I don't agree completely, as you say although everything is as random as it gets online, the newer slots on for instance MG, WMS, Netent and some other, do seem to have more built in near win displays.
It's a trend i also noticed, and i do not really like it: makes you want to autoplay and hide the screen at times
I suspect this is what game developers pay psychology and behavioral science students and/or institutes big bucks for, to come up with, but i am devoid of proof.. whichever the case, i have enough spins on my counter to justify what i said: newer releases have more near big win or near win displays somehow built in to their game play, and i really don't their it would affect the RTP and randomness, but it does irritate me.
Every time i see it, especially when on a bad run, i get the strong feeling "they really want me to think it's coming anytime now" and this does not increase my desire to play on really.
Could be wrong, but i don't think i am
