Mimicking the "Music Quiz" game on iPods, the iGAMEz from Pressman lets you play "Name that Tune" on any MP3 player. First everyone plugs in their players to the unit, then the host picks a song, and the first person to guess it right gets a point. The catalog isn't quite clear on how it works and why you need everyone to plug in their MP3 players, but we're guessing it's probably to act as a buzzer to indicate that you know what the song is. We think.
Works with 2-4 players.
