Because the slot machines are created in favor of the owners, not the gamblers. I was thinking if that really exists, how this casino will even survive? No, those things are baseless and out of reality. Slot machine games are known to be pure luck-based games - I couldn't really imagine someone having the skill to defeat the slot machines. Because even if you spend many years playing them, you can't figure it out how it works other than having a huge chance to lose rather than winning.
It seems what you say is a little biased. yes, I don't understand what you mean by saying "Because the slot machines are created in favor of the owners".
however, if we talk about skill-based slot machines. it seems, we would very much doubt it. because, referring to some of the references that I read. slot machine games are strictly based on pure luck, even though they involve RNG and RTP. but in truth, it is hard to tell the difference between a game that is skill-based and a slot game that is purely luck-based.
And if, i referred to the link the first OP shared. As the article mentioned, skill-based slot machines are a new breed that are replacing the older semi-slot scenarios. however, it seems that basically the game types are the same. to be honest, I'm quite clueless about skill-based slot machines. even, if this actually existed. I'm interested to try it.
