About this app

<< Gacha Simulator (Normal) >>
◾️ About input items
[Provision ratio]
Enter the offer rate (appearance rate) of the desired character or item.
[Specific frame]
In the case of a continuous gacha that is drawn with a special setting that is different from the normal probability for one time, such as a high rarity confirmation frame, enter the special setting offer ratio.
It is not necessary to enter if all the offer ratios in the consecutive gacha are the same.
If the offer ratio is 0.5% for 9 times out of 10 consecutive gachas and the offer ratio for the remaining 1 time is 2.5%, enter "0.5" for the offer ratio and "2.5" for the specific frame. I will.
[Number of stations]
Select the type of gacha (1 time (single shot) or 10 consecutive gachas).
[Number of trials]
Enter how many times you want to draw the gacha. For example, if you want to play 10 consecutive gachas 3 times, enter "3" (please note that it is not 30).
◾️ About result display
The probability of winning N in the simulation result is exactly the probability of winning N. For example, in the case of 2 or more, the winning probability of N or more is the probability including exactly 2 pieces, 3 pieces, 4 pieces, and so on.
As a reference, it shows how many times you theoretically need to draw a gacha to get it with a probability of 50%, 90%, 99% respectively.

<< Gacha Simulator (back calculation) >>
◾️ About input items
[Provision ratio]
Enter the offer rate (appearance rate) of the desired character or item.
[Specific frame]
In the case of continuous gachas that are drawn with a special setting that is different from the normal probability for one time, such as a high rarity confirmation frame, enter the special setting offer ratio. It is not necessary to enter if all the offer ratios in the consecutive gacha are the same.
(Example) If the offer ratio is 0.5% for 9 times out of 10 consecutive gachas and the offer ratio for the remaining 1 time is 2.5%, enter "0.5" for the offer ratio and "2.5" for the specific frame. I will.
[Number of stations]
Select the type of gacha (1 time (single shot) or 10 consecutive gachas).
[Expected probability]
Enter the percentage you want to get. Calculates and displays the number of trials required to obtain with the entered probability.
For example, if you enter 50%, the standard number of times that "If you turn it up to that number, you can get it with a probability of about 1/2" is displayed.
◾️ About result display
Shows the theoretical number of trials required to win.

<< Box Gacha Simulator >>
◾️ About input items
[Number in Box]
Enter the number of all characters and items in the box.
[Number of hits]
Enter the number of characters and items you want to win in the box. * [Number in Box] Please enter the following numbers.
[Number of acquisitions]
Enter the number to remove from the box. * [Number in Box] Please enter the following numbers.
(Example) If you want to know the probability of performing a box gacha that can take out 10 pieces at a time twice, you will need to take out 20 pieces, so enter "20".
◾️ About result display
Shows the probability of hitting one or more. Also, if you hit more than one, the probability of hitting all will be displayed, but please note that it will not be displayed if there are many in the Box.

* The result displayed by the gacha simulator is a theoretical probability. I hope you can use it as a guide.
