Ride A Pet Hatch Calculator: Odds & Luck
Free Ride A Pet hatch calculator: work out your real odds for Kitsune, Phoenix, T-Rex, Unicorn or any 1-in-N pet, with luck stacking and egg budgets included.
Last updated:
Every rare pet in Ride A Pet is a 1-in-N roll, and every luck bonus divides that N. This calculator turns both into plain numbers: your effective odds with a luck stack active, your chance after a planned batch of eggs, and how many eggs a 50% or 90% shot really takes. It runs entirely in your browser — nothing is sent anywhere.
Chance in 100 eggs
0.0000%
Effective odds: 1 in 1 quadrillion (Qi)
Expected eggs needed: 1 quadrillion (Qi)
For 50%: 693,701,640,907,262 eggs · For 90%: 2,304,426,970,399,298 eggs
How to use your result
- The "chance in N eggs" number is the honest one. A 2x luck multiplier halves the odds but does not make a 1-in-30T pet "likely" — run Phoenix at 100 eggs to see why batching without stacked luck is the expensive mistake.
- Expected eggs is an average, not a promise. Dry streaks past the expected value are normal variance; the community's 100-egg Dragon sessions are textbook examples.
- Compare pets before committing. The gap between Horse (1 in 500K) and Unicorn (1 in 1T) is why the rebirth chain comes together naturally while the Ethereal chase takes weeks.
Where the numbers come from
| Input | Value used | Source and confidence |
|---|---|---|
| Kitsune base odds | 1 in 1Qi (quadrillion) | Community stat sheets, multiple guides |
| Dragon base odds | ~1 in 7Qi | Unconfirmed — community videos only; shown for comparison |
| Phoenix | 1 in 30T | Fandom stat sheet + trackers |
| T-Rex | 1 in 10T | Fandom stat sheet + calculator site |
| Unicorn | 1 in 1T | Fandom stat sheet |
| Horse | 1 in 500K | Fandom stat sheet + roster guides |
| Luck model | Effective odds = base ÷ multiplier | Community model — the game has not published its formula |
Each pet's page carries the full stat table and confidence notes. Where sources disagree, the pet pages say so — this calculator inherits those caveats rather than hiding them.
Frequently asked questions
How many luck points do I need for Kitsune? There is no confirmed number — luck's exact formula is not public. The practical answer from the community: activate every layer you can (group +40, event windows, boost items) and treat the project as weeks of batches. See the Kitsune guide for the stacking checklist.
Does the group bonus (+40 Luck) double my odds? Unknown exactly — the community commonly treats +40 as roughly a 2x baseline, which is the calculator's default comparison point. The honest label is "directionally right, not officially confirmed."
Is this calculator official? No — it is a fan-made tool using community-verified base odds and a simplified luck model. No account data is used or sent anywhere; every calculation runs in your browser.
Why does the Dragon use unconfirmed odds? The ~1 in 7Qi figure circulates in hatch-attempt videos without a maintained stat sheet behind it. It is shown so Dragon budgets can be compared with the confirmed pets — read it as an order of magnitude. The Dragon Egg guide explains the discourse.
Can I share my result? Yes — the copy button produces a link with your pet, luck, and egg count baked in, so the exact calculation opens for whoever you send it to.
