Why codes might not work
- The code has expired and is no longer accepted by the game, even if it worked in the past.
- The code was typed with a mistake, extra space, or wrong capitalization; codes are case-sensitive and must match exactly.
- The code was already redeemed on your Roblox account, so it cannot be used a second time.
- The game server or your client is outdated; closing Black Grimoire, rejoining a fresh server, and trying again can sometimes help.
