Income per Second & Value
Reference income
On the community reference value, Royal Sphinx is worth $280K/s — about $16.8M a minute, $1.01B an hour and $24.19B a day if the value holds. The next one down is Scorpion at $18.5K/s.
That is a reference roll rather than a promise: hatching returns a value inside a range, so a copy of Royal Sphinx can read above or below the figure listed here. The number is what this site holds for the pet, not a price anyone is obliged to pay in a trade.
Size and Mutation variance
This site prints no multiplier values for size or mutation, because none could be sourced. They stack on top of the base value rather than replacing it, which is why $280K/s is a floor-level figure rather than a maximum. The income calculator works from that figure, not from a guessed multiplier.
Rarity & Availability
Rarity label
Royal Sphinx is Cosmic — band 8 of the ten rarity labels this site uses. 20 pets carry it, 15 of them with a confirmed value. Rarity is a label rather than a ladder: it says how the collection files the pet, not what it earns. The whole band is on the Cosmic pets page.
Acquisition/source
It is an egg-pool pet, listed in the Desert collection — Early tier, and it opens at 10K Speed. The collection is described in full on the Desert page.
How to Get Royal Sphinx
Egg or event source
No source name is asserted here for Royal Sphinx — turning a collection name into an egg name is exactly the kind of guess that makes a pet page wrong. What is known is the pool: Desert, listed on the Desert table. The site prints no odds, because none could be verified.
Requirements/progression gate
Desert opens at 10K Speed, and its guardian is Scorpion. Eggs are opened on the map rather than from a menu, so a run that has not passed the gate cannot reach this pet at all. Its tier labelling is Early. The whole ladder is on the Desert page.
