Demon Soul Simulator puts you in the middle of a Demon Slayer-inspired battle against demons, where gold, crystals, and chest pulls decide how fast you grow stronger. Codes from the developer hand out free currency and chests that speed up that process without extra grinding.
Working Demon Soul Simulator codes
Redeem these while they last, since the developer swaps them out without much notice.

The wnxu8d code is valid until July 31, 2026, according to the in-game description, so redeem it before that date passes. The membership-tier codes (50members through 400members) reward chests of increasing rarity and don’t appear to have an expiration tied to them yet.
How to redeem codes in Demon Soul Simulator
You’ll know a code worked when the reward (gold, crystals, talent points, or chests) shows up in your inventory or currency counter right after pressing Ok. If nothing changes, double-check the spelling, since codes are case-sensitive and won’t register if typed incorrectly.
Expired Demon Soul Simulator codes
These codes no longer work, so don’t waste time trying to redeem them.

Where to find new codes
The developer posts new codes on the game’s official Discord server, often alongside patch notes and bug-fix compensation codes. The in-game description also lists fresh codes directly, so checking it after each update is worth doing.
Bookmark this list and check back regularly, since codes tend to expire without warning and the reward pool shifts with each content update.
