Islands & Map — Every Verified Location
The ocean is the map, and the islands are the reason to leave your raft. Here's every location with a real source behind it — and a warning about the invented island tables circulating elsewhere.
Verified locations
The nearest island to your spawn — home to a Dinghy and an NPC trader. Usually your first landfall.
Hold out against waves of Ghost Pirates, then rescue the stranded crew — the game's rescue-mission thread.
Small rocks with one or two chests — quick loot stops between bigger sails.
Heavily guarded loot fortresses. The standing advice: don't try them solo.
Unlocked with the Transponder that drops after repelling the Night 6–7 alien invasion.
An enterable vessel whose container holds carry top loot — including up to two Medkits. Getting the doors open is a famous puzzle.
A June 2026 content update — frozen waters with their own dangers (and the Ice Mage class arrived alongside it).
Late-game content confirmed by walkthrough videos and the Fire Mage / Magma Staff / Magma Chest item family.
A vendor that appears as a map icon — sells Medkits among other stock. Sail over when you see it.
Also real but mechanically undocumented: the Outpost and the Oil Drill (players feed it fuel/wood) — both on our in-game verification list.
The island lists to ignore
Several wiki-style sites publish a confident eight-island world map — Starter, Jungle, Desert, Shipwreck, Volcano, Ice, "Kraken Zone", "Bermuda Island" — each with a named boss. Those names appear onlyon AI-generated sites, and the boss names contradict each other from site to site, which is what invented content looks like. The verified location names above come from sources that actually played. When our tested runs confirm more, they'll be added here with dates.
FAQ
How many islands are there in 100 Days At Sea?
No trusted source has published a definitive count. What's verified: Fisherman Island, Survivor Islands, Mini Islands, Tower/Fortress Islands and Alien Island, plus the Cargo Ship encounter, the Ice Region and Volcano content. The tidy 8-island tables on some sites (with names like 'Kraken Zone' and 'Bermuda Island') only appear on AI-generated wikis that contradict each other.
How do I get to Alien Island?
Survive the alien invasion event that lands around Night 6–7 — clearing it yields a Transponder, which unlocks the island.
What's on the Cargo Ship?
Container rooms with some of the best mid-run loot, including up to two Medkits per ship. Opening its doors is the tricky part — the door route is on our in-game verification list.
Is there a Kraken in 100 Days At Sea?
Yes — the Kraken shows up in player boss-fight content, and the Snorflord is another confirmed boss (it drops a Medkit). A full verified boss list doesn't exist yet anywhere; we're building one from tested runs.
