It would be ideal if each slot would say how often each multiplier is hit on average, but speaking from experience, slots that have the highest multipliers don't have that of a steady pace for payouts.
This won't be good for the gambling providers and the casino.
Imagine someone gamble on x slots, they claimed 1K multipliers is usually happen after 10K bets, there's should be someone who will try to gamble until it reach 10K bets, if he didn't hit the 1K multipliers, he will scream both of the providers and casino scammed him.
Well, 10k bets is a lot... I guess there would be many bonuses along that way, but who knows how profitable those bonuses will be, in my experience, many will be under x10! Sometimes it can be really hard to hit x100... There are no guarantees when it comes to slots, what we can do is try and hope for the best!
Honestly speaking, based on my observation as a slot player for a long, volatility isn't a big deal now to most gamblers. Generally, if we do some interviews with some slot players out there, surely they will say that there's not much difference now between low and high-volatility slots as in the end, they will still experience being wrecked.
Sometimes, some gamblers are lucky at low volatility then unfortunate at high volatility slots, and vice-versa.
You described my experience. I had some pretty big luck with high-volatility slots, and many times I got wrecked playing low-volatility slots. The bottom line, if we are unlucky we will lose no matter what slot we choose!
In the end, I can only say that high volatility slots are much more interesting, with many more features and bonuses we can get. That comes with the price, as I always write, slots can give a lot, but they can take even more... keep that in mind.
