Open the Rebirth menu when income plateaus
Find Rebirth on the left side of the screen once your cash/sec stops climbing from merges. Resetting too early throws away progress — wait until the next tier barely moves the needle.
The Rebirth panel shows your next bonus — compare it to how long this run took.Watch at 0:45 - 2
Lock your base before confirming
Rebirth clears your nukes and cash, but other players can still hit you mid-session. Lock before you open the menu and again before you log off after rebuilding.
Lock protection is separate from rebirth — do not skip it.Watch at 0:15 - 3
Rebuild with your multiplier and extra nukes
After resetting you keep the permanent cash bonus and any extra nuke slots. Merge aggressively — the multiplier makes each tier jump faster than the run you gave up.
Post-rebirth merges should outpace your previous run if you reset at the right time.Watch at 1:00

Frequently Asked Questions
When should I rebirth in Merge a Nuke?
Rebirth once new merges and upgrades barely raise your cash/sec. Resetting too early wastes the progress you clear — the permanent multiplier only pays off if you play long enough to climb back.
What should I buy before rebirthing?
Spend remaining cash on Spawn Tier and Max Spawn upgrades before you confirm. Rebirth wipes your cash — anything left in your wallet is lost.
Where are the rebirth tier requirements?
Published requirements and cash bonuses for Rebirth 6–10 — including the Rebirth 8 Overclocker and Barrier gate — are on our Rebirth Guide page with the full table and payback calculator.
How often can you rebirth?
Rebirth unlocks once you meet the cash requirement for the next tier. How quickly you can chain rebirths depends on your cash rate and any boosts — the exact cooldown or limit is Pending. See /rebirth for the full tier table.
Does rebirth reset my cash multiplier or game passes?
Rebirth is designed to reset most progression for a permanent bonus, but the exact list of what resets versus what persists (passes, codes, mutations) is Pending — confirm in-game before you reset.
What speeds up reaching the next rebirth?
Higher-tier nukes raise your cash/sec, and active codes give free cash and boosts. Grab current codes at /codes and plan merges with the /calculator before rebirthing.
