About Sonar
An underwater cave in total darkness. Press ping and a pulse spreads out from your submarine, lighting up the walls, pearls and the creatures around you for a moment before it all fades. Collect pearls for points and air, find the gate to the next cave, and dive as deep as you can. The catch: every ping wakes up the creatures, and they come for the sound.
How to play
- Desktop: swim with WASD or the arrow keys (or hold the mouse), Space to ping.
- Phone: hold to swim towards your finger, tap or use the Ping button to ping.
- Creatures cost you one of three hull segments. Running out of air also ends the dive.
Tips
- Ping at a steady rhythm, not in a panic.
- Keep moving after a ping. The creatures head for where you were.
- Pearls give back air, so don't leave easy ones behind.
- When the air warning turns red, head for the nearest gate or pearl.
FAQ
Is it free? Do I need an account? It's free, paid for by ads. No account: you only type a name if you want to post a score.
Does it work on a phone? Yes. Hold to swim, tap to ping. It's best with headphones.
