Abstract: A method of gaming between multiple participants, each of whom has a locationally aware smart phone or similar user device with a microphone and at least one speaker, capable of a triggering interaction with other such devices using a sound-based trigger. A gaming session is triggered by the playing of an acoustic gaming session request tone by a first device. Software on other user devices within acoustic listening range which “hear” the trigger tone can cause the listening devices to join a gaming session with the first user device through contact with a centrally administered gaming application on a server. Based on the geographic location of the gaming session, or other applicable user parameters, at least one game or contest from the server is made available and can then be selected and played between the connected user devices, served by the central system.
