World Milestones
Understanding Rebirth Milestones
Farm World at 300 rebirths introduces the farming loop, Golden Machine, and Farm Eggs that fuel Desert and Nuclear progression. Nuclear World at 50,000 rebirths opens the nuclear chest and pet machine systems. Kingdom World at 5 million rebirths unlocks axe upgrades, clan houses, and wood farming that feeds Volcano content. Volcano World at 1.25 billion rebirths represents one of the largest rebirth walls in the game — plan potion stacks and auto rebirth sessions well in advance using auto click scripts or legitimate game passes.
Non-Rebirth Requirements
Hitting a rebirth milestone does not always instant-unlock a world. Farm needs 25 Forest Eggs. Kingdom demands an Atlantean Guardian hatch, five farm fruits, and thirty Aura Dice. Volcano requires three hundred Cave Eggs, a Royal Ruby, and ten potions. The calculator shows rebirth progress only — track other requirements through the world progression walkthrough and zone-specific guides.
Grinding Strategy by Milestone
- 0–300: Focus Click Multiplier, Rebirth Buttons, and Forest Egg hatching. Redeem codes for hatch potions.
- 300–50K: Farm automation and Desert egg sessions. See auto farm scripts.
- 50K–5M: Nuclear and Atlantis loops with aura dice accumulation.
- 5M–1.25B: Kingdom wood farming and Cave egg marathons before Volcano.
