## What is Abyssal Signal?

Descend into a Victorian deep-sea observatory where unknown creatures communicate through pulses.

  Arrange Invert, Delay, Reverse, Filter, Echo, and Amplify modules to reshape each signal until the received waveform matches the target. Every adjustment brings the mystery into focus, but one wrong move can send the message deeper into the abyss.

  Explore six chapters and 72 handcrafted logic levels. Find the optimal solution, earn three stars, restore the lost specimen archive, and uncover the creatures hidden in the depths.

  A new daily signal is available to solve offline, whenever you want a quiet, focused puzzle session.

  No account required. Play offline.
