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.
