BackChatter is a game about predicting Twitter trends. Designed to be played at conferences and other events, beating BackChatter means
sharpening your socio-linguistic smarts. BackChatter was prototyped at the 2009 Games for Change Festival and IndieCade 2009 and premiered at the 2009 Games, Learning, and Society Conference, where Electronic Arts generously provided prizes for the winners of each round and the overall game winners. The final official run of Backchatter was at the Game Developers Conference 2010 where it was co-hosted by Local No. 12 and the IGDA with support of Arkadium.
Backchatter is a game designed by Local No. 12
In 2010 BackChatter was released open source. It has since been played at conferences worldwide including CHI 2011.
