It's quite addicted :v
I tried it already several times, around 200 spins per session but I got no FS till now. Not a type of slot that I like to be honest but I do like to try new slot games especially from Pragmatic and Play'n Go. Few days ago I endorphina games with buy features and I have to say it is better than most other buy features as it is rare to get ZONK (less than 50% back) but indeed it is a big hard to get big win but I can say that it is profitable.
