So my question is:
(1) Is there a logical reason behind why slots make x10 feel easier to achieve?
(2) Or maybe it’s just a psychological trick because slots are designed to keep giving “small wins” to make us feel engaged?
This is psychological matters, note, you don't win the slots games with your logic because it is almost a zero skill to say... Your experience does not guarantee your success.
So if you are ever lucky to win a small odds and seemly likely easier (not possible), you have to be thankful because you will either be chasing low odds while the RNG is outcoming higher odds and vice versa is so on the outcomes in whatever your decisions maybe will be determined by the RNG.
So, hitting a X10 in the slot games is not as easy to be compared to sports bets. The risks at all still lies on luck and if it is true that winning on bigger odds in the slot is as easy as that, I bet the sport bets will loose customers because what slot and sport bets players are doing is chasing the wins if not higher odds.
