It is a shame, that's gambling though, people are addicted to that dopamine rush of those small wins and the chance at hitting a big one.
I've watched people play those things for hours on end... I still don't fully understand it myself. I always get sick to my stomach when I bet more then a 100 bucks.

yeah it depends on what type of slots you get, I think. the ones that are federally regulated ( like the ones you see in vegas) are probably stupid expensive.

here are the ones we see here (cabs)

or

you can buy IGT machines which look more like the ones your see in vegas… they might even be the ones you see in vegas. there are a few bally's for like 1500 bucks.

new probably, used they cost 1500-3k

the grey area machines new cost 3-6k
used they cost 100-1500

as you can tell they don't retain their value at all.

there is another bar in the same center as my place and they have like 7 old casino games (the real flashy kind with beacons etc.), personally I don't like that type.
kind of makes a place look a little trashy.
