About this game
Let's calculate the probability of winning in lottery or gacha!
Calculate the probability and spin the gacha efficiently!
This app is an app that allows you to calculate the ``probability of winning'' and ``number of times required to win'' in lottery games, gachas, etc.
■Probability of winning
Calculate the probability of winning from the appearance rate (winning probability) and the number of trials.
You can see the probability of winning at least once out of the number of attempts.
example:
Appearance rate (probability of winning) 1%
Number of trials: 100 times
Probability of winning → 63.396….%
■Number of times required to hit
Calculate the number of trials required to win from the appearance rate (winning probability) and the expected probability.
You can see how many times you need to draw to win with a higher probability than you expected.
example:
Appearance rate (probability of winning) 1%
Expected probability: 90%
Number of trials required → 230 times
