Lost Treasures Unblocked

Pilot a little submarine across a 3D seabed and dive down to scoop up every hidden gold coin.

now playing: Lost Treasures

Not every game needs a timer or a health bar. Lost Treasures unblocked is a slow, peaceful search where you cruise a small round submarine over shallow blue water and look for gold on the sand below.

Markus Fisch made it for the js13k game jam, and every model you see, from the sub to the hills on the seabed, is generated by code when the page loads. It runs in WebGL, so you need a browser that supports it.

How to play Lost Treasures

Text along the top of the screen shows the number of coins to find. The count changes each game, somewhere between five and nine. Drive around near the surface and watch the sand for a small glint of gold.

When you find one, steer over it and hold dive. Your sub sinks toward the floor in a stream of bubbles, and it floats back up when you let go. You only collect a coin when you are right on top of it, so line up before you go down.

The counter ticks down with each coin. After the last one, a link lets you start a fresh round with a new seabed and new hiding spots. Nothing can hurt you, so take your time.

Tips

  • Search high, dive low. You can see farther from near the surface. Only sink once a coin is close by.
  • Brake before diving. The sub keeps drifting after you let go of forward, so tap reverse to stop right above the target.
  • Use your shadow. The dark spot under the sub shows where you will land. Put it on the coin and then dive.
  • Mind the hills. You can't sink lower than a little above the ground, so coins in dips are easier to reach from above flat sand.
  • Turn back at the red warning. It means you left the search area, and no coins are hidden out there.

Lost Treasures questions

I passed over a coin. Why didn't it count?

You have to be very close in every direction, including depth. Coins sit near the sea floor, so hold dive until the sub is almost touching one.

Is the seabed different each time?

Yes. Each new round builds a fresh set of hills and puts the coins in new places, and the number of coins changes too.

Can I play on a phone?

Yes. Touch screens show two round controls: one for steering and one for diving. Hold the device sideways for the widest view.
