power saving mode. In a scene which requires a certain real-time level, the communication period is shortened, while in a scene which does not require a certain real-time level, the communication period is elongated. This variability of communication period as appropriate in the power saving mode can reduce power consumption without degrading the game characteristic.
