Demon Soul Simulator drops you into Demon Slayer’s world and gives you a choice most games would not: join the slayers, or become one of the demons they hunt. Either way, power comes from Souls — the currency that feeds the gacha where the series’ fighters are unlocked — and from the chests that hold their pieces.
The codes below are the current verified set, headlined by a brand-new drop for the fastest hundred players and a handful of Halloween leftovers that will not survive many more updates. Seven codes are standing; over a hundred have already fallen.
All New Demon Soul Simulator Codes
- b1spz6f2u: Free rewards (first 100 players only) (==NEW==)
- wnwi2s: 30 Shadow Pumpkins (==NEW==)
- e92n2i: 50 Halloween Candy
- 2n8d79: 50 Halloween Candy
- wuwox: 40k Gold
- 1sxj82x: 10 Legendary Chests
- shiverandsubgoated: 30 Sashimi
About that first code: b1spz6f2u is capped at the first 100 players who redeem it, which makes it the rare Roblox code with a genuine first-come-first-served race attached. If you are reading this close to the update, try it before anything else on the list — the chests and Gold from the other codes will still be there in five minutes, but this one may not. And since the Halloween candy codes are seasonal leftovers, work through the whole list in one sitting rather than saving some for later.
Expired Demon Soul Simulator Codes
This game burns through codes faster than almost any other on Roblox — well over a hundred have been retired, including some that were still being listed as working only days ago:

- Click OK and the rewards are yours.
How to Get More Demon Soul Simulator Codes
The official Demon Soul Simulator Discord server is where the developer, WhiteDragonCN, posts news first, and the same account shares drops on X while the MADRABBITGAME YouTube channel covers updates. Joining the Diligent Farmer Roblox group also pays out a free in-game reward the next time you log in. New codes here are tied to updates and milestones and often die within a single update cycle, so bookmark this page and check back right after every patch.
Why Are My Demon Soul Simulator Codes Not Working?
Double-Check for Typos: Almost every code in this game is a random-looking string of lowercase letters and digits — b1spz6f2u versus a mistyped b1spz6f2n is an easy mistake, and the game treats them as completely different codes. Always copy and paste rather than typing.
The Code Has Expired: Codes retire without warning here, frequently when the next update lands; the member-milestone chest codes that worked for months were switched off in the latest clear-out. If the spelling is right, the code has almost certainly expired — compare it against the list above.
The Player Cap Has Been Hit: A few codes, like the newest one, are limited to a set number of redeemers (the first 100 players). Once the cap is hit, the code stops working even though it has not technically expired, so a failed b1spz6f2u most likely just means you were beaten to it.

Conclusion
Seven working codes are on the table right now, and one of them is a 100-player race — so redeem b1spz6f2u first, clear the Halloween candy codes while they last, and open those Legendary Chests. We will keep this list pruned as the next update does its usual damage.
