Update: We checked for new Merge Your Army codes on January 28, 2026, but there were no changes.
Merge Your Army uses redeemable codes to grant free cash, gems, and potions that speed up early upgrades and make zombie waves easier to handle.
Quick answer: Open Merge Your Army on Roblox, tap the Shop icon on the left, scroll to the Codes section at the bottom, enter a working code such as 5MVISITS or UPDATE4, then press Redeem; if the code is valid and unused, the reward is added to your resources immediately.

How to redeem Merge Your Army codes
Step 1: Start Merge Your Army from its Roblox page at https://www.roblox.com/games/72520655498867/Merge-Your-Army and wait until your base loads fully.
Step 2: Click or tap the Shop icon (shopping basket) on the left side of the screen to open the in-game shop menu.
Step 3: Scroll to the bottom of the shop menu until you reach the Codes section and locate the text box for entering codes.
Step 4: Type or paste one working code into the text box exactly as listed, then press the Redeem button.
Step 5: Check the top of the screen and your resource bars; if the code is valid and unused, the reward (cash, gems, or a potion) is added instantly.
How to confirm Merge Your Army code redemption
Successful redemption is indicated by an in-game confirmation and a visible increase in the relevant resource. Cash totals rise immediately, gems increase in your gem counter, and potions appear in your consumable inventory for use during runs or in your base management menu.
If nothing changes after you press Redeem and no success message appears, the code either has already been used on your account, has expired, or was entered with a typo.
Why Merge Your Army codes may not work
Several common reasons prevent codes from redeeming:
- Typographical errors: Codes must match exactly, including capital letters; any extra spaces before or after the text will cause failure.
- Expired codes: Codes such as
8KCCUandUPDATE3have been retired and no longer grant rewards. - Already redeemed: Each code can be used once per account; if you have claimed it previously, the game will not award the reward again.
When a code does not work, verify the spelling first. If it still fails after careful entry and your resources do not increase, treat it as expired or already claimed.
How to get more Merge Your Army codes
New codes are typically released around content updates and milestones such as visit or player-count goals. To catch them quickly, join the official Merge Your Army Discord server and monitor announcement channels for new code posts. Returning to the game’s community hubs on Roblox can also reveal fresh rewards tied to updates or events.
Within the game itself, do not ignore the free treasure chest in the lobby; turning around from the spawn point and opening this chest grants an additional burst of cash and gems without needing a promo code, which complements the rewards listed above.
