java calculate number of wins slot machine

On the other hand, I have tried dividing the 200-300 number by 40 (20 credits x 20 lines), in a surely misguided attempt at getting a reasonable number. When we run the simulations using 1 credit and 1 line, we get a Standard Deviation of 9, which multiplied by 1.65 (90% confidence) gives us a VI of 15, which seems a bit high but entirely reasonable. We have tried to calculate the standard deviation using simulations with 20 credits and 20 lines, and we always get a number between 200-300 (!). We are able to simulate all plays on the slot machine and record all pays.Ĭorrect me if I'm wrong please, but to calculate the Standard Deviation you have to first obtain the mean of all the machine pays for the lowest bet possible? In our case that would be 1 credit and 1 line. I've seen various documents on the web that state that for calculating this VI, it's necessary first to obtain the Standard Deviation for the Slot Machine. After some investigation I realized that, apart from calculating the RTP percentage, it would be nice to also calculate the Volatility Index (VI). Hi there everyone, first post here so don't be rough :)Īt our company we are currently building a simple slot machine as a mini game for giving players incentives for our yet to be released app.
