Open toolWhy these tools only use your numbers
Steal an Egg's developer does not publish official drop rates, payout tables, or the steal formula — and any site that shows you "exact" percentages is guessing. We refuse to guess. Each calculator takes the numbers you can actually see in-game (a hatch rate you observed, the payout you just got, the Speed stats on screen) and does transparent math on them.
The formulas are shown next to every result, so you can sanity-check us: binomial odds for hatching, expected value for income, compounding multipliers for rebirths. If a game update changes how something works, the wiki article linked from each tool gets re-checked and dated — and the tool keeps working because it never depended on our guesses in the first place.
