Despite my reservations, I decided to give it one more try last night because I was just one feature away from getting the "Wild Vine" spins, which I've never had before.
When I finally got them I was a bit excited... but not for long. I only got the Wild on reel 3 once - it gave me one more wild.. and $0.
So after
25 free-spins I "won" bet x 3...
I got the feature a few more times and it was a bit better, but the killer was the last one when I had good symbols on reels 1 & 2 and got the Wild Vine on reel 3; So it gave me 3 extra wilds - all on reel 5, which did not increase my win 1c.
It is now completely clear to me that this feature (just like Loki on TS2) is definitely NOT RANDOM!

Don't get me wrong, I'm sure the base game is random, but when it comes to the free-spin features I think the amount you will win is predetermined and not the result of random spins.
OK, at the end of the day it might make no difference, but I still don't like it.
