update 3 and Christmas are the latest codes!
Merge and Fight takes the best things from Plants vs Brainrots and Build a Zoo and combines them into a game where you have to build the ultimate crop field in order to defeat rare brainrots such as Los Tralaleritos. Now, getting to that point can take a long time, so we prepared the following Merge and Fight codes to help you a bit on your grind.
All Merge and Fight Codes List
By redeeming codes in Merge and Fight, you can obtain rare plant seeds, potions, gear items, and more. All of these are essential for defeating brainrots efficiently. Make sure to check out our Plants vs Brainrots codes as well for some exclusive items.

Why Are My Codes Not Working?
If you are inputting a Merge and Fight code but it doesn't work, first check your spelling, as codes are case-sensitive. You can also copy the codes and paste them to ensure they are entered correctly. If the code still isn't working, it's most likely expired. Merge and Fight codes are active for only a limited time, so redeem them as soon as they come out.
How to Get More Merge and Fight Codes
You can find fresh Merge and Fight codes by browsing the official MaF Discord server. However, since there is no dedicated Codes channel on it yet, it might take you a while to find a new code. Instead, you can bookmark this page and revisit it every now and then, as we will keep adding new codes as they get released.
How to Get More Free Rewards in Merge and Fight
You can obtain more free loot in Merge and Fight just by logging in and playing for a few hours every day. Similar to what codes reward you with, daily gifts include rare plant seeds, gear items, all kinds of potions, and more!
Merge and Fight FAQs
If your inventory gets full, go to the Sell Brain-rot NPC that is right across the Gear NPC. There, you can sell all the brainrots you don't need. Make sure to lock brainrots you do want to keep by right-clicking on them in your inventory beforehand.
You can obtain better plant seeds by upgrading your Conveyor Belt, which costs a set amount of cash per upgrade.
With each Brainrot Portal upgrade, new and better brainrots will start to spawn on it. Brainrot Portal upgrades scale with the total DPS of the plants in your field. So, you will have to grow some high DPS plants before you can obtain the rarest brainrots available.
