Block Mayhem codes not working? Common fixes

A failed redeem usually has a simple cause. Before you write off a Block Mayhem code as dead, run through this checklist:

1. Copy the code exactly. No extra spaces; Roblox codes are usually case-insensitive, but typos break redemption.
2. The code may have expired. Compare with the Block Mayhem expired codes list above.
3. Account or level requirements. Some codes need a minimum level or progress; the in-game message will say so.
4. Server or update delays. Right after an update, redemption can glitch; rejoin Block Mayhem on Roblox and try again.
5. Official sources first. New codes ship via developer social channels; we mirror them here when verified.

If a fresh code fails for every player, the source probably mistyped it. Compare the spelling against the developer’s Discord or X announcement.
