How the merge system works

Step

In short Merging two nukes of the same tier into one higher tier is the core action that drives everything else in the game.

You start with a Tier 1 nuke. Pick it up, wait for a second nuke of the same tier to appear, then move one onto the other to combine them into the next tier up. The higher the tier, the more cash per second that nuke generates. Every tier has its own name — Tier 1 is Lil Boomer, Tier 2 is Spark Popper, and so on up through hundreds of tiers.

Pick up a nuke lift it off your base so you can move it.
Wait for a match a second nuke of the exact same tier must be present before you can merge.
Combine them drag one onto the other to produce a single nuke one tier higher.

Cash income and offline earnings

Summary

In short Your nukes earn cash around the clock, so your tier level directly sets your income rate.

Each nuke produces cash every second equal to its tier number, and Rebirths multiply that rate further. Because earnings continue while you are offline, logging in regularly to collect and reinvest income helps you grow.

Cash rate　one unit of cash per second per tier number, before any Rebirth multiplier.
Offline income　nukes earn even when you are not in the game.
Rebirth effect　each Rebirth multiplies the cash-per-second you receive from all nukes.

Raiding other bases and defending your own

Tips

In short Raiding is a major income source, but leaving your base unprotected hands that same income to your enemies.

Launching nukes at another player's base lets you steal their cash. The risk is retaliation. Managing how much cash sits in your base at any moment is important.

Tips worth knowing

Lock your base before you go offline or step away so nobody can raid you while you are gone.
Spend large amounts of cash on new nukes immediately rather than sitting on it, reducing how much an attacker can steal.

Rebirth system

Check

In short Rebirth resets your progress in exchange for a multiplier that makes every future nuke earn cash faster.

The tier list is divided into Rebirth brackets — Rebirth 1 nukes begin at Tier 1.07B, Rebirth 2 nukes at Tier 34.36B, and each bracket continues the pattern. Reaching a new Rebirth bracket unlocks nuke names and damage values that were not available before.

Rebirth 1 begins at Tier 1.07B (The Null Throne).
Rebirth 2 begins at Tier 34.36B (Hollow Star).
Rebirth 3 begins at Tier 1.1T (Threadcutter Prime).
Rebirth 4 begins at Tier 35.18T (Worldspine Sundered).
Rebirth 5 begins at Tier 1.13Qa (Beyond the Veil's Veil).
Rebirth 6 begins at Tier 36.03Qa (Silent Strike).
Rebirth 7 begins at Tier 1.15Qi (Godhammer).
Rebirth 8 begins at Tier 36.89Qi (Mech).
Rebirth 9 begins at Tier 1.18Sx (Sci-fi).
Rebirth 10 begins at Tier 37.78Sx (Arcane).
Rebirth 11 begins at Tier 1.21Sp (Starry Night).
Rebirth 12 begins at Tier 38.69Sp (Greek).

Common questions

FAQ

How do I make more cash per second?

Merge your nukes to higher tiers, since each nuke earns cash every second based on its tier number. Completing Rebirths multiplies that rate across all your nukes.

Can I play without spending Robux?

The offline income system and merge loop are available to all players equally, and free codes from the official group add extra resources regularly.

What should I do when I keep getting raided?

Lock your base whenever you step away, and spend your cash on nukes as quickly as you earn it so there is little for raiders to steal.

Where do I find codes to redeem?

Join the game's official Roblox group, where codes are shared alongside update announcements. New codes arrive on Fridays with the weekly update.
