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.

Bravo Again, Questo!

This was a tough one! You'll need hints. But it's worth it. I learned a TON about Pasadena history, and the puzzles were clever and led to some of the most interesting stops in the city. In the end, I was very glad I did it. Bravo again, Questo!

Operator response

Ok, but flawed

The game was mostly fun. Once we figured out the level of the puzzles/clues (easier than we had been making it), they were quick solves. (Seriously, we're talking on the level of "look and spot the answer," made to look slightly more challenging by having a couple words in the clue upside-down or scrambled.) I enjoyed a clock one, because it actually involved a tiny bit of thought. The good news: I've played other scavenger hunts where things are not there anymore. This is not the case; this hunt depends on historic things that aren't going to move. The bad news: Two maps are wrong. Like, objectively wrong. One directs you to an address on the wrong street (a couple blocks from your actual destination); another sends to the current site for a particular structure when the quest wants you to go to the historic site blocks away. (Also, one puzzle is wrong, asking for the number of "rows" of a certain thing, when the answer is the number of things.) I sent both of these complaints to the company (in response to their request for a review). Several days went by, but no response. I had expected a "thanks for your input; we'll look into that" - none of these things would've been a difficult fix. But I guess they'd rather have future players running in the wrong direction and getting angry when their correct answer is rejected than actually fix the game.

What you see is not what you get.

I googled looking for a tour of city hall and didn't realize that's not what the image represented. I didn't use the tickets

Fun informative exercise

We found ourselves with extra time in a city we didnt know anything about. The game showed us places we never would have seen and added a lot of historical information.

Buggy App

The app was buggy. It was fun but frustrating at times. The point on the map was not the actual location. This frustrated my family and took away from the fun.
