Rebirth — meaning in Roblox
Rebirth is the Roblox simulator mechanic of resetting progress in exchange for permanent multipliers — lose the numbers, keep the power.
Updated:
A rebirth (or prestige) trades everything you grinded — cash, tools, sometimes pets — for a permanent boost to future earnings. Each rebirth makes the next run faster, turning progress into an exponential curve.
Knowing when to rebirth is the core skill of simulator play: too early and you lose momentum, too late and you waste time at a plateau. Guides and communities usually publish optimal rebirth breakpoints per game.
