A lot has changed with online slots and depending on the juristiction your playing in : it is significantly worse I could talk for hours on the subject but in summary
the less lines the less the volatility watch out for high variance slots because there are so many nowdays just remember the rule the high the variance the higher the risk
these days I drift between quickfire , pragmatic , and call me deranged but netent too even with all the changes .
I noticed behaviour changes with many slots win streaks won't be prolonged anymore they are short lived / lightning quick I've seen no static activity across many platforms ,
win intensity strikes are becoming lesser and lesser or rare high volatility strikes which I would liken to a winning the lottery strike these days lot of money chewing games out there
its always been the wild west that said but I swear its 10x wilder boasts of 30,000x the bet etc etc great in theory but it can make bankrolls vanish with the wave of a wand .
Also the majority of wins i've had are with E-COGRA certified casino's its to the point where if the place isn't legit certified with them im closing accounts seen
too much low RTP activity to ignore at this point .
