Couch Convoy
In progressA co-op trucking party game. The game runs on a laptop or TV, friends join by QR code, and each phone shows a different role (driver, navigator, mechanic, spotter).
- Stack
- WebRTC, Phone motion sensors
- What it proves
- Real-time networking over WebRTC, phone motion sensors, and host-authoritative game state.

Four phones, four different jobs
Phones-as-controllers platforms already exist, so Couch Convoy does not lead with that. It leads with asymmetric co-op: every phone shows a different role, and the truck only gets anywhere if the four players talk to each other.
- Driver. Steers by tilting the phone. The preview above follows your pointer instead.
- Navigator. Sees the route the driver cannot.
- Mechanic. Keeps the truck running.
- Spotter. Watches for what is coming.
The game itself runs on a laptop or TV. Friends join by scanning a QR code; nobody installs anything.
How it is built
- WebRTC carries input from each phone to the host with as little delay as the network allows.
- Phone motion sensors drive the steering. On iPhone, motion access needs a tap and a permission prompt, so the game asks only when the driver chooses tilt steering.
- Host-authoritative state. The laptop or TV owns the game state. Phones send inputs and receive what to show, so two phones can never disagree about where the truck is.
