I think it's a matter of the user and not necessarily the game itself. I've tried both and have won considerably and lost as much as I think a regular gambler would lose on such games. Perhaps you're just attributing causality on things that aren't even connected in the first place. In any case however, some game companies increase the RTP for their newer games in order to entice customers, but it will still boil down to whether you are lucky, nothing else.
I have been playing a few slots lately and have had some good winnings but nothing huge yet. Most of the YouTube gamblers I watch have been playing Sweet Bonanza, so I tried it first with a minimum bonus buy of $20 and sometimesi got into the bonus after few normal spins. The maximum win I had was x7 which is x700 on the game.
I also tried Gates of Olympus, Sugar Rush, and Sweet Bonanza Xmas, but I didn't like any of them. I don't know if I just got used to Sweet Bonanza or if there are other better slots out there. Could you please recommend a good slot with bonus buys and low cost, if possible?
Personally for now I would put Sweet Bonanza as the best slot and Gates of Olympus as the worst one as i never had any winning session with more than 10 bonus buys.
I don't think that there are best or worst slots, still boils down to RTP and the user experience. That's why this developers is offering us "x" theme slots because it's up to our preferences.
As for those Youtube gamblers that are winning bid, it's hard to replicate those because in the first place they have a big bankroll and they will just opt to take advantage of the buy bonus. But still though, not recipe for a good win, most of the time, either huge win or buy bonus strategy sucks as you can recoup what you have paid as the games won't give you what you expected.
Exactly, and I wouldn't really trust YouTubers and streamers when they are advertising gambling sites or games, or even just outright playing with these games, most of them are sponsored in secret by the gambling site itself, and if they weren't, they're playing on a big bankroll as you have stated, so they don't really speak for nor represent the average gambler, experience and opinion-wise.
