How the Roblox Grow a Garden Pity System Operates

The pity mechanic in Grow a Garden safeguards players from bad RNG streaks. If your client registers 99 consecutive egg opens without a Legendary or Mythic pet, your 100th hatch automatically triggers a Golden Pity animation.

Pro Tip for Efficiency: Never open Mythic Void Eggs without an active Ultra Luck Potion. Because the base chance for Secret pets is 0.1%, stacking an Ultra Luck potion (4x) boosts single rolls to 0.4%, reducing expected egg cost from 850,000,000 Shekels down to 212,500,000 Shekels.
