01Choose the egg, pet and size separately
The Common Egg reference groups Normal, Big and Mega under each pet. They describe the size outcome. A normal-size Unicorn target uses the reported 0.3%; a Big Unicorn target uses 0.006%. A different egg has its own distribution, so do not transfer Common Egg figures to an Epic Egg.
- Match the actual egg and exact pet-size outcome.
- Do not multiply a listed size-outcome rate by another guessed size chance.
- For an earned egg, enter zero purchase cost while still considering the random outcome's opportunity cost.
02Set the stop before hatching
Low odds can consume the money that should fund seeds. Decide the maximum number of rolls or total cost before the first hatch, then return to the pet ability page if the target does not appear.
- Probability is not a pity counter.
- The theoretical average is not a promise.
- A budget stop protects the main route.
03Compare rolls with the next crop
The right hatch limit depends on what the same Sheckles could do elsewhere. If a few rolls would fund a repeat crop or a missing defense item, treat that opportunity as the stop condition rather than chasing a low percentage.
- Set a roll limit before opening the egg.
- Compare total hatch cost with one crop cycle.
- Stop when the pet would delay the main route.
04Separate a probability plan from a collection goal
A hatch plan answers how much risk you will accept; a collection goal can continue indefinitely. Keep those goals separate so a missed target does not silently raise the number of rolls you were willing to buy.
- Write the maximum rolls first.
- Stop at the planned cost even after several misses.
- Return to Pets to check whether the target still fits the route.
05Turn the live odds into an affordable stop
A chance calculation is useful only after the exact pet is confirmed in the egg currently shown. Enter the live percent and one-egg price, subtract one planned seed from the wallet, and compare the affordable hatch count with your chosen limit; the tool flags a plan that would cross that reserve.
- Do not use a remembered pool or price.
- Keep one crop restart outside optional hatch spend.
- Use the smaller cap and stop even if the target has not appeared.
Probability boundaries
More rolls increase chance, not certainty
The examples show how a low per-hatch probability behaves across several independent attempts without promising a result.
30% target, 3 hatchesp = 0.30, n = 365.7% at least oneThis is a chance, not a guarantee.
0.3% target, 10 hatchesp = 0.003, n = 10About 3.0% at least oneSet a stop before spending because most runs still miss.
Probability boundaryOdds are update-sensitive and never guarantee a target. Use the current pool and a player-entered cost when setting a hatch limit.
