100 Days at Sea Guides Hub

Task guides for the opening raft, codes, classes, companions, bosses, islands, night raids, and day 100. Read the beginner guide first, then the page that matches the problem you have.

Opening

Start with Beginner Survival if the raft is not making planks yet. Use Bonfire and Raft for station costs, Codes and Pearls before you spend, and Classes before you buy anything past 50 Pearls.

After the raft is stable

Boss Objectives lists only fights named on official badges. Islands and Seeds separates those biomes from unverified seed claims. Night Survival is the defense chapter. Day 100 is the badge ladder and challenge tiers.

FAQ

100 Days at Sea guide 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.
