1. Expected Value Of Slot Machines

After inserting all $100 into the slot, 100 pulls later you’ll end up on average with $90, because you lose 10 percent of your money. If you run the $90 back through the machine, you’ll end up with 90 percent of it back, which is 0.90 x 90 = $81. If you run that amount through in 81 pulls. Expected Value. Anyone do the math for the expected value on any games? I know HBHB is about 95% win back rate. What about congo cash? Also I doubt it, but is there any real world slots with a hyper bonus feature like in many of the app slot? Save hide report. For example, a high variance slot machine is a high risk slot, and a low variance slot machine, is a low risk slot. Slot games which have a pay-out percentage of between 93% or higher, are known as low variance slot machine games. Those slot games that have a pay-out percentage of 92% or lower.

The simple formula is [number free spins]*[average return from each free spin].
In the Atkins Diet machine the number of free spins is not obvious. You start with 10, but free spins can earn more free spins, infinitely. In that case, the expected final number of spins is n/(1-n*p), where n is the number of free spins earned per bonus, and p is the probability of the bonus per spin. In the the Atkin's case, the bonus probability is 0.011185, so the expected number of free spins per bonus is 10/(1-0.011185*10) = 11.259335.

Thanks, I will try with that and return here if I get stuck.

My question is about different number of free spins when you have different number of scatter symbols visible. In the Atkins Diet machine, for each number of visible scatter symbols (3, 4 or 5), the player is granted with the same number of free spins (10 free spins).
How can we calculate the expected number of free spins if for example:
for 3 scatter symbols you win 5 free spins (probability to get 3 scatter symbols is p_3)
for 4 scatter symbols you win 7 free spins (probability to get 4 scatter symbols is p_4)
for 5 scatter symbols you win 9 free spins (probability to get 5 scatter symbols is p_5)?

The expected number of free spins for 3 scatter symbols is 5/(1- (p_3*5 + p_4*7 + p_5*9)).

How the [average return from each free spin] is calculated?
It is (total number of hits) * Sum (EV) / Total Slot combinations ?
or Sum ( Return of each combination * P(comb) ) / Game Total Hits ?

I'm not totally sure what you mean by 'game total hits,' but these sound to me like they'd be the same number.

I think I know what he's getting at. I glossed over this post.
Anyhow, the return of a slot game, which is the same calculation used for the free games is: Sum (Return of each combination * P(comb)).
P(comb) = hits(comb)/total slot combinations

Using this formula I can calculate expected number of free spins for 3, 4 and 5 scatter symbols, separately.
But, how can I calculate the expected number of free spins for the game?
Is it (5+7+9)/(1-(p_3*5+p_4*7+p_5*9))?

No. The prior formula gives you the expected # spins starting from the given feature trigger, so just weight each number by the odds of each trigger.
But I typically wouldn't do that aggregation without computing the individual results first. I'd recommend keeping things broken out and computing RTP based on each individual feature trigger.

What should you look for when you want free slots? A friend of mine told me once that these kinds of slot machine games on the Internet are like Angry Birds—they kill time, and they’re mildly diverting, but you don’t really get much out of them. I used to compare them to beer without alcohol. Since there’s no money on the line, free slots don’t make much sense. Or do they?

A good free slots site should offer both 3 reel and 5 reel games, preferably several of each, with various themes. These games should also feature decent animation. If you’re playing this kind of game, there is some kind of sensory stimulation that you’re after. So find a site with lots of bold colors and sound effects. Free slots webmasters should try to make your experience as vivid and realistic as possible. You should also expect these games to load fast. You shouldn’t be required to download any software in order to play, either. In this age of ubiquitous high-speed connections, playing slots for free should be as simple as clicking an icon on your screen.
