The city game

Turn your city into a game you play on foot.

Ciudadex turns any city's landmarks into a photographic treasure hunt. Visitors walk further, discover corners off the beaten track, and open the app again the next day.

For travelers who want more than a guidebook — and for the town halls that want to show what they have.

The loop

A clue. A walk. A capture.

The same gesture, again and again. Every captured place unlocks its story and earns points by rarity.

Get a clue

The app offers the nearest unsolved place. The clue is a single sentence written by you — or a photo to recognize.

Walk to it

No navigation map, no arrow. The clue and curiosity are enough to get there.

Take its photo

A well-framed photo that matches the reference. No framing aids — that's part of the game.

Capture it

Success: the place joins the collection. Points by rarity, revealed only now.

Unlock its story

Your guide, your archive photos, your local tip. The reward for every capture.

Come back for more

An incomplete collection pulls the player back. Tomorrow, another clue, another neighborhood.

The loop never ends — back to 01

Your material, on stage

The municipal archive wasn't made for a drawer.

Every town hall keeps thousands of photographs that were never scanned or shown. In Ciudadex, those images become the reward: a gallery with its year, caption, and credit, unlocked by the player right after capturing the place.

Archive gallery

As many historical photographs as you want per place, with year, caption, and credit.

Your voice

You write the clues and the guides. They are the most valuable content in the game.

Your seal

A discreet credit in the city's notebook: "This Ciudadex city is powered by…".

Questions

What town halls usually ask us.

Who writes the content?

You do, with our editorial help. The clues and guides, in one or two languages, are the most valuable content — and nobody knows the city better than your team. We give you the template and the voice.

How many places does it take to start?

We start with 8 to 25 places. No need to cover the whole city: the proximity mechanic reveals clues little by little, so the notebook never overwhelms — even with 100 places.

Where do the archive photos come from?

From your municipal archive. We digitize and prepare them; you provide the image, the caption, and the credit.

Is it free for visitors?

Yes. Players pay nothing and need no account to start. They only create one to save their collection and appear on the leaderboard.

How does the town hall appear?

Through a discreet credit at the foot of the city's notebook — the screen returning players see the most. Three flavors: town hall, tourist office, or a Ciudadex offer.

Do you collect visitor data?

Only what the game needs, plus a voluntary email to announce when the city grows. That mailing list is also your proof of demand.

A personal note

Why we're building Ciudadex.

Cities keep treasures nobody looks at: an Art Nouveau façade two streets from the main square, an archive full of photographs that have never been scanned. Tourist guides list them; nobody visits.

Ciudadex isn't a guide. It's a reason to walk there. And when the visitor arrives and captures the place, we give them back the city's story — the good one, the one that was sleeping in a drawer.

If you represent a town hall or a tourist office and want to see your city played end to end, let's talk. The demo takes fifteen minutes and we run it with you.
