Desert Island Survival: Can You Last 72 Hours Until Rescue?
▶ PLAY FREE NOWNo download · Phone or PC · 3–5 minutes per runDesert Island: 72 Hours is a free, choice-based desert island survival game you play right in your browser. A company reward cruise sinks in the sea south of Jeju, Korea, and Seongsu Team 3 has spent three days in a life raft. One afternoon in May, the raft is pushed past white breaking surf and a coral reef toward a nameless island. All you have is a handheld VHF radio at 38% battery and half a liter of water. And the cruise's first officer, who says, "I'm the professional. Just follow me." The island, ship, company and characters are all fictional.
How the game plays
The right choices come from the Korea Coast Guard, the Ministry of Food and Drug Safety, the US Coast Guard (USCG), NOAA and common survival-manual rules; the wrong ones are mistakes real castaways actually make.
- 30 seconds before the surf: Tighten your life jacket? Tie the radio into a dry bag? Jump off first and swim?
- 25 seconds in the waves: Time doesn't stop after the raft flips. A radio drifting away, a new hire flailing, a rip current pulling you out to sea, a razor-sharp coral reef — if you can't choose within seconds, you get hurt.
- 4.5 hours until sunset: A shade canopy, hauling the raft above the high-tide line, the emergency pack, an SOS, a signal-fire pile, a MAYDAY on the radio. While your throat burns, seawater and the mussels on the rocks beckon.
- Holding out for 72 hours: As day and night turn, event cards appear. Rain showers, a spring in the rocks, search planes, a storm surge, a fishing boat's lights on the night sea, and things that suddenly leap out of the dark (you can turn jump scares down in settings).
- The helicopter: How do you signal it, who goes first, and how do you board?
The radio: battery is life
Turn on the radio with the 📻 button at the bottom right of the screen. While it's on, the battery drains and time keeps passing. Turn the dial to find Channel 16 (distress & calling), 06 (ship-to-ship), 69 (the scattered group), and a mysterious static channel. If you're off-channel or the signal is weak, transmissions break up into ▒. When and how you send your MAYDAY changes when the rescue helicopter arrives.
The villain: First Officer Yoon Tae-ho
A torn white uniform, a calm voice. At first he seems like a reliable leader, but he collects the lighters and cans to "manage" them, says the location beacon (EPIRB) went down with the ship, and tries to lead people to the far side of the island. Gather clues and you can expose his lies; his fate appears on the results screen. Jay, the YouTuber from the previous episode, also made it onto the island.
Story, random situations and perks
Story mode plays the landing scenario exactly: May, 3 p.m. In Random situation mode, the time left until the surf, whether the bay has rip currents, the night a storm surge hits, when the first shower comes, and whether there's a spring all change every run. Each run also gives you one perk.

24 result types
There are 12 types for those rescued and 12 for those who died on the island. Compare with others who got the same type, and ask your friends, "What did you get?"
Island InstructorShade, water, signals, then food. 72 hours, straight by the manual.
Villain ExposerYou finally exposed the lies behind the uniform. The dead EPIRB blinked back to life.
Keeper of the Signal FireAn SOS and a pillar of smoke. The sky found us first.
Rain CollectorYou didn't miss a five-minute shower. You never touched seawater.
Beach ERCoral cuts and heat exhaustion — you saved people one by one.
Holder of the BeachWhen he said "Follow me," you didn't. You held the beach where you first landed.
Last-1% Radio OperatorYou nursed the dying radio to the very end.
Guardian of the New HireIn the surf, you didn't jump in — you threw a cushion. Jiwoo lived.
Sage of the ShadeYou didn't move at midday. A drop of sweat is a sip of water.
Bone-Dry SurvivorYou lived. Nearly dried out.
The cool-headed survivorGot through three days without a major mistake.
The lucky-break survivorMistakes everywhere, but the helicopter came. Will it come next time?
Swept Away by the SurfThe beach was 30 m away. The breaking surf showed no mercy to a body that had held on for three days.
Fought the Rip CurrentYou swam for the beach to the very end. Twenty strokes sideways would have done it.
Stood on the ReefWhere you stepped was a blade.
A Sip of SeawaterJust a few gulps. The thirst came back twice as bad.
A Plate of Spring ShellfishYou thought cooking would make it safe. The toxin doesn't burn off.
Midday LaborerYou thought a cloudy day would be fine. When the sweating stopped, that was the warning.
Lookout on the PointYou wanted to spot a ship first. The rock slipped first.
Went Into the DarkBeyond the brush, beyond the rocks. The island at night was full of unknowns.
Followed the Villain"Just follow me." You followed him to the end.
A Night Below the High-Tide LineYou thought the raft would be fine there. The stormy sea crossed the seaweed line.
The Last Drop of WaterThe water ran out in a day. No rainwater, no boiled spring water.
Ran Into the SeaYou saw a light, a helicopter, a voice. The sea didn't tell you to wait.8 tips for surviving
- Before the surf, tighten your life jacket, sit low on the raft floor and hold the lifeline.
- If a rip current pulls you out, swim sideways, parallel to the shore.
- Don't jump in after someone drowning; throw something that floats.
- Shade → water → signals → food, in that order. Move less at midday.
- Don't drink even one sip of seawater. Collect rain showers and boil spring water.
- Don't eat spring clams or mussels. Cooking doesn't remove the toxin.
- Stay together on the beach where you first landed. There's no guarantee "Follow me" is the right answer.
- When the helicopter comes, wave both arms in the open and wait for the rescuer's instructions.

FAQ
Is the desert island game free?
Yes. It's a completely free browser game with no payments and no download. It works on phones, tablets and PCs.
How long does one run take?
Usually 3–5 minutes. The 30 seconds before the surf and 25 seconds in the waves play out in real time; the 72 hours pass quickly.
Do I really have to last the full 72 hours?
No. The more precisely you report your position — with a radio MAYDAY, signals to search planes or the location beacon (EPIRB) — the sooner the helicopter comes. With no signals at all, a search helicopter passes by at hour 72.
Are there jump scares?
There are a few scenes at night where something suddenly leaps out, with loud sounds and vibration. You can switch to "Fewer jump scares" in the settings on the title screen.
Is it a real island or ship?
No. The island, cruise ship, company and characters are all fictional. Only the safety rules follow real official guidance.
Are there other episodes?
The castaway series is one continuing story: the West Sea mudflats, Seoraksan in winter, adrift in a life raft, Desert Island: 72 Hours, and a crash in the Amazon. The same Seongsu Team 3 runs into disaster on every reward trip.
