why some slot games have features that seem completely impossible to trigger.

some of these slots feel like they’re trolling us with the bonus features. i see the symbols line up almost, or the third scatter teases for ages, then never lands. i get that there’s math behind it, but sometimes the advertised features pop off so rarely, i start wondering if they’re just there as bait. blackjack is boring sometimes but at least you know the odds and what’s in the shoe. do you think these hard-to-trigger slot features actually have any decent long term value, or is it just a distraction to keep us spinning?
