100 Days At Sea Roblox -- Guides, Codes & Tips (2026)

100 Days At Sea is the open-world ocean survival hit from Stranded Devs, sitting at a 96.7% rating and more than 45 million visits since launch. This is the central hub for every guide, code list, and comparison we've published on it.

The pitch is simple and brutal. You wash up with nothing and have to survive 100 in-game days while uncovering the mystery of the Bermuda Triangle. Most new players sink within their first dozen days because they ignore food, water, and shelter in favor of exploring too soon.

The core loop centers on harpooning resources, building a raft and then a proper base, and pushing outward to new islands. Each island holds better loot, tougher threats, and another clue toward what's really happening out on the water. You'll find weapons, craft tools, and defend your base from whatever comes calling at night.

Since the November 14, 2025 launch, the game has held a steady spot in Roblox's survival category. The 96.7% approval rating comes from over 1,373 votes, which is unusually high for a survival title where one bad death can wipe hours of progress.

Why Play 100 Days At Sea?

The hook that sets 100 Days At Sea apart is the deadline. You're not just surviving forever in an open sandbox -- you're racing a 100-day clock toward an actual ending tied to the Bermuda Triangle mystery. That structure gives every harpoon throw and every plank of wood a clear purpose.

Progression feels earned rather than handed out. Early on you're harpooning fish and scrap just to eat, then you graduate to a raft, a wooden base, and eventually fortified walls that can take a night raid. Each island you reach raises the stakes with stronger enemies and better gear, so the difficulty curve keeps pace with your growing kit.

The community stays active because Stranded Devs ship regular content. New islands, weapons, and companions have kept the 650-plus concurrent player base coming back, and the 96.7% rating reflects how rarely updates break the survival balance. If you like games where preparation beats reflexes, this one rewards the planners.

Where the game really clicks is the resource economy. Wood, stone, scrap metal, and food each have their own gathering loop, and you'll spend your first week balancing all four instead of chasing one. Harpooning is the backbone of it -- you aim, time the throw, and reel in fish, floating crates, and sharks that fight back harder the deeper you swim.

Base placement matters more than new players expect. Build too close to the shoreline and night raids hit you from the water; build too far inland and your raft trips eat into precious daylight. Our guide walks through the layout we settled on after several failed runs, including which walls to prioritize before day 20.
