What is 100 Days At Sea?
100 Days At Sea is an open-world survival Roblox experience by Stranded Devs. The official game page describes a mission to the middle of the ocean where you uncover the mystery of the Bermuda Triangle, survive 100 in-game days, and get rich through exploration and base building.
100 Days At Sea Wiki is an unofficial fan wiki. We publish survival guides and island reference data cross-checked against the live Roblox description and community play reports.
Gameplay splits into day and night. During the day you harpoon resources, craft tools, and sail to islands. At night invading forces attack your raft — the loop repeats until you reach Day 100 or die trying.
- Platform: Roblox on PC and mobile
- Goal: survive 100 days and uncover the Bermuda Triangle mystery
- Core tools: Harpoon, workbench, raft structures, weapons
- 23 classes (Pearls unlock) · 8 island biomes · 6+ raid bosses
- Currencies: Pearls (classes), Coins and Doubloons (trading)
- Unofficial fan wiki — not affiliated with Stranded Devs or Roblox Corporation
Quick start
Five steps from spawn to your first safe night. Read the full beginner guide for class picks and boss order.
- Harpoon your first resources
Grab wood and scrap floating near your starter raft. Harpooning is the primary gather method on the official Roblox page.
- Build floor and essentials
Craft basic raft flooring, a workbench, and either a purifier or grill so hunger and thirst stay stable before sunset.
- Check codes and classes
Redeem any working codes for Coins or Pearls, then pick a starter class — Survivor is a common early pick for slower hunger drain.
- Sail to Starter Island
Visit the nearest island for stone, rope, and your first weapons before pushing into Jungle or Desert biomes.
- Survive the first night
Stock arrows or melee weapons and reinforce raft walls. Ghost pirate waves hit harder if you expand without defenses.

Common questions
What is 100 Days At Sea?
100 Days At Sea is an open-world survival Roblox experience by Stranded Devs. Survive 100 in-game days, uncover the Bermuda Triangle mystery, and expand your raft through harpoon gathering, crafting, and island exploration.
How do custom seeds work?
Seeds control island layout and sail distance between biomes. Community favorites cluster containers and Starter Island resources — see the best seeds guide for copy steps and reported codes.
How to revive a downed teammate?
Downed players need a medkit or defibrillator from a teammate. Medic class reduces revive time. Solo runs have limited self-revive options — the medkit revive guide covers both flows.
Which class should I unlock first?
Survivor is a popular starter for hunger and oxygen. Late game shifts toward Fire Mage, Pirate, or Ice Mage depending on island progress. See the tier list for spend order.
How do you play the survival loop?
Harpoon by day, craft weapons, explore islands, and defend against ghost pirates at night until Day 100. The beginner guide walks through the core loop, first-night defense, class picks, and early milestones on that path.
Is this the official wiki?
No. 100 Days At Sea Wiki is fan-maintained. Verify mechanics on the official Roblox page by Stranded Devs.
