What Is Merge a Nuke
Merge a Nuke is a Roblox merge-and-raid game built by the developer Nuke The Game. The loop is simple to learn and hard to put down: buy bombs, drag identical ones together to merge them into bigger nukes, and watch your Cash per second climb. Those nukes keep paying out even when you log off.
The game has grown fast. As of June 11, 2026 it has passed 8 million visits, sits at 77,319 favorites, and peaks around 25,000 concurrent players, with a like ratio near 93 percent. New updates ship most Fridays, which is when fresh codes and new nuke tiers tend to drop.
What sets it apart from a plain idle game is the PvP layer. You're not just merging in a vacuum. Other players can raid your base and take your Cash, so every session is a balance between building up your nukes and keeping a lock on the door.
If you've played other 2026 merge and tycoon hits, the rhythm will feel familiar. It borrows the satisfying combine-and-collect loop from merge games and bolts on the steal-and-defend tension that made titles like Steal a Brainrot blow up. The result is a game you can idle through or grind hard, depending on how aggressive you want to be with raids.
Getting Started in Your First Session
The opening few minutes set the tone for your whole run. Don't overthink it. Buy a couple of cheap bombs, merge the first duplicates you get, and let the Cash start flowing before you touch anything else.
- Open the shop and buy two or three starter bombs to fill part of your grid.
- Drag identical bombs together to merge them into your first proper nuke.
- Collect the Cash that builds up and reinvest it into more bombs to merge.
- Press the lock button to seal your base before you do anything risky.
- Open the Store and redeem UPDATE2 and BOOM for free Cash and Nukes.
- Only after your income is steady should you scout for a base to raid.
Follow that order and you'll avoid the two biggest beginner traps: spreading Cash too thin across low-tier bombs, and leaving the base open while you wander off to raid.
Core Mechanics
Three systems drive everything in Merge a Nuke: merging, passive Cash, and raiding. Get comfortable with all three and you'll outpace players who only grind one of them.
Merging Bombs Into Nukes
Merging is the heart of the game. Buy a bomb from the shop, place it on your grid, then drop a second identical bomb next to it. The two fuse into a single higher-tier nuke that earns more Cash per second than the two pieces did separately.
The tier ladder runs from D-tier starter bombs up through C, B, and A-tier merged nukes, topping out at the S-tier Mega Nuke. Each step up is a meaningful jump in income, so the goal is to keep feeding duplicates into the chain rather than letting low-tier bombs pile up.
| Tier | What It Is | Role in Your Run |
|---|---|---|
| D-tier | Starter bomb / basic nuke | Cheap merge fodder, never your end goal |
| C-tier | Basic merged nuke | Your first real income bump |
| B-tier | Mid-tier merged nuke | Enough income to start raiding |
| A-tier | Advanced merged nuke | Strong offline earner for mid-to-late game |
| S-tier | Mega Nuke | Top-tier payout and bragging rights |
A practical milestone: aim to hold at least one B-tier nuke before you spend serious time raiding. That tier usually produces enough Cash per second that a failed raid won't set you back to square one. Treat D and C-tier pieces as ingredients, not investments. They exist to be merged, fast.
Passive Cash and Offline Earnings
Every nuke on your grid pays out Cash per second, and that income never stops. It keeps stacking while you're offline, so you'll log back in to a fat pile waiting to be collected and reinvested.
This is why merging up matters so much. A single A-tier nuke can out-earn a grid crammed with C-tier ones, and it earns that whether you're playing or asleep. Reinvest your offline Cash into more bombs the moment you log in to keep the chain moving.
Raiding and Base Locking
Once your income is stable, you can raid other players to steal their Cash. Raids are the fastest way to spike your balance, but they cut both ways: leave your base unlocked and someone will hit you right back.
The base lock is your only real defense. Lock it before you go raiding and before you close the game. The official description is blunt about it, warning players to lock the base before someone nukes them back. Treat that lock as a non-negotiable habit.
Raids reward you with a chunk of the target's Cash, which makes them tempting early. The math only works once your own economy can absorb a counterattack. A good rule of thumb: never carry so much uncollected Cash that one bad raid wipes out an hour of merging. Collect, reinvest, lock, then go hunting.
The lock isn't permanent armor. It buys time and deters opportunists, but a determined raider with a bigger stack can still come after you. That's another reason to keep merging upward. The richer and more locked-down your base looks, the less appealing you are as a target compared to the open, undefended bases sitting nearby.
Tips and Strategies
Most new players stall for the same two reasons: they hoard low-tier bombs and they raid before their economy can take a hit. These tips fix both and get you to the Mega Nuke faster.
Merge before you spend on anything else: Don't let duplicate bombs sit on your grid. The second you have two matching pieces, merge them. Chaining merges is far faster than buying a wider grid full of weak bombs, because a higher tier earns more from the same footprint.
Build a stable base income first: In your first 30 minutes, follow a clean path. Buy bombs, merge into a stronger nuke, lock your base, then attempt your first raid only once your Cash per second is steady. Rushing PvP before that is the classic way to fall behind.
Pick soft targets for early raids: When you do start raiding, go after bases that look weaker or unlocked. You'll learn the raid flow without risking a loss to a stacked opponent, and you'll bank some easy Cash to fund your next merges.
Always lock up before logging off: Your offline Cash is a target. If you leave the base unlocked overnight, you can log in to a raided, empty stash. One click before you quit protects hours of passive income.
Time your sessions around offline Cash: Because income accrues offline, a smart rhythm is to log in, collect, reinvest into merges, lock up, and leave. Come back a few hours later and repeat. You'll progress steadily without grinding nonstop.
Check in every Friday: Nuke The Game ships updates most Fridays, and those patches add new nukes, balance changes, and fresh codes. Logging in on update day means you grab new code rewards while they're live and adapt to any raid tweaks early.
Keep your grid full but not cluttered: Empty grid space earns nothing, but a grid jammed with un-mergeable single bombs is just as wasteful. Aim to always have at least one pair ready to merge. When you buy, buy in twos so you've got an instant combine instead of a lonely orphan tile waiting for a partner.
Bank a small Cash buffer before big merges: Some higher-tier merges and grid expansions cost a real chunk of Cash. Don't drain your balance to zero on a single purchase. Keep a buffer so a surprise raid doesn't leave you unable to rebuild, and so you can react when a Friday update shifts prices.
Mid-Game and Late-Game Priorities
Once you're sitting on a few B-tier nukes, the game shifts from pure building to managing risk. Your offline Cash becomes large enough that raiders actively look for you, so the lock matters more than ever. This is the stretch where consistent players pull ahead of the ones who binge for an hour and quit.
Push toward your first A-tier nuke as the next major goal. The income jump there is steep enough that it funds the rest of your merges almost on its own. From A-tier, the S-tier Mega Nuke is mostly a matter of patience and protecting what you've built. Don't get greedy with raids at this stage; a single careless loss of late-game Cash hurts far more than an early one.
Merge a Nuke Active Codes
Codes hand you free Cash and Nukes, which is exactly what you want for fueling early merges. As of June 11, 2026 there are two live codes, with a third going live on June 12 alongside the next update.
| Code | Reward | Status |
|---|---|---|
| UPDATE2 | 10,000 Cash + 10 Nukes | Active |
| BOOM | 5,000 Cash | Active |
| ATOMIC | Free rewards (live June 12) | Upcoming |
To redeem, open the game, click the Store button on the left side of the screen, scroll to the Codes section at the bottom, paste a code, and press Redeem. Codes are case-sensitive, so copy and paste them exactly. There are no expired codes recorded yet, so all three should pay out.
New codes usually drop on update Fridays through the Roblox game page, the Nuke The Game community group, and the official Discord. For the running list as codes get added and retire, check our Merge a Nuke codes page, and bookmark the Merge a Nuke hub for everything in one place.
One habit worth building: redeem codes the day they release. The ATOMIC code going live on June 12 is a good example, since the developer has noted that rewards expire after a while. Codes tied to a specific update can vanish once the next patch lands, so don't sit on free Cash. Grab it, then spend it on merges right away while your early-game gains compound the hardest.
If a code throws an error, it's almost always one of three things: a typo, a code that hasn't activated yet, or one that quietly expired. Paste rather than type, double-check the date, and if it still fails, the code has likely rotated out. We keep the dedicated codes page current so you're never guessing which ones still pay out.
What About Game Passes?
Merge a Nuke sells a handful of optional game passes through its in-game store, including convenience boosts like extra movement speed and a music boombox. These are paid with Robux, not Cash, and prices can shift between updates, so check the store's pass list in-game for the current rate before buying. None of them are required to reach the Mega Nuke, but a speed boost makes raiding rounds quicker.

Buy bombs from the shop, then drag two identical bombs or nukes together on your grid. They combine into a higher-tier nuke that earns more Cash per second. Keep chaining duplicate merges to climb from D-tier starter bombs up to the S-tier Mega Nuke.
Lock your base before you close the game or step away. The base lock is your only defense against raid theft, and forgetting it is the number one way new players lose Cash. Lock up before logging off, even for a quick break.
Yes. Your nukes generate Cash every second, and that income keeps accumulating while you are offline. Higher-tier nukes produce more Cash per second, so merging up raises both your active and offline earnings.
Wait until you have at least one mid-tier nuke and a passive income that can cover potential losses. Launch your first raid on a weaker or unlocked-looking base to learn the mechanic. Raiding too early, before your income stabilizes, is a common way to fall behind.
