100 Days At Sea Codes — the Verified List
The historical code trail, redemption steps, and an explicit verification boundary. Codes expire quickly, so a tracker listing is not labelled "working" here until a current in-game redemption confirms it.
100 Days at Sea codes status (reviewed August 9, 2026)
POTION20 PearlsRecheck in gamePreviously reported active on August 5. It has not been redeemed again after the game's August 8 update, so test it in-game before treating it as current.
CHAOS20 PearlsRecheck in gamePreviously reported active by two trackers. That is historical tracker evidence, not an August 9 in-game confirmation; test it after POTION.
CORRUPT20 PearlsRecheck in gamePreviously reported active beyond its original July window. It now needs a fresh in-game redemption before this page can call it working again.
HERO20 PearlsExpiredExpired July 17 — it lasted just over a week alongside the Hero class. Two trackers still listed it as active on July 31; it remains marked dead until an in-game redeem proves otherwise.
ALIENS20 PearlsExpiredExpired July 10. It was tied to the Alien Invasion event; later active labels on tracker sites are treated as stale.
20Pearls20 PearlsExpiredExpired July 3. This was the first code when the redemption system launched in late June 2026.
No code is labelled current until it passes a post-update in-game redemption. New codes usually appear on the official Discord first; the August 5 tracker snapshot is retained above as history, not presented as an August 9 guarantee.
How the 100 Days at Sea codes system works
Codes are not an original feature of this game. They arrived around June 27, 2026 — roughly eight months after launch — when a CODES button appeared at the top-left of the screen and the first code, fittingly named 20Pearls, went out with it. Pro Game Guides first published its codes article for the game on that same date, which is about as close to a launch stamp as an unofficial feature gets.
Three things have held true for every code since, and they are worth knowing because they let you sanity-check any list you find:
- Every code pays exactly 20 Pearls. Not one confirmed code has ever granted anything else — no items, no classes, no boosts. A list promising a free class unlock or a 500-Pearl jackpot is inventing.
- Codes track events, not a calendar. Each one has ridden a content drop:
20Pearlswith the codes system itself,ALIENSwith the alien content,HEROwith the Hero class,CORRUPTwith the July 17 Corruption update, andCHAOSimmediately after the July 24 patch. If you want to predict the next code, watch the update timeline rather than the calendar. - They die on a roughly weekly ladder.Line up the expiry dates so far — July 3, July 10, July 17, then CORRUPT's reported window closing around July 24 — and the turnover is almost exactly seven days apart, with each individual code living about two to three weeks. That is why any undated codes list is worthless within a fortnight.
New codes surface first on the developer's official Discord server and the Stranded Devs Roblox group; both Pro Game Guides and Game Rant name those two channels as the upstream. Everything that reaches a codes page — including this one — is downstream of an announcement made there.
Three trackers, three different answers
Here is something no other codes page will show you. On July 26, 2026 we re-read three of the biggest code trackers back to back. They agree on the new code and they agree on the oldest one. On everything in between, they flatly contradict each other:
| Code | Pro Game Guides | Game Rant | Beebom | Our call |
|---|---|---|---|---|
| CHAOS | Active (new) | Page gone (404) | Active (new) | Live — redeem it first |
| CORRUPT | Active | Page gone (404) | Active | Live — window extended |
| HERO | Active | Page gone (404) | Active | Dead per our Jul 17 record — trackers look stale |
| ALIENS | Active | Page gone (404) | Expired | Almost certainly dead |
| 20Pearls | Inactive | Page gone (404) | Expired | Dead — unanimous |
This is not a scandal, it is just how codes coverage works: a code quietly stops functioning, and each site removes it whenever someone next tests. Game Rant is the quickest to retire codes here; Pro Game Guides keeps them listed longest. Nobody is lying — but it does mean "listed as active" is not the same as "works", on any site including this one.
The practical upshot is cheerfully simple: a dead code costs you nothing but an error message. Work down the list from the top, newest first, and stop caring which page was right.
What 20 Pearls actually buys you
Pearls exist almost entirely to unlock classes, so the honest way to value a code is to price it against that shop. At 20 Pearls a code, here is the exchange rate:
- Two codes buy Sailor, the cheapest class at 40 Pearls.
- Two and a half codes buy Medic (50), the entry pick worth having because it starts every run holding a Medkit.
- Six codes buy one Magma or Pirate companion chest at 120 Pearls — a single roll, not a guaranteed companion.
- Thirty-seven and a half codes buy Fire Mage at 750 Pearls, the class the tier lists rate best in the game.
At roughly one new code a week, codes alone would take you the better part of a year to reach the 750-Pearl shelf. Treat them as free top-ups you redeem in ten seconds, and treat daily quests, badges and achievements as the actual Pearl economy.
⚠️ Fake codes to ignore
These strings are published as "working codes" by several AI-generated wiki sites, but appear in none of the trusted trackers and have no known redemption record:
SEAADVENTURESTRANDEDDEVS100DAYSIf a site lists these as active, that tells you how the rest of its content is written.
How to spot a fake codes list in thirty seconds
The three strings above are the giveaway, but you will not always be lucky enough to catch a site publishing a known fabrication. These five checks work on any codes page for any game:
- Look for a date on the list itself.Not "September 2026" in the title — a specific check date next to the codes. With a seven-day turnover, a list without one is telling you it has not been touched.
- Check the rewards column for variety.Every real code in this game has paid 20 Pearls, full stop. Mixed rewards — pearls plus items plus "a free class" — mean somebody generated a plausible-looking table rather than copying a real one.
- See whether the expired list ever grows. A genuine tracker accumulates dead codes over time, because retiring them is the actual work. A list with five active codes and no expired section has never retired anything.
- Cross-examine the site's other pages. This is the fast one. Open its classes page: if it says there are 23 classes rather than 29, it is working from stale copy. Open its boss list: if it names a "Sand Worm" or a "Frost Giant", those appear nowhere in the game's official badge list and it is inventing content wholesale. A site that invents bosses invents codes.
- Test the cheapest claim first.Codes take ten seconds to try and cost nothing. One failed redemption on a site's newest code tells you more than any amount of reading.
How to redeem
- In a run or lobby, press the CODES button at the top-left of the screen.
- Open the Codes tab and type the code exactly as written (codes are case-sensitive in most Roblox games — copy ours as-is).
- Hit Submit. Pearls are added instantly.
If a code doesn't work
An "invalid code" message is almost never a bug. In descending order of likelihood:
- It expired. Given the weekly turnover documented above, this is the answer roughly nine times out of ten — and it is the first thing Pro Game Guides tells you to check too. Anything below the newest entry on our list is a coin flip.
- A character is wrong. Beebom attributes invalid-code errors squarely to mistyped letters and numbers, and recommends copying the code and pasting it straight into the box rather than typing it. Do that —
20Pearlsin particular is easy to fumble. - Your client is running an old version. Beebom also notes that when a fresh update drops you may need to restart the game to avoid a version error. Since codes arrive attached to updates, a brand-new code and a stale client are a common pairing — rejoin and try again.
- You are in the wrong game. This game is openly modelled on 99 Nights in the Forest and shares an audience with it, so codes get swapped between the two in comment sections constantly. A 99 Nights code will never work here.
What will not fix it: waiting. Codes in this game do not come back once retired — none of the four expired entries above has ever been reissued.
FAQ
How do I redeem codes in 100 Days At Sea?
Press the CODES button at the top-left of the screen, open the Codes tab, type the code exactly as written and hit Submit. Rewards (Pearls) land instantly.
Why do codes from other websites not work?
Two reasons. First, codes in this game genuinely expire fast — roughly 2–3 week windows. Second, some sites publish invented codes that never existed: SEAADVENTURE, STRANDEDDEVS and 100DAYS circulate on AI-generated wikis but appear in none of the trusted code trackers.
Where do new 100 Days At Sea codes come from?
The developer's official Discord server — codes are posted in the announcements/updates channels, usually alongside game updates. Code names track events (ALIENS arrived with the alien event, HERO with the Hero class).
What are Pearls used for?
Mainly unlocking Classes — the class shop runs on Pearls, from the 40-Pearl Sailor up to 750-Pearl classes like Fire Mage. You also earn Pearls from daily quests, badges and companion chests.
