Signal//Lock is an atmospheric arcade puzzle that lives entirely in your browser. The screen is a slow, green radar sweep. Each rotation surfaces transient signals — packets, biological pings, missile vectors, morse pulses — that bloom for a moment and then fade. Your job is to lock them on before they disappear.
It's deliberately short-form. A run lasts a few minutes. There's no account, no install, no microtransactions — just a radar, your reflexes, and an escalating queue of signal types to learn.
The vibe
Cyberpunk command-deck. Dark CRT scanlines, soft neon green, low rumble. Inspired by the cinematic radar sequences of Hunt for Red October and Crimson Tide, the cassette-tape interface of Alien: Isolation, and the tactile signal puzzles of Keep Talking and Nobody Explodes.
How it differs
- Plays instantly in any modern browser — desktop, tablet, or phone.
- Nine distinct stage mechanics, from rocket vectors to letter echoes to bio-locks.
- Combo system rewards rapid streaks: trail streaks at low combo, salvo strikes (screen shake + shockwave) at 3+.
- No paywalls, no logins, no ads. The whole game is free.
Who it's for
Players who like minimalist arcade games, ambient puzzle experiences, or anyone looking for a quick focused break that isn't another match-three. If Geometry Wars, Audiosurf, or Tetris Effectfit your palette, Signal//Lock will too.
