Question 1

What is Merge a Nuke?

Accepted Answer

Merge a Nuke is a Roblox game by Nuke The Game where you merge bombs into stronger nukes, earn passive cash (even offline), raid other bases, and lock your base to stay safe. This site is a fan-made guide to help you progress faster.

Question 2

What is the active code for Merge a Nuke?

Accepted Answer

As of August 1, 2026, try ATOMIC ($10,000 + 20 nukes), UPDATE2 ($10,000 + 10 nukes), then BOOM ($5,000). MAGMA was removed in the August 1 patch. Redeem via Shop (left) → Enter Code... box at the bottom → Redeem. Full list: https://mergeanuke.site/codes

Question 3

How do I redeem codes?

Accepted Answer

Launch Merge a Nuke on Roblox and tap Shop on the left to open the EXCLUSIVE SHOP panel. The code field sits at the bottom of that panel (labeled "Enter Code...") — type or paste your code there and tap Redeem. Codes are case-sensitive, so copy them directly from this page. Try ATOMIC, UPDATE2, and BOOM in that order.

Question 4

Why is a code not working?

Accepted Answer

Codes fail when they have expired, were already redeemed, or were typed wrong. MAGMA was removed August 1, 2026 — try ATOMIC, UPDATE2, and BOOM instead. Rejoin the game if you are on an old session.

Question 5

Do nukes earn cash while offline?

Accepted Answer

Yes. The official game description says your nukes earn cash every second, even while you are offline. Merge to your highest tier and lock your base before logging off so raids do not wipe your gains.

Question 6

How do I merge nukes?

Accepted Answer

Drag two nukes of the same merge level together — only identical tiers combine (2+2=4, 4+4=8, and so on). High-tier nukes cannot merge with lower bombs. Step-by-step guide: https://mergeanuke.site/beginner-guide#how-to-merge

Question 7

What Store upgrades should I buy first?

Accepted Answer

Community gameplay points to Spawn Speed first (a few thousand cash), then Spawn Tier so new nukes spawn at level 2+, then Max Spawn. Upgrade Lock Base duration before long merge sessions. Full priority list: https://mergeanuke.site/upgrades

Question 8

What is the center city in Merge a Nuke?

Accepted Answer

The map center has a PvE city target separate from player bases. It opens on a long cooldown (often 40+ minutes in gameplay footage), pays large rewards, and works best with your highest-damage nukes. It is not the same as raiding another player.

Question 9

What are commanders in Merge a Nuke?

Accepted Answer

Commanders are special units you equip for passive buffs — auto-merging (Salvager), cash boosts (Spotter), or +15% damage (Sovereign). The July 25 patch moved the Commanders button to Inventory; August 1 added Mimic (Admiral) to the Base Pool. See all 35 types and how to capture them: https://mergeanuke.site/commanders

Question 10

How does raiding work?

Accepted Answer

Launch your nukes at another player's base to steal cash — but only if their Lock Base shield is down. Getting raided can wipe nukes from your board. PvP and center city guide: https://mergeanuke.site/raid

Question 11

When should I start raiding?

Accepted Answer

Wait until your income is stable and your base is locked. Raiding too early can stall your growth, so build a reliable economy first.

Question 12

How do I protect my base?

Accepted Answer

Lock your base before going offline, keep your layout organized, and safeguard your highest-tier nukes so you don't lose hard-earned progress.

Question 13

What should beginners upgrade first?

Accepted Answer

Focus on income upgrades early. A higher earning rate funds everything else, so prioritize cash flow before stronger nukes or cosmetic buys.

Question 14

When does Merge a Nuke update?

Accepted Answer

Nuke The Game ships new content every Friday — codes, balance tweaks, and new nukes are possible. Join the official Roblox group and check this wiki after each Friday patch.

Question 15

Can I play Merge a Nuke on mobile?

Accepted Answer

Yes. Merge a Nuke supports Desktop, Mobile, Tablet, and Console per the official Roblox game page. On mobile, tap and drag to merge; zoom out if your grid feels cramped.

Question 16

Is rebirth worth it?

Accepted Answer

Yes — rebirth is required to unlock the highest Index nukes beyond the mid-game cap (community runs report ~35 tiers before rebirth, with more after each rebirth tier). Rebirth 3 unlocks Nuke Mutations, Nuke Locking, and Self Destruct (August 1, 2026). Rebirth 8 (July 13) needs Overclocker + Barrier. Rebirth 9–10 add +120% / +130% cash; Rebirth 10 also unlocks Admiral Mutations and a second Mutation slot. Rebirth only when growth has clearly stalled.

Question 17

Is mergeanuke.site official?

Accepted Answer

No. mergeanuke.site is an independent fan-made Merge a Nuke Wiki. It is not affiliated with Roblox Corporation or Nuke The Game. For official news, use the Roblox game page and developer group.
