Javascript percentage of winning algorithm
I have a slots machine game HTML5 + Javascript.
I have found the below algoritm on Stackoverflow, but i need another percentage
this.d = Math.random();
if (this.d < 0.3333) {
this.nextSymbols = [
['320', '320', 'jackpot'],
['jackpot', '320', '400'],
['320', '320', 'jackpot'],
];
} else if (this.d < 0.005) {
this.nextSymbols = [
['320', 'jackpot', '400'],
['320', 'jackpot', '400'],
['320', 'jackpot', '400'],
];
} else {
this.nextSymbols = [
[Symbol.random(), Symbol.random(), Symbol.random()],
[Symbol.random(), Symbol.random(), Symbol.random()],
[Symbol.random(), Symbol.random(), Symbol.random()],
];
}
I need to have:
1 of 3 spins to be a winning prize 2
1 of 200 spins wins big prize
Any math expert advice would be much appreciate.
Thanks

How is "I have 10 big prizes" relevant for the probability of a single spin?

<means less than. Soif (this.d < 0.005)means that the value is less than 0.005. Any value where that is the case is also less than 0.3333. However the if-test for <0.005 is in theelseclause of the <0.3333, so nobody will ever win the big prize.

To summarize - as @Bergi and @Richardissimo written in comments.
1 / 3 is 0.(3), but you can just write thid.d < 1/3 interpreter will calculate it for you.
And if you are making else if the second case will never fire. You have to change the order of conditions.
