To each their own I guess, but I do not really gamble at slots as at least to me it is a very boring game, as you barely do anything except placing your bet and pushing a lever or pushing a button, so I could not picture myself watching someone else streaming about it as that would be without a doubt even more boring regardless of how interesting they tried to make it to be.

Personally I prefer games like poker or blackjack in which you really need to think about your next movement instead of relying solely on your luck, as it is the case of slot machines.
