This calculator is arithmetic on a table, not a live mixer. Enter quantities from your own [🕰️] Catch And Tame! session. It will not click the shop.
Drop probability
Breeding attempt odds
Chance of at least one success across independent breed attempts. Type your own percent. The form does not know the game's real rate.
Chance of at least one success = 1 − (1 − chance per attempt) raised to the number of attempts.
50% and 10 attempts are worksheet placeholders, not a drop rate. Giraffe is only described as a low chance on the main table. Another list prints 9% for Alligator + Capybara and 0.3% for several Mythic pairs; those percents are not confirmed here. The math ignores cooldowns, Twin Eggs, and weather.
Upgrade payback
Unlock payback
How long an unlock takes to repay itself from extra Bucks per minute. You enter the cost and the income.
Payback cycles = upgrade cost ÷ extra profit per cycle, rounded up.
Sample only: Prehistoric Zone is listed at $500,000 and Triceratops at 114 BPS. 114 Bucks per second is 6,840 Bucks per minute, so the sample cycle is 1 minute. It assumes the pet stays penned the whole time and ignores mutations and Money Boost.
