  1. 1

    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.

    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.

    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.

Spend remaining cash on Spawn Tier and Max Spawn upgrades before you confirm. Rebirth wipes your cash — anything left in your wallet is lost.
