Route a radio signal across a grid before it fades to nothing.

Play it → · best on a phone, held sideways

Squelch is a puzzle game about spending power. A transmitter fires a signal across a grid and every tile it crosses costs it strength. You lay out reflectors, amplifiers, splitters and filters to steer that signal into a receiver while it still has something left. Run it and the beam crawls out tile by tile, cooling from cyan to red as the meter drains, and leaves the exact reading behind on every square it touched.

It is a phone game first.
