Can you rob the phone beside you?

Yes. Sonic Heist is a heist game played over ultrasound.

What happens in a heist?

Find who is in earshot

Your phone pings the room and everyone on patrol answers. You never see what they hold.

Sneak to their seat

Their phone signs a ticket. You take 5 to 25% of their stake and post a bond of 20% of the loot.

10 seconds to vanish

Then they find out. Stay out of range for 60 seconds and the loot is yours.

Or get hunted

Your victim pulses a radar and closes in. If they catch you, they win your bond.

What if someone robs you?

Your phone sounds the alarm. You get one minute to walk them down.

The second they get away
Catch them: your stake back, plus their bond

Who do you play as?

Pick one. It follows you down the page and takes over every phone here.

Every theft and save levels your thief up.
