AR Bottle Activation

The challenge

Jana, one of Croatia's biggest spring-water brands, wanted its bottles to do more than sit on a shelf. The brief was simple. Turn the packaging itself into a promotion people could play, right from their phone, with nothing to download.

What I built

A WebAR game you reach by scanning a QR code printed on the bottle. Scan it and the experience opens in the phone's browser, no app install, dropping you into an augmented world where the goal is to find and collect five bottles that spawn randomly around you.

I programmed the game in JavaScript on 8th Wall (A-Frame and three.js for the AR) and built the interface in HTML and CSS, delivered as part of the Brojka team. It's a different stack from my Unity work, which is the point. The approach travels: pick the right technology for the goal, and make it run in whatever the customer already has in their hand.

The result

The activation ran for about six months and engaged thousands of users, with no app to install.

Why it worked

No friction. The QR code sat on something already in the customer's hand, and the game opened in the browser. No app store, no download, just scan and play.

The packaging became the entry point, so the product itself drove the engagement. The bottle wasn't advertising the game. The bottle was the game.

And the goal was simple enough to pick up in seconds. Find the five bottles, and you're in. No tutorial, no instructions, no learning curve standing between the customer and the brand.
