Play Beacon Watch online
Beacon Watch is an original lighthouse-guidance arcade game: aim a rotating beam to steer night boats past rocky water into the harbor.
Boats outside the beam drift straight ahead and will wreck on rocks they cannot see. A lit boat turns toward the harbor and steers around rocks.
Ten guided boats win the game; three wrecks or 150 seconds on the clock end the run.
How to control Beacon Watch
- Aim beam: mouse move or touch drag
- Rotate beam: Left / Right arrow keys
- R: restart, M: mute

Tips for a better run
Track the boat nearest a rock first — one sweep of the beam can save it before impact.
A lit boat keeps turning toward the harbor, but it only steers while it stays inside the beam, so follow it, don't just flash it.
Chain guides within 4 seconds of each other for up to +100 bonus points per boat.
Boats spawn from the top, bottom, and left edges — sweep the whole sea, not just the harbor mouth.
Frequently asked questions
How do I aim the beam?
Move the mouse or drag on touch to aim the lighthouse beam. Arrow keys rotate it too. Boats only steer toward the harbor while they are inside the beam.
How do I score?
A boat counts as guided when it sails into the glowing harbor mouth on the right edge. Guiding boats quickly in a row builds a chain bonus.
What happens if a boat hits a rock?
Boats outside the beam sail straight and cannot see the rocks. A boat that hits a rock is lost; three wrecks end the run.
How do I win?
Guide 10 boats into the harbor within 150 seconds to win. Running out of time or losing 3 boats ends the run.
