The case file · written by Questo Originals

A serial killer left a cipher behind. He dares you to crack it.

Decades ago, the Zodiac Killer carved those words into history then vanished into the fog. The case went cold. The city moved on. Until last night.

A high-security police vault has been breached. The thief ignored the cash and the narcotics but he took only one thing: the original Zodiac evidence files. Now a copycat calling himself The Disciple has scattered the 1969 artifacts across the city and marked innocent citizens for "collection," determined to finish what his Master started.

You're on the task force. Twelve locations, each tied to a Zodiac sign. No set order, only your instincts. And beware: some of them are traps designed to waste your precious time.

Crack the Zodiac's infamous ciphers, recover the stolen artifacts, and save the victims before the clock runs out. The ink is fresh, the knife is sharp, and the city is screaming for answers.

Start: Starting Point
Finish: Ending Point

Questions locals ask

Yes. The case unlocks the second you pay and there is no time slot to reserve. Buy at 7pm, walk to the starting point, and you'll be working the first clue within the half hour. If tonight falls through, it stays in your account.

Yes, the free Questo app on iOS or Android, about a 2-minute download. Buy on this page, open the app, and the case is waiting in your account. Grab it at home on Wi-Fi; the route itself runs fine on normal mobile data.

No. There's no guide, no group and no set time. It's a self-guided game: you unlock the case, walk the 2 km route on your own schedule, and everyone in your party gets clues on their own phone. Closer to an escape room than to a walking tour of Riverside.

Nothing is booked, so you simply play another evening. The case does not expire. If weather turns mid-game, pause it, get inside, and resume from the same point later. If you haven't started yet, take a full refund instead.

The Fellowship covers up to 5 phones for $23.99 ($4.80 each). Bigger groups usually share a phone between two, or add a second pass and run two teams on the same case. That's the better version, and the Riverside leaderboard settles it.

It's a whodunit, not a horror game: no jump scares, no gore, nothing chasing you. Kids usually spot the clues faster than the adults. Younger children can walk along, though the deduction will be over their heads.

Yes, and the case plays best after dark. Bring a charged phone; the route stays on public streets and squares, and it's roughly 2600 steps in total.

Yes, gift the case and the person you send it to picks their own evening, in Riverside or in any of the other cities it runs in. It doesn't expire, so it works for a birthday, a hen do, an anniversary or a team night out. They'll need the free Questo app to play.
