This time, no matter how hard I tried, I didn't manage to get that 100x. I think it was several hundreds tries in total. There were multiple 10x like this one



but druring more than 30 minutes of playing, 100x didn't appear even once. So, I dropped it and switched to another challenge run by magnificent SanjaT,  Slots Forum Challenge | Week 27, and I've had some success there with Book of Huli slot by Truelab.

First I won 10 Free Spins



and then another 10 Free Spins within those free spins, and with 20 free spins I won a pretty good amount out of my 20 cents bet:



I was 555.50x of my bet



and I can't be not happy about it.
