About the game:
One Boat. Eight Paddles. Total Chaos.

Sync or Sink is a physics-based, local multiplayer party game where coordination is the only way to survive. Forget traditional controllers—your smartphone is your oar. Grab your friends, connect your devices, and prepare to find your rhythm or sink into the abyss.

The Phone is the Controller
Using a simple browser-based connection, Sync or Sink turns your mobile device’s internal sensors into a tactile interface.

Physical Paddling: Physically tilt, flick, and thrust your phone to stroke the water.

No Apps Required: Players join the game instantly via a QR code. If they have a phone, they’re in the crew.

High-Stakes Coordination
This isn't just a race; it's a test of collective physics.

8-Player Local Multiplayer: Built to support anywhere from 2 to 8 players on a single screen. The more people you add, the more chaotic the coordination becomes.

Dynamic Water Physics: Every paddle stroke translates into real-time force. If the left side of the boat rows harder than the right, you’ll spin. If everyone leans at once, you’ll capsize.

Communicate to Survive: Navigate through treacherous currents, whirlpools, and obstacles that require split-second teamwork and constant communication.

Easy to Learn, Impossible to Master
Designed for the ultimate "couch co-op" experience, Sync or Sink bridges the gap between digital gaming and physical movement. Whether you’re a veteran gamer or someone who has never picked up a controller, the intuitive motion controls mean anyone can start rowing in seconds.

Can your crew find the rhythm? Or will you be the reason everyone sinks?
