The Experience

"You'll know the Tinguely when you see the water moving wrong," someone told me before I started — and they were right. The app opens at Barfüsserplatz, and the first riddle pulls you toward those nine machine-sculptures that splash and spin like they're arguing with gravity. It's not a tour in the traditional sense; there's no guide waiting, no group huddle, no fixed start time. You download the Explorial app, punch in your 6-digit code, and Basel's compact old town becomes a game board. The riddles move you from one landmark to the next, and the competition between people in your group — if you're traveling with others — keeps the pace honest.

The route climbs toward the Münster, where the Pfalz terrace opens over the Rhine like someone pulled back a curtain. On a clear day you can see Germany and France from there, and the app doesn't waste the view — it asks you something about what you're looking at. Then comes the Rathaus, that shocking sandstone-red town hall on the Marktplatz. The color stops you. The frescoed courtyard and golden tower are designed to make you stare, and the riddle knows it. Around two hours total, walking at your own pace, taking breaks whenever you want. There's no pressure to move faster or slower than feels right.

What makes this different from a standard walking tour is the flexibility. You're not locked into a group rhythm or a guide's schedule. Your phone is the only thing narrating, and you can pause, double back, or spend an extra ten minutes at any stop. The app works in 24 languages, so if you're traveling with people who speak different ones, everyone can play in their own language. After you finish, the leaderboard travels with you — if you're crossing the Rhine by ferry afterward, the scores are still there to compare.

Completely self-guided. The app sends you riddles and trivia that move you from one landmark to the next. No guide, no group, no fixed start time — just you, your phone, and the city.

What if I don't have a smartphone or it dies?

You need a fully charged smartphone with active mobile data to start. Bring your own device; the app won't work without it. Disable any VPN and avoid city Wi-Fi, as these can cause the app to disconnect.

Around 2 hours at a normal pace, but you set the speed. You can take breaks, linger at stops, or move faster — the app has no time pressure.

Can I do this with a large group?

Maximum 15 people per booking. If you have more, you'll need to make multiple bookings.

What languages is the app available in?

24 languages including English, French, German, Spanish, and Italian. You choose your language when you start the game in the app.

What if bad weather happens or I get sick?

You can reschedule for another day free of charge, rebook to a different city, or request a refund.

Is there a leaderboard or scoring system?

Yes. You compete within your group and can try to beat the city's high score. The leaderboard is visible throughout the tour.

Do I need to book a specific start time?

No. You start whenever you want. After booking, you receive a text and Viator message with your 6-digit game code. Download the app, enter the code, and begin.
