All slots play to a pattern and if you play them long enough you can spot it
Batman and Catwoman Cash has 3 types of pattern play for example, it’ll play like its on meth with the features for about 150 spins, feature after feature after feature, then it’ll max its multiplier out at 5x and take the utter piss to even give a tease, take about 250 spins to give said 5x feature.. and its 3rd pattern of play is to go absolutely feral until the balance has been stripped away. I lost £82 last week on 25p spins without even a feature.. deposited a tenner a couple of days later and it banged in the feature within 10 spins lol.
I’m sure if I played DHV long enough I’d spot the patterns of play, because you need to remember they are programmed by humans, and so they ain’t going to be hard to work out if played enough haha.
