Days At Sea

100 Days At Sea is an open-world ocean survival game on Roblox by the verified developer group Stranded Devs where players are marooned in the middle of the ocean and must survive 100 in-game days to uncover the mystery of the Bermuda Triangle. Launched in November 2025, it crossed 28 million visits in under six months and earned a 97.4% approval rating - one of the highest on the platform - making it one of the fastest-growing survival games in Roblox's recent history.

The core mission is clear: survive 100 days at sea and get rich. Every mechanic feeds that goal. Players gather driftwood, scrap metal, and other floating resources by hand or by hooking them from a distance with the Harpoon tool. Those materials go into building a Raft - the player's floating base - and the structures placed on it for storage, shelter, and defense. The open sea is never empty: mysterious islands hold loot, weapons, and story clues tied to the Bermuda Triangle narrative. The full survival framework covers:

• 🗺️ Raft building - construct and expand a floating base platform using gathered materials; add structures for storage, shelter, and defense against threats
• ⚔️ Resource gathering - collect driftwood and scrap from the ocean surface; use the Harpoon to hook distant floating items without leaving your raft
• 💎 Island exploration - sail to scattered mysterious islands to loot supplies and uncover clues about the Bermuda Triangle mystery
• 🏆 Day counter - survive to Day 100 to trigger the rescue win state and "get rich"; milestone badges track every 10-day interval from Day 5 through Day 90
• 🏠 Rigging progression - a 9-tier crafting and building skill ladder that tracks mastery of the construction and raft mechanics
• 💰 Wealth system - in-game money tracked across three badge tiers (Money Bags, Plunderer, Money Marauder) accumulated through successful ocean play

Multiplayer supports up to 27 players per server, with badges recognizing crew sizes from solo play (All Alone) through full crews (And they were crewmates). A cooking mechanic (We Cookin badge) confirms a food and hunger system alongside the building loop. The game supports PC, mobile, and console.

100 Days At Sea is among the best-rated survival games on Roblox, distinguished by its Bermuda Triangle narrative hook and deep raft-building system that draws comparisons to the PC game Raft but built for the social Roblox environment.
