Full description

It's your first day as a janitor at Caltech when you stumble into an abandoned lab and press a large red button. A handwritten note appears: a nuclear bomb has been armed and eight devices are hidden across Pasadena to disarm it. You have no choice but to run.

This self-guided spy mission takes you on an 86-minute adventure through Old Town Pasadena. Using the Questo app on your smartphone, you decode secret messages, crack clues at historic landmarks, and follow a conspiracy connecting Caltech physicists, the Manhattan Project, and Albert Einstein.

Chase the trail from Vroman's Bookstore to the Pasadena Playhouse, through hidden cobblestone alleys and past City Hall, all the way to a famous mural of Einstein on his bicycle.

Start whenever you like and play entirely at your own pace across 3 kilometres of Pasadena's most storied streets.

Perfect for curious explorers, couples, and families. No prior knowledge of history needed, just a sharp mind and a sense of urgency.
