There are times when Pragmatic Play games is not stingy, sometimes with just a couple of normal spins, you can hit a bonus round and that bonus round often times gives the gamble 500x plus wins. There are also times that Pragmatic Play will not give us good result, even with 2000 to 3000 normal spins, it won't give us scatter for bonus round.
So the results are uncertain following our luck playing that slot from Pragmatic Play but I agree with you that sometimes we can hit a bonus round which can bring big multiplier. But I am not yet hitting 500x if I am not mistaken and I also never roll until 2000 or 3000 normal spins. That is too much for me.
Yeah, Pragmatic Play result is uncertain, if you happen to watch streamers that frequent Pragmatic Play games, you will see how random Pragmatic Play is, sometimes they get a max win after series of losing bonus buys, while often times, they get busted in just a few minutes.

About your luck on this provider, I believe you'll eventually get your 1000x+ multiplier because the slot result is random, and this means there is always a possibility that the next spin can surprise us.

So when you already win, you must quit immediately before the situation change and you losing all of the money including the money you win. That is the best strategy ever for gamblers to avoid big lose and could enjoy the win money.
That would be the best move. I have my own experience of not quitting when I already 5x my bankroll and stayed on the same game for hours, I ended up with extra top up and eventually 0 bankroll lol.
The important thing that we must always remember is when we win big, we must stops gambling and leaves the game. Don't even think to moves to other slot games because our luck might leaves us along with the last winning we get.
Yeah, but sadly in the heat of the wins, I always forgot that lol.
Thank you for your suggestion, maybe I will try it later to play PG Soft and see how good my luck. If the bonus buy is not too high, maybe I will take it and see.
Yw, and I think PG Soft bonus buy is not that expensive, some cost 75% of 100 normal spins. But if you are new to this provider, I suggest to try normal spin first. There is a huge possibility to trigger bonus round during the early spins of your session.
