100 Days at Sea gives out one new code with most weekly updates, and each one is worth a small stack of Pearls. Code lists online disagree a lot on this game: the same code shows up as "active" on one site and "expired" on another. This page splits them into codes that most trackers agree work, codes that might still work, and codes that are dead, with the date we checked.
Quick answer (checked November 10, 2026, 08:10 UTC): There are 2 active 100 Days at Sea codes: CORAL and SPOOKY, each worth Pearls (20 Pearls on most lists). CORAL is the newest; it arrived with the Sunken Treasure update on November 6–7, 2026. RIVAL, RAFT and SURVIVOR might still work, but trackers disagree. Type them in capitals, exactly as shown, to be safe.
Applies to the Sunken Treasure update (November 6–13, 2026). We re-check this page every week and after each Friday update.

What are the active 100 Days at Sea codes?
We compared seven code trackers updated between November 2 and November 10, 2026: Roblox Den, RoCodes, Beebom, Destructoid, UrGameTips, GamesRadar+ and Eurogamer. We also read Pro Game Guides (November 7) and PCGamesN (last updated September 25). A code goes in the active table only if at least five trackers list it as working and none of the trackers updated since November 7 (Roblox Den, RoCodes, Destructoid, Beebom and UrGameTips) calls it expired. We cross-checked sources; we did not redeem them on a test account.
| Code | Reward | Added | Listed as working by |
|---|---|---|---|
| CORAL | 20 Pearls (Destructoid says 40) | November 7, 2026 | 6 trackers |
| SPOOKY | 20 Pearls | October 23, 2026 | 5 trackers |
CORAL is the safest one to redeem: every November list that mentions it calls it active, including Roblox Den, which tests codes in-game. It lines up with the Sunken Treasure update ("Reintroducing Diving & Sunken Loot!") that the developer posted for November 6. SPOOKY came with the Halloween event that ran October 23–31. Roblox Den now marks SPOOKY as "check" and Eurogamer moved it to expired on November 3, so redeem it now; it is the next one likely to die.
Codes that might still work
Trackers disagree on these three. They cost nothing to try:
- RIVAL (20 Pearls). The best bet of the three. Roblox Den, which tests codes in-game, marks it active, and so do RoCodes, Beebom, UrGameTips, Eurogamer and PCGamesN. It is only left out of the table above because Destructoid (November 7) and GamesRadar+ list it as expired.
- RAFT (20 Pearls). Active on RoCodes and UrGameTips; expired on Destructoid. Roblox Den doesn't list it at all.
- SURVIVOR (20 Pearls). Active on Beebom and UrGameTips; "check" on Roblox Den; expired on Destructoid, PCGamesN, Eurogamer and GamesRadar+. The least likely to work.
If one of these says the code is invalid after you've checked the spelling in a fresh server, it has most likely expired. Move on.
Which 100 Days at Sea codes have expired?
These no longer work. Dates are from RoCodes' tracker, which logs when a code was added and when it stopped working.
| Code | Reward | Active from | Expired |
|---|---|---|---|
| CORRUPT | 20 Pearls | July 18, 2026 | August 7, 2026 |
| SKELLY | 20 Pearls | September 12, 2026 | October 23, 2026 |
| CLASSES | 20 Pearls | August 22, 2026 | September 12, 2026 |
| DECORATE | 20 Pearls | August 8, 2026 | September 12, 2026 |
| 20Pearls | 20 Pearls | June 27, 2026 | September 12, 2026 |
| POTION | 20 Pearls | August 1, 2026 | August 7, 2026 |
| CHAOS | 20 Pearls | July 25, 2026 | August 7, 2026 |
| HERO | 20 Pearls | July 11, 2026 | August 7, 2026 |
| ALIENS | 20 Pearls | July 4, 2026 | August 7, 2026 |
CORRUPT is still marked "check" on Roblox Den, but RoCodes, PCGamesN, Eurogamer, Beebom and GamesRadar+ all list it as expired. Beebom still shows CLASSES and DECORATE as active, but RoCodes, Roblox Den, Destructoid, Eurogamer and GamesRadar+ all list both as expired.
The codes follow the updates. HERO was announced by name in the game's July 10 event post on its Roblox page: "💎 NEW CODE - HERO", with bonus Pearls until July 13. ALIENS matched the Alien Invasion update, CHAOS the Chaos Master class, DECORATE the Decorations update and CLASSES the Big Class Update.

Why is my 100 Days at Sea code not working?
- It expired. Codes here last anywhere from about a week to a few months. Most July codes died together on August 7.
- You typed it wrong. Roblox Den says codes are case-sensitive, so type CORAL in capitals and don't copy a trailing space.
- You already used it. Each code works once per account.
- Your server is old. If an update just dropped, leave and join a new server, then try again.

What are Pearls used for?
Pearls are the reward every code gives. Code trackers say you spend them on classes, which change what you start a run with; Destructoid notes the strongest classes start with weapons, armor and ammo. The developer's update posts back that up: the Knight class "Starts with Knight Armor, Claymore, +30% Damage reduction, and +15% Sprint Speed", and the Fire Mage starts with the Magma Staff. The developer also runs Bonus Pearl Weekends; the most recent ran October 9–11, 2026.
Don't confuse Pearls with Doubloons, the currency you find in chests during a run. Since the September 18 update, Doubloons save between runs and pay for Companion upgrades.
Codes give 20 Pearls each, so a full set of active codes won't buy much on its own. They help most at the start, when you're saving for your first class.
Some classes can also be bought for Robux. The developer's September posts list Max Level class bundles, including the reworked Swordsman at 799 Robux. If you plan to buy one:

How do you get new 100 Days at Sea codes?
New codes nearly always arrive with an update, and most updates go live on Friday evenings US time (around 21:00–23:00 UTC). Watch these official channels:
- The game's Roblox page. Stranded Devs posts every update as an event on the game page. That's where HERO was announced.
- The official Discord. The 100 Days at Sea server has about 24,000 members. The link sits at the bottom of the game page, but Roblox only shows social links to accounts that meet its age-check rules, so younger players may not see it.
- The Stranded Devs Roblox group. It has about 1.45 million members. Joining it is free.
The next update on the schedule is Denizens of the Deep on November 13, 2026: "Fisherman Joe has a job for you! Help him build his new Aquarium and catch rare and exotic creatures to put on display." Expect a new code around then.
What is 100 Days at Sea?
100 Days at Sea is an open-world survival game by Stranded Devs. Its description says it was "inspired by 99 Nights in The Forest". You're sent into the Bermuda Triangle, and the goal is to survive 100 days. Since the May 2 Island Survival update you spawn on an island with trees and debris to get you started, then build out to sea. You hook resources with a harpoon, build your raft into a base with walls and defenses, and visit islands for weapons and loot. After you survive 100 days once, Challenge Mode unlocks six harder tiers. The new Pro Servers, added November 2, are only for players who have reached 100 days.
As of November 10, 2026 at 08:10 UTC, the Roblox Games API and its votes endpoint showed:

FAQ
What is the newest 100 Days at Sea code? CORAL. It came with the Sunken Treasure update on November 6–7, 2026, and gives Pearls.
How many Pearls does a 100 Days at Sea code give? 20 Pearls on nearly every list. Destructoid lists CORAL at 40 Pearls; no other tracker does.
Where is the codes button in 100 Days at Sea? In the top-left corner of the screen. Click CODES, type the code into the Enter Code box and press SUBMIT.
Why does every site show different 100 Days at Sea codes? Codes expire without notice, and each tracker re-checks on a different day. That's why we list RIVAL, RAFT and SURVIVOR separately: the sources split on them.
When do new 100 Days at Sea codes come out? Usually with the Friday update. The next one is Denizens of the Deep on November 13, 2026.
Is 100 Days at Sea the same game as 99 Nights in the Forest? No. Stranded Devs made 100 Days at Sea, and its description credits 99 Nights in the Forest, by Grandma's Favorite Games, as the inspiration. Codes from one game don't work in the other.
