What is Lost Treasures?
Lost Treasures is a relaxing 3D exploration game. You steer a small submarine across a randomly built seabed, spot gold coins resting on the sand and dive down to collect them. Each round hides between five and nine coins, and there is no timer or danger, so you finish whenever the last one is found.

Lost Treasures is the kind of game you play to slow down. You drive a chubby submarine with a whirring propeller through clear blue water, and somewhere on the sandy bottom a few gold coins are waiting. There are no sharks, no air gauge and no countdown, only shadows on the sand and bubbles trailing behind you. Markus Fisch built it for js13k 2017, when the contest theme was “lost”, and every model is generated by code as the page loads. It plays unblocked on desktop and touch screens alike.
A Round in Practice
A message at the top says how many coins are hidden this time. The total varies between five and nine. The camera sits behind the sub, and the far seabed fades into a blue haze, so you will need to cruise around and keep an eye out for a tiny orange sparkle.
When you see one, turn until it is straight ahead and hold dive. The sub sinks, bubbling as it goes. Release and it bobs back up toward the surface. You only collect a coin when you are nearly touching it, so precision matters more than speed.
The message updates after every find. When the final coin is in, a short note appears with a link to play again, and a brand new seabed is built.

Search Like a Pro
Searching a whole sea floor sounds slow, but a little method helps a lot.
Cruise high, dive low. The view from near the surface reaches much farther, so do your scouting up there and only sink when a coin is close.
Brake before you sink. The sub keeps gliding for a moment after you release forward. A quick tap of reverse stops you so you drop straight down onto the coin instead of overshooting.
Point, then push. You travel faster in a straight line than while turning, so line up first and then hold forward.
Use the pyramids as landmarks. The two old pyramids help you remember which parts of the map you have already covered.
Line up the shadow. The sub’s shadow on the sand shows exactly where you are. Park the shadow on top of the coin and dive.
If red text warns that you have left the dive area, turn around. No coins are ever placed outside it.
Why It Feels Different
Most games on FreezeNova push you to go faster. This one rewards patience and a good eye. It is a nice wind-down after something hectic, and it is simple enough for kids. If you enjoy calm exploration, try the robot puzzle Humwin & Darbold, or browse our casual games for more low-pressure picks.
Lost Treasures: questions players ask
Is Lost Treasures good for young kids?
Very. Nothing can hurt the submarine, there is no clock and no way to lose. Children can cruise around at their own pace, and the only goal is spotting shiny coins on the sand.
I am right above a coin. Why won't it count?
Coins sit just over the sea floor, so being above one is not enough. Hold the dive control until the sub sinks low and almost touches the coin. Also check that a hill is not stopping your descent.
Can I play Lost Treasures on my phone?
Yes. Touch screens get a steering stick on the right and a dive button on the left. Turn the phone sideways for the best view. The game needs a browser with WebGL support.
Does the map change between rounds?
Yes. Every new round builds a different seabed with new hills, and the coins are placed in new spots. The number of coins changes too, anywhere from five to nine.
