Rebirth Guide
Everything about Rebirth - the 500M power requirement, what resets, the permanent rewards, and when it's worth doing.
Overview
Rebirth is the endgame reset in Merge a Black Hole. Once your total black hole power reaches about 500 million, you can rebirth to reset your holes and progress in exchange for permanent boosts and new content. It's the goal after reaching the Omega Hole.
What Rebirth Does
Rebirthing wipes your current black holes and base progress, returning you to an earlier state. In exchange, you gain permanent boosts that make every subsequent run stronger and faster.
Because the boosts persist across rebirths, each cycle compounds - experienced players rebirth repeatedly to stack rewards and push deeper into the merge chain.
Rebirth also unlocks new content not available in a first playthrough, giving long-term players fresh goals beyond the initial climb to the Omega Hole.
