Poker is largely luck based anyhow but the human element allows you to win with nothing at all, if Video poker were to miss out that element of the game its unfortunate because its alot closer to slots again anyhow. The one advantage slots can tout in its favor is that the money is contained in the machine from previous winnings and there is a payout ratio due, however I think the ratio is not per slot but the entire casino game or even people say the game ratio might be shared for a whole operator.
That's how it is with online slots, but I'm not sure how it works with physical ones. Anyway, we are talking about online slots here, right? So no one should expect a big win after a long losing streak. This is a big mistake which makes people to lose a lot of money in some cases. Not always, because you
can hit a big win anytime, and it can happen after a long losing streak too.

In my opinion, there are no similarities, each of these games has its own advantages in betting, sometimes this depends on each gambler, of course those who are more familiar with them will take precedence.
Regarding skill... I think poker is more dominant with additional skills and uses our brain to think more than slots.
But to myself... I prefer to slot games, because I'm more familiar with slots, and it's simpler, just pressing on without thinking more like in poker.
This thread is not about PVP poker, it's about
video poker, which is a very different thing.
