Coddy

Numinam designed and built Coddy, a mobile escape game app for iOS and Android that turns a real city into the game board for families, corporate teams and school groups. No venue to book, no host to wait for: you download the app, gather your team, and the streets around you become a series of puzzles to solve. I designed the experience to feel effortless, whether it's a family on a Sunday, a company offsite, or a school class on a field trip.

Designing a location-based escape game for the open city

Most escape games live inside a single room. I wanted Coddy to live in the open city, which is far harder to design for. Players keep one eye on their phone and one eye on the street, so the app has to guide them without turning the adventure into just another screen game.

That tension shaped every decision. A traditional escape room controls everything: the lighting, the props, the order in which clues appear. An open city controls none of that, so instead of fighting the environment the design leans on it. The streets, the landmarks and the details around the players become part of the puzzle, while the phone steps back to a supporting role, pointing people toward what is already in front of them rather than asking them to stare at a screen.

On top of that, the same product had to work for three audiences that could not be more different: children and parents, corporate teams, and school groups. One app, three very different expectations.

Each of those groups comes with its own rhythm and its own expectations of difficulty, length and atmosphere. Designing a single experience that bends to all three, without splitting into three separate apps, meant treating tone and pacing as things the game adapts rather than things hard-coded into it.

Building a self-serve mobile escape game for families, teams and schools

The app was built around a few firm principles:

• A self contained experience: activate a code, start playing immediately, with no facilitator and no setup;

• Puzzles anchored to real places, so the city itself holds the clues and the phone simply connects them;

• One product, three tones: difficulty, length and atmosphere adapt to families, companies or schools without fragmenting the app;

• Team play designed for groups of up to six, so it stays a shared moment instead of everyone staring at separate phones;

• Built in help, with a chat and an emergency option, so a stuck team is never truly stuck and the game keeps its momentum.

Each of these principles answers a practical problem. Removing the facilitator means the experience has to carry itself, so the only thing standing between a team and the start of the game is a code, which keeps the barrier to playing as low as possible. Anchoring puzzles to real places keeps players looking outward at the city, and capping team play at six keeps it a shared moment rather than a row of people each absorbed in their own screen. The built in chat and emergency option are there so that a moment of being stuck never turns into the game grinding to a halt.

A live iOS and Android escape game app, played anywhere in the city

Coddy is live on iOS and Android as a genuine self serve escape game. There's no room to rent and no host to schedule: the adventure starts the moment a team is ready to play. The same app fits a birthday afternoon, a team building session and a class outing equally well, which is rare for a single product.

Being live on both iOS and Android matters more than it sounds. A team rarely all carries the same kind of phone, so supporting both platforms is what lets a group gather and start together without anyone being left out, and because the game is self serve there is nothing to coordinate beyond the people themselves.

The result proves a simple idea: an escape game doesn't need four walls. It just needs a city and a phone.

Frequently asked questions

How does a city-wide escape game work?

Instead of locking players in a single room, Coddy turns the streets around you into the game board. The puzzles are anchored to real places in the city, so the clues are in the world itself and the app simply connects them. You keep one eye on your phone and one eye on the street, solving puzzles as you move through the city.

Do I need to book a venue or a host to play?

No. Coddy is a self serve escape game with no room to rent and no host to schedule. You activate a code and start playing immediately, with no facilitator and no setup. The adventure starts the moment your team is ready, so there is nothing to coordinate beyond gathering the people who want to play.

Can Coddy be used for corporate team building?

Yes. The same app fits a corporate team building session as well as a family afternoon or a school outing. Coddy is one product with three tones: difficulty, length and atmosphere adapt to families, companies or schools without fragmenting the app, and team play is designed for groups of up to six so it stays a shared moment.

What happens if my team gets stuck on a puzzle?

Help is built into the app. There is a chat and an emergency option so a stuck team is never truly stuck and the game keeps its momentum, letting you get a nudge and carry on rather than losing the thread of the adventure.
