The Twenty-Sided Tavern is an improvised quest play. Relying on audience participation, each performance is uniquely tailored to decisions made by audience members on their phones using patented software from Gamiotics. Audience members choose which characters will appear each evening, as well as which paths they will take, and which decisions they will make along the journey. The in-mobile-browser platform does not require any special equipment, instead running on audience members' phones.
