Since my time playing slots games, i haven't won very big amount from free spins, my normal spin or automatic spin has given me more wins than when i get free spins, either from Bonus buy. I remembered getting 15 free spins on a $0.2 bet, all i got after the 15 spins were concluded was $6.27, truly i expected more since it was a free spin and should come with higher chances of winning, realizing that it was just some normal spin and has no extra feature to win big. Free spins give multiple wins on one bet amount, which is the advantage.
That's understandable because I think almost everyone feels the same way

Free spins are just a form of fun but regardless of how small or big the win is it's still worth being grateful for because after all we can't expect to get big expectations for this although there may be some possibilities that occur for big wins but of course we realize that winning with an average nominal amount is a common thing that happens for free spins.
It would be quite naive of me to try and expect a big win but it's from free spins, not that I don't want to feel that way it's just that the chances are very slim.
It is very convincing when we buy a bonus feature or get free spins for free, but the winnings are the same as the regular spins we do. However, some people can indeed get maximum wins from free spins.
However, psychologically, when we are in a free spin, great hope will arise. We hope that luck will come to us this time so that we get a big win or even a maximum win. However, when we are lucky and get a big multiplier, each spin will feel a very different sensation and it is tense.
