Frequently asked

How do I play?

Drag anywhere to steer the probe and tap to send a sonar pulse. The walls light up for a moment where the pulse reaches them; walls you have seen stay as a faint outline. Reach the gold exit without touching a wall.

How do I get full signal (three bars)?

Each level has a pulse budget shown at the top right. Finish within it for full signal; a few more pulses still earn two bars.

I keep dying on a level. What helps?

Longer levels have checkpoint buoys: touch one and a crash sends you back to it. After a few tries you can watch an optional ad to see the way, and later to skip the level.

What is a streak freeze?

Clear the Daily Sonar Sweep every day to grow your streak. Finish all three daily goals to earn a freeze; a freeze is used automatically if you miss a day, so your streak survives. You can hold up to three.

Will I lose my progress if I change phones?

Progress is saved on your device. On Android it is included in your Google backup; on iPhone in your iCloud or device backup. Restore the backup on your new phone to keep your levels and streak.

How do I change my ad privacy choices?

Open Settings in the game (the gear on the home screen) and tap Privacy choices. This option appears in regions where consent is required, such as the EU and UK. You can also reset your advertising ID in your phone's settings.

I bought Remove ads. How do I restore it?

Open Settings and tap Restore purchases, signed in with the same Google or Apple account you used to buy it.

How do I delete my data?

All game data lives on your phone; uninstalling the app deletes it. See the privacy policy for what Google AdMob receives and how to control it.
