Why codes might not work

The code has expired or was limited-time only.
There’s a typo or extra space — codes are case-sensitive.
The code was already redeemed on your account.
The server or client needs a refresh; rejoin or restart and try again.

Where to find more codes

Check the official Demon Soul Simulator page on Roblox, the community Discord server, the developer’s X account, and the official YouTube channel for new code drops and event updates. Bookmark this page — we update code lists weekly.

Codes are time-limited and case-sensitive; enter them exactly as shown. Avoid unofficial “code generators” and never share your account details to claim rewards.
