From a series of experimental prototypes arose the question of how to coordinate multiple players physically in the same space without breaking immersion. The goal was to create a quickly accessible, robustly synchronized game for events, offices, and parks with measurable enjoyment.

Filthy Fingers is a mobile AR game for up to eight players: short rounds, virtual fruits, collecting and stealing. We delivered a Unity client with Niantic Lightship integration, object occlusion, and peer-to-peer mesh synchronization, as well as physics-based interaction.

The process went from discovery through rapid prototyping to a stable build and a field test launch. The core was a host-side neural mesh from camera input, distributed to other devices via peer-to-peer messaging. Object occlusion and physics in Unity ensured credible interaction; the key insight was that clear visual feedback and simple synchronization have more impact than complex technology.

The most effective combination was a reliable host mesh, simple peer-to-peer communication, and visible physics: it made the gameplay mechanics immediately understandable and emotional. The central lesson is to make technology invisible so that game moments can be loud and shareable.
