Merge a Nuke Codes (June 2026) -- All Active & Expired Codes
Here's every working Merge a Nuke code for June 2026, the rewards each one pays out, and the exact steps to redeem them inside the game.
Merge a Nuke is a Roblox merge-and-build game where you fuse small bombs into progressively larger nukes, sell them for Cash, and reinvest that Cash into faster spawners and bigger payouts. Codes are the quickest way to skip the early grind. A single redemption can hand you 10,000 Cash, which is enough to fund a few merge tiers before you've even unlocked the second spawner.
The developers release codes in bursts, usually tied to the weekly Friday update or a player-count milestone. Because there's no in-game notification when a code dies, the smart move is to redeem everything the moment it appears. We track this page and refresh it whenever a new code drops or an old one stops working.
All Active Merge a Nuke Codes (June 2026)
These codes are currently working as of June 21, 2026. Together they pay out 15,000 Cash plus 30 free Nukes, and since none have expired yet, the full haul is still claimable on a fresh account.
| Code | Reward | Status |
|---|---|---|
| ATOMIC | 20 free Nukes | Active |
| UPDATE2 | 10,000 Cash + 10 Nukes | Active |
| BOOM | 5,000 Cash | Active |
UPDATE2 since it pays the most.
The ATOMIC code that the developers teased is now live and handing out 20 free Nukes, so we've added it to the active table above. Redeem it alongside the others while it lasts.
All Expired Merge a Nuke Codes
Good news for newer players: no Merge a Nuke codes have expired yet as of June 2026. The game is young, and the developers haven't rotated out the launch codes. We list dead codes here for reference as soon as any stop working.
| Code | Status |
|---|---|
| None yet -- check back | Expired |
Once a code goes dark, entering it returns an "invalid code" message rather than crediting Cash. That's the only signal the game gives, so there's no reason to keep retyping a code that has stopped working.
How to Redeem Codes in Merge a Nuke
Redeeming takes about ten seconds once you know where the box is. The Codes menu sits inside the Store, not on the main HUD, which trips up a lot of first-time players.
- Open Roblox and launch Merge a Nuke, then wait for the world to fully load.
- Click the Store button on the left side of the screen.
- Scroll to the bottom of the Store menu to find the Codes section.
- Type or paste a working code into the
Type Code Heretext box, exactly as written. - Press the Redeem button and watch the free Cash appear in your balance at the top of the screen.
If nothing happens, double-check the spelling and capitalization. Pasting straight from this page removes the guesswork, because UPDATE2 and update2 are not treated as the same string.
Where Do New Codes Come From?
Most Merge a Nuke codes drop alongside the weekly update, which the team ships on Fridays. A new spawner tier, a raid tweak, or a fresh event usually arrives with a code attached to celebrate the patch.
The official Discord server is the first place codes appear. Developers post them in the announcements channel right after a build goes live, often hours before the major code-listing sites catch up. Joining the server is the fastest route if you want codes the same day they release.
Milestone codes are the other source. When the game crosses a visit or concurrent-player threshold, the team hands out a thank-you code. These tend to pay more Cash than the routine weekly drops, so they're worth watching for.
We monitor the Discord and the game's group feed, then verify each code in-game before adding it here. That verification step matters because fan sites sometimes repost codes that have already expired.
Tips for Getting the Most Out of Merge a Nuke
Redeem codes before you spend a single dollar of starting Cash. Dropping 15,000 Cash into your account early lets you skip past the slowest merge tiers, where each upgrade can otherwise take several minutes of manual merging.
Spend on spawner speed first. The biggest bottleneck early on is how fast new bombs appear. A faster spawner means more merges per minute, which compounds into more Cash than buying a single high-tier nuke outright.
Keep your merge board tidy. Leaving low-tier bombs scattered around clogs the grid and blocks new spawns. Merge aggressively, sell the high tiers, and you'll keep the board flowing instead of stalling out.
Don't sit on Cash. Idle currency earns nothing, so reinvest it into the next spawner or storage upgrade as soon as you can afford it. The players climbing the leaderboard are the ones constantly cycling Cash back into upgrades.
