💎 Premium Shop (Robux)
Limited-time eggs like the Dinosaur Egg are only available in the Premium Shop (left-side Shop button) and cannot be bought with Cash. These eggs go into your bag and can be hatched anywhere — and even gifted between players.
🎁 Free rewards
Some active codes give free pet treats and boosts that help you level pets faster. Redeem them before grinding.
Egg Slots: Unlock Prices
You start with 1 free egg slot and can unlock up to 5. More slots mean more eggs displayed per restock — which raises the chance a rare egg appears in the shop. Unlock them as a priority.
| Slot | Unlock Price |
|---|---|
| Slot 1 | Free (default) |
| Slot 2 | $500,000,000 ($500M) |
| Slot 3 | $25,000,000,000 ($25B) |

| Slot 5 | $1,000,000,000,000,000 ($1Q) |
Tip: the more slots you open, the more often rare and Epic eggs show up in the restock pool. Prioritize unlocking all 5 before chasing specific pets.

How to Hatch Eggs
Hatching mechanics
Buying an egg instantly triggers a spin wheel that rolls a random pet. Robux eggs go into your bag — equip them and left-click to hatch wherever you are.
Pet sizes
Every pet hatches in one of three sizes: Regular, Big, or Giant. Giant gives the highest multiplier and the strongest passive.
Leveling & limits
Pets level up to 50 using Cash. Each floor has a pet capacity, so manage your roster. The "+1 Pet Equip" Gamepass (799 Robux) lets you place two pets on the same floor.
Which Egg Should You Buy?
Pick your path based on whether you spend Robux. Either way, unlock all 5 egg slots first — it raises the odds of rare eggs appearing.
🆓 Free-to-play route
Grind Cash and target the strongest free pets.
- New player → save to $25B → buy the Rare Egg → target Polar Bear (Epic).
- Mid game → save to $25T → buy the Epic Egg → target Hydra (Secret).
- Keep all egg slots open so the Epic Egg appears more often.
💎 Paid route
If you are willing to spend Robux, the Dinosaur Egg is unmatched.
- Buy the Dinosaur Egg from the Premium Shop while it is live.
- Target T-Rex (Divine) or Velociraptor (Prismatic).
- Consider the "+1 Pet Equip" Gamepass to run two pets per floor.
🌱 General advice
Do this regardless of route.
- Unlock all 5 egg slots before chasing specific pets.
- Focus on growing Exotic and Transcended seeds to bank Cash fast.
- Equip Giant-size pets whenever possible for the best multipliers.
