Reach 50 Plots First
Rebirth is locked until you own 50 plots. Keep expanding terrain even when cash flow slows — the 1.45x exponential scaling means each plot gets harder, but the 50-plot threshold is the only Rebirth unlock condition.
Hold $500M Liquid
The Rebirth reset costs a flat $500,000,000 Cash. Do not commit that cash to upgrades, enclosures, or eggs once you are within a few plots of 50. Keep the $500M liquid so you can trigger Rebirth immediately when ready.
Time the Mythic Egg Handoff
Hatch the Mythic Egg (500 Teeth, 5-minute incubation) right before triggering Rebirth. Mythic dinosaurs survive the reset, so a Prime Rex or Kraken waiting in your hatching queue pays off the moment Rebirth completes.
What Survives vs What Resets
Survives: Teeth, all Mythic dinosaurs (Prime Rex, Kraken), all Gamepasses, all Teeth upgrades (Permanent Revenue Multiplier, Hatch Speed, Offline Retention). Resets: Cash, terrain plots, standard dinosaur inventory, land expansions.
