Two simple calls
Learn the difference between short and long signals, then repeat them in sequence.
Growing challenge
Every successful relay adds another step and asks you to stay focused a little longer.
Fogbound atmosphere
A lighthouse, water, signal beams, and changing feedback create a distinctive harbor mood.
Double Fog
Special rounds change the rhythm and ask you to rely on the full visual language of the signal.
Personal best
Track your longest completed sequence and return to improve it.
Clear feedback
Know when a relay matched, when a call was wrong, or when the response window closed.
