Rebirth is part of the official progression loop, but exact requirements, reset losses, and benefits are not publicly documented. Use the current in-game confirmation screen, record your cash and collection state, and do not confirm until the tradeoff is clear.
A rebirth can accelerate long-term progress only when its benefit outweighs what resets. Because that formula is not public, this guide focuses on a repeatable in-game preview check instead of a guessed threshold.
