Why codes might not work

• The code has expired and the rewards were removed from the game.
• There is a typo, missing character, or extra space; Boom Sumo codes are case-sensitive and must match exactly.
• The code was already redeemed once on your Roblox account and cannot be used again.
• You are on an older server that does not have the latest build; rejoin the game or restart Roblox and try again.

Where to find more codes

New Boom Sumo codes are usually shared around big updates, visit milestones, and special events.
