I don't play slots, but I did manage an online casino for 3 years. Auto-spins allow users to play without "interaction" but, at least for my players, the animations and chirps were all part of the "fun".

All go towards the same thing - dopamine addiction as an activity.

I think I just wanted to say that the perception of a 90% "success rate" v's all or nothing with sports betting felt like a troublesome comparison, for me at least. These games arent safer or fairer at all - they are both doing the same thing - in different doses to different audiences.

Many of my slots players didn't consider what they did "gambling" at all.
