Places the badges name

Magellan requires every island in a single session, so the ocean is a set of islands rather than one destination. The badges also name the Ice Biome, a volcano, a mothership, alien ships, rival rigs, and a Corruption Dungeon. Glorbus is named only as someone you must feed. His island is not in the badge text.

Community route, after the raft is fed

Beginner guides published in October 2026, drawing on July build notes, use this visit order:

  • Go earlier: Fisherman Island for an NPC, chests, and a possible Dinghy. Trade spare food. Mini islands for small chests while you are already sailing.
  • Wait: Survivor Islands with Ghost Pirate waves, towers, fortresses, and strongholds.
  • Alien Island after you can clear the alien raid those guides place around night 6 or 7.

Map Radar is the tool they tell you to craft before those longer sails. Radio is the later tool they associate with finding survivors. Neither cost is pinned tightly enough to repeat as a recipe here.

Night rules that keep a route alive

Stay on the raft with the Bonfire lit. Community guides name the Angler Fish as the threat when you swim at night or let the fire die, and they say a Flare Gun can pull it. Sharks are a water fight they tell you to leave rather than win. Ghost raids are confirmed by the They'll be back! badge. Corpses from those raids are the reported input for Green Gum at the crafting machine.

Seeds

Players search for a best seed and a custom seed box. No verified seed field, repeated route, or official seed list was found for place 70411440483149. Do not download a seed generator or type a comment code into anything except a menu you can see in Roblox. Start the run, hook resources, and use Map Radar when you have it.

If a later update adds a seed box, a useful note needs the exact string, the menu name, the first landmark, and a second run that matches. A clip title is not that note.

FAQ

Frequently Asked Questions

What is the goal in 100 Days at Sea?

Survive 100 in-game days in the Bermuda Triangle. You hook resources with a harpoon, build a raft, visit islands, and fight the threats named on the official badges.

Is this the same game as 99 Nights in the Forest?

No. 100 Days at Sea is made by Stranded Devs. Its description credits 99 Nights in the Forest, by Grandma's Favorite Games, as the inspiration. Codes from one game do not redeem in the other.

Which codes are worth trying?

Join a server, open CODES in the top-left, type the string exactly, and press SUBMIT. CORAL and SPOOKY are the two codes public trackers still treated as working on 10 November 2026. CORAL's Pearl amount is listed as 20 by most of those trackers and 40 by Destructoid.

What should I build first?

Feed the Bonfire to level 3, then craft Sawmills. Community guides from July 2026 put the Sawmill cost at 10 Wood and 2 Metal and tell you to build at least two. Crab Trap and Map Radar come next. Confirm every cost in the craft menu.

What is the difference between Pearls and Doubloons?

Pearls buy permanent classes and companion chests. Doubloons are the in-run merchant currency. A September 2026 developer note, reported on 10 November 2026, says Doubloons now save between runs and pay for companion upgrades.
