Put what you give on the left and what you are offered on the right, then choose how to compare: money made, rarity, or a mix of both that you set yourself.

Add pets on both sides
The scale tips toward the side that makes more money per second.

What does the scale use?
You choose. Money made: the pets' real income (base income × mutation × size bonus). Rarity: the pets' rarity, availability, age and mutation (details just below). Both: we check which side wins on money and which side wins on rarity, then combine the two results; the slider lets you make one count more than the other. There are no official trade values yet, and trading is not in the game yet: once it is, what players want most will matter too. Fair = less than 10% difference. Every pet's value: the value list.
How rarity is compared
Every pet gets a rarity score. For reference: a Common pet is worth 1, a Divine you can still get is worth 512 (as rare as 512 Commons), and a limited Divine is worth 1,024 (as rare as 2 Divines). Weight does not count here. This is not an official value, just our rule, explained in full below.
1. Rarity
Each rarity is worth double the one below.
- Common1
- Uncommon2
- Rare4
- Epic8
- Legendary16
- Mythic32
- Cosmic64
- Secret128
- Eternal256
- Divine512
Monster pets have no standard rarity: they count as the rarity of pets that earn as much as they do.
2. Availability
The score is multiplied: the harder a pet is to get today, the more it counts.
- Availablex1
- Available on rotationx1.25
- Available in the shopx1.25
- Limitedx2
- No longer availablex3
3. Age
For a limited or no-longer-available pet: +10% per week since its release, up to +50%.
4. Mutation
A mutation also makes a pet rarer. These bonuses are not the income multipliers: mutations you can't get from a random hatch (events, shops) count x3.
- Rainbowx4
- Parasitex3
- Fracturedx3
- Scrambledx3
- Goldenx2
- Spirit Bloomx3
- Bloomx3
- Silverx1.5
Luminous version (1 in 100): x4, like Rainbow.

Never give first
“Give me yours first, I'll send mine right after” is the most common scam in Roblox games. Scams to know.
