Claim:
A game system including a first game apparatus and at least one second game apparatus which can carry out short-range wireless communication with one another, wherein said first game apparatus comprises: a first transmitter which transmits a predetermined number of pieces of first verification data to verify a wireless communication state to said second game apparatus, wherein the predetermined number of pieces is greater than two; a first receiver which receives second verification data transmitted from said second game apparatus; number-of-received data detecting programmed logic circuitry which counts the number of the received pieces of data of second verification data received by said first receiver, wherein the counted number of received pieces of data is the same as or fewer than the predetermined number of pieces of first verification data and the counted number depends on the communication state; and first game processing programmed logic circuitry which varies a game process according to said counted number of the received pieces of data, and wherein said second game apparatus comprises: second receiver which receives said first verification data transmitted from said first game apparatus; and a second transmitter which transmits the same number of pieces of the second verification data as those of the first verification data received by said second receiver to said first game apparatus.
