I don't know if this has happened to you much, but I usually play slots from time to time and when I get free spins I usually win something, sometimes more, sometimes less, but I always win. Today I got two rounds of 10 free spins playing Wild Bounty Showdown, and in the first one I didn't win anything, while in the second one I won about $0.34 (playing $0.20 spins). I felt a bit silly, because getting free spins is cool, it's usually exciting, and I've won some good big wins a few times.
Has anything similar happened to you?
Free spins also sometimes don't give anything, I've had several free spins but didn't get anything, although I've also had big wins but mostly not, but when I buy free spins it's more possible to get a decent win and it's more exciting than the free spins that come from regular spins.
The experience is quite strange because here lies the probability, the spins that are purchased are more likely than the spins that are given for free.
