Can someone here who knows these things too well enlighten me if there's a difference between spins in a normal game and spins in a bonus game? Does each have their different RNG formulas?
I play slots a lot longer than you... and I have experience with almost all providers (good & bad). I had many big wins from normal spins, many like zillion, up to x200. And I experienced many under x10 bonus wins... a bunch of them under x5 and x0.
In the bonus round, the chances for us to win something big are pretty high... but only if we are lucky. As I wrote we can hit a bonus round and win almost nothing, or in the worst case nothing (x0). If we are lucky we will hit something huge, but that rarely happens.
I don't wish to scare you, but 200 spins is nothing... even when x2 chances to hit a bonus round is activated. I experienced up to 400-500 spins without hitting a bonus round, and from some discussions, I found out that some people didn't hit a bonus round even after 600-700 spins.
Slots are tricky... many times I won a bonus round in the first 10 spins. The more you play them the more confused you will be, until you learn the truth that slots are all about luck. I like to test my luck with slots, and if I am lucky I know how generous they can be... but if we are unlucky we will just burn out any balance we have. One thing I always say is "if you are not ready to lose your balance don't play slots".
One member of this forum is buying just "super spins"... he doesn't even bother to buy normal bonus spins. Those super spins are also super tricky, they are expensive as hell, but with them, the chances for some high multi are rising... I saw his bets, 4-5 super bonus gave nothing...but the next one gave a decent amount. So even those are all about luck, and you need to have a huge balance in order to endure all bad ones until you win something.
Bottom line... there's no bottom line about this matter except what I said, when someone decides to play slots he needs to be ready to lose the balance. If you are not ready to risk all you have don't bother to play. And when we play slots it's the maximum risk we can take.
