This calculator is arithmetic on a table, not a live mixer. Enter quantities from your own Steal ASMR! session. It will not click the shop.
Drop probability
Lucky Spin hit chance
Enter one documented segment chance and how many spins you will take. The result is the chance of at least one success if each spin is independent. Default 8 is Instant Hatch, not every prize.
Chance of at least one success = 1 − (1 − chance per attempt) raised to the number of attempts.
Type 20, 7, 25, 8, or 4 only when that percent matches a prize in the Lucky Spin guide. About 7 for Rainbow Dumpling is approximate. Do not enter a percent for 6× Treadmill. The two unnamed wheel segments are not inputs.
