I do not think that the free spins have some great probability for winning than regular rotations.
I believe free spins are just like regular spins, you just get them for free. When I play slots, I usually go for the bonus buy, which gives some free spins, and honestly, it’s no different from betting a fixed amount and hitting auto-spin. If you’re lucky, you win, simple as that.
Games like this aren’t something to overcomplicate as it’s pure luck. Your only real chance to win is if luck’s on your side, so there’s no need to overthink slot probabilities or whatever.
Sorry but I also believe that free spins have absolutely lower probability of winning anything significant with them than regular bought spins..
You are talked about always going for a bonus buy when ever you play slot games, which give free spins, this free spins are different from the free spins I believe we are talking about, a free spin you get for buying a bonus inside a slot game is not considered free spins in real sense if you ask me, I usually see this as buying bulk spins at a little lesser rates from each rather than paying for each spins separately as we go in the game.
The type of free spins we are talking about here are those type we get from the casino for doing almost nothing, maybe the casino just awarded some users free spins as a way to motivate them to try the casino, or to try some certain selected number of games, this type of free spins usually come with some conditions that must be meet like wager requirements and so, this is not the same as free spins we get when we buy a bonus in the middle of a slot game, this type of free spins usually don't come with any special conditions like wager requirement or whatever.
