Separate four different things
| What you see | What is confirmed | What remains unknown here |
|---|---|---|
| Rarity tier | Six tiers are named in official first-hatch badges: Common, Uncommon, Rare, Epic, Legendary and Mythic. | The hatch probability for each tier. |
| Coat and eye size | The developer says these are random. | The complete options and whether an appearance changes earnings. |
| Trait | Traits are random; some are described as ultra-rare with 1-in-X labels. | The full trait catalog, exact effects, and whether rolls are independent. |
| Shiny | Shiny variants are mentioned by the developer. | The shiny chance and whether shiny affects race results or cash. |
How to use an in-game 1-in-X value
If the current game screen shows a 1-in-X chance for one specific outcome, enter that number in the hatch odds calculator to see the mathematical chance across repeated independent attempts. Check which egg, trait, event and boosts the number applies to. A shiny chance multiplied by a trait chance would require evidence that those rolls are independent; this wiki does not assume that.
Compare the horses you actually have
Use the personal horse tracker to record the tier, exact in-game trait label, shiny status and race wins of each horse. The log stays in your browser. This helps you compare your own horses without turning one result into a global drop-rate claim.
For the six sourced tiers and their badge links, see the rarity reference. Review date for the official game description: September 23, 2026. A screenshot or repeatable in-game observation is needed before adding numeric trait, shiny or performance tables.
