The Nevada gaming industry is lobbing heavily to legalize them. So they can target younger demographics.

If I could loose money because I'm just unskilled at something (but had fun) rather than just got unlucky, I'd absolutely use one of those machines.

It doesn’t really work like that, eg if you play the quiz one, when you get past £3 the questions become ridiculous, like what is the size in cubic meteres of lake Victoria? 40040400303 40404940404 or 4940403030 etc

So it just ends up being luck really. They also pay out a fixed amount and the difficulty rapidly increases if you keep winning.
