100 Days At Sea Wiki

Overview

Stranded Devs' 100 Days At Sea is built around a single premise: survive 100 days in the Bermuda Triangle by turning a handful of floating planks into a mobile fortress. The official Roblox description frames the experience around harpoon gathering, raft construction, island exploration, and weapon-based defense against raiders and bosses.

The core gameplay loop follows four pillars: harpoon drifting resources from the water, building a raft base with structures and defenses, sailing to mysterious islands for better loot, and preparing weapons to fight ghost pirates, sharks, and biome bosses. Daytime is for gathering and expansion; nighttime triggers raids that test your walls, food stock, and combat readiness.

As of the June 27, 2026 update, the game has crossed 102.6 million visits and maintains an active player base above 31,000 concurrent users.

Core Gameplay Loop

Every run alternates between day and night phases on a mobile raft:

The four official gameplay pillars are:

• Harpoon — Hook drifting crates, planks, and debris from the water.
• Build — Expand raft floors, add storage, and ring the perimeter with walls.
• Explore — Dock at islands for chest loot, boss materials, and rare recipes.
• Fight — Use melee, gun, and magic weapons against raiders and bosses.

Currencies

Three currencies drive progression:

Pearls are earned from island chests, daily quests, boss drops, and active promo codes. Because they persist, spending them on the right class unlock has a bigger long-term impact than any single-run purchase.

Classes Overview

The game ships with 23 reported classes unlocked via Pearls. Each class provides a starter tool and one or more passive buffs that shape how you survive early days and approach islands.

Class roles split roughly into:

• Survival starters — Sailor, Survivor, Medic
• Combat specialists — Swordsman, Cowboy, Soldier, Knight, Sharpshooter, Pirate, Fire Mage
• Economy accelerators — Merchant, Millionaire, Treasure Hunter
• Utility niches — Camper, Adventurer, Olympian, Zookeeper, Ancient Squid

Full Pearl costs, starter tools, and a role-first tier ranking are available on the Classes page. Exact values should always be confirmed in the lobby Classes menu after patches.

Companions Overview

Companions are tame allies that provide passive buffs such as extra health, faster sprinting, hunger reduction, or automated material gathering. They are obtained by opening companion chests purchased with Pearls.

Four companion chest groups are reported in the current build:

See the Companions page for the full drop table and build suggestions. Drop percentages are community-reported and should be treated as approximate until confirmed in-game.

Badges and Milestones

The game tracks progress through 49 public Roblox badges. These can be grouped into milestone categories:

Badges function as natural checkpoints. New players should treat Day 1, Day 5, and Day 10 survival as the first concrete goals, then layer in crafting and economy badges.

Islands and Bosses

Eight core biomes scale from safe starter zones to endgame areas:

The Volcano route is one of the most reported endgame paths: defeat three Fire Golems, throw their bodies into the volcano caldera to summon the Lord of Lava, then open the Magma Chest for a chance at the Magma Staff.
