In 1965, with Sills and others, Spolin co-founded the Game Theater in Chicago, and around the same time organized a small cooperative elementary school (called Playroom School and later Parents School) with Sills and other families in the Chicago area. The theater and the school's classes sought to have audiences participate directly in Theater Games, thus effectively eliminating the conventional separation between improvisational actors and audiences. The theater experiment achieved limited success, and it closed after only a few months, but the school continued to use the techniques, alongside a regular elementary curriculum, well into the 1970s.
