Play Pocket Sonar Online
You ping sonar over a murky grid, heart racing as beeps speed up near treasure—until a shark icon ruins your day. Those pixel crabs attack like they’ve got a personal grudge.

Ever wanted to play Battleship but as a scruffy undersea explorer with a Game Boy? That’s Pocket Sonar in a nutshell. You’re staring at this tiny grid, listening for sonar pings that get faster when you’re near treasure—and then there’s the panic when a shark icon suddenly blips into view. The pixel art’s got that perfect chunky-Game-Boy-charm, all teal and murky blues.
At first it feels almost too simple, but then you realize you’re leaning closer to the screen, holding your breath as the beeps speed up over some weird coral formation. Found a Roman coin? A broken pocket watch? No idea what half this junk is, but I kept diving just to see the next thing. Also, the crabs are weirdly aggressive for pixel crustaceans.
It’s the kind of game you play for "five minutes" and suddenly it’s been half an hour. Perfect for bus rides or pretending to be Jacques Cousteau in your pajamas.
