Ready to claim your free rewards? Follow my foolproof step-by-step guide to redeem your Boom Sumo codes in seconds! I’ve included screenshots and detailed instructions to make it impossible to get wrong.
First, fire up Roblox and search for “Boom Sumo” or click here to play directly. Make sure you’re on a stable server with good connection to avoid any issues during redemption.
Once you’re in the game lobby, look for the Codes NPC standing near the leaderboard area. He’s usually easy to spot – just look for the character with a code symbol above their head!
Pro Tip: If you can’t find the Codes NPC immediately, press the “M” key to open your map and look for the code icon. This will save you time wandering around the lobby!
Walk up to the Codes NPC and press the E key to interact with them. This will open up the code redemption menu where you can enter your codes.
In the input field that appears, type or paste one of the active codes from my list above. I recommend copying and pasting to avoid any typos – even one wrong letter can make a code invalid!
Click the golden “Submit” button and watch as your rewards instantly appear in your account! You’ll see a confirmation message showing exactly what you’ve received.
Go back to Step 4 and repeat the process for each active code. You can redeem all codes in one session, so take advantage of all the free rewards while they last!
Sometimes codes don’t work on the first try – don’t worry! I’ve been there too. Here are the most common issues and how to fix them:
Problem: You get an “Invalid Code” error even though you’re sure the code is correct.
Solution:
Problem: The system says you’ve already redeemed a code you haven’t used before.
Solution:
Problem: A code that was working yesterday suddenly stopped working.
Solution:
Problem: You successfully redeemed a code but didn’t get the rewards.

The developers at ProjectNorth regularly release new codes through their official channels:
Through my research, I’ve identified when new codes are most likely to be released:
The easiest way to never miss a code? Bookmark this page (press Ctrl+D) and check back regularly! I update this guide multiple times per week to ensure you always have the latest working codes.
Join the Discord server and enable notifications to get instant alerts when new codes are dropped. This is how I get many codes before they’re widely circulated!
Now that you’ve got your free Mon and Keys, let me share some insider tips to help you dominate the arena!
Boom Sumo is an intense Roblox fighting game where your main goal is to push opponents off the map and be the last one standing. It’s all about skill, timing, and strategy – no luck involved!
As you play and win matches, you’ll rise through the sumo ranks. The ranking system includes various levels from beginner to master, with each rank requiring different achievements and win conditions.
Based on my research, new codes are typically released weekly to bi-weekly, with additional drops during special events, holidays, and when the game reaches milestone visits. The developers at ProjectNorth are quite active with code releases!
Mon is the primary in-game currency used to purchase new moves, abilities, and upgrades from the in-game store. Keys are special items used to unlock Omnichests, which contain rare and powerful items that can give you significant advantages in battle.
Unfortunately, no – each code can only be redeemed once per Roblox account. This is why it’s important to redeem all active codes as soon as possible before they expire!
Codes expire to maintain game balance and encourage players to stay engaged with the community. The developers use codes as special promotional tools for events, updates, and milestones, which is why they have limited lifespans.
While I strive to maintain the most comprehensive list possible, occasionally developers release surprise codes through Discord or social media that might take a few hours to appear here. This is why I recommend joining the official communities for the most up-to-date information!
First, double-check that you’ve entered the code correctly (they’re case-sensitive!). If it still doesn’t work, try joining a different server or restarting the game. If the issue persists, the code may have recently expired – check back here for updates!
The best way to reach the developers is through their official Discord server or the ProjectNorth Roblox group. They’re quite active in the community and often respond to player feedback and questions.
Yes! Boom Sumo is completely free to play on Roblox. While there may be optional in-game purchases, you can enjoy the full game experience without spending any money, especially with all the free codes available!
