TKKG and the 12,000 Detectives is a first-of-its-kind audio play that transformed a passive medium into an immersive and interactive experience. A cross-platform adventure blurring the boundaries between audio play and game by using WhatsApp. To maximize immersion and interaction, our humanized bot simulated TKKG’s characters and responded to freeform questions. We encouraged fans to use different platforms and media to collaborate and solve the riddles together.
